problem with watercooled 660 ti

post #1 of 7
Thread Starter 
hey everyone,

so i watercooled my nvidia branded 660 ti by using a h55 corsair cooler and zipties. i mounted a 80mm fan on the stock memory heatsink. temps were amazing (52c under full load), but i get crazy artifacts when benching with valley and games crash pretty quickly. i reverted back to stock and no problems, but temps get alittle high again (76c when at full load). any idea what could have caused the problems?

btw, i had nothing else on it besides the cooler ziptied to the chip and the fan ziptied to the mem heatsink

Sounds like the installation did not go smoothly, but i could wrong.

Can you not add a bit of voltage to see if it stables out?

i have the bios of the card modded to allow 1.212 volts. also, i'm using a thermaltake black widow 850 watt power supply. i'm thinking because the gddr5 ram wasnt being cooled at all it my have happened, because it only had problems when the card was being stressed, never at idle
