ROG Strix Z390-F.
This new 2004 BIOS still gives me XMP/memory issues causing POST failures on boot that 1902 and 1903 also caused. Basically I can't run my 3000Mhz memory at any frequency above 2400Mhz without this .
I've had to roll back to 1802 just to use my RAM at rated speeds again. It's all rock solid stable on 1802.
Shame really, as I'm on Windows 11 and wanted an 'official' Windows 11 BIOS along with Resize BAR.
* EDIT *
Seems like the exact issue (for me at least) is that BIOS 1902, 1903 and 2004 all fail to POST with four DIMMS set to anything higher than 2400Mhz.
If I use two DIMMS, my rated speed is fine.
On 1802, four DIMMS works fine at rated speed as well.
The problem is in the BIOSs since 1902.
