Maximus IV Extreme Bios and Sandybridge CPU Overview.
(Remember you Overclock at your own risk. ASUS is not held responsible for any damages that may occur)

******UPDATE******
NEW BIOS -RAJA@ASUS
1409 , changes Over 1407 – adds bios rom flash back -> from one rom to another -> to fix problem of BCLK unable to change.
‘System will shutdown to do BIOS Flashback. Do not turn off AC while you see the ROG Connect LED blinking. It will take up to 8 minutes, please be patient.’

******UPDATE******



First off, all ASUS P67 (sandybridge) motherboards now use a UEFI graphic user interface BIOS. This means you have a clean GUI layout with mouse support. We'll go through the bios screen shots along with some sandybridge cpu info

EZ mode is pretty easy. In a clean ROG theme, it simply shows you the important information you need like; Motherboard name, bios version, CPU type, memory type, cCPUfrequency, language options, CPU/MB temperatures, Voltage for the CPU your PSU voltage, and Fan speed. You also have a quick system performance for the novice for energy saving mode (basically down clocking your cpu), normal mode, and high performance (slight overclock)
493

You can also drag and drop your boot priority with your mouse. whether you have an optical drive, ssd, hdd, usb, etc. Just drag and drop in the order you want it to boot.
494

In Advanced mode, you get all of the features you would normally see in a bios but with the ROG theme and tweakable options.
495

CPU Level up gives you a quick overclock for your CPU. typically 2500k and 2600k can usually hit up to 4.8-5.0 ghz, this still gives you a safe range with auto settings.
496

Turbo Ratio allows you to set individual core ratios, or synchronize all cores at the same time.
497

Internal PLL Overvoltage. You can set this to enable to allow some additional overclocking headroom. Note that once you enable this function your sleep and hibernate will be disabled. With overvoltage enabled, most users should see their 2500k and 2600k hit 4.7-5.0ghz.
498

memory frequency shows you a list of frequencies.
499

Or you can set your Dram timings manually
500

GPU post / Dimm post shows you real time GPU lane configurations. You can see in real time what speeds your pci-e lanes are running at. No need to bug others whether or not you have the best configuration possible, figure it out yourself! haha Dimm post gives you real time memory frequencies.
501

In the CPU Ratio you can set this as auto or define the ratio for all cores.
502

Digi+VRM options
503

504

Load line calibration will stabilize CPU voltage under load. It will try and compensate for the Vdroop or drop in voltage that occurs.

I have detailed our recommendations to maximize the overclocking potential / scaling on ASUS’ P67 series of motherboards. This Guide has been developed after extensive internal testing across multiple boards, multiple bios builds and a high sampling rate of both D1 and D2 CPUs. While this guide is not a definitive article listing every possible overclocking combination, the information contained listed is providing repeatable results in our testing. Of course the quality of the cpu and cooling is very important but overall we think the results on our boards should exceed those of others at like settings.

Expectations regarding K series overclocking in general and on ASUS P67 motherboardsPrior to the recommendations on overclocking the K series, I am outlining our results to set expectations.
The results below are based on the range of the CPU turbo multiplier when overclocking.
Results are representative of 100 D2 CPUs that were binned and tested for stability under load; these results will most likely represent retail CPUs.
1. Approximately 50% of CPUs can go up to 4.4~4.5 GHz
2. Approximately 40% of CPUs can go up to 4.6~4.7 GHz
3. Approximately 10% of CPUs can go up to 4.8~5 GHz (50+ multipliers are about 2% of this group)
Additionally it is recommended to keep 「C1E」and「EIST」option enabled for the best overclock scaling. This is different than previous Intel overclocking expectations where the best scaling was with disabled power states or power management options.
Update specific to D2 and retail parts: Jan 11 2001
As always ASUS strives to be at the forefront of performance and functionality offered by a quality bios. Keeping this in mind ASUS has been actively working in conjunction with Intel to optimize overclocking potential on ASUS P8P67 motherboards and K series CPUs. With the latest bios revisions ( 1000 series ) or 600 series for ROG specific optimizations have been made to the microcode and corresponding tables that relate to D2 and retail parts. These are improvement are in addition to general improvements in all respects. Present with this new build of the UEFI is a new option. This option / value is “ Intel PPL Overvoltage” this option furthers multiplier scaling considerably.* In addition due to the increase in scaling more exotic forms of cooling cannot be used and will be needed under certain multiplier ranges and corresponding voltages. The general maximum range for the highest performing dual fan air based heastinks still remains 50x to 52x.

* Intel PPL Overvoltage ( for increased K series overclocking set to enabled )

Overall in our ongoing internal tests the maximum frequency now achievable ( under LN2 ) is 5.8GHz. At this time we do not have a compiled database to reference improvements in the overall scaling range or new % of CPUs able to hit 50+ multis. With that noted currently we are seeing generally a minimum of 2 multi to as much as 7 multi increases with this value enabled on applicable D2 and retail parts.
Example
A D2 sample with peak multiplier of 44 with PPL option enabled and corresponding voltage applied we have seen results of a stable 50 multiplier now able to post / boot and be held. ( previously without the PLL value the same CPU would failed to compelte a boot with a any multi exceeding 45 )
In addition to the increase of the multiplier range a “side effect” is additional Vcore needed to compensate for maintained post/boot and stability tests. The new voltage level do not align with standard voltage scaling ( on CPU already able to hit / sustain comparable multipliers.
Example
Generally 4.8GHz stability can be achieved at 1.400 – 1.425 Vcore now with PLL enabled D2 parts exceeding their previous max multiplier the increase in voltage would be 1.425 – 1.450.
It is important to note this option should generally only be used with D2 and retail parts NOT D1 parts. Internally we have partial results to indicate degradation of stability at previously reached multiplier values. Some internal testing has shown on limited samples that some improvement is possible (generally in the range of 1 multi possibly 2 )
In addition continued testing with the PPL option enabled and D2 or retail parts have shown some benefits to CStates being disabled when approaching, at or exceeding a 50x multiplier. An important note to keep in mind is that disabling CStates can considerably affect HD performance ( especially SATA6G ) Please keep this in mind when going for the highest level overclocks.



Expectations regarding K series overclocking implementation options on ASUS motherboards – Using Speedstep or Not Using Speedstep

Quick Note on implementation of K series Turbo Multiplier control –
While our Digi+ VRM option has extensive adjustments to voltages, multipliers and Bclk (such as .1 increments ex 106.8 or 108.1) one specific difference is noted below.
With the latest bios revision ASUS motherboards have a high level of flexibility at customizing the efficiency and consistency of the overclock values set in the UEFI.
It possible to overclock while keeping speedstep enabled and use the offset voltage method for Vcore increase this will provide the overall best in temperature and heatsink performance as well as generally efficiency and extension of the lifespan of the motherboards its components and the CPU. This is due to the Turbo Multiplier working and exucting ramping as Intel intended.
Example leaving all CStates and Speedstep enabled will allow the CPU to idle down in Vcore and frequency ( 1600MHz ) and ramp up when under load to 4.8GHz when needed.
Should there be interest in consistently maintain a desired clock frequency users can disable Speedstep and still keep Intel Turbo multiplier overclocking enabled.
• Please note that overall disabling or adjustments of Speedstep or CStates do not affect overclocking range ( this is different than previous generations when power saving states were advised to be disabled when exceeding 3.8 to 4.0GHz ).


K series overclocking benefits on different ASUS P67 motherboards

Quick Note Regarding Motherboard Stack – What does going higher in the board stack provide overclocking wise?
ASUS’ entire line of P67 motherboards features a class leading and high performance Digi+ VRM implementation that allows for superior overclocking performance; there will be differences between boards.
While our entire board lineup has been internally tested to fully support K series processors, when overclocking in multiplier ranges of 50 to 54x the higher end boards will benefit in two key categories.
1. Better Vdroop efficiency.
2. The ability to help drive and sustain a 50+ high load Overclock under maximum loads. Examples of boards that focus on this level are our Deluxe, WS, SABERTOOTH, and Maximus IV Extreme

K series overclocking multipier wall

Quick Note regarding the K series multiplier wall – Previous generations of Intel CPUs due to architectural differences had two aspects that could readily change OC scaling potential. These two factors were TDP (heat output under load) as well as core (CPU/VTT ) voltage being supplied. With previous generation cpus, improvements such as high end air cooling, water cooling or more extreme forms like LN2 in addition to extreme voltage increases could potentially provide increases in clock speeds on a continual ramp until the limits of the CPU were reached. This is not the case with K series on the P67 chipset.
In internal testing we have found that maximum multipliers in excess of 50 (up to 54) have been able to be realized with full stability under Air Cooling and with cpu vid voltages under 1.525V. In fact, the processors will actually start to downclock as they get colder with temperatures under -20C actually performing worse than the retail air cooler at times. The processors optimal range for performance is around 15~20C in our testing.
An example is noted below.
Should you have a CPU in hand that reaches a 47 multi easily ( posting/booting and running full stability tests at a set Vcore of 1.375V) you would then attempt to jump to the next multiplier. With the K series CPUs you may have reached the max multi regardless of the cooling or voltage used. Adjustments to either of these settings will not change the ability of the board and CPU to post at 48x. The only time it will continue to scale would be if the CPU in hand supports higher multipliers or can be finely tweaked to reach that next multi, in this case we suggest using the 47x multi and adjusting Bclk until you reach the limits of stability.
100BCLK + 47 Turbo Multiplier with Vcore of 1.375 and LLC ( load line calibration of ultra high = 4.7GHz
100BCLK + 48 Turbo Multiplier with Vcore of 1.400 and LLC ( load line calibration of ultra high ) = no boot
100BCLK + 48 Turbo Multiplier with Vcore of 1.425 and LLC ( load line calibration of ultra high ) = no boot
100BCLK + 48 Turbo Multiplier with Vcore of 1.450 and LLC ( load line calibration of ultra high ) = no boot
It is important to note that a post will still occur with a multi present that is at the multi wall. This is because only when the OS begins to initialize and the Turbo ratio is initialized ( kicks in and ramps up ) that Turbo Multiplier will be raised to defined multi at this point it will then cease to boot due to the multiplier wall being reached.

K series overclocking and voltage range recommendations

Quick Note regarding Voltage Scaling – Internal binning of both D1 and D2 parts we discovered consistent voltage scaling patterns.
1. For K series parts, the stock voltage supplied will allow for consistent overclocking generally up to a multiplier of 43x. There is potential for the multi to be raised to 44x depending on the load induced. This default voltage range be approx 1.240 to 1.260 under load.
2. Increased range between 44 to 47x multipliers will generally require a voltage range between 1.30 to 1.375V with an LLC recommended setting of high to ultra high.
3. Increasing the range between 48 to 50x multiplier will generally require a voltage range between 1.40 to 1.500 with a LLC recommended setting of ultra high.
4. Increased range between 50 to 52 (52 generally considered peak max multiplier except for rare 54x parts) will generally require a CPU voltage range between 1.515 to 1.535V with LLC at Ultra High and potential fine adjustments to the CPU skew range.

Overall a key item to note is the best voltage to oc scaling range potential for the turbo multiplier is 1.400 to 1.425 vcore. Using this voltage range with an LLC recommendation of ultra high will generally provide the best scaling potential with proper load temperatures*. We have generally found exceeding this voltage will not provide additional scaling or will increase load temperatures to a high level with synthetic load applications ( like Prime, Linx, OCCT ). Should you use more realistic loading testing (our recommendation is a combination of AIDA64 stress test, PC Mark Vantage) then temperatures under will be considerably under the max TDP rating.

*cooling recommendation and test performed with CoolerMaster Hyper 212+ with Single Fan, this is the minimum recommendation for multis above 46x. For 50+ multis we recommend a dual fan configuration with this cooler or improved cooling.
K series overclocking benefits from non CPU Voltage based adjustments ( UEFI values for power management , Cstates, PCH etc )

Quick note regarding bios values that should be adjusted

– Over a long test and tune cycle, ASUS has developed a class leading bios with superior auto overclocking. This superior performance translates to overclocking in two ways, manually or automatically via the use of our Auto Tuning application.
Keeping in mind that most retail K series parts will be sub 50 multi capable, our Auto Tuning application has been designed to Auto Tune up to a range of 50 should the CPU support it. In effect reaching the absolute maximum clock a user can reach manually. Additionally Auto Tuning can serve as a good option for seeing the potential in the CPU and max multiplier it may have before fine tuning the system.
An example is shown below. P8P67 (Standard) – 2600K, Hyper 212+, Corsair 1600C8 memory 4 dimm.

Should you continue with manual overclocking, these are the advised recommended values.

4.7GHz or Below
All bios values to Auto except for those noted-
CPU Turbo Multiplier
Dram Voltage to specification
Internal testing has shown Auto Values will allow for stability in all forms of testing including high synthetic high load applications (Linx, Prime95, Occt ). In the event general stability is not achieved in these synthetic high load applications, you can adjust the noted values for improved stability.
Digi + VRM options
VRM frequency to 350 – Requires setting to manual adjustment and entering the specified value.
4.7GHz and above
CPU Turbo Multiplier – To desired value
Dram Voltage to specification
Digi + VRM options
VRM Frequency change to 350 – this value will allow for scaling to 50+ multi without issues
Phase Control change to extreme – this value will allow for scaling to 50+ multi without issues
Duty Control change to extreme - this value will for scaling to 50+ multi without issues.
No other values need to be changed. Unless otherwise noted all other UEFI values used are AUTO.
K series overclocking and its affect on subsystem performance especially HD performance
Quick note regarding options that can affect subsystem performance
It is NOT advised to make adjustments to Cstates as this can considerably affect hard drive throughput performance ( especially SATA6G SSD or Sandforce 2 based SSD ). It is recommended that all CPU power configuration states be left on their default parameters. Overclocking tests have shown internally no increase in multiplier scaling when adjusting these values. * under special cases with high multi capable CPUs and synthetic high load applications ( Linx, Prime, Occt ) it may required C states to be disabled. This has generally only been confirmed for some 51-54 multi capable CPU’s.
K series overclocking benefits from adjustments to Digi+ VRM options
Advanced Digi+ VRM options recommendations
VCCSA
This has shown in internal testing not to improve overclocking, yet may still maintain the same level of stability while being lowered from its default value in order to keep the CPU cooler.
VCCIO
The adjustment of this voltage may help to slightly improve the overclocking capability of the IMC / DRAM, even though the default voltage is enough to run at a 2133MHz DRAM frequency. A 1.20v setting is more than adequate to maximize Memory overclocks in most cases.
CPU PLL
This setting did not improve overclocking, yet the user can maintain the same level of stability while lowering its default value in order to keep the CPU cooler.
PCH Voltage
This setting did not improve overclocking, yet the user can maintain the same level of stability while lowering its default value in order to keep the CPU/PCH cooler.
PCH PLL
This setting did not improve overclocking, yet the user can maintain the same level of stability while lowering its default value in order to keep the CPU/PCH cooler.
K series overclocking and how BCLK is affected and how to best optimize BCLK scaling
Quick Note for BCLK tuning
BCLK clocking is considerably reduced with this new CPU architecture and as such it is recommended to focus on Turbo Multiplier adjustments for overclocking. With that noted should you choose to make adjustments to the BCLK, ASUS has enabled extensive control to maximizing scaling.
Internal testing shows BCLK ranges from 102 to 109.1 with the largest level of scaling dependency placed on the quality of the CPU. CPU Frequency and speed is also directly tied to BCLK scaling. Internally we know that BCLK tuning largely depends on the CPU with approximately but we have noticed up to a 20% dependency on scaling potential based on the board design and PWM utilized.

At 4.9GHz, generally the maximum clock speed will not change with a different combination of multi and bclk in this particular example.
Example-
100x49 = 4.9GHz
103x48 = 4.9xxGHz
Generally the CPU will not do much more than what your maximum CPU multiplier range is in most cases. Keeping this in mind, we offer very fine adjustments down to 0.1x increments to allow for the maximum BCLK tuning.

Lastly when considering adjustments to the BLCK range, it is important to remember it will affect the memory divider/strap and DRAM frequency. Keeping this in mind you may want to adjust to a lower divider if your memory does not higher frequencies. This especially true when attempting to sustain 4 dimm and high memory density configurations with high BCLK and high Turbo Multiplier values.

Additional Information for a quick OC guide.

Assuming you have a CPU that can execute and hold a 48-50 multi the screen behold will show you how to quickly enable a 4.8GHz-5.0Ghz OC. Note that not all CPU will hit above 4.8 but there are quite a few out there. Remember to read the text and not the photos as it may have some wrong information. Ill try and get some new screenshots.

1. Select Ai Overclock Tuner,Select Manual
http://www.asusrog.com/forums/attachment.php?attachmentid=498&d=1304036088

2. Now see the expanded options for Turbo Ratio Control and select by number of active cores mode (Unadjustable in OS) this means it will be locked. Select By All Cores in OS means you can adjust it via aisuiteII.
http://www.asusrog.com/forums/attachment.php?attachmentid=497&d=1304036072

3. Now manually defined 48 value in each of the core values ( 1 , 2 ,3, 4 ). Later you can even try 49, 50, or until you hit a wall.
4. Set your internal PLL to "Enabled" Depending on what your retail CPU is capable of ( which Auto Tuning should provide you an idea of ) Enable this option! This option is specifically designed for D2/Retail Parts and allowing for higher multi overclocks especially when at or exceeding 48x. Additionally this option can be used should you not have it enabled and generally cannot boot with a higher multiplier. It is advised to try this option after you have tried all other standard options. This option is not for increasing stability of a OC that can already post and boot into an OS.
http://www.asusrog.com/forums/attachment.php?attachmentid=498&d=1304036088


5. Select Loadline Calibration,Select 75% which is suitable for our target of 4.8-5.0. This value will provide overall the closest load level of voltage to the value defined in the bios or AiSuite II
http://www.asusrog.com/forums/attachment.php?attachmentid=505&d=1304036151

6. VRM Fixed frequency mode; enter a value of "350". This is best for sustaining stability at multis of 48x or above. This is key especially for running unrealistic loading testing such as prime or linx.
7. VCore Phase Control enabled Extreme this ensures the highest level of current and overall power delivery for the board under heavy loading.
8. Ensures the Digi+ VRM managment system ( Vcore PWM Mode) is balancing for the most power possible ( current as opposed to temperature ) generally only for 48x multi overclocks or above. If you're overclocked 4.8Ghz and above you should set this to extreme. Anything below 4.8Ghz T.Probe is fine

http://www.asusrog.com/forums/attachment.php?attachmentid=506&d=1304036159

9. Select Manual CPU Voltage - This will allow for a consistent voltage to fed to the CPU to ensure stability. Keep in mind that should you want the most efficient overclock you will want to use offset as this will allow the voltage to track the VRD of the CPU and have the voltage fall and rise depending on the loading state of the CPU.
10. Enter a CPU manual Voltage ( Vcore ) value of 1.415 or 1.425

Use a FAT 32 formatted flash drive.

[jermzz]

Great guide, I've got my 2600k D2 at 48. One problem though.. And it does this at 4.5 and 4.6 also when I was OCing before reading this. I get BSOD'd when I run prime after 30 min or so, it passes the small packet test a few times before it happens. Could this be a ram problem or something? the temps are high but within range at 4.8. 77 - 78c full load. Any idea what would cause this? It's quite annoying. I was at 1.425 vCore, I just upped it to 1.430 and im trying again, but the fact that it's happened at multiple lower OC's yet still manages to boot and run Prime for 30 min makes me curious...

EDIT:
Fwiw, im running an a70, and on the factory boxed BIOS.

[Steven_belfast]

Folks just ordered one of this mobo's
What is the best way to update the bios?

[xeromist]

Format a USB flash drive using FAT32 and then put the BIOS image on it. Boot into the BIOS and use the update function there. There are other ways but this is the most reliable method.

[Steven_belfast]

Greetings xeromist
Thanks for the reply
Is that in the bios its self or using the usb port and holding the rog connect button for 5 seconds?

Ps: i was going to go for bios 1409 do i need to remain the file at all seen some saying it had to be M4E

[Area 66]

it's in the BIOS , you go in tools section and you choose Asus EZ flash 2 utility

[Steven_belfast]

Thanks folks the help has been great.
Been busting to get my new pc and i managed to get it ordered today so over the moon.

Ok folks another quick question.
Where i live i cant use ethernet and am not able to use home plug adapters,
So i have to use wireless (what a let down) but its gotta be.

i have ordered a 300Mbps wireless pcie card.
Am i able to use this with out it slowing the Gpu down?
If so whats the best slot for the Gpu and wireless card?

Ok forget this post was daft and a lack of sleep

Did you manually set the dram voltage to 1.65v?
Also you should check your latencies. Maybe a -cas 9(or 10) / ras to cas 11 / ras pre 9(or 10) / ras act 27- comb would go fine, under dram timing control section. Cheers.

for the EVGA u have to use MSI AFTERBURNER, u can get it here
http://downloads.guru3d.com/-MSI-Aft...load-2740.html
thanks to guru3d

will say it will expire soon, but dont worry new beta is due tu this days...

u have to go to settings and UNLOCK volt control and volt monitoring ;)

u'll be fine with this

r u on SLI ? if so use PCIe SLOTS 1 & 3 native mode rocks ;)

It is NOT advised to make adjustments to Cstates as this can considerably affect hard drive throughput performance ( especially SATA6G SSD or Sandforce 2 based SSD ). It is recommended that all CPU power configuration states be left on their default parameters.

The above part of the guide...
What are considered as defaults for the CStates?

what volts are u using ? u can unlcock them to 1,21 volts as you are on water not a problem ;)

Hi Folks,

System going well now,
Just one ( i bet this is going to be doppy ) Where in the bios can i stop shaired memory to the graphics card ?
I am running a Ati 6990 and windows is giving it another 3.8 Gig of memory lol.

[Steven_belfast]

what was the problem ?

After checking ever thing, ram, sata data and so on i removed the mini display to dvi and just connected to the dvi port and it worked ok,
Ok it might not be that but i checked every thing else and only worked after i changed this.

Ps: when i was getting the error i was not getting any thing on screen.

Steven

windows is showing 3.8 and some GB saying shared on SYSTEM in CONTROL PANEL right ? instead of 4GB ?

if its so...just follow this steps

1) put the win7 DVD and start
2) hit repair boot
3) let it go and repair

it will fix that for ya, for ex if you type msconfig, and asign 8 cores and ALL mem to the windows start win will re arrange things and will put that sort of stuff

if you go to control panel - system . win should say installed ram 4GB / 8GB / etc not less

cheers good luck

Hey guys, Ive been having some USB Issues and wondering if someone can help, how should i setup my USB settings in BIOS, should i use NEC or PCH and also i hear u need to connect the 4 pin molex on the Motherboard which i haven't currently but i did connect 8 PIN on top of the board next to the CPU, doesn't that do the same thing?
Also 1 more question, i currently running everything on stock and my 2600K is running at stock 3.4ghz speed and my ram at 2133, RealTemp shows my Temps as follow"
Idle: 35 35 34 34
Playing games: 41 42 39 39
My room temperature is around 78F, can u guys let me know if those temps are ok?

Hi, you should start your own tread, aside it's not the good place for it, this tread is suposed to be a guide for OC the board.

Msi afterburner 2.1 only allow me to 1.1 voltage ...

[bullydog]

Hi everyone glad to see so much information available for this board! Is the BIOS 1409 posted here applicable to Maximus Extreme-z68 ?? I just downloaded and flashed my BIOS to the latest one from Asus support side and it is 0403
Sorry if this has been mentioned somewhere...

[bignick]

i need help understand why my iphone iconnect it s working with my g.skill 4x2 1866 ..but not with the mishkin 2133 ( i can run OC but hardware monitor give me an error ) ....also if i run the mushkin at 1866 iconnect is working
thanks ..i really need to understand why

[xeromist]

It sounds like the Mushkin is unstable at 2133. Have you run any benchmarks/stress tests to confirm system stability? Also what is the size and number of Mushkin DIMMs?

[bignick]

Mushkin Enhanced red line pc3 17000 ddr3 2133
9-11-10-28 @ 1.65 v
I run wimdows memtest and no error ... Also play crysis 2 with cpu oc at 5.0 and 2 gtx 570 oc @ 910 with mo problems

[xeromist]

Which USB port did you connect it to? If you have it connected to the USB 3.0 port you should try one of the 2.0 ports to see if that works better.

[bignick]

I m actually connect wifi .... I think i still have bios 1305 .. Maybe i need to update it ...
Thanks

[xeromist]

OK, perhaps I'm missing something. Isn't the iConnect a keyboard with an iPhone dock? Does that connect by WiFi?

[andressergio]

not at all mate i have same kit and run awesome at 5GHz HT 2133 9-11-10-28 1T

[bignick]

Iconnect is a app for iphone to connect ( usb , wifi , bluetooth) with the asus maxus iv extreme and check temp overclock from your iphone .... I can overclock but since i use the mushkin memory i canmot check the temp and voltage with it ... Maybe is my old bios ...

grats on that man, use BC2 to test for stability if you dont wanna use prime

i only bench above 5GHz, i have 2 x56 chips and i disable 2 cores and HT and use less than 1,6 to bench them

i will test 5.2 4/8 for ya and let you know

what is HT ?
Hyper-Threading

[andressergio]

what is HT ?

as the buddy here says HT is Hyper Threading technology wich is a design that simulates virtual cores by an implentation on the queue of proccessing u can say that its like if you have a supermarket with 2 checkputs you open another one and everything will go faster ;)

this time on SB HT works as it should, on the 1366 was not so good

ASUS you need to move your ass and bring out a new BIOS with Elpida Hyper MGH-E suport.

Its not acceptable to pay 300€ for a MOBO Extreme that doesnt suport 100% Elpida Hypers ICs.

I have some Corsair CMG6GX3M3A2000C8, the problem is my sistem Freeze when i try to run some Super Pi 2M or above 2M.

It's not acceptable, you need to fix this.

Waiting for an answer frome someone at Asus BIOS department.

EDIT: I forget to say, the problem start at 1866 strap, and 2133.

[psyside]

Hello Raja/Brian, can i take in account the explanation of each setting from Gene-z and set it to maximus extreme iv BIOS as well? (because its more recent updated guide) i think this boards are similar enough to use that guide as well.

Some more info please,

Many users saying that i should use spread spectrum, many say dont use it, i'm at 5.0ghz atm, 1.425 vcore, Vccio @ auto, CPU PLL is 1.55 (i get quite lower temps with this lowered from default 1.8) Dram is 1.55, vcore switching ferq is 350, vcore over current protection is 130%, VCCIO full phase control, Dram full phase control, VCCSA full phase control are all on.

This are the main settings and i need few answers about some values regarding my BIOS settings/OC

So please tell me what to set in the next options,

Spread spectrum - enable/disable?

Turbo mode parameters settings? disable/enable? i never understand the settings about Turbo parameters in the BIOS, AMP/Power etc, neither someone answered me about them, im affraid i can burn out my cpu buy putting to much power into if i dont know what to use ragarding this options so i dont use them, not before i know what exactly they do.

Intel adaptive thermal monitor - enable/disable?

Vdram switching ferq - 1x vs 1.4x?

Vccio switching ferq - 1x vs 1.65x?

Vccsa switching ferq - 1x vs 1.65x?

over current protection for this 3 valuse as well , enabled vs disabled?

Package c state limit - enable/disable?

CPU C1, CPU C3, CPU C6 - enable/disable/auto?

CPU ratio - auto vs maual?

And for the end something not related to overclocking. USB 2.0 switch, NEC vs PCH.

Please, answer because im looking for the answer of this settings long time.... thanks!

Nothing we can do. The memory sampling uCode is controlled by Intel not us. Further, some IMCs are better than others and some boards work better than others due to differences in trace impedance/capacitance. That's all there is to it.

If there are any voltage table changes or others the OC profile from an older build will cause issues so we force a reset.

Read the UEFI guides in the forums for explanations of most stuff. Increase some of the OCP thresholds. 5GHz is a tall order for some CPUs.

Hey all,

Awesome guide here and some very useful information! Thank you so much Brian and Raja.

So far using the guide ive managed a rather conservative first attempt of 4.7GHZ at 3.80v in the bios and its stable too, been running aida64 stress, pcmark loops and also intel burntest just to see how hot it gets! So far using this board has been a pleasure compared to others I have over-clocked with in the past, it just keeps posting!

Seeing Andressergio's results i think i may have to spend some more time soon and see how far i can go ;).

I have a question for you guys regarding Vcore (my first sandybridge over-clock). You stated in the guide that 1.4-1.425 seams to be the "sweet spot" and going any higher would just cause more harm than increase speed further. Would you consider this voltage range up to the 1.425v safe for long term usage? Providing the CPU is kept cool? I am on water cooling currently, and my current load temperatures using intel burn test are 60-62c TOPS after a good half hour of stress.

Im basically going to slowly see now how far my 2600k will go, and Id just like to have a set max "sensible" voltage to stop at while im doing this as my aim will be the highest stable clock i can run with 24/7. This is when i remembered your stated 1.4-1.425v sweet spot.

Many thanks, If any more information is needed when it comes to helping me push further I can provide it and or start a new thread as not to crowd this one, but so far im doing pretty good, no hiccups or walls yet!

Hope you guys don't mind helping me out as im exploring my maximums! :D

thanks General

u can go as far as 1,45 LOADED IF temps are good you dont need to shoot your system PRIME or BLEND to blast it, just tune it and use BC2 as guide, if your OC passes 1hour gamming at max settings its ok ;)

problem starts when ppl (i respect all those who blend 9 hours and 2 hours linx) but from my personal tests i BSOD while playing some games even passed LINX and PRIME so...gamming heavy the real stress

good luck from here
Sergio

[TheGeneral]

Oh well that's good to hear!

I've never been one to let prime run all night to be honest (id never sleep in-case it caught fire! lol!), as long as games and apps don't crash as you say that's fine by me lol! Ill dial it in for 1.4 ~ 1.425 and see how far i can go using some crysis 2 and arma 2 hehe.

Do you think the in-game bench's for these will be a good thing to loop for a while? if they are good for an hour ill start to play myself :D

Thanks for the infos

*Edit*

Also, would this be with 75% or 100% LLC? I tend to run without speed-step as it can mess with some app's in my experience, so should I be wary of the overshoot? would the max be 1.45v including the little overshoot?

Or would you recommend going with speed step and or voltage offsets to be safe?

Again thx for any infos guys, these sandybridges are a whole new animal to my i7-950 hehe :D

*Also*

Have to ask Andressario! How did you get two task bars one at the top and one at the bottom? AND Whats that cool gadget'y'mybob you have on your right of the screen? :D

i would not use offset ma mate, it needs more time than put a normal manual vcore, yes use 75% LLC and VRM 350. also try PLL om 1.7 and enable EIST and C1E

the taskbar on the top its free its Stardock Object Dock u can get here

http://www.stardock.com/products/objectdock/

the gadget to the left its

XDSystemA1.gadget u can google it easy to find

cheers !

[TheGeneral]

Awesome thanks a lot Sergio!

Will try this today!

One last question, was there anything else you changed in your Digi+ menus? Any chance of a screenshot?

Im at 4.8ghz right now with 1.425v in the bios (can probably go lower havent tried yet, just seeing how high a multi i can get on it.) It ran through crysis 2 benchmarks and PCmark Vantage all night so looks stable enough to me!

I was able to boot into windows at 5GHz, but it needed 1.45v in the bios and wasnt quite so stable. Didnt want to use any more Vcore than that, so any idias on what else I could try to make it work?

Many thanks again friend :)

no problem friend

yeah i have 75% LLC and VRM 350 nothing more

remember no chip are equal, so maybe our batch needs a bump on vcore

cheers and good luck
Sergio

[TheGeneral]

Awesome thanks! :)

Will let you guys know how I get along!

*Update*

Well had a good go at it!

But looks like what i already got (4.8GHz @ 1.425v) is going to be the best i can do for long term usage, still pleased with that though! :)

In order to boot at 4.9Ghz i need at least 1.44v and 5Ghz needed over 1.45 (like 1.46-1.47) so i didn't think it was worth it for ~100-200 Mhz hehe, would only be hurting it over time i guess.

Thanks for the ideas anyway! guess I just got given an "average" chip :P

Hi guys...Is there any way to give more than 1.80 vdimm when benching? 1902,1409,1850 bioses are used...
Thnx

How to set iGPU to run at 3000MHz?
iGPU offset voltage? +/-?
on auto I can do up to 2150MHz only, 2200 will hang/driver lost during video transcoding..

[Sir_Chris]

Hi guys. I clicked the Auto Tuner and set it to "Fast" and after my system reboot it said it went up by 30% but when I check my CPU is still at 3.4Ghz.I think it upped my Volts from 1.25 or something. So..did it work?

i7 2600k
1.304V

Thanks!

[Alek]

Hello.

So, what u need to know bout me is this: i'm maniacal ! :D
There isnt any reason on this planet could convince me to keep a bad overclock.

I'm just switching to asus maximus IV estream-z and 2600k.. and i'm not reallu appreciate the change.

I can't even figure myself why i should keep a 1,344 idle voltage for a 1,288 full load one... (and that was just for 45x).

So i start try offset.... and,yes, it looks like LOT better.


i Just wondering: i read a 3d on this forum where opener Says: "WE SUGGEST U8 TO SET LOAD LONE CALIBRATION AT 75% IF U WANNA USE OFFSET" ... BUT i got my best results using 50% (high)....


Offcourse this is only a testing multipier.. my target is 4,8..... but i just wondering to show u what i'm talkinjg about:


http://s1.postimage.org/8ieuuxg8e/44x_class_50.jpg



And idle voltage:

http://s1.postimage.org/c21943zxo/idle_44x_50_llc.jpg


Now... with llc setting to 75% (ultra hight) i need like 1,312 full vcore toi be stable.,.....(idle is almost the same).

So, why should i use ultra?

I just wondering why before start "serious" tests!!

Thx and have all a good .. well doonnow here is night.. but for u could be be day :)

Hi forum

Will there be a bios update so we can use the next gen cpu 3700k

[Akarim47]

thanks for the guide, I did everything you recommended but I kept getting blue screen crashes. the thing is when I decided to to go back to default setting for now. I went to the BIOS and pressed f5 to load the default settings. booted to windows and the cpu speed was 3.8 and the computer wouldn't go the idle speed 1600 like it used to, any idea?

my system
Asus Maximus IV Extreme Z
Intel Core i7 2600k D2
Corsair Hydro Series H100
MSI N570GTX Twin Frozr III
Corsair 4x4 GB Vengeance PC3-12800 1600mhz CMZ8GX3M2A1600C8R
Corsair AX850

never mind, I turd off the computer, unplugged the power and plugged it again and now it's working fine.

[jewie27]

I have auto-tuned my 2500K to 4.7Ghz :) Very happy with this Maximus IV Extreme-Z.

[junC]

I have a maximus 4 Extreme-Z motherboard.
Now I have a problem with setting the memory frequency to 2133
I've tried raising the VCCIO voltage to 1.2V and i enabled XMP profile.
Does anyone have any suggestions on how to set memory to work at frequency 2133?
Memory is http://www.gskill.com/products.php?index=397

[8 Pack]

VCCIO for that memory at stock is 1.25 as far as I am aware. You have the voltage to the RAM at 1.65v???

[junC]

Yes I tried to set VCCio to 1.3V and the memory voltage I set to 1.65V and it, did not help :(

[jhuk]

VCCIO should be set by default to 0.5v lower than DRAM voltage!

That is why both DRAM Voltage @ 1.65v and VCCIO @ 1.15 are last settings before fonts in Bios turn a new colour to warn you of limits!

That RAM @1.5v should only need VCCIO @ 1.0v (1.5v-0.5v=1.0v)!

[Mack 4033]

Very good my chip will oc to 5.0 Ghz

Thanks,

[LuNaTiC]

As fresh with Intel rig (was lot of time an AMD user) i just followd up the overclock guide

I put everything as guide says except vcore that i put 1.400

I did some Prime95 + Linx testing and so far i notice the max temps are
Core 0 62
Core 1 72
Core 2 69
Core 3 67

Package 74

First question is my temps OK?
Second question i notice that my Vcore is STABLE at 1.400 even when Cpu lowers frequency to 1605mhz is that normal? or i miss any setting? If its meant to work like that what setting i must fix to drop down vcore when my computer dont have any serious load job to do ?

My system is
Intel 2600K Model A Stepping 7 Ext.Model 2A Revision D2 according Cpu-z
Maximus IV Extreme-Z Latest Bios 1409? Mobo
Corsair Force GT 90gb SSD
2x Western Digital Black Caviar 640gb HDD
Sapphire 6950 2gb GPU
Corsair Vengeance 1600 9-9-9-24 16gb Ram
Corsair TX 750w PSU
Antec 1200 Case
Corsair H100 Cooling

Thanx in advance

[HiVizMan]

Temps are fine and within normal range.

VCore will stay at the setting manually entered in bios. Leave on auto or use offset if you wish to have a dynamic vcore.

[LuNaTiC]

So what you suggest me??
how is my temps?

[HiVizMan]

Temps are fine and within normal range.


As I said your temps are within the expected range. :)

[liberato87]

what about these voices into bios of asus maximus extreme-z?

- max power (enable-disable)
- long duration power limit
- long duration power maintaines
- short duration power limit
- additional turbo voltage

- cpu core current limit
- cpu i/o current limit

- package c-state limit
