How far can I OC my GTX 480 with a 260 for Physx (750w PSU)?

post #1 of 9
Thread Starter 
Hey guys, at the moment, I'm running my GTX 480 by itself. I want to see how far I can OC it before I throw the 260 back in my case. Before I do that, though, I'd like to know what you guys think my limit would be as far as OC potential while my 260 is in my system. The stock (factory OC'ed) clocks for my 480/260 are 820MHz/626MHz core and 1900MHz/1053MHz memory. My CPU is at 3.825GHz.

The primary purpose why I currently only have my GTX 480 in my system is so I can run benchmarks of it with high OC's. If it performs close enough in Physx benchmarks compared to a dedicated 260, then I'll just sell that card off to a friend.

With that being said, would the 260 hinder my 480's OC in games not utilizing Physx? Maybe if I have my 260 in, I can run OC'ed clocks on my 480 while playing games like Just Cause 2, BBC2, or AvP (non-Physx games); but when playing Physx games like Batman: AA, I can just turn down the OC. Will this be possible?

1. Download MSI Afterburner and Furmark
2. OC each clock at a time, Core, Mem, Shader.. And balance Vcore with Frequency...
3. Stress test with Furmark... to see if you have a stable OC....
4. No one can tell you how far u can get your OC... If I had a crystal ball then I could.. ^_^. Its all about testing clocks with voltage and stress testing.. Be patient and see how far you get..

Post back with a screenshot of what you got, ^_^ gl and happy ocing.

You have the Gigabyte Super Overclock version. That card should easily overclock like a beast

Thanks guys, it's just that my main concern was me possibly busting my PSU while testing an OC. I thought if my card didn't have enough juice, then the PSU would die or something. But from what you guys are saying, it seems like it'll be treated just like a regular failed OC and downclock itself.

The PSU will handle both cards just fine, what I would be concerned about would be either card heating up the other more than necessary

OCCT, reports errors on bad overclocks etc.

A good 750 watt PSU shouldn't have trouble with any clock settings on those two.

750w.... lol i ran 2 OCed 480s on one of them....

you will be fine....

also for reference... i ran a 24/7 OC of 800/1600/2100 on the graphics cards

and 4Ghz on the CPU

Well, I guess that settles it then. I won't worry about this stuff any longer - I'll just get to OC'ing now. Thanks guys for all the feedback, I really appreciate it.
