GTX 295 Single PCB Max Vcore ?

post #1 of 2
Thread Starter 
Hi there i'm running 2 x GTX 295 EVGA CO-OP HYDRO edition and i have overclocked them to

core 690 -712
Shader Clock - 1515 -1600
Memory clock - 1089 - 1112
(different for each of the 4 cores)

the temp on idle are 24 C max load 100% 39-40 C

I will do Single PCB GTX 295 Vcore mod like this thread http://www.xtremesystems.org/forums/showthread.php?231790-Single-PCB-GTX-295-Vcore-mod

How much will be the max safe vcore for 24/7 crunching SETI@HOME on temp not rising above 40 C on max load ?
stock vcore on my single pcb cards are 1.050V

You should be safe up to 1.2v since you've got them under water wink.gif Any higher and you're talking a borderline suicide run. It's really not necessary to go over 1.25 if you're folding or crunching, though.
