I'm trying to stabilize my RAM OC and have been adjusting VDDG CCD/IOD voltage. I started with Default bios so the timings are very loose. I will tighten timings once RAM is stable.

TM5 Ryzen3d profile + FurMark:

  • At 950mV: failed at 1.5 hours
  • At 970mV: failed at 3.5 hours
  • At 990mV: failed at 12 hours

My max RAM temp got to 53deg and 52deg.

Should I keep increasing CCD/IOD voltages to the max 1050mV?

System:

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