I am new to Zen 5, last time I fiddled around overclock settings I had an Opteron 165. After I got my 9800X3D, I worked on PBO settings and settled without MHZ offset and PBO down to -36 except Core 2 is -30, prime95 and y-cruncher passed without any issue and using daily for mostly gaming.
For the ram timings I followed Bullzoid. I have the same ram on his latest video as 2x32GB G.Skill only with the XMP profile version, when I bought these Expo version was not available. I am on Linux so I don’t access to every program but I tried out RAMspeed SMP and you can see below the difference with XMP and Bullzoid timings results.
The thing is, I followed his video on 2x16GB timings and I am not sure what each setting means and does. Ram temps don’t go past 52, mostly 50 underload, 40 idle. My timings are basically listed below, any suggestion is welcome
