Is this a Safe 24/7 Overclock - Maximus V Extreme i7/3770k

Shreve
Level 9
Hey guys,

Went ahead and did a small overclock

Raised Multiplier to 43, so the system is running at 4.3 ghz

Set the Core Voltage to manual at 1.200 - Flat. It doesnt fluctuate up or down (couldnt figure out the +/- offset stuff...
If I set it to auto the voltage was 1.256 flat which seemed high so I just lowered it to 1.2

Anyway, everything appears stable with Prime95 (1 hour run)

Prim Temps peaked at 70 degrees but mostly hovered in the mid to low 60s
Core Peaks - 64, 70, 70, 67

Idle Temps hover in the mid to high twenties. Occasionally moving into the low 30's

So how does this look? Am I running any major risks here? Is the 1.200 voltage too high to remain flat with?

Any help is always appreciated

My blessings also.
....But don't you want 4.5GHz and lower temperatures? Also don't you want, when in idle your chip to go down to 1600 and Vcore to 0.9?
Check the screens, apply the same settings and give it a try. You can also visit ROG EXchange and try settings from others or upload yours.
For memory use your XMP profile and ignore my settings for DRAM Voltage, IMC and VCCIO.
If any instability, change CPU offset to + and leave value to 0.005.
Have fun.

Thanks for the feedback guys!

nikosa43 - I will take a look at your settings and see if I can replicate

As far as your questions go... They are good questions and the answer to all of them would be "yes".

Currently with the way that I have it configured. The speed DOES fluctuate between 1.6 GHZ and 4.3 GHZ, but the voltage stays the same

It would be great if I could figure out how it would run at 1.2 volts at 4.3 (I know it works there and the temps arent bad) but then when the speed went down to 1.6 GHZ, the voltage would go down to 0.90 or something...

Anyway, again I will look at your settings and see if I can figure it out

Thanks for everyone's patience with the NOOB (Although this is my 4th pc that I've built since 2003 ha ha)

Not to hijack but I gave these settings a run and did not even make it into windows. 😞 Also my CPU never drops below 2.8Ghz even w/ all C-States and speed spectrum enabled. The only way I found to get my CPU to drop below 2.8Ghz is to Disable Ratio Sync Control.

Hi Wish2000, please post some info about your system and may I can help.

Hey Nikosa,

Here is the steps I take to get my CPU to throttle down to 1.6Ghz.

Step 1 - Clear Cmos
2 - Remove battery for 5 mins
3 - Load Fail Safe Defaults
4 - Save and Exit
5 - Enter bios again
6 - Change AI Overclock Tuner to X.M.P. and verifiy my memory is at 1866, 9,10,9,27 2T and 1.5v
7 - Save and Exit
8 - Once in Windows 7 open RealTemp v3.70 and or CPU-Z v1.63
9 - RealTemp and or CPU-Z will show my CPU is running at 3.8Ghz without stepping down to 1.6Ghz.

What I have found to fix my CPU so that it will throttle down to 1.6Ghz is to either use
1 - CPU Level Up at 4.2Ghz, Save and Exit. Re-enter the bios and change the Core Ratio Limits to 38. Then Save and Exit.
2 - Enable all C States and Enable CPU Spread Spectrum, Save and Exit the bios.
3 - Disable Ratio Syncronizing Control, Save and Exit bios.
4 - Or Load Optimized Defaults and let my memory run at 1333 9,9,9,24 1T 1.5v

You are doing well with steps 1-5. Repeat them and boot to OS.Verify that speedstep works and your CPU works 1600-3800, Vcore also has to step down.If you have installed Ai, and you don't want to uninstall, go to settings and disable DIGI and EVO. Sometimes whatever you change in BIOS don't work, because when you boot in OS Ai take over and apply manual voltage that disable speedstep.Next enter BIOS, load XMP, save, exit and reenter to verify timings and Voltage of RAM. BE sure that it gets the values given from SPD, save and exit.Boot in OS and verify speedstep works again.Run a quick run of Intel burn test to check stability and while there have an eye to CPUZ and write down Vcore under load.Reenter BIOS go to DIGI and set LLC to Regular and Mosfet frequency to Optimised. Save, exit, Reboot and run Intelburn test to check stability and from CPUZ that you have lower Vcore and lower temperatures. Also if with the above steps it doesn't throttle down, check your power plan in OS and set it to Balanced.Please post back the results.

Thank Nikosa,

It looks like setting my Power Plan in Windows 7 to "Balanced" solved my throttling and voltage problem! One last question, I did not see any setting in the bios for Mosfet Frequency under DIGI+ Power Control.

Congrats Wish2000, happy for you to worked it out. Mosfet Frequency is the setting CPU POWER PHASE CONTROL. Go there and set it to OPTIMISED. In Max V Formula by default this is set to Extreme, but for this clock (3.8GHz), it's not necessary to have this setting up that high. It adds heat and stress for no reason. It will be handy for later on, to higher clocks.So keep it there for the moment and verify that you are absolutely stable. Run Intel burn test (also at the highest settings) and anything else you usually use for verification and go to event viewer to see if you have any WHEA errors. If not, CPU and RAM are ok, so next stage is go for testing a higher clock. (but not from a profile).
