I am trying to stabilize my RAM OC with 6400, 1:1 mode, 2133 FCLK.

FCLK @ 2000 seems rock solid but I'm erroring out in TM5's ryzen3d profile. Other configs like 1usms v3 and absolut passed 50+ cycles over multiple cold boots.

What I have tried:

  • First Test Run: TM5 Ryzen3D + FurMark
    • Result: Failed after 1.5 hours
    • Mitigation: Increase VDDG CCD and VDDG IOD from auto to 970mV.
  • Second Test Run: TM5 Ryzen3D + FurMark
    • Result: Failed after 3.5 hours
    • Mitigation: ???
  • Ran Linpack Xtreme in safe mode for 40 iterations and the results look good.

Do you think this is an FCLK stability issue or something else? What else can I try to dial it in?

System:

  • Motherboard: Gigabyte X870 Aorus Elite WiFi7
  • CPU: AMD Ryzen 7 9800X3D
  • RAM: TeamGroup DDR5-6000 32GB (16×2) CL30. SK Hynix M-Die
