So I'm just tinkering about, I downloaded EVGA Precision and was wondering how far to clock my GPU and in what steps I should clock. Currently thus GT 240 Core - 550 Mhz Shader - 1340 Mhz Memory - 790 Mhz. Any suggestions? Many thanks Zinf
buy a new card ? GT 240 is very underpowered and any overclock you make will have very little effect on your frames to be honest probly less than 10% and even thats optimistic
Overclock until it becomes unstable, and then back down a little? Gains from GPU overclocking tend to be marginal at best (exclude your GTX460/HD5850/whatever your favorite card is, I'm not flaming) so there's not much point bothering in it anyways. Not sure if I understand the question. Furmark is your friend.
I only bought it yesterday . It's a long story but I'm just messing around before a new build so just testing it out.
Generally, with any day-to-day overclock, what you'd ideally want to be doing is finding the highest point of stability, and then backing down from there a bit, rather than getting to the highest stable point. You'll sometimes find that your overclock is stable for most games, but there could be one game which is particularly intensive which will knock your overclock off it's feet (I found this with Crysis, for example). This is all because, as SlowMotionSuicide said, GPU overclocks don't yield huge performance increases that often, and with so many pre-overclocked cards out there, the point of instability is often much earlier than you might think. I'd also use games for stability testing, rather than benchmarks.
Cards like the HD 5970 can gain 15fps from massive overclocks to 1GHz. Takes it from 5850 crossfire performance to over 5870 crossfire performance. However, without voltage tweaking, you can't do much with graphics cards.
