I basically gave up on the EDC bug bec. i never could get it to work. Always had huge performance drops no matter what settings i used (didn't spent too much time but tried quite a few combinations).
Today i woke up early and my coffee told me to try again -> success!
Gigabyte x570 master bios F11
BCLK 100.3 (100.4 causes SATA to act up
G.Skill F4-3600C16-16GTZNC [email protected]
Settings that worked for me:
PPT/TDC/EDC 1200/540/18 (PPT and TDC are Board limits)
1usmus recommended settings except Global C-States: Disabled (with C-States enabled SingleCore performance drops significantly)
Dram 3800 with 1900 synced FCLK/UCLK and Ryzen Dram Calc 1.7.3 Fast timings @1.39V
Everything else (VCore/LLC/SoC etc.) at auto.
Now for some scores:
CB20 MT/ST: 7745/542
CB15 MT/ST: 3402/220
CPU-Z MT/ST: 8786/568
Intel-Burn-Test v2.54 High, 4run average: 154.3
Blender BMW: 1m48s
Blender Classroom: 5m24s
While it was fun finally getting the EDC bug to work for me I'm not comfortable with the Voltages/Power draw with these settings (see HWInfo screen during CB20 run).
HWInfo reports 174W max. CPU Package power during CB20 run.
Thanks to a custom loop the temps are fine
For Comparison my "daily" settings:
PPT/TDC/EDC: 300/230/230 (BuildZoid settings)
-0.125V Vcore offset
max CPU Package Power during CB20: 143W
Interestingly enough my CPU likes negative offset with BuildZoid settings, i get the the best scores at -0.125V.
Using the EDC bug the situation is reversed and any neg. offset lowers the scores (higher neg. offset ->even lower scores, tested from -0.025 to -0.100)
