I do a lot with ram oc. and my setting was always fine. i stayed for nearly one year on 2A.40.
now after alle the new vulnarys where fixed in may, i decided to go to the next non beta Uefi fw.

yesterday 2A.60 was release by msi.
i set all my old values for pbo and ram oc. the benchmarks are identical. karhu runs without any issue for 30min. for a longer test i didn't had enough time yesterday,
because 2A.60 doesn't like reboots. which values i shoud have to change or is it any general issue of the agesa?

Out of curiosity since I have the exact same motherboard + Win version and also just flashed A60, what do you mean by "doesn't like Reboots out of windows 25h2"?
Since flashing I rebooted 2 or 3 times so far with no issues.

I found the error! The resistance CA, CK, CS "ODT B" values for 2A.40 and 2A.60 changed automatically via the "Auto" preset!

The automatically assigned resistance values for 2A.60 caused a crash upon reboot!

these are the manually set resistance values derived from the "Auto" settings for 2A.40, which I had determined about a year ago.
The AI wanted me to set ProcODT Pu and Pd to 43.6. However, a successful reboot is only possible when running asynchronously with values of 40 and 43.6 (which correspond to the old "Auto" values). It is astonishing that the new AGESA version altered the resistance values—which I had previously always left on "Auto"—in such a way, and that, conversely, only the *exact* resistance values from the old AGESA 1.2.03c "Auto" settings work correctly with AGESA 1.3.0.1b!

Have similar reboot issues with exact same RAM.
My issues is with using EXPO Profile1. After setting it in BIOS everything works on first boot (6000MT/s). After reboot there is long memory training and values will set back to JEDEC defaults (4800MT/s) and in BIOS EXPO Profile1 stays/shows "Enabled" (but thats just cosmetic bug).

EXPO Profile1 (6000MT/s) vs after reboot defaults
