I sli'd the 580's, as long as you have about 1 slot of open space between the two cards you're set. I had mine directly underneath eachother at the beginning and my top card would get extremely high temperatures and the fan would jump to 100% at times.

After moving the bottom card 1 slot down they both run with about 5 degrees difference (idle: 35 - load: 65).

One can also remove the shroud off the top card if both cards have to sit close.

For anyone experiencing very high temperatures on these cards...

Firstly, I'm going to state that the following is merely my opinion, which I am basing on my own personal experience with the Direct CU II.

In my opinion, there is too much weight hanging on those 4 springs, and I believe the springs aren't strong enough to maintain full contact between the GPU and the sink.

I purchased my first 6950 a few months ago, and when I first installed it the temperature was rising very rapidly and reaching around 92 deg C within 15 seconds of starting Furmark. I knew this couldn't be right, so I ran Furmark for a second time, and this time, while it was running, I got a hold of the heat pipes at the end of the card, to see if it felt as hot as it was reporting. As I took hold of one of the heat pipes, I noticed that the rate at which the temperature was rising, slowed quite considerably, and maxed out at 84 deg, as opposed to the previous reading of 92 deg.

I had a quick eureka moment... I removed the card, wrapped a few cable ties around (just where the shroud narrows) to take some of the weight, tightened the cable ties a little and reinstalled the card. The difference was amazing, the card now reached 76 deg C max, and lapping the sink brought this down to around 70 deg.

It's my opinion that hanging the weight of the cooler, shroud and fans from those 4 little springs (it's mostly hanging from 2 springs really, the other 2 are acting as a fulcrum), is the reason these cards are overheating. I think the weight is pulling the sink away from the GPU, so If you have one of these and it's getting hot, wrap a few cable ties around the centre of the card, to suspend the weight of the heat sink, then see how your temps are.

Like I say, this is only my opinion, and there may be nothing wrong with the design of the cards, but give it a try.

Are your RAM modules in the correct channels?

Also.... If you're planning on overclocking your rig, you should probably use an 8 pin EATX connector instead of a 4 pin.

The RAMs were in single channel when I took the photo.

Also, why should I use a 8pin one instead of the 6?please explain. it overclocks just fine, I hit a stable 1000mhz with it. It is a bit hotter than usual though, but on stock clocks too. Nevermind, I've just read your post.

Edit: I might try the stuff with the cable ties. But wouldn't it break, or curve the PCB?

There's a metal bar down the front side of the PCB on my 6950.
