well, i didnt voltmod, but i did take it to 540/720 with no problems. the max i have seen it is 79*C, but i will heat the room up and try again later. gainward told me not to worry untill 85*C anyway, so i will have that as my ceiling point, seeing as they said it is fine. if it breaks under that, then they will have to replace it.
the memory feels pretty darn hot, but runs OK. no artifacting problems in Deep Freeze like most of the 79 series are getting, and it runs rthdribl fine as well. when gaming, it is much cooler than when benching anyway. the max it hit in nfsmw was 74*C odd. i will try some more games later.
EDIT: new 3dm03 = 16805. yay! 17k is in sight!
EDIT EDIT: core maxed at 560, mem is at 800, at the end of the coolbits slider. i think that is high enough for me.
it runs everything fine, and i still havent seen higher than 80*C on the core.
