Well I didn't get the Phoenix miner to go any faster than 120 M/hs. Strange. The good news is that I did download the new poclbm miner and am clocking my 5850 at 850,1000 now to get 325 M/Hs and it not only isn't freezing anymore but is running about 79.5 - 80 degrees now, down from around 82-84. |

It is a common myth that Bitcoin is ruled by a majority of miners. This is not true. Bitcoin miners "vote" on the ordering of transactions, but that's all they do. They can't vote to change the network rules.

120? Are you sure you weren't running another miner at the same time? Are you on Windows. I downloaded the new poclbm also and it runs at 350Mh/s. I'm going to race it side by side with most current snapshot of phoenix and see if there is any diffence in performance. |

I'm going to race it side by side with most current snapshot of phoenix and see if there is any diffence in performance. 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. |

That's crazy. I can't believe that there is that much difference in performance between manufacturers. What's the brand of your card? |

My cards are Asus and Visiontek so I can't say for sure if it's different. The board they are on is 5 years old so I'm sure it's not 2.1, and there's only 1 x16 slot, the other 2 are x8 and x4 and work without a problem. |

Well I didn't get the Phoenix miner to go any faster than 120 M/hs. Post your command line. Here's mine (on Windows. In linux I had to set DEVICE to 1), for a 5850: phoenix -u blahblahblah DEVICE=0 VECTORS AGGRESSION=11 WORKSIZE=128 BFI_INT |

I have adjusted AGRESSION (8 to 13) while having WORKSIZE=64 and WORKSIZE=128 with little effect on the hash rate (and removed the FASTLOOP parameter for AGRESSIONS above 8 after trying them all with the FASTLOOP parameter) I don't know if this is odd or not but if I put an invalid device id it then shows: - AMD Athlont(tm) II x2 245 Processor
