Topic: 6950 Sapphire xtreme - It goes no further 320mhas (Read 1030 times)
maybe it's the software? try downloading the latest? the phatk 3% mod really helps for me in windows 7. it goes from 280-320mh/s to 312-366mh/s If you want more I suggest water cooling & volt-modding.
- Experiment a bit with flag settings, like here:

- Stupid question, but are you saving the settings? go to GPU-Z and check the clocks when GPUs are under load.
- Does it only happen with only all three GPUs connected simultaneously? How does it look with only one GPU connected? Same mhash/s? (if it's higher then there might be a problem with your PSU)
Try to do a google and change the flag setting, it does help quite a bit.
Hi,
I have a rig with a 3 x 6950 sapp xtreme. Running in Ubuntu, phoenix. The PSU is a CoolerMaster SilentPro 700w.
No matter how i overclock or the VGA, it DOES NOT move of 320-325 mhas. I can put it on 800,300 850,300 900,300 and its always the same... any idea ?
EDIT: In fact, is not a problem of the 6950, i change that VGAs for a 3 x 5850, and i cant go further 300 mhas with the 5850s... WTF?
