Just got my highest Fire Strike gpu score - http://www.3dmark.com/3dm/12831726? - 13830

Currently using 1355/2050 with 15mv undervolt @ 50% power level.

Do you have the histogram of the clocks while you run 3dmark?

I've had gpu-z logging everything thus far.

First clocks I used were the cards default - 1328/2050 and got this score with a 10% power increase and 25mv underclock - 12672 - http://www.3dmark.com/fs/9047245

then I ran these at the same clock speeds with a 10% power level increase each time

20% - http://www.3dmark.com/fs/9048719
30% - http://www.3dmark.com/fs/9048588
40% - http://www.3dmark.com/fs/9048650
50% - http://www.3dmark.com/fs/9048859

Then my most recent scores were all at 1355/2050 with a 15mv underclock

Ultra - http://www.3dmark.com/fs/9053231
Extreme - http://www.3dmark.com/fs/9053170
Fire Strike - http://www.3dmark.com/fs/9053506

From the last score it seems that it's throttling a bit.

I'm still trying to find the sweetspot for the card and the voltage settings. It performs better with either 20% or 50% power levels, and with a slight undervolt. Undervolt too far, and the drivers crash. It's a balancing act. I think I may be near the limit for this card in its current state with out any modifications (different cooler, bios, drivers, etc) however, my temps have never gotten above 74c

74C are kinda high for overclocling GloFo node and GCN
