AM I THE ONLY 1 THAT BOUGHT A Z270 CODE.... thought it woulda been the sweet spot between the extremely high end and the entry ROG boards

Bios for IX CODE is now available. Check 1st post.:)

I took the leap and dropped 0906 on my Hero ... so far so good.

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.

Thank you for posting this. It doesnt show up in AI Suite Update yet.

You left out the most popular, The Z270 IX Formula! Download HERE


BIOS link was not present on ASUS site for Formula at the time of writing the post. But thanks for that. I have updated the first post.

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.

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?
