I'm not following this, it has 6 slots yes but 5 of them are x1 slots, is this irrelevant to mining somehow?

As said above, you use powered risers. :)


Great value on that board!


I love that picture. :p although I certainly wouldn't be using GPUs for BTC. Join the OcUK mining pool and go WDC > BTC :D

Now need ocuk to stock the powered 1x to 16x risers, some 16x to 16x cables and the socket 1150 celerons :-)

Odd everywhere is now getting these boards in. My local shop just got 5 in at £50 though. Sorry ocuk, got one yesterday :-( As much as i love ocuk prices/deals/kit
 
Could someone explain why the bandwidth is unimportant if it's utilising the GPUs please? Is it because it uses the GPUs computational power rather than transferring huge image buffers?
 
Good analogy lifted from reddit ;

"In mining, you don't need back and forth throughput. You give the GPU a small chunk of data, and it grinds away on it for a long time, and then returns a small result. Rinse and repeat.

Analogy: If a factory is churning out a million widgets a week, there's a lot of trucks of materials in, and a lot of trucks of product out. That's how a GPU works doing graphics stuff. This is like a factory that turns out one small but really labor intensive widget a week. Like a fancy watch. Not much material in, and you can ship the result out in an envelope."

And some pictures of the rig being used : http://imgur.com/a/IISox#OeXLhKn

Its using a PCI-E x1 to x16 adapter that uses USB cables for the transfer, and a sata extension to provide power to the external 16x slot. (can be found on a certain bay of electronics for around £10-20 each). However cheaper ribbon cables can be found for much less.

Gives you an idea on what a working rig would look like.

I knew that would happen, I got mine delivered Tuesday this week, although I am now waiting for the 280's to start showing some stock, so I can complete my build.
 
More arriving in stock tomorrow, I've got some back orders and demand is high but we should have some free stock for a day or two so don't dawdle :D
