In need of some assistance here guys
So I had this 7990 all by itself in a computer that was mining away on scrypt stuff.... doing around 1.4mh/s and really stable for a few months.
I built a new mining rig and now have that 7990 in an open air setup with 3 more 7950s. All my settings are the same for this card as it was in the other computer by itself, but I am now running into 2 issues:
1) The 7990 is only giving me close to 500kh/s per gpu. As you can see I was getting 700kh/s with this card before.
2) It overheats real fast, at least one of the gpus on this card does, the other one is fine temp wise. I lowered the clocks quite a bit and still can't get it to just mine stable without overheating, not to mention the heat issue. This was not a problem before I moved the card.
voltage is 1.1, tc 8192, clocks 850/1000 and 1050/1210 i 13
I have made sure to disable ulps and edit all those values in the registry (win7). I could put this card back in my gaming rig by itself and mine with it but then I would have an extra 7950 not doing anything, so even if I could make it run stable with 500kh/s this would be the better option.
So what am I missing? Is there some extra step to making this run properly when in a rig with different cards that I can't seem to find?
