I've read a few different posts on recommendations of drivers for ATI on Ubuntu, but I wanted to ask the question again as I haven't found any information around the newer drivers. Part of my problem stems from the fact that I don't see very good MH/s numbers in either Phoenix or cgminer (so I'm guessing it's my setup).
My cards are:
I was just trying to single out the 5870 but was only seeing maybe 20-22MH/s. Cgminer showed a clock rate of 150 I believe, and I tried setting that to 850, but it doesn't seem to like that.
So... Back to square one. Which drivers should I use? I pulled the 12.10 drivers from the ATI site and grabbed the 2.1 SDK. I think, from past experience, if I just use the installer to uninstall the ATI 12.10 drivers it pulls the SDK changes out from the system (correct me if I'm wrong please). I was going to try the 'post-update' drivers that come with Ubuntu 12.04, but Ubuntu likes to not tell you what those actually are or what that means (I suppose I should dig around in apt-cache).
But, what works and what's good for the 5k series of cards? I'm kind of pissed because I had the 5830 in a box from one of those daily deal sites and they "sold" me a 5870, but it's not. Bastards, guess I shouldn't have shelved it for 4 months before opening it up. Whooops...
Anyway, TIA! Seems like the forums are relatively vibrant...
