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.)


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

Do you believe that to be true even if it works perfectly fine under the previous BIOS revision?

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.

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

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!!!!!!

Using XMP is overclocking the memory. Just wanted to point that out. 🙂

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.

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.


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.
