As far as I know you can, because you're not using SLI or Crossfire to begin with. You want each card running separately. On Windows this will require monitors or a "VGA Dummy Plug" on each DVI connector.

Then they should both show up in your mining software. I was pretty confused about this at first myself (thank you, Tycho!), but now I've been bitten by the mining bug hard!  Cool

Thanks a bunch! The funny thing is I have already bought a crossfire board to replace my sli one. Guess I'll just build 2 mining rigs ^^

It's easy to get sucked in before you're profitable, so just be careful (unless you have money to burn, then it's just a fun hobby like Folding rigs)! But yeah, I'm waiting on a couple backordered 5850s to complete my third miner now ... and I started in late April Grin

Ye SLI mobo works fine for me, except 2x graphics cards on one mobo is very noisy because the inner card will have huge temperatures. I put the cards to different mobos for now, maybe pci-e raiser thing will solve it.
