OC'ing my 5770

[iviv]

Is it worth it, and how's best to go about it? I've always left graphics cards alone, but I want to get as much prettyness out of DIRT2 as possible, which means I need more power!

Is the best way just to go into the Catalyst and whack the auto-tune feature on and leave it how it's set?

Just out of curiosity, I've stuck ATItool on scanning for artifacts, after 4 minutes at 99% graphics usage its running at 63C, fan at 39%. I can stick the fan up more, I've got an antec900 case so probably won't be able to hear it over the case fans anyway, especially with my headphones on. And its got the stock egg cooler, stock clocks of 850/1200.

Thanks!

yes you can use ccc, and i think it s quite useful, i hav a 4890 and i use msi afterburner even though my card is a sapphire! it allows you to up the voltage without flashin the bios

Thanks for the reply, though I'm not sure if I want to go messing around with graphics card BIOS'es or voltages, I'd rather keep this nice and basic

id leave it at stock then in all honesty if your not using the msi afterburner to overclock with. you wont notice much difference just upping the core, take your mem up to 1250mhz and leave it there

I find auto tune rubbish

all you need to do is set core to 900 and memory to 1300, and you'll be fine

im sure most these cards will do that without any sweat.

Well, with the 10.1 hotfix drivers, I decided to give the auto-tune thing a go. Left it while I ate, and it managed to get up to the max clocks that the CCC would allow (960/1445) without pushing the temp over 60C. Applied, loaded up Dirt 2 to bench, and the PC hung. Restarted to say it had recovered from a bluescreen. Reduced them to 900/1400 and the same thing happened.

I'll try 900/1300 as mentioned in the above post. But I'm guessing that ATI's attempts to stress the card are completely different to how stressed the card gets in gaming?
