I have 2 120mm fans on top of the heat sink. 1 fan blowing on the heat pipes as well and to use only 80% fan speed I also have a portable A/C unit blowing cool air. Turning the A/C high cools it right down but it's also noisy. So I keep it in low cool.
I can go higher with my setup. Is like being on water I guess. But I just wanted to hit 900Mhz core. I'll play with it. I bet I can take the voltage down to probably 1.143
Seems I've hit a wall at that speed, any more than those clocks (Tried up to 1125mV) and my card resets its self during Crysis.
I haven't really got round to a decent memory overclock yet, will this eventually display artifacts like a core overclock or simply crash?
To test memory use the first vantage test. You will see artifacts there. You might get 1000Mhz memory on your card. Without any mods that's the max I could do.
Add a couple fans man. You will be able to go higher
I have some fine tuning, but I'm getting close.
Not sure how much higher I can go on air. Still pretty happy though.
Lot better than my 280's, couldnt get more than 100Mhz!
For some reason, my card does not like 1.138 volts.. Its not gettin any hotter than it does when i run vantage with the card at 1.1 volts, but vantage stop in the first or second test.. and I can get my memory above 2215 so far.. Any suggestions would be great..

I need to hurry and order my EK block..
Very nice overclock on the video card and the CPU
I just got a i7 920 and an Asus P6X58D Premium board today. The guy had this running at 4.2Ghz so I know it can do that. I'm just waiting for my other parts and I'll get to really test my GTX 480 in games
Has anyone determined at what point memory starts to become a bottleneck on the 480? I'm sure it varies by application, but is there a point where increasing core clock produces diminishing returns, unless memory rate is also increased from stock levels?
I seem to recall from a thread a while back that overclocking memory produced a huge increase in temps, much more than core. Is that true?

NCSpec should be able to tell us this. I'm also wondering the same. I have gone up to 910 Core and 1070 but it's not much different from 875/1038 core. NC has his card very nicely overclocked on the memory too. His benchmarks numbers are always huge.
