I'll just repost here from another thread.
I am happy to report that with Cat 9.1 I can clearly fold on both cores on Radeon 4870X2 under Vista x64 SP1. I have never managed to do that before. No need for any trick either, no need to connect the second output, extend desktop etc. Also note that I removed any ATI dlls from folding folder to use system supplied dlls.
Also about the second GPU frequencies for folding.
I have adopted the simple solution, just create catalyst profile and edit it manually setting values for both cores. I fold at 795x300 for both cores, because looks like memory speed contributes greatly to temperature but not to performance. I have got stable folding on both cores 795x300 with temperatures 85 and 70 for the first and the second cores respectively with fan rotating at only 38% fixed so noise is tolerable.
Hope that helps someone.

Enjoy the new points...

The day that I finally buy a 9800GX2.

Damn.

But really good for the Team Red dual Gpu folders!

You are still better off with the GX2 for Folding, at least until the bigger WU's arrive. This from the same thread;

omg it works! And performance is crazy!

Fahmon showing 6690 total PDD (4870x2, q6660@ 3.2, x48 mb, 4gb ram, vista x64)

)) I am very happy that i'll contribute more to scientists.

Not quite up to the GX2 yet, but it's better than wasting half your card...

We'll see about that next week, once the card, board, Ram and Quad arrive... and add a 9800GT to the mix!

Dedicated Folding rig.

Knew it was just a matter of when, glad you're back at it...

When you're unemployed, you have to prioritize. But once cash started to flow again, the Wife said it was time for me to rebuild my rigs.

Done Honey!

Lucky you have a very understanding wife, the withdrawal symptoms must have been quite obvious...

It's my hobby, and she understands there is a price tagged to those components. Luckly, I can sell most of those parts with a profit.

But doing so I don't get to play with them anymore, and enjoy my hobby.

Yes, I'm back in Folding. The i7 rig will stay dedicated to Rosetta, but this new rig will (probably) be based on Ubuntu, with dual SMP Clients, and triple GPU Clients...

If you're going to jump back in you might as well make a big splash.

The native linux SMP client is supposed to make almost double the PPD thanks to the SMP2 core, can't wait for that to trickle down to windoze, either that or convert one of my rigs (or get another, ouch$)

I'll let you know how the ppd looks like. I've heard - read the same thing. And since I'll be building this one from scratch, I'll install a native Linux distro first, probably Ubuntu.
