My Sapphire Vapor X 7970s were running too hot. I had to shut down one of them because it was going up to 95c. It runs okay with two of them around 85c each but its still unstable.
How do you keep them cool? I'm getting around 666-700khash each.
Hmmm, you used all those voltage settings yeah? and fans on auto?
And you've flashed the BIOS? And using all the settings i put on the other thread, and setting max allocation gpu..?
If the answer is yes to all of those, then i am very confused why your temps are so hot and hash rate is so low.
Also don't forget you may need to adjust your GPU speed slightly as all GPU's are different (apparently).
Could you post a picture of your mining rig?
Yeah will do when i get a chance
