Just thought I’d show off, as I’m pretty pleased with these results for a first attempt. Appears to be stable so far.
My modded sapphire 7900xt reference card (deshroud + kryosheet + delta fans) is stable at a boost clock of 3,450 MHz with a 270 W power limit. No undervolt is necessary because the temperature never goes above 60-65 C. Also bumped the minimum clock up to 1,000 MHz just for shits and giggles, made no noticeable difference.
I actually got a few successful benchmarks at 3,550 MHz, but it turned out to be unstable.
I’m using unigine heaven because it’s easy to set up on my computer and it’s free. Fought with time spy for a while, eventually gave up.
