[ctorbaoglu]

Yesterday I upgrade to BIOS 4301 but all my previous settings not working.

Gskill 6400 mhz ranm unstable even reduced to 6000mhz. No atterntried different voltage and settings CPU and Ram not passed the tests on OCCT. They throe WHEA errors. 

I tested ram and CPU seperately but no luck.

I confirm this. Moreover, my system instability is unstable. The memory can successfully pass the MemTest86 for several hours, then I reboot the system, repeat the test, and many memory errors appear. It seems that there is some random instability.

I am also experiencing these same issues, I have 4 sticks of memory which previously could run at 5200 Mhz but now are only stable at 5000 Mhz, I know its small but It was stable until upgrading the BIOS to 4301.

Chiming in to say that I too am running 4 sticks DDR5 (128gb total) and was perfectly stable before newest 3001 update. 3002 just released so will see if previous stability is restored.

I tested 4301 on my Strix Z690 Gaming A D4 yesterday and it is a disaster for me lol, Most games crashing and some not even wanting to load at all without a crash to desktop lol, I flashed back to my previous trusty 2802 on my board.
