7950X3D memory tuning, plus hottest RAM stress test?

    Do 2200 FCLK if you can. Also disable GDM, raise Dram freq to 6400 if its stable.
    Give 1.5 VDD @6400 with those timings

  2. Any voltages to tweak? BIOS update a good idea for newer AGESA?

    I believe it is a Hynix A die 2×16. I can’t post on 6200 with these settings. CPU seems to max Fclk at 2066 with these voltages.

    I typically max out around 65C (delta 45C) for memory in full system torture tests. I’ve tested it to be stable in 14 hrs of ycruncher, 24 hour custom blend (large FFT + RAM), 3000% memtest HCI, and OCCT ram test. All of the stress tests also had folding @ home running to dump an additional 300W of heat into the case. However, I did notice the readings on my sticks hit 79C max, despite never going over 66C in any of the above stress tests, so I’m confused about how its possible that it happened. Pretty sure I will have tREFI issues if operating around 79.

    AIDA latency varies between 62.5 to 64.5 ns
