CPU model is R9 3900XT with Kraken cooling. RAM is Viper Steel 4400 3733 1:1. I function properly without issues (1.025SOC - 1.35V). Boot fails if SOC exceeds 1.075V. With Cinebench R20, reboots occur unless I use specific settings: SOC 1.068V, VDDG 1000, DRAM 1.4V, timings loose. Boots with these but PC restarts during testing.

AMD prefers timing sets mostly. It’s not always the case, but Geardown is usually turned on by default for clear reasons. You might want to start primaries at 16-16-16-36 at 3800, then adjust secondaries and thirds from there. Good luck!

I successfully ran 16-16-16-36 at 1.43V and 1.05SOC. For tRFC I used 312/192/132 but the PC stopped eventually. I need to discover the correct tRFC so it works smoothly!

You're experiencing a very high latency of 59.6ns when lowering tRFC. Consider adjusting your settings or checking for potential bottlenecks.

Trfc appears okay. Mining at 665 at 3800MHz works well. Secondaries are tricky with my rig. 59.6ns on AMD is solid since it's built that way. I'm using 22-24-24-44 2T at 1.35v, averaging 53ns with 8700K.
