Can you be a bit more specific?

Was the problem there before or is that why you updated?

What are you calling a long time?

Check your settings for CSM and UEFI*

The Asus board takes longer than other boards to get to post.
I would like to see ASUS fix the problem concerning prolonged boot time when using a M.2 PCIe drive with a NVIDIA graphics card since NVIDIA made some research and told me that it might be as ASUS problem.
Any ASUS guys around?

Maximus IX Hero here. Boot times definitely taking longer on the new bios. Reconfigured all settings the same. No idea why.

Memory overclocking (and CPU in general) seems more stable. Pushed from 3200Mhz C16 to 3466Mhz C16 and it's stable where before it was ugly. Didn't even have to raise CPU vcore to hold it now. Nice.

I noticed my CPU minimum voltage was raised slightly on both my M-IX-H + 7700k boards. Mine used to idle at 0.672-688v while my other board idled at 0.720v. Now both boards idle at the same 0.704v now. Strange.

My Z270H board does not like new 0906 BIOS at all. If I shutdown my computer it will not POST until the unplug the PSU cable for a few seconds and start it again, then it boots normally. If I reboot from Windows it reboots fine, it is just cold boots or when returning from sleep it wont boot at all, just spins up the hard drives, does not even spin up CPU fans, the troubleshooting LEDs does not indicate anything.

Back to 0801 BIOS and everything is working fine again. (Also tried to reflash the BIOS 0906 again, but I can still reproduce the issue.)

The BIOS have been working great for me since it was released, my board works exactly the same as 0801.
The boot time is the same too.

03-27-2017, 09:48 AM
So far the 0801 has being good. i will wait for that update since all is ok. Regarding the the boards posting times, i see that. I will assume that boards take good steps that all is ok before post. I am not worry in that area. a part for the improvement, anyone see other fix or improvement? I am using 6700K and it has being ROCK SOLID.

I'm having strange issue with this new bios. My cpu is running at 800mhz when I select XMP profile for my memory kit. :confused: I tried booting without xmp profile and cpu worked fine.
When I'm using 0801 bios, everything is working with XMP profile and clock speeds are normal.

Anyone else having this problem??

I have a problem when I set the over clock to XMP and do not change anything other then memory settings it will post once at 3200 memory speed. Once I shutdown the machine it will no longer post. I having similar issue prior the BIOS update. Just was booting sometimes.

0906 also installed on M9H, no problems at all. XMP @ 3200 using GSkill 3200C16D-16GVK x2 = 32GB. Two 16 GB kits guess I got lucky. Board rock solid, passed Memtest for 12 hours with no errors, RealBench 4 hours stress test no problems.

I checked my VCCIO/System agent voltage with 0906 and they where way to high when using XMP, explains why it did not POST as I wrote above.
Booted back to 0801 to write down my auto values of VCCIO/System Agent Voltage when using XMP:

VCCIO Voltage 1.128
System Agent Voltage 1.216

Booted back to 0906 enabled XMP and manually configured:
VCCIO Voltage 1.15 (mb reads it as 1.128)
System Agent Voltage 1.2 (mb reads it as 1.216)

Now 0906 POST without problem with my Corsair Vengeance LPX 16GB CMK16GX4M2B3000C15, and seems as stable as it was on 0801.

Unfortunately I can conform this error with the new BIOS 0906 - STRIX Z270G GAMING. It is not working properly with XMP settings. When loading Windows with XMP enabled the Computer just freezes at Windows loading screen and I must reboot. Interestingly, it passes the internal memory test at post. With XMP disabled the Computer is loading Windows properly but it feels slower than usual.

I had no such issues before. Everything was working fine under BIOS rev 0701 and 0801. I did not take a look at the System Agend and VCCIO voltages but instead went back to the old BIOS. Thanks to zorin1 & appe_ for already figuring out that the issue might be solvable there.

Hope this won't be a permanent matter in future BIOS updates. What do you guys think? Will Asus set this straight again with the next revision?

Can you explain more what you mean by "mb read it as ??" Are you saying that you entered the same value in the BIOS but when you log into Windows and run some program that is how you the different readings?

I had the exact same issue above. Getting into the bios was very difficult as the screen wouldn't power on 3 out of 4 times. Had to unplug the pc completely. Gone back to the 7 bios as I found 802 unstable at 4.9 ghz.

^ I have the same problem with Z270H and version 0906!

XMP on and it doesn't wake up from sleep and if u (force)turn the pc off it, it wont boot unless u do the psu cable trick..without xmp it works fine, but may I ask thee how do you return to previous bios version?

THIS WHOLE BUG NEEDS TO BE SOLVED ASAP!

I am having the same issue with my Maximus IX Hero since i got it. I created a topic in this forum about that.
It looks like the memory settings are causing this, since everything works fine with memory at 2933 Mhz (instead of 3600 Mhz).
A new pair of RAM sticks or the BIOS update to 0906 didn't solve the problem.
Still going with 2933Mhz and looking for a solution.

If it only happens when XMP is enabled, it's due to instability. This isn't a bug with the UEFI

Try tuning the SA and IO voltages. The voltage applied on Auto can change between builds due to some CPUs needing more. If your CPU prefers less than a given UEFI build applies on Auto, you simply need to tune it to the correct value.

Sorry, but I won't try tuning anything. The board and its chipset are made to house my 7700k and the used memory is feautured in the QVL for my mainboard on the ASUS support page. So as long as I'm not overclocking my CPU I expect the system and its memory to run with default XMP settings out of the box. And that was the case until 0906 was released. If the voltage applied on Auto changed with this most recent built to the point that it messes with the overall stability of my system, this is faulty and I dare calling it a bug.

Hello Raja
Is there any way to contact bios team about this issue? Maybe there is something wrong with 0906 bios? Or perhaps simple human error was made when updating the code? Have they tested this bios with for example ripjaws v memory which are in the qvl for z270g and probably for other z270 boards?
I personally have been hearing reports of similiar problems in other forums with high memory speed using xmp with z270 boards and common thing for all is that everything was fine with 0801 and earlier bioses. :confused:

I got my system working by manually adjusting vccsa and vccio to 1.15v on 0906. I haven't checked what it sets on default settings because I think if there is too much voltage or something with default settings it can do damage to my system, cpu was running 800mhz on desktop under load when using default settings and xmp profile.

Hi,

I can also confirm there is a problem with 0906, I have a Maximus ix Hero running a 7700k @ 5ghz and 32gb of G-skills Trident Z @ 3000mhz and its been rock solid and stable with every bios revision so far and passed all benchmarks and stability tests inc 8 hours of realbench and 8 hours of prime 95 v26.6 but that all changed the second I updated the bios to 0906. since then my memory is failing memtest unless I run it with 2 sticks of ram and not 4 and my overclock stable voltage is moving around, originally its always been at 1.35v but when I updated to 0906 suddenly the cpu needed 1.45v and then after a day it was wanting more voltage and became unstable again. while studying hw info I noticed random spikes and drops in the vcore voltage, the memory, system agent and vccio so I tried to stabilise it in the bios with absolutely zero success so last night before I went to bed I flashed my bios back to 0801, put back all my settings and overclock and then ran realbench while I slept and when I woke up its was happy as larry again and rock solid stable. I have since then ran 3 passes of memtest on all 4 sticks (32gb) with no errors or problems.
I think its safe to say that there's nothing wrong with anything I was doing and something very badly wrong with the coding of 0906.
I hope this info helps and if anybody disagrees with me then please don't shoot me!!!!!!

As Raja has already said, these rules change over the course of a platform life cycle, and stability from build to build should not be assumed. If the system is stable and you are not waiting for any further feature or compatibility implementation, then there is little reason to flash unless advised to.

What works for some users may not work for others, so if the rules have changed then they would have done so for a valid reason. Best to simply tune the system in manually and not think to much about these things :)

So bios updates are not used for increasing system stability and performance like majority of them are when it's mentioned? And complete support for optane memory for example is not good enough reason to update your motherboard bios?

When bios update causes instability for so many users then one would think that there is some kind of problem with the updated bios. I remember having gene v and all the bios versions were stable in that system, from beginning to very end. Even having 2400mhz memory on ddr3, even though there were some bioses with no performance and stability increase promised and not specially adviced. I still updated it every time and all was well... And I know that it was different system and my components may still be the issue now. :rolleyes:

The point is that there is so many of us with these problems. Im ok if my cpu or memory is the culprit, it's just hard to believe... :)

Unfortunately the scope can be huge when trying to cover each individual CPU (with regards to auto rules), and the nature of things means that manual tuning is often required. This isn't something that is exclusive to a particular board or platform. If wanting to outright avoid these situations, you can either stay on a build that works for you, or leave the memory at stock.

I investigated little more about this. Look at these voltages...

DEFAULT AUTOMATIC SETTINGS WITH XMP ON 0906
63588
DEFAULT AUTOMATIC SETTINGS WITH XMP ON 0801
63589

Id say there is something wrong between 0801 vs 0906 if VCCIO voltage is way over the top. Maybe so over the top that cpu cannot handle it and is running always at 800mhz? It seems that cpu standby voltage is also bumped in 0906 :confused:

And again, setting vccio and vccsa to 1.15v everything is fine.
Reads in bios:
VCCIO ~ 1.136v
VCCSA ~ 1.184v

Yes, that is very nice of you to point out. But if you revisit my comment again and more carefully, you will see that I mentioned the conformity of my system specs with this particular kind of overclocking according to the QVL. So this shouldn't matter and I still see the responsibility to assure general stability with ASUS by releasing proper BIOS revisions.

If wanting to outright avoid these situations, you can either stay on a build that works for you, or leave the memory at stock.

Again, my system and my implementation of the memory via XMP are in accordance with the QVL. I can't see any reason to simply swallow either the lack of features by staying with 0801 forever, running the memory at slower frequency or having to tinker with the voltages myself at this stage. I can understand that this is getting necessary at the latest when I overclock the CPU manually though.

Exactly. With BIOS version 08-- XMP worked perfectly, with 0906 it does not work at all. So the bug is indeed in 0906, at least for Z270H.

QVL doesn't ensure 100% compatibility, so there is no need for him to revisit your post. The vendor listings provide a list of kits that have been validated to work on the board to ensure the user the best possible chance, it's not a guarantee. In fact doing so across UEFI builds is almost impossible if trying to accommodate every possible configuration/sample.

The memory training routines and the multitude of conditions that need to be met means not all values will be valid for every individual case. If rules change, user intervention can be required. So when speaking about overclocking memory with higher frequencies, yes, it really does matter as these margins become tighter.

This guide here should help a little. It's not a topic that's easily digested, but it contains informative nuggets to better understand the requirements that need to be met at POST to the likes of laymen (including me). The take way really is that although unconditional compatibility would be fantastic, it's not a realistic outlook.

So as long as I'm not overclocking my CPU I expect the system and its memory to run with default XMP settings out of the box. And that was the case until 0906 was released. If the voltage applied on Auto changed with this most recent built to the point that it messes with the overall stability of my system, this is faulty and I dare calling it a bug.

edit: sorry for the salt, I know you just try to help out here.

Some water to dilute the salt: When it comes to memory, anything faster than Jedec (timings & frequency) is technically overclocking and results/needs will vary from part to part. Each set of components has a sweet spot, and as a system integrator (you), it's up to you to tune the system according to the capabilities of those parts. If you don't want to tune manually, you'll just have to run things as is.

Exactly. With BIOS version 08-- XMP worked perfectly, with 0906 it does not work at all. So the bug is indeed in 0906, at least for Z270H.

I agree with this. At least people here were kind enough to tell me what to set in the BIOS manually to get it to work.

Hello.

I've same issue on Z270G (7700K + Corsair LPX 3200MHz CL16). When XMP is enabled processor running only at 800MHz.

To offer a different point of view, XMP isn't functioning properly for me on 0801 (and didn't on the BIOS my board shipped with) so it isn't universal. I've had boot problems with XMP enabled since I built the system.

When I contacted Asus for support they, fairly, pointed out that Intel technically only supports memory speeds of up to 2400 (On the 7700K I'm using anyway, my sticks are 3200).

https://ark.intel.com/products/97129/Intel-Core-i7-7700K-Processor-8M-Cache-up-to-4_50-GHz

I was excited to see a new BIOS thinking it might fix my woes with XMP, but I see more nays than yays on this thread so I will refrain from this one for now. As a previous user pointed out, BIOS updates aren't like your mouse drivers. You shouldn't apply new BIOS unless you are fixing a problem or adding support or a feature you were lacking.

Same XMP problem here with z270G motherboard, i7-7700k, and 16GB corsair 3200mhz RAM

On bios 0801 I have a stable 4.9 GHz overclock with XMP memory setting

I am looking forward to trying out Optane, so I upgraded to BIOS 0906. With all BIOS settings the same as I had in 0801 including XMP enabled, processor speed is locked at 800MHz and won't boot into windows on most attempts. Even downclocking to stock CPU speeds but with XMP option, the processor is locked at 800MHz. I will look at the IO and SA settings and give that a try.

Even if you refuse to consider the 0906 BIOS "bugged" or "flawed", don't you think there should be instructions offered with the 0906 BIOS to "tune" the IO and SA voltages (if this is in fact the source of the problem) when using XMP and experiencing problems? This does not appear to be some extremely rare or isolated issue with this bios version, based on the number of folks that have chimed in on this thread. Not everyone with 0906 XMP issues will make it to this thread to find the remedy.

I am also having problems with the BIOS (already tested three versions 0701, 0801, 0906)

My setup;
Maximus IX formula
Intel core i7 7700k
32gb Corsair Vengeance LED 3200 (2x16gb, CMU32GX4M2C3200C16)

When I select XMP profile;
On each cold boot my computer is acting weird. When I press the power button the pc powers on, then immediately it turns itself off, then in 2 seconds it powers on automatically and boots to windows. Restarting the pc works fine.

I hope Asus will fix this in the next BIOS update.

Yes, works perfectly fine to "roll back" Make sure you remove the battery and leave for 5 mins. Press the power and reset button a few times to help discharge board. If you do not have to reset the bios time then you have not done a full reset. I always use a USB stick with the CAP file on it as the method to flash the bios. Things are very easy now as even the USB 3.1 port is active to read the bios file and the tool section in the bios page makes things very easy compared to my very first PC build. Flashed my own board back to 0801 bios, reset clock, reset the XMP profile, overclocked the processor and GPU in bios (the best way, forget using DIP5 software) and viola! Back to 4.95ghz and GPU running at 1350mhz. Easy peasy.

Hi all,
After updating the 0801 bios to the 0906 on my Z270F, I was unable to boot windows, I even had system freeze while into the bios. It appeared that XMP was causing system instability while it was perfectly working before. I had to select by hand the DDR4-3600MHz ram speed instead of the default DDR4-3733MHz that was perfectly stable before...:mad:

I guess I am so used to manually tweaking my settings that I never noticed how different XMP values are from what is actually needed when running memory above 3000mhz with 0906. Chino and a few others are absolutely correct that no speeds above JEDEC specs are guaranteed and that it may indeed require manual tuning. XMP only refers to what works for the memory sticks, it never guarantees that the particular memory controller in your CPU will work well with those settings. Too much variation in the silicon. So for anyone that wants to run 0906 just tune your VCCIO.

That all said, I would agree with the group here that the Auto settings of 0906 under XMP are likely not well assigned. I'm not sure what CPUs and memory Asus was playing with that needed such high VCCIO, but of the few CPU and memory kits I have here on my bench, none of the combinations run with XMP. Hopefully Asus engineers tweak that back where it needs to be on the next BIOS to aid less experienced users. In the meantime, if you want to OC beyond JEDEC specs, I suggest users get familiar with some tweaking. It's a good idea to know your BIOS and what settings do what. Many times XMP and Auto values will run voltage beyond what's needed for stability. A system may run well under Auto and XMP settings but may also be over-volting your components. So an astute user should always go back and try to work their voltages down from stable Auto settings to save on needless heat production. Its a good lesson for less experienced users.

I don't bother OC'ing my ram either (Corsair Vengeance RGB 32 GB DDR4 3200 MHz), I just use the xmp profile. I am wondering if I should just go ahead and update to 0906 if you aren't seeing any negative impact after using it.

You do know if you run the XMP profile you are overclocking the memory, all DDR4 memory is 2133MHz. When running the XMP profile you are just having the motherboard read preprogrammed timings, memory frequency and voltages embedded into the memory. If there was an issue with the bios ASUS would have pulled it from being downloaded. There is absolutely nothing wrong with the bios and memory. I have both my VCCIO, System Agent and DMI voltage all set to 1.3000v along with DRAM voltage at 1.510V and everything is ok. BIOS's are only created to correct things and make things better. These are ethusiast boards (ROG / TUF) they are designed for OCing, same with the memory. I for one are appreciative of the OC profiles ASUS implements into the BIOS's, you don't see that much with other brands and they work as intended and not work in a negative way.

Just to have clear details: DDR4 memories are with base 2133Mhz and 2400Mhz and with the 7th generation of Intel CPUs, the native base frequency 2400Mhz is supported... Just the problem is, that Asus does not support base 2400Mhz memories, just 2133Mhz.

I tested more DDR4 memory packs with base 2400Mhz on my Asus Maximus IX Code, I tested them with 2 pieces of 7700K CPU and they just did not work. The MB did not get into the BIOS with them, so any tweak is possible with them.

Also for some reason, I am not able to downgrade my BIOS. It keeps complaining the CAP file is not valid. I even tried renaming the file to Z270SE.CAP as I saw was suggested somewhere on a forum, but that didn't work either. Anyone any suggestions?

Strange, I just happened across this thread doing a search for a beta bios newer than 0906. Surprised so many people are still having issues with it. I've been running it since I got my Formula and havn't had a single problem. I'm going to leave it as-is unless I notice weird behavior but it's been 2+ weeks without a hiccup.

This is on 0906 I started at 5.2ghz on the original bios 0504 or something it shipped with and 0701 and was fine but the 2 latest versions seem to over volt the cpu and cause heat issues. Might try backing off the xmp profiles(which set my bclk to 103 and the ram to 15/15/15/36) I reset the bclk to 100 and most of the overheating stuff went away( I am using a corsair h110i v2 240mm aio).

Bugs I've found so far with Z270E 0906:
-Enabling ERP will cause the system to unable to POST when restarting PC (sometimes when trying to enter BIOS again but stuck on black screen and have to hold the power button to force shutdown)
-RGB LED option in BIOS for turning OFF during S4/S5 doesn't work 99% of the time. Lights will always be on during S4/S5. But when ERP is enable and RGB S4/S5 is set to OFF, lights will be on during S4 but will be OFF during S5 (so half work).

For those of you having the issue with cpu locked at 800mhz go into your windows advanced power setttings and under processor power management
set maximum processor frequency to 0mhz or you can set it to 1000mhz over what your maximum overclock is set to. I.E. you are overclocked to 5000mhz then you would set it to
5100mhz.

1. Turn on the powersupply first (needs to be turned off)
2. Turn on case power button
3. Press case restart button
4. Then it boots into windows

I mean seriously.

Furthermore you need to provide a more detailed explanation around the XMP settings in the BIOS in the manual. So many people from what I can see in these forums are RMAing their mobo's cause they think something is broke and don't know it is the Ram and Kabylake. It is costing you guys money!

I thought I'd chime in on my Asus Strix Z270G board.

With this BIOS update;

1) Motherboard will never power off after a windows shutdown. All the components seem to power off, but the LED on the case never goes out, and the Corsair Hydro never spins down. I have to hold the power button in for >5 seconds for the board to power off.

2) The reset button doesn't work. Bonkers that one.

3) All drive performance is through the floor. *M.2 MSATA in in slot 1_1, normal spinny Seagate Barracuda in the SATA 6G_2 port, Bluray writer in _3. Read/write speeds are terrible.

4) Enabling Intel RST through the BIOS is another nightmare, BSOD, drivers wont install, and getting up to 2480ms response time on the spinny drive.


I've rolled back to version 0801 BIOS, and it seems OK.*

When can we expect a BIOS update with all the mentioned problems fixed? I wont try an update as long as so many people tell about problems.
My main reason for updating the BIOS would be the poor boot times (NVIDIA recently tuned the drivers so the boot times on systems with large amounts of RAM and M.2 PCIE drives boot faster - dont ask me how this is linked together with the graphics card, but my computer needed nearly one minute to boot and after contacting the support and after their latest update it is better now).
Post times are quite long and M.2 performance might get better...

Just to add my two cents worth, I've had no problems at all with this Bios version. I don't usually up date the Bios unless it has some advantages like performance or stability improvements. Not interested in Optane or the need to be able to run MemTest with all cores or what ever else was in this update. So I thought I'd try 0906 just to see if my board (Hero IX) would act up. Boot times are as 0801, XMP works as it should, even managed to drop the VCCIO to 1.168V along with VCCSA at the same voltage. Fixed CPU at 1.136 and run the CPU at 45. Memory running at 3200 at 1.344v. all four slots occupier total 32GB.

It's rock solid and I've given it some stick with AIDA64, RealBench and Prime 95. Whilst this is no consolation for those that are having problems I guess I have been lucky with my set up, being that this is my first ROG board, my previous board was a Z170-WS.

Don't give up hope, Asus will sort this eventually (fingers crossed).

Having same issues as most of people in this thread.

It's been driving me absolutely ape bonkers.

I've exchanged every component in my build at least twice trying to troubleshoot the start up issue.

If I shut the computer down, or it goes to sleep after an hour of idle it's almost dame near impossible to get back on.

Should I revert back to old bios version?

Everything in my bios is set to auto with the exception of fan speeds, ram settings, system agent and vicco set to 1.2

Hey guys,

Strix Z270G
GSkill 16GB 2x8GB DDR4 Trident Z 3733MHz ( Memory transplanted from previous build MAXIMUS VIII GENE Z170, worked perfect on that one)
I7 7700K

I am having these issues too, the 800mhz issue when using XMP, with either the latest bios or 1 version back doesn't change for me. I found it to be hit and miss in terms of with XMP on, some boots I will get full speed and some I wont, some times get the shut down issue where it doesn't actually power off and some times works good.

with XMP off every thing works perfect every time, I can even get the CPU to 4.8Ghz on stock voltage ^_^ so cant be a bad CPU ?

Worst thing is I only just sold my old board VIII GENE (Z170) as I wanted a extra M.2 slot and was doing a new custom loop build and liked the neutral colours, wish I never changed now, :(

I have also opened a support request, see if I can get any feed back.

Even if I manually program in my spec settings not using XMP after factory rest the issue appears, something about setting a high speed memory ? Keen to follow this thread for every one else's feedback and input, some thing is not right !!!

Are you able to save oc profiles to memory stick using either F2 or ctrl+F2 or whatever it is?
Bios has freezing issues, mislabeled functions & many issues named in this thread

Just to name a few issues (and this is a fresh UEFI windows 10 pro install no clone drive etc.)
Ram Cache II - (stops randomly with "Incorrect Function" error - had to uninstall.

AISUITEIII - Doesnt recognize my Aquacomputer D5 PWM pump on the Water pump+ header just runs @ 100% (and this is the header designed for PWM pumps!) Many people all with different brand PWM pumps reporting same thing. I would be curious if ANYONE has a pwm pump working on this header.
Spent weeks troubleshooting, had to give up.

Aura - yeah this one is ridiculous! Aura is corrupting G skill RGB Trident Z dimms to where the SPD info gets corrupted and the LED's all go completely dark. Most dont come back with G skills recommendations so for those of you that are like "my RGB memory is working fine" I suggest you prepare to purchase Taiphoon Burner so you can reflash the SPD on all your dimms when it happens or prepare for RMA cause its only a matter of time. Dont believe me do a google search!
At least G Skill has their RGB software in Beta where as Asus doesnt and G Skill just released a new version (not sure if it 100% resolves the dimm corruption issue) but at least they are trying. Note: I have never installed G skills software, only Aura and it corrupted my modules after the first 7-10 days of using it. Thankfully It was within first 30 day exchange period ( I was unaware of Taiphoon burner at that time).

Audio Issues such as bad echo and wierd almost lazer like sounds- may be resolved though but hard to tell cause its intermittant, more game time required and tests.

Cant get any response from Asus in the forums it seems about any issues on Z270 and the driver updates are very sparse, Pretty sad considering nearly the whole line of ROG boards run off the same software and bios and this is a motherboard refresh, shouldnt most issues be worked out from Z170 anyway?

BTW - I did try openeing a ticket with Asus support and the response I got was laughable and frustrating. The "Technician" trying to help me out was probably searching toms hardware for my answers to the AISUITEIII issue cause he wanted me to test things that had absolutely nothing to do with the issue. It was like he didint care and/or know what he was doing.

Mine is a "Strix Z270H".
After the update, my computer was unable to come back from sleep/hibernate state. Every time it went to sleep, it was like the computed died.
Even the power button woudn't work. After turning it off/on, the light went on, but there was no POST, no fan activity.
The only way to get it back working again was to unplug it for a couple of minutes. Some scary ****, as my set was a month old, and it was running smooth).
But what scared me the most was that it also happened when I turned the computer off normally (through Windows), and not only after auto-sleep. I coudn't turn the PC on afterwards without unplugging the system for a couple of minutes. Again, just the green light, but no beeps.

Turning XMP off solved the issue for me (thanks to this thread). It was the only non-default setting in the bios.

Now I just can't use it anymore, as I'm too lazy to flash the older bios version :p

The lack of response is somewhat annoying. Especially given the cost of the boards that are experiencing problems.

I for one would love for my overpriced motherboard to decide it wants to boot up reliably every time.

Currently this whole 1 out of 10 boots is a hang thing is... very no bueno.

Also the whole water cooling focused options in the BIOS are utter garbage. Where is the ability to set the fans based on the cooling loop? Why give me the ability to monitor the in and out temp of the loop at the CPU block if you're not going to allow me to use it in any meaningful way other than "wheee. look at the numbers. I has numbers. yay. numbers change."? One has to run an extra thermal probe to do that, even though there are a pair built into the monoblock.

I shoulda returned the board as soon as the bios problems cropped up. But lazy is as lazy does, and damn those pretty lights and Bitspower block for making me stick it out.

That's interesting, I posted a while back about getting 55 errors when first setting up my system (Maximus IX Hero), but they didn't come back after that time.

Since I was having crashes in games, I decided to flash the BIOS to 0906 and it takes longer to boot sometimes (multiple boots maybe?). The main thing is, I ran Memtest and my memory (G.Skill F4-3600C15-8GTZ ) gave errors. When I turn off XMP, the memory gives no errors. I'm not sure if the motherboard or the RAM is the problem. I've opened RMAs for both at Newegg... I don't suppose there are BIOS settings I could try to make this memory actually run at its advertised XMP speed normally?

I am also one of those with unfortunate 0906 issues.
I use a Strix Z270G mATX.
Only problems i noticed happens with XMP enabled.
After enabling XMP my computer will not shut down properly from windows, the screen goes off but the fans keep spinning until i hold the power button.

Also with XMP the processor will max out at only 800mhz and also the GPU gets cut down.
However after i OC'd my DDR4'S manually to 3000 by altering the VCCIO etc, everything works smooth. I recommend manual tuning for everyone having issues with XMP profiles.

What settings did you change to manually OC your memory? And what values did you use? (e.g, what DIMM voltage, what VCCIO/VCCSA/etc)

I think the problem is in the XMP, turning the voltages way too high.
In the BIOS AI Tweaker i just set the Ai Overclock tuner to Manual,
I changed the DRAM Frequency manually from the drop down menu to 3000mhz (Because I have only up to 3000mhz Corsair Venegance DDR4's)
DRAM Voltage to 1.35
CPU VCCIO Voltage to 1.15
CPU System Agent Voltage to 1.15
Core and Standby i left on AUTO.
Did not change anything else, or just left it as AUTO.
After this I got the memories working at 3000mhz and stable.
Of course this works differently on different setups, but this is how i got my memories working full speed without problems. :cool:

06-15-2017, 03:46 PM
Thanks! I turned off XMP and set memory to 'DDR4-3600' in the frequency menu, voltage to 1.365 (so it would be 1.36 stable, otherwise it drops to 1.34 for some reason), and Memory Tweak to Mode 2 (which it was already at, it puts VCCSA/VCCIO at 1.2 and 1.27, forget which is which) and got no errors in Memtest.

One thing I noticed is that the 256k L2 Cache speed in Memtest dropped from 115 GB/s to 95 GB/s. RAM speed dropped from 29.5 GB/s to 28.5 GB/s.

What other settings was XMP overclocking to cause that difference?

Btw, without XMP, which setting is equivalent to 'all core enhancement' so I can manually enable that?

Updates on my situation in this thread:

https://rog.asus.com/forum/showthread.php?93973-Getting-errors-in-Memtest-with-RAM-at-XMP-(IX-Hero)

There seem to be varying timings coming from the data on the modules themselves via the Asus SPD tool and what it picks up when you actually run it in XMP mode. And there are other people online coming up with different timings for the same memory as well. Here's a spreadsheet showing a comparison of what I've found so far (https://docs.google.com/spreadsheets/d/1wdZpzS2M-PCpdDR3MSKfdb5ei0nqepf3paFtuuq2XAo/). And while it tends to be more stable in non-XMP configurations, I can get XMP somewhat stable by upping the voltage to 1.45v.

So... is my hardware bad or is the BIOS doing crazy things with the timings? For what it's worth, it completed the 2.5 hour Memtest run in DDR4-2133 mode and DDR4-3600 17-17-17 mode without any errors.

Is Memtest a good way to test all this? It will pull errors if something's wrong, I assume? It seems to have done that so far. I just don't want any false negatives.

Anyone having inexplicable problems with the XMP settings, try upping your DRAM voltage to 1.45 and see if it's stable. (it won't harm your computer to run it like that for a little while just to see if it works... long term, maybe someone can let us know if that's dangerous)

My ram @ 1.45v hits 48 C while gaming (used to be 42-44 C at 1.35v).

Yes. you can use HWinfo64 and SIV64X (these is more complex program is very detail and take time to get use to it) but reads every single senson on the board) Be noted that use these last one to read. I always use 3 programs just to be calm on some times. I find out that HWinfo64 is the best for the ASUS motherboard. Aida64 also can ready ram voltages but you have to activate the reading tap on voltages in the tap to read the volts on the ram! Use HWinfo64.

Could these 0906 bios issues (I haven't read through this thread) cause cpu temp fluctuations? I was on a MSI B150M Mortar Arctic w/ 6600K idle windows w/ firefox and MCC playing a video temps were 28-31C . Since upgrading to the Z270G my cpu temp is all over the place (and yes I have wasted time pulling the H100i GTX and reapplied TIM) 28-54C. Currently while watching temps for the past 3 minutes with just standard things running in the background and this FF browser open I'm bouncing around at 29-34C. Open a video with MCC and the temp bumps up to 44C for a second or two then back down to 31-38C while playing the video.

To me it seems it's getting much higher then with the B150M and sure if fluctuating around alot more. There is no overclock on the system and my cooling config is exactly the same from the B150M. As mentioned sometimes it gets into the 50C+ range while just watching a video and browsing the internet (4-5 tabs open)

I did use all latest asus drivers. including audio aura (asus need to polish that better) Aida64 was ok (1h run), is raining here so temps are 26C at 75% humidity. cinebench was ok to CBCPUX=1013.402245 i did see some pause on second run. (still checking that) My rams are on XMP 3200. I will jump to 47 next week since i know that these small jumps need more vcore. untill i see that these current settings is ok and stable i will continue.
