Overclock XFX 7900GT

[thefear]

Hey dudes,
I just got some XFX 7900GT's and i put em in SLI, so now i wanna overclock em

Ive got 2 XFX 7900GT's in SLI and they both have 520MHz Cores.

Now my question for yas is, How much can i overclock these things until they blow up?, Ive got the stock heatsinks that came with the card, and i dont want to get watercooling or anything just yet, So how many Megahertz can i knock it up until it becomes unstable 8O Huhahaha, thanks dudez!!

Dunno but you should try it. Remember to check your temps ALWAYS!!!

Not in SLI mode on AIR i manage to get around 30 40mhz more. on water i manage to overclock 150mhz!!!!

I have seen evga factory clock their 7900GTs to 600mhz. The sell them in pairs for sli and call it signature series.

XFX have already done a mild OC on those cards I supose they have voltmoded the PCB to handle it. Try and push it to GTX specs and see.
