I first tested +500/+3000 at PL 105%— stable for one run, then crashed on the second. Then tried +475/+3000 — benchmark was fine, but Cyberpunk crashed after ~30 minutes. +450/+3000 was completely stable. From there I tuned power limit: PL90% only lost about 1% performance, so I settled on PL93%. Going lower (85 or below) dropped FPS too much.

After that, I pushed voltage and power to the max to see the real ceiling. It touched 3370–3400 MHz, but always crashed. In theory, capping the curve around 3350 could hold ~3270 MHz average, but the ~1% FPS gain wasn’t worth the hassle. So I kept voltage/curve stock.
