ASRock Nova - Memory Assistance

[welshrat]

I updated my ASRock Nova board today to BIOS 3.25 (released today), I did this due to the issues ASRock have had with 9000 chips dying on their boards, I have had the build for the last 3 months and have run XMP/EXPO settings on my Kingston Beast RAM fine for that period. Today After the BIOS update it would not run at 6000Mhz on either EXPO or XMP (same values after going through them) however it would run at XMP 5600.

After trying to increase the voltage on the RAM on the XMP 6000 setting to no avail I compared the values between both and noticed that on XMP/EXPO 6000 VDDIO is set at 1.35v whereas on XMP/EXPO 5600 its was set to 1.25v so I tried manually setting the value to 1.25v on the 6000 settings and its working fine.

Can anyone explain this ? If I was to post my other settings here can anyone advise whether I need to lower or increase some values. I am not after really tight timings or anything as I know the X3D chips don't need it however it would be good to know that I am in the right area for these values given the preset didn't even boot.

Been running fine at 1.25v since yesterday so will keep it a that, really strange it wouldn't run at the default 1.35v though. Can't complain at lower volts though so hopefully all good

I think it may be due to Asrock bios update regarding the burning CPUs due to voltage on there boards, but I'm only guessing.

I have the taichi lite x870e bios 3.25, 64GB Gskill cl 30. I've got higher vddio with just expo enabled and manually set vsoc to 1.1v (level 2 load line calibration for vsoc):

Is this safe?

Maybe but this is the default expo profile for that memory. Strange it just won't work but then setting vddio to 1.25v fixes it.
