My CPU is an AMD Phenom(tm) II X6 1045T Processor So it has 6 cores My video card is a Radeon HD 7970 (powercolor 3gb) I'd like to run the crap out of the video card on HCC Yes Windows 7 64 bit (thanks so much for helping) *I just upgraded my video card driver to 13.1 *I just downloaded and am running boinc 7.0.44 That's almost my setup: X6 1035T, 7950, Win7 64, 7.0.52, 13.2 Beta 6 My 7950 is OC'd to 1000mhz on the engine core. Temp is a near constant 70C. I upgraded from 7.0.44 because my cpu max'd when I switched to 20 concurrent hcc WUs (it seemed to ignore the 80% CPU time I defined). All is fine with 7.0.52. My app config is this: <app_config> <app> <name>hcc1</name> <max_concurrent>20</max_concurrent> <gpu_versions> <gpu_usage>.049</gpu_usage> <- this seems to be a bug. Only 19 ran @ .050 <cpu_usage>.250</cpu_usage> </gpu_versions> </app> </app_config> This seems to be my sweet spot. 5 cores @ 2.6 ghz, 1 gpu @ 1792 Stream Processors. So, if it helps anybody or if anyone has some advice on improvement.. I'm getting about 60 hcc results per hour. I think it takes 3 hours to run a cpu-only hcc WU on this machine. So 180 results in 3 hours instead of 5 = 36x improvement:) **applauds the hcc developers** |

on my hd7870 runing .10 gpu and .495 I am processing 10 wu's in 9.30 to 10.05 averageing 60 per hour on my i52500 oc at 3.60 gpu oc to 1160mhz
----------------------------------------steady at 66c for over a week now.. [Edit 1 times, last edit by Former Member at Feb 25, 2013 1:44:05 PM] |

Re "<gpu_usage>.049</gpu_usage> <- this seems to be a bug. Only 19 ran @ .050"
----------------------------------------Try 0.05 without the ending zero and also 6 decimals .050000 [many BOINC values have a 6 decimal limit] and let me know if it's still running 19 instead of 20. Then I can take it to the developers. And, please confirm client version, ideally this being tested with the latest alpha 7.0.52 release. edit: typo [Edit 1 times, last edit by Former Member at Feb 25, 2013 4:22:27 PM] |

Darned decimals:) Boinc 7.0.52 (x64). Win7. There's nothing denoting it as being an alpha release, but I got it from the Berkley site (unlike some of the alphas I get from a Linux ppa) |

Ya got me beat in price for performance.. For any potential 7950 consumer: Boost seems to limit itself at 65% activity for me and the OC number applies to only the Boost clock speed. I was initially kinda bummed, but now I really like the feature. Just a heads up! |

Understanding that is of course like trying to catch bull at four. |

Understanding that is of course like trying to catch bull at four. Huh?:) I just kinda figured it was the dreaded "diving doubles" precision loss or something similar. I wasn't complaining, just illustrating why it looked odd. It's an easy workaround and hopefully an easy fix.. like x/60D instead of x/60. I've facepalmed more than a few times with that kinda stuff:) |

Does anyone know where I can find a working link for 7.0.44?

32 or 64 bits, what platform? The address for any version you already have is always the same. You only need to change the version number in the link so if you see http://boinc.berkeley.edu/dl/boinc_7.0.28_windows_intelx86.exe on the official download page, change the 28 to 44
----------------------------------------edit: This is the all version download page: http://boinc.berkeley.edu/download_all.php [Edit 1 times, last edit by Former Member at Feb 28, 2013 8:35:42 AM] |
