There wasn't a difference in hashing speed on either windows or linux for me, but using cgminer should help quite a bit. I think the diablo or phatk kernel is best (it is for me anyway). I like your case
Cool, I'll give it a try. Doesn't look too terribly complicated.
Thanks!
Thanks!
I'm assuming you spaced yours apart with riser cables right? Are you using the powered version? My motherboard has a sata plug that supposedly adds extra power to the pci-e bus. Won't even boot without it if you've got more than three cards in there. If I wanted to upgrade to a few extra cards would you recommend the powered versions? I wanted to try and run them all on the mobo, but since that isn't possible I might as well add more haha
Are you running the reference clock? If not what sort of clock are you running to get that hashrate? I'd be a bit dissapointed to learn that you were able to generate the same average per card hashrate as I do at a slower clock lol. I might just return these ghz editions and switch to reference cards.
Would I see a gain in hashrate moving to Linux? I assume that the gui kinda takes away from efficiency a bit, right?
Thanks for the post Mccminer!

Not sure about Linux, but I know that you would get a benefit from moving to CGminer.

You should end up pretty close to 3Gh/s. I'm running a similar configuration with (5) Gigabyte 7970's (non-GHz editions), and I'm conservatively averaging about 3.4Gh/s. I cranked the settings on up, and it ran faster, but wasn't stable. I didn't like waking up in the morning and finding out that I hadn't been mining for 10+ hours because everything locked up! 
Just for comparisons sake, my setup is running Linux and cgminer.

Hey everyone, I just finished building my first mining rig, thought I'd post it up here and see what you all think
How it started...
I didn't take pictures of bending it up. Press brakes are pretty damn intimidating, no distractions lol
Testing for fitment!
I managed to get everything right the first time around!
The components...
Gigabyte G1.Sniper 3 board. Z77, 1155. Gotta love all the pcie bandwidth!
Intel i3 3220. Probably overkill, but I want to use this for other things occasionally too.
16GB of some off brand 1600 ram
and
4 gigabyte 7970 Ghz editions
Testing out the nut riveter and standoffs.
The power supply, 1300W. Lots and lots of PCI-e plugs!
Dang, that's gonna be hard to keep cool....
My "idea" of a solution...
Cable ties, built in so I can lightly pull the cards apart.
Fan grilles in a few choice spots to keep cables away from fans. I split the chassis fan headers to power all these fans, this board only had 4.
Oh, and a couple of baby resistors to make it all go. Anyone familiar with GM's early vats lol
I hate these stupid intel fans. I've built at least 6 machines with these heatsinks and I've never been able to reliably use the built in wire ties!
This thing is a gigantic piece of crap. Unfortunately my ol' trusty Maxtor died on me
And finally, a little results...
Damn!! Too much heat, not enough room to get rid of it! Three of the 4 are throttling at around 95-97 degrees. The one on the end manages to get 630-640 at stock clocks, -v -w128 in guiminer.
And with a bit of clocking... I can't get any higher than 1175 stable right now. At those clocks I'm averaging around 680. I'm hoping for a little more when I get these spaced out and cooled down a little.
So, my new plan of attack is going to be spacing these cards out. I've ordered 4 8x to 16x cable risers, 8x because that's all the bandwidth my processor has for each. I know I don't need any more than 1x for mining, but I want to use it for other things too haha.
Even crippled up she's still averaging around 1900 MH/s. I've got the top three cards severely underclocked right now. Any recommendations to increase that are greatly appreciated haha
Stay tuned, interesting things happening when the risers decide to show up
I just realized that the lights are flickering in my living room because of this beast! Good thing it's going to run in a machine shop, free power!
