Anyone notice with 12.6 WHQL slave cards don't clock down correctly? My 2nd card sits at 500MHz. Happens with 12.7 beta as well lol.

p-states are like the final boss for the AMD driver team. Back to good old RC11, I swear I'll be using it in 6 months time

Who cares if the second card sits at 500MHz? Not a big deal IMO...

Besides, I'm running 12.6 WHQL and my slave card is at 300MHz at idle...

Because its the difference between idling at 30c and 50c. It seems to go back to proper idle if I open and close a 3D app though. It just blows my mind that they still have this problem when replicating it is as easy as sticking more than one 7970 in a computer and turning it on

Yup. Still got it. I just run Furmark quickly and shut if off again. I use hibernate on my rig when I'm not using it, and the clock issue crops up even after coming out of hibernation. Does 12.7 fix this? And does anyone have GPUZ locking up the system with 12.6 WHQL?

12.6 beta, 12.6 whql and 12.7 beta all have the problem. I didnt experience a GPUZ crash though. I'll stay with RC11 until 12.7 whql or whatever the next release is and give that a try

I have personally disabled flash video acceleration, it's too problematic.

how do you do this?

Is it just going to ie 9 tools - advanced area - uncheck the GPU acceleration box?

How either card overclocks, ie max clocks is independent of the asic %. Disregarding the individual overclocking, 65% is better because it will actually be able to run more voltage. Ideal card imo is 73%, right square in the middle at 1.175. That said 65% is closer to ideal for LN2 duty than water.

Sup guys. Picked up a MSI TF3 7950.
Read about ASIC quality here in this thread. Intrigued me. So checked out my card. 86.4%
Prompted me to try out some overclocking.

Core: 1000Mhz
Mem: 1574Mhz

Is where I am at. Yea, you could say its the max from default sliders in CCC software, but I did slowly bump Core till I hit 1k, the backed down to stock 880, then brought up Mem till 1575. Then both up.
So far so good. Ran MSI Kombuster 1920x1080 8x MSAA for 2hrs just fine. Max temp of 72* and running a fairly linear fan profile. Stays nice n quiet.

Overall, love this card much better than my old 4890s in xfire. Mainly because under any load it doesnt sound like I have twin jet engines running.
