Thank you guys, I am finally able to run my Samsung B-die RAM faster on this board together with the 3700X.
Not sure why I finally got it working better today.
3 possible reasons:
1. The new 5216 bios?
2. I did everything all over again starting from DOCP Standard and slowly working myself up to speed (the last time I didn't use DOCP at all, I did everything manually)
3. Better memory settings. I follow the advices from DRAM calculator. I believe one key for me may have been raising ProdODT to 40. I currently run DRAM voltage at 1.40 and SoC at 1.1. I think the calculator want me to raise DRAM voltage more but I am not sure I wanna do that. Gear down and power down disable. VDDG 950mv, VDDP 900mv
and not to forget... have heard my Corsair Samsung b-die from 2016 have worse binning than some others, for example G.Skill. This may also affect voltage needed for stability.
I have been running 3400, 3600 and 3666 today.
3666 almost stable but I got some kind of freeze in Windows after working a long time. Don't remember now if it froze when running [email protected]
or [email protected]
my guess is I had low DRAM voltage.
I am currently running [email protected]
and I believe it is stable, not 100% sure but I think so. Passing geekbench 5, userbenchmark, cinebench 20, time spy, firestrike and now my daughter has been playing LoL 2-3 hours.
Not 100% sure my system is stable yet but one thing is for sure, I will be able to run my system at faster speeds than 3200MT/s.
User benchmark (I guess the memory section is interesting)
Cinebench 20 is approximately 4997 (multi) and 499 (single)
Thank you for all advices, feels good finally being able to reach higher speeds. The difference is huge between Ryzen 3 series comparing to Ryzen 1 series on this board, uncomparable.
