Hi,
I got a Powercolor 5970 today and decided to try it in mining. I've heard it can get around 800Mh/s, which would be an awesome speed. Currently though, mine are getting a combined hashrate of around 510MH/s @ 825MHz on the core clock, and 500MHz on the memory clock. (lowest memory clock can go)
I have Everything installed driverwise as 12.10, except for CCC, which is 12.8. I couldn't get it working unless I used these versions. How do these numbers look to you for this card? Kind of low? I'm currently using GUIMiner with 2 cores dedicated to each GPU on a 3570k.
