Follow up to my previous post here: https://www.reddit.com/r/overclocking/comments/1r3d26z/my_6200cl28_ddr5_settings_where_can_i_improve/
Memory is GSKILL Flare X5 64GB (2×32) 6000CL28. F5-6000J2836G32GX2-FX5.
I've spent a fair of time squeezing the remaining performance out of this CPU and memory and I don't think I can get much more out of it.
6200CL 26, 2200 FCLK, -15 CO
VSOC 1.19, other voltages in the screenshots are accurate.
I was really struggling to get FCLK stable at 2133+ until I realized I had overlooked FCLK VDCI mode. For some reason I completely missed that when I was reading over the BIOS settings for the 9000 series CPUs. After changing that from Auto to Predictive, I was able to get 2200 FCLK stable.
Verified with 16 passes of Linpack and 4.5 hours of Ycruncher VT3 – no performance regressions. CPU passed 11 hours of OCCT CPU+RAM torture test, and I've looped 4-6 hours of TM5 Extreme, 1usmus, etc multiple times to stress test the RAM.
Actual performance increase in real world usage is pretty marginal, but I was happy to see <65ns latency with 2x32GB dual rank sticks. Latency Killer is disabled. I did disable SVM which brought down latency a small chunk as well.
