I have 2 7970's, 1 7950, and 1 280x on a 1200 gold rated psu. It should handle them no problem, I tried upping the voltage, and I tried it in both the config file and in msi afterburner with no luck Sad

and yes, all in 16x slots - two 7970's directly connected to mobo, and the others on 16x-16x risers

Heterogeneous card configurations almost always sacrifice performance. Specifically with 3 different types of cards, you're going to be losing at least some hash rate.

Go with Homogeneous card setups (all the same brand and model, preferably the same batch), if you want to really push your machines to the limit.

I've found after a year that pushing my machines to the limit is less productive than a nice stable continuous hash day after day after day. But maybe I suck at this.

Also, I've had a 7970 running at 95-100 degrees for 3 months now. Just waiting for it to fail I guess (others all run mid 70s to 80s).

Is it running that hot in a case with the others? Why dont you add some more cooling and save it?

They are all in here. Cooling is quite good as the rest run close to 80. I'm sure its a failing card or a card issue. I have it underclocked and undervolted and its still hot. Frankly, I don't really think its a problem but we will see.

Looks like a little closet grow setup.

I learned all my cooling tips and tricks from the grow forums. The inline fan was well rated:)
