Ok, bought 12 sapphires, and 3 of everything else. Going to add another mobo and fixing asap. So I will start running 3 rigs with 4 cards each, and will thin them to 4 rigs ASAP.
Noob questions begin here.
1. How do I run the 4 gpus off the mobo listed? Can anyone provide a link to the required extra gear or cables needed. I did upgrade the psu to 1000's already btw

2. How do I clone the harddrives for mining?

3. I got long risers which will space the gpu's no less than 6" apart in a fan like set up, space is not a concern for me. Will this provide adequate cooling space for the 4 gpu on 1 mobo set up in the beginning?

Any tips and suggestions would be great.
Thanks!

iam not sure if 4x 7950 will work stable with a 1000psu. it will depend on the corevoltage of each card.

i got 2x gigabyte7950, this version is overclocked out of the box with a locked corevoltage of 1,25. each card pulls about 320W, so 4x them would be too much for a 1000w psu

Which gigabyte GPU? I'm running 4x gigabyte 7950 windforce, on a 1200W PSU with no problem, I didn't under-volt. They each only pull 200W barely, probably less. How can a 7950 pull 320W? I hope your 7950 better mine at 1000kh or something. Though you are right, 4x7950 on a 1000W most likely will not work, since PSU only work at 80% efficiency. So that 1000W is only capable of giving you 800W actual power, 4x7950 will eat that up, leaving nearly zero power for other components.

my 850w psu pulled 1100 from the wall.

still not burnt out yet, which is good. i'm looking forward for my new psu.

in the mean time, i need to find the most efficient setting.
