Overclocking a 580

post #1 of 5
Thread Starter 
So I've had my EVGA 580 for a few months now and I really haven't touched overclocking much. I have it right now sitting only at 820Mhz and have had it up to 850Mhz, and was just curious as how high I can get this thing while keeping temps in check. I'm on air, but I'm using a Silverstone FT02 so the motherboard is rotated 90 degrees and it blows the air out upward which is very efficient. Furthermore, I have afterburner installed and was wondering what else I would need to install/do to start getting this 580 to it's peak performance.

Thanks

Just msi AB is fine to overclock.
Just put the volts at a around the 1.1v, and start upping the clocks until its either too hot (and than lower the volt) or you heat the OC wall. Add a bit of volt and repeat until sadisfied.
To test stability mostly just play a game, or run 3dmark benchmarks a few times.

Mine personally:

875 / 1750 / 2200 @ 1.10v
900 / 1800 / 2200 @ 1.15v

Your results may vary. Temperatures get very warm at 1.15v. 1.10v it ran perfectly fine with the stock fan profile though. At my 900 core speed with more voltage though, I forced 85% fan speed on, just to be safe.

So yeah, just increase voltage, increase core clock...test and repeat. You'll know if its unstable. And if it is, restart your computer (needed to make it work right again), and try again.

Sounds good, I'll start testing here shortly and post up what I'm getting.

Thanks

Just make sure you don't go overboard and try to keep the cards are mid 70s temp imo.

You might go higher, but the higher the cards, the less stable the overclock will be. Also on a pretty hot day, you might suddenly see your cards running at 80+ easily while gaming.

So as long as you can keep your cards in check, make sure they are as stable as you can.
