I got it working, but when I try to overclock, it crashes. Got the cards up to 730khs each, but I think I need more ram in order to OC more. Does that sound right?

Unless you watercool them, 730 could be too much

Three of my 7970's are running at 746,788,788 all on air and temps are 68,72 and 74. Mind you I have another 7970 that will not go over 550 no matter what. For what is is worth my two 290x's run at 880 each and temps are in the high 70's on air. 6 cards spread out over 3 systems all in cases. Two with sides off, of those one has a small house fan pointed at it (ambient temp around 73c) the other is in the garage.

My 290x's are also in a case with the side on it in my lounge, again ambient temps are around 73c.

what settings are you using and clocks i can run 1050/1766 to get 720 out of my 7970s or if i run 1170/1950 i get 830 out of one of my 7970s not the other it cant run that high both mine are under water tho.

The two 7970's running at 788= 1130 core / 1745 mem, I 13, G 2, 8192 tc. Brand is XFX on these.

The one 7970 running at 746= 1070 core / 1690 mem, I 13, G 2, 8192 tc. Brand is HIS

The lame 7970 running at 540= 1050 / 1500, I 13, G 1 (will not run at g2) 8192 tc. Brand is HIS

The two 290x's running at 880= 900 core / 1495 mem, I 20 , G 1, 32765 tc. Brand is XFX on these.
