Looks fine to me, as long as it is stable at that voltage. I think my 7990 was a crappy clocker so i left it at stock and focused on getting the voltage down. Managed to get it operating at 80-85c per core per game in relative silence.

Looks low to me.
Yep. I recommend leaving the gpu at stock clocks initially. Set 1000/1500 and use voltage 1.150v. Play games for a couple of hours. No crashes? Start lowering voltage in 12v increments until you hit instability. Then back off 6-12v. Once you know your base, then expand and start clocking. That's how i do it.
it's starting ok at 1.152, but was very twitchy at 1.13, so there aint a lot that you can do with it............ i may as well leave it at default 1.2..........no lets make it 1.175
because this mobo is a bit twitchy at the best of times, let along the GPU adding to my woes !
lets hope the next AMD Dual card is more fun than this, because this 7990 is a bit of a bore

No, find the lowest possible stable voltage, then move it up one notch. Every little counts with a card like this. Come on Mal, nurture it.
Mal stop using Kombuster right now. Use Unigine Heaven to test stability at max settings. Once you get stability in Heaven up voltage another notch or two and play some games. Demanding DX11 games are the best stability test.

Voltage back to 1.2v Mal, work your way down in 12v increments.
That on stock clocks? Wow you must have a stinker. Try 1.191v.
no the clocks are on maximum, as above !
power limit = +10
core clock = 1100
memory= 1575
the fan does not increase in rpm either
Ah, that's ok then. Whack voltage up a notch or two, might be close to full stability now.
