Can't get over 485 core with 7800gt. Why?

post #1 of 11
Thread Starter 
I've OCed my 7800gt to 485 core, and ran aquamark and went through fine with no artifacts, and checked my temps log with rivatuner, and the temp never went above 50c. When i try and set the core to 490 or above, after i click TEST, it says the test failed. but at 485, it stays really cool. What am i doing wrong?

Thats about the avg for a 7800gt. Unfotunatly its because of a voltage issue. Yuo can volt mod it which yields AMAZING results... but is really risky. A guy with a volt mod was running like 580/1.8 Its insane

Temps are usually not the issue with OC'ing this card it's what the Chip can handle, sometime you get a good chip sometimes you dont.

Yeah Volt Modding will get you a faster card but will also be more susceptible to fry and there's no way you'll be allowed to do a warranty claim.

If it's a temp thing then I'll you know cause I have a NV Silencer probably coming today and I know that'll knock down my temps and we'll see if I can get over 520 but I doubt it

If you can play the stuff you play on High then leave it at 485, it's still not that bad of an OC for that card since I think that was at 430?
