i have 3 6950s unlokced and i run them at 1.2v and i can get to 930 core and if i go to 1.25 i can get to 960 to pull about 410mhs per card. and 900 is still a lot for stock vcore the 6970 runs at 880 stock core at 1.17v so up you v to at least 1.175- 1.2 range (if you temps are lower then 80c) and then try for 900

Yeah. ATM I'm running them both 1175mV 925/625 for ~800mh/s total. With a fanspeed of 70% and an open window, they run at 60'C and 64'C.
Sad thing is, I cannot find that golden ratio between heat and speed when the fan speed is a tad bit lower (60-65%) - either it has to run the same 1175mV voltage and use quite lower clocks (~900mhz) with higher temperature (79'C+), or use near-stock overclock (~845) with stock voltage, which would let me use it bellow 60% fan speed anyway. All I'm trying to figure out, why there's such a gap in fan speed performance, and why it crashes so weirdly when approaching it.
