In hopes of saving some time, I searched for examples that actually functioned. The specs I have are a Ryzen 5600x with PBO and various settings to achieve around 4.7GHz for all cores and 4.8GHz on single core. I’m using a Klevv Bolt at 3200Mhz CL16 with settings like 18, 38, 1.35v and running two 8GB dimms. I managed to push the RAM up to 3800Mhz CL16. I spent considerable effort testing different overclocks and configurations, especially balancing performance gains against the impact of async and command rate. I attached my userbenchmark perf, along with AIDA 64 perf and a screenshot of my current settings. I followed a guide from Integralfx that proved very useful. Please note the tRFC calculation method I used (ns × ddr_freq / 2000) to reach a target of 260ns; I adjusted to 494ns for stability. I found that tRFC 250ns is unstable, while 497 or 494 works well. The table included helps match tRFC values to RAM types and frequencies. This is the most detailed I could provide. If you have any ideas to improve this, let me know. Also, I manually overclocked the 5600x and ran Cinebench R15, achieving 2014 versus PBO, while manual scaling gave 2045. I also updated RAM timings to 16-19-20-28 at 3800Mhz and adjusted ProOCT CAD Bus Strength settings, which helped further. Rttpark was set to 34ohm CPU, VSOC at 1.0875v, and I changed the ProOCT settings to 20ohm or 53.3ohm for better stability. Updated October 13, 2021 by Qk321. Pictures included.
