Wow!  Thanks for the great info everyone!

Does anyone know if this motherboard:

Quote
Motherboard: MSI 790FX GD70, but any 4xPCI-E AMD that allows 4 dual-slot GPUs to fit works - $185
Some alternatives are the newer MSI 890FX GD70 (more expensive, easier to find) and the much older MSI K9A2 Platinum. (very hard to find)

would be capable of supporting 4x 6990's down the road should I want to upgrade?

Thanks!

Yes it should, and that's the route I'm going as well. However, you're going to need some kind of custom case setup for 4x 6990's in one system due to the power requirements.

Or no case at all. Mrb has blogged about 4 5970s on one board, with some "interesting" cooling... I assume that anything a 5970 (or four) can do, a 6990 can do as well.

It's possible to fit 4x 6990 in that motherboard, but cooling those cards is another matter entirely. Without something like PCI-E extenders there is no way that 375W cards are going to be able to function with highly restricted airflow.

Wow, nice setup jedi!  You must've had a heck of a deal on those 5780's to get four of them, and a complete build, under $1070.  Also, you're getting more MH/s than any of the listings on the wiki... is the wiki just horribly outdated?  Anyone want to update it?

I think the wiki page is outdated, since there has been a large speed increase lately thanks to BFI_INT enabled miners.

Nice monitoring page, it's much better than the one I threw together!  Are you planning on open-sourcing it?

Nice, maybe add wattage used too to calculate electricity costs.

That's a lot harder to do since wattage can't be obtained from internal sensors like temperature can. It's also meaningless for me since I don't pay for electricity.

I'm running a single 5870 right now (on poclbm not overclocked) and I'm only getting 290mhash out of it.  Jedi95 can you or someone please tell me how to get it up to the speeds listed at this site?

You are probably using an older version of poclbm that doesn't have BFI_INT support. I also have the cards overclocked to the highest I could get on stock voltage. (930-1020MHz)

You can either update to the latest poclbm or try Phoenix: (developed by CFSworks and myself)
