Hi, I had a problem with a 6950 I just added to my collection... LOL when I did the over clocking unlcok thing everything would go to 0 and not save the new clock speeds I put in. I am using afterburner.

I have the same card and it seems to be stable at 880/625. I get 358Mh/s per card with cgminer 1.5.1. I am using MSI afterburner for the overclock/underclock. |

MSI Afterburner refused to over/underclock my MSI TFII 6950, I had to use a utility that edited some registry values directly to unlock the ranges.
I've got the card OC'd to 900 core, 500 memory and am grinding 400 MH/s using Phoenix 1.6.2/phatk, 90% fan, 66 deg. C.
I'm actually running via GuiMiner with the following extra flags:
-k phatk VECTORS BFI_INT WORKSIZE=128 AGGRESSION=13 FASTLOOP=false
Oh, almost forgot to mention - I have also unlocked the extra shaders, I have 1536 total shaders.

You should get about 370 MHs @ 900 Mhz. The fastest fix might be to try another OC application. Trixx is probably your next best bet. Also, clocktweak is worth a look.

I disagree. See screenshot.  |

you can get 400 mh/s outta it but prob more stable at about 370-380. Make sure you go into CCC and move the powertune slider to +20% or the card will throttle.

Does that mean I can get 430 MH/s if I powertune +20%?!   I found the card got too hot when I tried that. I may later on though when I can cool it bit better. |

I disagree. See screenshot. Your Mh/s will also differ depending on how many cards you are running on a single MB. I run 5 of these per MB and there is no stability at 900/500. I have to back off to 880/500 to keep things stable. |
