http://www.msi.com/product/mb/Big-Bang-XPower.html#?div=Detail And are there any boards with 8 PCIe slots, where you can actually us eall 8 at the same time? I don't care if all the cards run at 4x or anything like that, they won't be SLI'ed/Xfired. Running linux so in theory the OS should be able to see all 8. I just need to find a board that will fit 8. Kind of like a FASTRA situation (google it), but their board only supported 7 slots, and they had to get a custom BIOS to use all of them.

Sounds like someone is going to be doing some serious bitcoining... You will need PCIe extension ribbons to fit the 6990s into all the slots.

I'd be worried though that the board may not be able to feed so many 6990s.... its 150W per PCIE2.1... thats 1200W going through the board.

yeah i would have serious worries about frying the board with 1200w going into it. I would contact the board maker to verify it can handle 1200w. And the PSU maker to make sure it can take 1200w on the ATX connector, i have seen ATX connectors fry before with alot less than 1200w going into it. You may need to look into soldering on a connector with thicker gauge wires.

What is bitcoining?

And doesn't the power come straight from the PSU for modern video cards, via the molex type connector?

You really have no clue about how power supplies and motherboards work together, do you?

You can hook up one of the biggest, baddest power supply available.....the Silverstone 1500W....to an Atom based mini-ITX board and neither the cpu nor the board would simply burn out from having such a big power supply.

Here's a hint.....no matter how much wattage a power supply is rated to output, it'll only deliver what the computer wants. It's not like the power supply is trying to shove all its rated output all the time and the motherboard is blocking it.

Yeah, what Meghan said is basically what I was asking.

If you're using single slot cards then yes you should be able to pull that off. But you'll need some heavey aireflow for cooling for those cards if the intakes are covered.

you have no idea what the OP was asking do you, he is wanting to run 6+ PCIe video cards. Which can each draw up to 150W from the PCIe slot on the motherboard, and guess what all that power is going through the ATX connector. 6 x 150 = 900w, 8 x 150 = 1200w.

Dont believe me read this post about a user frying his PSU ATX connector with just 3 cards, op is talking about running twice that amount or more, and this was with a top of the line PSU.

I think it would easier to just build two computers with 4 cards in each. Might even fit in a same large case (modded).

Why is having a s*** load of video cards good for this bitcoining that you speak of? Do we now need to replace "but ca it run Crysis?" with "but ca it run bitcoin?"

No, because most cards can run bitcoin, the question is how fast. My 2x6990s make me $40- $60/day... How is your GTX590 doing?

ARE YOU TRYING TO MISLEAD FOLKS INTO THINKING THAT I ONLY HAVE ONE???



j/k, I own a $60 hd 4770

Dam, you got me!!!

But in all honestly 590 is about 6-8 times slower at bit coinmining than 6990 is. No, not because 6990 is a better card, but b/c bitcoing mining is a very vectorized process, which actually uses the 3072 stream processors.
