5970 Mhash/s ?

How many Mhash/s should i get with an ATi HD5970 running at standard clock (725/1000) ??

Im currently using the GUIMiner v2011-08-24.

Around 660 MH/s with cgminer or bitminter I think. There is absolutely no point running the card at 1000 MHz memory though. Clock it as low as it will go, it wont hurt performance (in fact, it may marginally increase performance) and it will save you a fair bit of heat/electricity.

Im only getting 220 Mhash/s pr. GPU - so a total of 440 Mhash/s.

Is that because of the miner im using?

Possibly. Although if you are using the latest AMD drivers (11.12), that also doesnt help. Try bitminter, see my signature. Its easy to use and among the fastest for radeon 5xx0 cards. You can also try cgminer, but its a bit more hassle to set up.

BitMinter is running at a total of 572 Mhash/s, so a good 120 Mhash/s more than GUIMiner!

I would suggest over clocking to 830 MHz @ 1000 or less mem clock.  Im geting about 720 MH/s @ 68 C in a linux rig with a Macgyvered card.  I took of the shroud spread out the heatsink fins w/ needle nose pliers and zip-tied 2 120 mm fans to it.
