I am sure I wasn't running another miner and that I had the proper device id. I'm on ubuntu 10.10 x64. I seem to have something not quite figured out since the new poclbm instantly gave me 30M/hs more performance but I never found decent settings for phoenix to hardly match half that performance. I also haven't been able to keep from freezing up with memclock under 1000. Obviously I have issue's and am losing out on at least 20 M/hs.
What fglrx packages and SDK are you using?
I found that WORKSIZE slowed my card down with phoenix. It seems to do just fine leaving that option off.
My card didn't like the mem clock below 1000 either. I had to leave it at 1000 until I got AMDOverDriveCtl working.
fglrx 8.801 (fglrx, fglrx-amdcccle, fglrx-modaliases), 2.1 SDK
Thanks for the help here. I do have AMDOverDriveCtl version 1.1.4 but I haven't applied any profile or started using that as of yet.
