Hello, feedback with my Ryzen 9 5950X on the Crosshair VIII Dark Hero (BIOS 2402).
Under watercooling 4.7 GHz 1.19v R15/R20 and 4.8 GHz 1.29v.
First test under LN2 with my Ryzen 5950X on the C8D. The CPU takes 5.8 GHz at 1.5875 volt (multimeter) at -155°C. I think I have a coldbug at -160°C and I also have a code 07 coming in while the FCLK frequency is only 1400 MHz. I will do another set of tests tomorrow.
SOC : 1.35v - VDDG CCD : 1.15v - VDDG IOD : 0.9v - PLL : 2.1v
Do you think my coldbug at -160°C can come from the FCLK? If I put a voltage higher
