ROG CROSSHAIR VIII DARK HERO BIOS 4501 (2023/05/23)

Update AGESA version to ComboV2PI 1.2.0.A
Mitigate the AMD potential security vulnerabilities for AMD Athlon™ processors and Ryzen™ processors
Improve system stability

This is one of those times where if you are currently working just fine, don't mess with it!

I updated from 4201 and it wiped all saved bios profiles. I have pretty much all settings noted down but after entering it all, that's where problems began. It seems I can no longer run memory at 3600 (4x8sr) and am running at 3466 now with same C14 timings as previously. Running at default 3600XMP C16 will not post so that's not a good start.

Can you flash it back to 4201?

I don't know. I'm going to try and persevere with this bios for now and see about tightening up ram timings for 3466. If there is a positive to be found it is that the EDC issue seems to have been resolved.

EDIT: I have 3600 working again. I cant clear cmos and jump directly to 3600 as before on previous bios versions, but if I start lower and build it up it seems to have sorted it self out.
