Pretty happy with final results. I know the AIDA64 latency test is not as popular or believed as it once was, but in absence of anything else here it is, 55.2 ns. I ran the AIDA64 Cache & Memory test in Windows Safe Mode.
Tests:
TM5 7+ hours (9 cycles) anta777 Extreme
OCCT (2 passes of 1 hour each) CPU+RAM, Large, Extreme, Variable, AVX2
I like the OCCT test because it stresses the IMC.
VDDIO is crossed out because I guess there is an issue with ZenTimings and some motherboards. It always reports 0.82v on Zen for me. It is set at 1.4v.
I have a FAN directly on the sticks. Idle temp is 32.
CPU idle: 43, GPU idle: 29
GPU: ASUS TUF 4070 Ti SUPER
BIOS Changes:
CPU Ratio: 48 (7900x is 4700hz)
CPU Core Voltage: 1.21v
Platform Thermal Throttle: 80
Curve Optimizer: -25 All Cores (I did not try 30, maybe soon)
I also posted a picture of my test results trying to boost the clock with CL28. I started at 1.5 VDD and got it to work and then messed around with some changes and then tried 1.45, no go, and worked my way back up to 1.5.
I tried for tRFC = 384 and tREFI = 65535, but the small incremental bump did not seem worth the extra voltages they would ultimately need. So I gave that up.
