Trying to squeeze more out of my G.Skill Trident Z5 RGB DDR5 6400 32GBx2 in Witcher 4, but I keep getting random black screens. Lower the offset?

Chasing max frequency was pure torture. I tried pushing to 6600MHz, but the second a fight started, I got a BSOD. I kept a 'failure log' of 12 different voltage combos. Under the conditions of report ID-GSKILL-OC-26, I found that anything above 1.4V pushed RAM temps to 82℃, causing instant instability. I stopped fighting the frequency and instead went into the BIOS voltage panel to set the offset to -0.05V, locking it at 6400MHz. GamePP showed the power limit trigger frequency dropped from 5 times a minute to less than once. Frame variance became negligible, staying within ±2 frames. I didn't hit the 6600MHz dream, but this config passed a 48-hour stress test with zero errors. It was a painful process of subtraction, but the result is rock solid. Now I can finally ride through the Witcher world without fear.
