Question XMP Profile is not stable with new Bios

[SalahEid]

i recently update my B550 AORUS ELITE (rev. 1.0) BIOS from F13 to F15a the latest ver. (to upgrade windows 11) and i get a lot of errors and crashes
My RAMS : F4-3200C16D-32GTZKW Trident Z DDR4-3200 CL16-18-18-38 1.35V 32GB (2x16GB)

i do some research and do these steps :

• change DRAM voltage to 1.38v : 1.45v (not stable)
• manually set the frequency under 3200MHz (not stable)
• do test on my rams memtest86 each ram alone (0 errors)

on F13 i didn't get errors try to downgrade to F14 and same errors .. now i'm on F13 and till now no errors or crashes
anyone have an idea for this problem ??
thanks in advance

The voltage for the ram kit per the kit's spec's page state 1.35v for those frequencies. Set the frequency, timings and voltage manually in BIOS. FYI, you shouldn't be on 1.2.0.5 to begin with since that's what caused all the headaches for AMD platform users. You should be seeing a 1.2.0.7 BIOS version in the not so distant future.
