I'm selling this because I do not have anywhere to put it in my office. I still have not open up or setup the machine, it's impossible to carry this thing up many flight of stairs.

What is a good setting for SAPPHIRE Radeon HD 7970 GPU?
I'm currently getting only 650Mh/s with this card (http://www.newegg.com/Product/Product.aspx?Item=N82E16814202008) with cgminer.
Can this card go up to 700-750Mh/s?

Nice job! Are the big fans blowing downwards? Maybe you want them to suck air upwards, in the normal direction the heat would go. That could optimize airflow and temperatures.
Thanks for the feedback Sophokles!! I've put it on the side now so it'll blow hot air out the window.
(4) x16 -> x16 + (2) x1 -> x16 extenders riser/cables for sale
x16 -> x16 = I have 4 in stock
x1 -> x16 w/molex = I have 1 in stock
x1 -> x16 = I have 1 in stock
I've bought too many of these for my rig, and I no longer need it.
I will ship this from California to anywhere in the US only.
Make me an offer.
I will accept BTC

There you go. This is the stable configuration with 4 cards. There is a bit of space between the cards and the PSU, so I'm currently fitting a fifth one in there

It's awesome!!
Where did you get the hardware for that open air rig?
You don't need special configuration, just plug in the risers. But not all combinations of PCIe slots work. Was a bit of trial and error until all cards got recognized.
OS is Win 7.
Will post some pictures later!

Thanks Sophokles!
I have 2 x standard Gigabyte 7970, etc and can get 750K/hash per card at 80-85C temps. I lower it to 718k/hash to keep temps below 79C
what is your setting? I can only get it to go up 700kh/s without crashing.
Thanks
I have this motherboard = GIGABYTE GA-990FXA-UD5

You will need a powered riser for at least the fourth card, I would suggest at least two just to be safe, though. 7970's are power hungry.
Actually, I have the exactly the same setup (mobo and cards) running with 4 cards, without powered risers. Has been running stable for weeks (mining litecoin), no problem so far. I have just mailed Gigabyte customer support if its ok to plug in a fifth card... We keep you posted about the results, hehe.
Do you have a picture to share with all of us
With 4 cards do you have to do any kind of special configuration? or just plug it into the motherboard with the riser cable?
What OS are you running?
