I'm using Z790-F and updated to this version 1202, now my pc is very unstable, I can't use XMP again, I will go back to 0904. 

Level 10

Running 1202 on a Z790 Hero and running stable.  13900K with Gskill F5-7800J3646H16GX2-TZ5RK 2x16gb kit running XMP1 clocked to 7200.

Me too...exactly same specs....what a refund from the online shop and no updated Bios which fixes this from Asus....never Asus again! Never! Gigabyte as usual and everything works...period. So disappointed with them...

Seems to be stable, XMP on and so.

Here some feedback, when 1202 Bios version was installed my WiFi and BT will not work. I tried to install the INTEL drivers a few time to no avail.  Device manager showed a code 10 and a message of not having enough resources. 
Motherboard ROG MAXIMUS Z790 EXTREME, WIN11 PRO up-to-date as all drivers and AC. 
I had to reverse to previous BIOS 0904 and all works flawless.   I also noticed that the AC Does not show the correct CPU frequency, which it used to flawless and matched the AIO and CPU Core screen, Currently Stock (NO CPU) over clocking, only DDR 5, 4x 16  GB,  XMPII at 6400MT all works fine.  Adding this feedback for support to see as I tried to install Bios 1202 a few days after again, after reboot it worked al day. At end of days switched all off, including switch off at PSU. Next morning with the 1202 boot time was about a minute, way too long and the WiFi and BT gone again. Will wait for 1203 or later BIOS. 



haven’t seen any reports of Wi-Fi/BT issue after update. XMP is overclocking, revert to complete optimised defaults and see if problem persists.

Scone, is it okay when doing the bios update from the one the broad comes with from the box, or do we have to go incremental ie, 0904- 1202?

Can I just go with what on there from the box straight to 1202?

You can go straight to the latest version.  Just be sure to follow the ME firmware instructions and apply this before flashing the UEFI.
