From my experience testing and tuning on Ryzen I think a lot has to do with how the motherboard handles things. After the updates for the 3000 chips on my mobo the auto settings decided to max out PBO. Last night I found where they moved the settings in bios and set them to the stock 2700X values. I also tuned the ram a bit tighter since my last post but with almost no change in scores. Auto is what my mobo seems to like. I can do a manual OC but then the voltage seems to stay at whatever I set it to and it wont clock down at idle. It would be nice to just set like 1.2v-1.3v and find the max frequency that is stable for it and say done.
if you use ryzen power plan (or win 10 balanced) and set c states/coolnquiet enable (sorry i forgot which one), cpu will run @ lower clock while idle
Ryzen 7 2700X @4GHz @1.15V
to lazy to do single xD
I also found this screen the other night. Setting it to best performance made it try to stay in a boost state (3.95-4.25GHz) even at idle even though it was on the regular balanced profile and I do I have cool n' quite on. Leaving it in the middle gives me the behavior I want out of my system like the lower clocks and 30ish degree idle.
Also your timings for 3200MHz ram are similar to what I had when it was stable. My Trc was 76, Trfc was 528, and CR was 1. Funny thing on my kit was that the Trc for the XMP profile was 60 and it caused issues at 3200 even though it was a 3600 kit. Only now at 2933 it seems stable. I have not tried to go any lower yet... its a pain when the pc does not boot and then testing for a while to make sure things are good... I'm just happy things are running normal or maybe even above average for what I have with a little bit of tuning and time.
yes, power mode not at best performance, i thought that i have forgotten something!
about ram speed, to my experience, the most helpful setting is always the voltage (dram < 1.45 and soc < 1.2), then misc modes and procODT resistances. dram calculator for ryzen helps a lot
my ryzen 5 3600 reach 3750 in multithread and 490 in single but I have overclocked at 4200mhz with 1.40v and ram at 3733mhz (3200 xmp) because if I put lower the test chrashed... v1.35 is good for 4050-4100mhz (temps 38-45 idle and 82 in full stress with arctic freezer esports 33 one)... damn I see people at 4200mhz with only 1.15-1.20v... so angryyyyy!!!! lol
