A new BIOS has just been released for the Z790 based MB's. Release notes are:
1. Improve system stability and compatibility for the next-gen processors
2. Fix the compatibility and instability issues when configuring RAID for high-capacity storage
3. Do update the intel ME to version 184.108.40.2066
It's right there staring in your face: https://dlcdnets.asus.com/pub/ASUS/mb/03CHIPSET/MEUpdateTool_220.127.116.116_T.zip?model=ROG%20MAXIMUS%...
I ran the MEUpdate and the BIOS update and all us fine.
Just tried to use this BIOS on my Z790 HERO, after grabbing the latest MEI/ME FW and chipset drivers from the Forum, since it would appear ASUS pulled them from the download page for our boards (which should have been my first warning).
I updated all the MEI crap, and went for the BIOS update. This resulted in me being sent into a bootloop right after it rebooted on it's own as apart of the update process. As soon as the keyboard was initialized and the monitor woken, it would restart the boot sequence. Never settled on a Q code.
I allowed this to continue for 10 minutes before shutting it down. I then cleared CMOS and attempted to boot again. Same issue.
Ended up having to perform a BIOS Flashback. Went back to my previous version (0816), and so far everything appears to be working as it should again, though I have only restored my BIOS settings, booted windows and ran CB23 multicore for 6 runs so far.
Quite a bit of discussion about stability issues with 1202/1203 for Z790 boards over on Overclock dot net as well, so I think it's safe to say, between that, and the ME FW being pulled, this update is bunk.
Asus, you need to get this sh*t sorted out.
Can you let me know what ME firmware you believe was pulled from the support site? The latest BIOS was released over the weekend, I don't think 18.104.22.1686 ME has been added there yet.
Can't say I've noticed any issues on the latest build @ 8000MT, was previously on 0801.
I said it would appear, since a few over on Overclock dot net were saying that 2176 was available and then was pulled, and a few seem to think it was causing issues.
I didn't personally see that. I only noticed that it wasn't available, then grabbed it from the Forum. I haven't noted any issues with MEI/ME FW or the MEI Driver updates, but again, the 1202 BIOS sent me into an unrecoverable bootloop when I was previously fine (and am again after a rollback).
I see. I'm not sure that's accurate but will investigate.
Overclocking stability across builds hasn't been an issue for me on the APEX but it can often be challenging to look into vicariously.
Sometimes [but not always] the overclock may have been conditional to begin with. It's also not uncommon for ME firmware updates to break overclocking. The Management Engine controls a great deal including some of the start-up routines, hence why it is important to run the correct ME Firmware for the BIOS revision (something you may already be aware of).
It is also important to update the ME Firmware prior to updating the UEFI.
Yes, I used the "link" in this post. Will take you to a download site for the ME 22.214.171.1246.
Copy and paste in the search bar: [FIRMWARE] Intel ME (B660/H670/Z690/B760/H770/Z790)
As always, follow links and download at your own risk, but so far so good as far as working for me. Hope that helps.
