New to GPU Overclocking

post #1 of 43
Thread Starter 
Alright, since I got my Q6600 stabled at 3.5GHz, I wanted to start learn how to overclock Video Cards. I have never done it so I have no idea.

I am using evga precision tool to do my overclocking.
And I've downloaded FurMark since I heard it was better than ATI tool.
I don't really understand how to tell if it is stable or not using FurMark though.
What are good temperatures to be aware of? I heard GPU could last up to 80C?
And note that I am on stock cooling, but I might hover a fan over it.

Any assistance, steer it toward me.

overclock until the temps. get too high or it artifacts. That's about as much thought as I ever put into it, besides overclocking it slow to let the thermal past set in. If you've had the card for awhile probably not a problem though.

I don't let mine go over 80c. They're fine a bit higher, but I don't like it.

Basically, just keep the core and shader linked for now, then raise them like 10mhz at a time and do a quick test with atitool. Once you get to a balance on all three that you like, you can move to furmark. If it passes furmark, it should be stable. Be careful on overclocking the memory because it can cause weird problems. I just leave mine at 1125 because there's no noticeable difference over that.

But aren't there like stability tests or benchmarks? I don't really understand them. Never been part of this seen.

I run FurMark with the benchmark and by framerates and it finishes. And I also tried the stressing, but I got scared since it went up to like 77C so I closed it..?

I really don't know how to overclock or check for temperatures for GPUs. So you really have to teach me.

What do you mean pass furmark?

Have you raised your fan speed in evga precision? It shouldn't be getting that hot on stock clocks.

And by "pass furmark" I just mean if it can finish furmark without crashing.

Which test though? Stability or Benchmarking?

For Benchmarking which is better time or frame based? If so what parameters?

Yes, I increased the fan now.

And I was using the Xtreme Burning mode, probably that's why it got hot without changing the fan speed.

I usually run the Stability Test at the monitor's native resolution.

What do you mean native resolution? Like what I am using right now? or the maximum?

Native is the same as maximum. I'm guessing yours is 1680x1050?

Not really sure since I'm not using maximum yet.

What if it fails? Does it reset itself to default? Because I just had it failed right now. =(
