ROG STRIX Z790-F GAMING WIFI Bios 2801 not booting with XMP

[Nemke]

I updated the MB bios so i can get the new inter Micro Code fix so my CPU is safer. SO i had to update Bios to 2801. But after doing that the stable XMP profile i whose using didn't want to boot any more so i tried a couple of things and lowering the XMP from 6800 to 6400 preset works. Do we know why this is happening when the micro code is updated. I did do a search on the forums and it seems that installing a older version of the bios didn't help so it comes to the Micro Code i guess.

Im hopping this stays stable like it is i just changed the bios 1h ago and fixed the boot now so lets see. If anyone else had these issues please suggest any other potential fix. 

My ram is 4x Kingston Fury Renegade 16GB 7200Mt/s

Adjust Voltage Settings: Increase CPU VDDQ and CPU VDD2 voltages to enhance memory controller stability at higher frequencies. However, exercise caution and consult your motherboard's documentation to avoid potential damage.

Revert to Previous BIOS: If the issue persists, consider reverting to the previous BIOS version that provided stable XMP performance. Be aware that this may reintroduce the microcode vulnerabilities addressed in the latest BIOS.

Contact Support: Reach out to ASUS support for guidance on achieving stable XMP performance with your specific RAM model and BIOS version.

As far as i know the micro code is a permanent thing as per the documentation on the official download page

Please note after you update this BIOS, the ME version remains the updated one even if you roll back to an older BIOS later.

But yea im not risking going back to the older version. But i will look into voltage to basically do  manual overclock but first i will do lots of research on it so to not brick my system 😄

Microcode can be reverted, the ME Firmware cannot. However, it's highly recommended to use 12x0b due to it mitigating voltage issues. 

It's also not uncommon for the management engine firmware updates from Intel to occasionally have an impact on overclocking, however, in my experience it's normally due to the overclock stability being conditional in the first place.

O ok i thought the Micro Code and ME whose the same thing thanks for the clarification
