2x5970 hardware

I've got 2 5970's on hand (lucky me). Would something like this rig work just swapping the 5850s for 5970s?

Well since this is here, could any 5970 experts help me with stable OC? I'm currently doing 850/300 @ 375 mhash/s, unable to find any stable combinations above 850 core clock. Trying to squeeze more mhash/s out of my 5970s as they are running only around 70 degrees. I believe theres still much OC potential in 'em.

What miner are you using?  And what params?

Mostly the problem is that PSU, as well as cooling.  With two 5970's you'll want a quality 850Watt PSU or better, with at least 70amps on the +12V rails.  If you put those two in right now and loaded it you'd easily exceed the 600 watts since the GPUs alone take 300 watts a piece and your computer has other parts in it.

Ok, so better power supply. I can figure that one out. What can I do on cooling?

As far as miner/parameters the plan is to do whatever maximizes Mhash/s.

I moved with a couple of 120mm fans to help pull air across the cards, made a huge difference and things are running well. As said above the PS is your real issue, especially f you OC since you can get them pulling quite more then stock.
