That annoying display driver crap is Windows fault. What happens is the new video stack in Windows Vista/Seven runs seperate from the kernel so that video driver restarts are possible without a full reboot. Thus preventing many video related BSOD's. My HD7770 under Ubu12.10 locks up the UI occasionally. Any one knows what is the Ubuntu counterpart of the WIndows 'driver timemout'?; ; andzgridPost#793 ; |

Sorry I am unaware of a similar driver timeout in Linux. Anyone else know if there is anything similar?
Thanks, armstrdj |

Hi there!!
----------------------------------------THANK you for your list!!! http://www.worldcommunitygrid.org/forums/wcg/viewpostinthread?post=396619 I want to add A GPU card to an existing PC. (It is an HP Pavilion a6720f) The PC is (from BOINC Info):Processor: 4 AuthenticAMD AMD Phenom(tm) 9550 Quad-Core Processor [Family 16 Model 2 Stepping 3] How do I tell if the existing power supply can handle it? How can I tell if the existing Fan/cooling is enough? I have a 900VA UPS. Is that enough? Egad? A lot of questions Where do I start? Thanks!!

I think that first you need to find all the information you can about the power supply fitted to your machine. (perhaps from the attached label???)
----------------------------------------Of particular interest is the total watts (or amps) that the 12v rail(s) are capable of. Running HCC on GPU does not fully load the GPU to the extent that the manufacturer has designed for so MAYBE, just maybe, you will be able to run a card even on a less capable psu. Ultimately, provided that your HP does not use some proprietary form factor for its PSU, you could replace it.  [Edit 1 times, last edit by OldChap at Jan 10, 2013 9:28:54 PM] |

----------------------------------------300 watt PSU. You might be able to put a HD6670 on it, but you probably won't be able to get a fancier card like the HD7000 series or any of the better 6000 series card on it. If you want to check how much your wattage your system will require: http://images10.newegg.com/BizIntell/tool/psu...Supply-Wattage-Calculator  |

Well, I finally got around to tuning the 2P 8-core 32-thread Xeon rig. I set it run 16 threads per 7950 card and it looks like it's buzzing through them in 13-17 minutes so I guess we'll call that an average of 15 minutes.
----------------------------------------So if I'm doing my math right, that's 4 wu's per core per hour for about 3072 wu's per day. I don't know if those are single or double though but I guess in theory that could be as high as 6k+ single wu's. I think I still have some room to oc the cards. Right now the clocks are only set to 980mhz and the memory speed to 1310mhz. I'm pretty sure I can get the clocks up to 1k+ though, but I'll leave it like this until I upgrade to the beta drivers.   |

There is no advantage in tuning the graphics memory.
----------------------------------------Not sure what you can do in terms of MB tuning but at least have turbo on and if you can run stable with a small bclk boost that would help. Memory tuning? Some 7950's can do over 1200 if you can keep them cool. If you are lucky in the GPU overclocking lottery I think you may get each card to do >75 wu's an hour |

Hi all,
I am looking into grabbing a HCC compatible GPU for my 24/7 cruncher in the basement but need to be economical about it to keep total costs down. I'm looking a slew of 5000 series ATI cards that are in my price range but was curious to know what specs I should be looking at to get the most out of the purchase. I.e. # of stream processors > effective core clock > available memory. Also, seems like ATI may be a questionable tech since it sounds like nVidia seems to be the more popular go-to. I've only read the first 7 pages in this forum, did WCG ever lean one way or the other on which tech is most likely to be used in the future? Thanks G |
