Test BIOS with new AGESA 1004a, with a couple of bugfixes. Up to 5% performance increases in specific applications. Also has P-state overclocking working with BCLK increase. If you want to keep C-states, make sure to set Advanced\AMD CBS\Zen Common Options\Global C-state Control = Enabled. There are two new settings under AMD CBS\UMC Common Options\DDR4 Common Options\ you might want to take a look at, Fail_CNT and ProcODT. Fail_CNT decides how many times to retry when DRAM training fails (F9 -> 0d), default is now 1. ProcODT can help improve your DRAM overclocking. There's a setting available also on previous BIOSes under AMD CBS\UMC Common Options\DRAM Memory Mapping named BankGroupSwap. If you have 2x Single-Rank modules you can try setting this to Disabled and you might see some performance boost in certain applications.Test BIOS 0081
Same as 0079 but has ProcODT default = 53.3 ohmTest BIOS 0082
Same as 0081 but with a DRAM compability patch for the below part numbers
M378A1G43EB1-CRCTest BIOS 0083
Same as 0081 but with "2T" DRAM Mode when using above 2666 DRAM Ratio.
C6H + 1700 and these new bioses are DANGEROUS!
With previous bioses +0.1v offset was 1.31v
With these new bioses +0.1v offset was over 1.4v!
So when I reapplied my previously valid +0.25 offset I got way over 1.5v! Almost 1.6v! Red in bios! CPU melting!
After lowering the voltage back to safe levels I tried to save Pstate OC. Nope. Did not work. Tried slower settings. Nope. Did not work. I was not able to save any pstate OC with these bioses!
Before and after flashing: Clear cmos (over 10 seconds), load default and reboot. No help there.
Now I'm back to 1002 that works just fine. Memory max 2666 but at least it's working. Be safe and test low voltage before applying the "good old values". They might be totally different with the new bios!
