This question already has an answer here:
I'm going to make my own mining rig for bitcoins. I have a friend who's going to build me a custom casing for it so it will be open air. Now what I want to know is how many GPUs can be crammed onto one motherboard such as this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16813157262 Additionally, I'm looking maybe for an alternative to this motherboard to put 5870s in bulk.(Socket could be anything really, AMD only as they have cheap CPUs though)
I currently have a 5850 in my everyday computer which I use for mining, it's clocked at 950mhz core clock up from 725mhz and the memory is at 350mhz down from 1000mhz.
That being said, I would be looking for putting 6 5870s total, each clocked at 1100mhz up from 850mhz and memory at 160mhz down from 1200mhz.
what kind of PSU would be able to handle all of that? (No hard drive, just a flash drive)
Also what PCIe slots can we plug in risers to?3
Thank you for your time and answers.
