Hi lads,

Need your input :p

Got a good 780 ti.

As mentioned in some other thread, running 1360MHz/8100 on 36x.xx and 1470MHz/8100 on 34x.xx, 1.138v, gaming stable (benching with +30MHz, no artifact, but crashing after a while, same voltage). I don't even want to know the reason why... Not an issue as it gives the same score on Heaven/3dMark22/3dmark.

Temps are real low: 41c max after hours of benching gaming (no vsync, to run the [email protected]%).

Theoretically, it still have 0.1v of margin (max stock), or 0.17v (unlocked).

The thing is that anything above 1.145v and it starts artifacting/crashing. And it is VERY touchy regarding that.

1360/1.138 is stable for hours. 1.360/1.45 artifacts almost instantly, and crashes.

Just out of curiosity, could it be VRM related, or just silicon?

FYI, it is lower than stock volt (1.15v)...
