yah, figured that out
Ok, so the NV42, which I have, is completely screwed. I tested using HL2, which I've found to be one of the best games for stressing the entire system. I tried voltages 1.3, 1.33, 1.35, and 1.38. All of them hardlocked when I tried for 385 (my max before was 380) using software overclocking. Interestingly enough, 1.25, which I tested for the hell of it, showed artifacts and did not hardlock at 385, but I still exited because it obviously wasn't stable. Next I tried flashing clocks onto the BIOS. I tried 400/770 with 1.38v, and HL2 crashed immediately after I loaded a level, so I didnt bother going higher. Doesn't look like it works for the NV42
, but that would make sense because they supposedly are binned.
EDIT: Oh yah, temps never went above 65C, so it's a circuitry issue, probably parts that are only made to meet NU specs.
