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.
That HIS won't run at 24000 TC, 1050/1750, I 20, g 1? I have trouble running mine stable at g 2 but those settings get about 685 kH/s and run at about 65 C.
