X670E GODLIKE unable to perform reboot, but cold boot works fine.

[noncarbonatedclac159a02e3]

For a little while now I've noticed that if I power down my computer, I can cold boot just fine.
If I reboot the computer (from the OS, or in the UEFI after clicking "save changes and reboot") it just hangs with 00 on the post code indicator, and the DRAM LED lit up.

I've updated to the latest bios in hopes it would resolve the issue, but it has not.
I tried updating using m-flash, as well as the bios flashback button on the board.
I've cleared CMOS many, many times.


any suggestions?

Is memory A-XMP / EXPO being enabled in the BIOS? If yes, would the symptom occur with BIOS default settings?
Please provide full system configuration including the mainboard's BIOS version, memory module model name as the post advises: https://forum-en.msi.com/index.php?threads/posting-guide.38822/
Please make sure the mainboard's BIOS has updated to the latest 7D68v1L3: https://tw.msi.com/Motherboard/MEG-X670E-GODLIKE/support

EXPO was enabled, yes. The issue occurs any time there are memory changes (EXPO, manual, or optimized profile).
Issue does not occur after a CMOS clear, with no EXPO/memory changes (so, running a JEDEC default speeds)

Bump for visibility.

I ordered a PSU tester to see if something weird is happening on the power side.
I've passed 4 passes of memtest86+ on stock JEDEC speeds and AMP/EXPO (so 8 passes total)

I have not swapped to BIOS 2 yet. I unfortunately don't have another DDR5 kit to test, or another CPU/MOBO to test.

It's a known issue, see here:

Workaround: Manually lowering CPU NB/SoC voltage down to 1.25 V.

That seems to have done the trick. I need to run a some stability testing, but thank you so much!
