Yes, but if you're new to Linux, I'd say try Linux Mint (http://www.linuxmint.com/download.php) first. Grab the Cinnamon, 64-bit image.

Cheers, will grab that later. I put Ubuntu on earlier via a windows install....no idea what Im doing. I was stumped at installing the catalyst driver. Much reading to do.

it looks like someone already posted the right settings, but you can also use my thread

Well, I'm still not really happy. People seem to be routinely getting 400+kh/s with 6950's without much difficulty. I can't get any higher than ~315 per card, and not really any idea why. Over clocking didnt make much difference. Too top it off one of my cards (gigabyte HD6950, reference board i think) runs super hot so it crashes easily. The other is a Sapphire HD6950 Dirt3 edition, much better cooling but it wont unlock the shaders after flashing. I'm just not having much luck.

At the moment it seems I'll have to accept 630kh/s is the most I will get out of the cards. Thanks for the link, I've been there earlier today, it did help quite a lot.

Have you tried unlocking to 6970 shaders? I get 460 k/hash easily with my unlocked MSI 6950. Core clock 850 mhz.

Yeah, I managed to unlock the extra shaders on my Gigabyte card, but it seemed to negatively effect the hash rate by about 10%. I've read that sometimes the extra shaders just aren't very good. Perhaps this is one of those cards that didn't quite make it as a 6970.

Gah, what a frustrating day. Girlfriend is pissed at me for sitting in front of the computer all day
