Open air case and a big boxfan is needed for good temps. Something like this: http://www.stomped.me/pics/100_0253.JPGThat screenshot was taken just a few seconds after launching cgminer, values will get more accurate over time and those rejects came only in the very beginning.

Where did you get the frame that the parts are attached to?

All average out about 700MH/s. They'd run cooler if I could figure out these riser cables. These are all sandwiched on the mobo with a box fan running full tilt. Running anything higher than 1150 is crazy unstable to me, even with only one card in the board running at 70's. ![Huh](https://bitcointalk.org/Smileys/default/huh.gif)

Why do you not lower the memory to 600 Mhz?

I don't think it will actually take anything less than 1000 for memory, it reverts back to 1500 every time for me.
Matched to the clock seems to work best for me.

Did you look into altering the bios?

Of the cards? I guess I could, but would I really see any benefit besides ruining my warranty?

pontiacg5, you're gonna burn up your cards with those temps. Youch! I like to keep the gpu's in my mining rigs lower than 75. I use box fans (they move the most air for mere pennies worth of electricity each day). You can check out my quad 7970 litecoin mining rig build here. Also, I'm assuming you're using risers and spacing out those cards for maximum airflow?

Nice setup! What are those? 7970 or 7950? scrypt or SHA256 mining? No powered risers, right? I have a 4x 7970 system, mining LTC, considering plugging a fifth 7970 in there. PSU is 1500W. Will report back, hope I don't fry the mobo or something...

Fancy seeing you here ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) Nope, no risers. I've got a quad crossfire board so they all fit. That's why the temps are so high, the cards are sandwiched!! Crazy box fan pushing on them all now, but still won't get less than 90c. I tried using 8x to 16x risers, they didn't work. Tried wrapping them in aluminum tape, didn't work. My mobo has external power for the PCIe rails, so I don't think I'd need powered risers but that's all I haven't tried yet. I picked 8x risers because that's what all 4 of my cards run at, 8x. I think 1x might help, maybe?

On my Sapphire 7950's there is a black part right under the two red stripes. This piece is metal, not plastic. When these cards get up to 80 C if you touch the metal piece it will burn you. You will not be able to keep your finger on it for more than 2-3 seconds. 90 C is HOT!

7970s have a 150 difference max between the engine and the memory. So if your engine is at 1150, you can set your memory to 1000, but not 950. At least on the gigabyte 7970s I have using cgminer.
