If you are going to ignore facts, you might as well back off from technical discussions. I already demonstrated in your prior post how your link was worthless as a benchmark of how fast these cards are in this project. But you are going to ignore that as well too. It is curious that you didn't post your own kernel times, since you have the 7950 right there, but prefer to rely on Bitcoin. Suit yourself. |

Finally got an app_info to run on my 7970. Quadrupled my output. Here's a copy if anyone whats to try it. <app_info> <app> <name>hcc1</name> <user_friendly_name>Help Conquer Cancer</user_friendly_name> </app> <file_info> <name>wcg_hcc1_img_6.56_windows_intelx86__ati_hcc1</name> <executable/> </file_info> <file_info> <name>hcckernel.cl.6.56</name> <executable/> </file_info> <app_version> <app_name>hcc1</app_name> <version_num>656</version_num> <platform>windows_intelx86</platform> <plan_class>ati_hcc1</plan_class> <avg_ncpus>1.0</avg_ncpus> <max_ncpus>1.0</max_ncpus> <coproc> <type>ATI</type> <count>.25</count> </coproc> <file_ref> <file_name>wcg_hcc1_img_6.56_windows_intelx86__ati_hcc1</file_name> <main_program/> </file_ref> <file_ref> <file_name>hcckernel.cl.6.56</file_name> <open_name>hcckernel.cl</open_name> </file_ref> </app_version> </app_info> This will run 4 tasks at a time. Copy and paste into a text document and rename the file app_info.xmll. Shut down boinc, place the file in the WCG project folder and restart boinc. You should be good to go. Guys maybe I should have been more specific. This file is best suited for high end cards like the GTX680 and Radeon7970. Do not attempt to use it if you GPU is running near 95%. If it's lower you can use the file to add more tasks. To do that change the <count>N</count parameter. 1 will run 1 task. 0.50 will run 2. 0.33 wil run 3. 0.25 will run 4. 4 gets my GPU tp 95%. That's enough for me. This will work with any CPu right. Doesn't matter if you have an Intel or amd right? I noticed intel in the script |

You are better off buying a better graphics card and motherboard. My 180$ Sabertooth 990FX has one x16 slot, a x16/8 slot, a x8 slot, and a x4 slot, good enough for three 7970s. It would be far more efficient to get several 7970s, which have an OpenCL SP throughput of well over 4 TFlops, upwards to 5Tflops with a decent overclock, compared to a 7770 with only 1.3 Tflops. Having one strong card is better than having many weak cards. Agreed if: Your computer room can stand the heat from those GPU(s). Your computer has an adequate power supply (PSU). Your computer is big enough inside to allow installing cards that long. I'm having problems with all three of those limits. |

Your thread supports what I stated, so what's your problem? These users also don't seeming to use an app_info.xml file, so you should advise them to do so to improve GPU utilization and maximum work throughput. And yes, you do have that flexibility with a single card, you just don't have that flexibility with low grade cards. I run diablominer and this project at the same time, while also watching 1080p videos with my 7950. The 7950 is supposed to be 3x the cost of a 7770, it is 3x the hardware, your logic doesn't make any sense. You think you can pay less for more? Let's reiterate shall we? HD 7770 = 10 Compute Units. HD 7950 = 32 Compute Units. Part of the extra price for an HD 7950 is for its hardware double precision capability, which the HCC GPU app does not use. I would expect it to be running at a lower clock rate, which makes each of its compute units slower than one for the HD 7770. |

You can tolerate the roaring noise from all the fans running at full sped, providing you don't use water-cooling.  |

ok for some organisational reasons i will buy now a 7950 to get the max out from a single pci2.0 x16 and 300 Euro
----------------------------------------the 4x slot will take the 4850 from another pc still for MW then, because this need not much pcie bandwith and the other PC that hold the 4850 until now, is a quad too, so i can bring a second PC back again to poem with a nvidia card. :) and some more gpu "rochades?" are possible too then :) I will post kernel times then :) (when someone tells me where i can read them ;) |

No, HD 7770 = 68.5 seconds kernel time HD 7950 = 33 seconds kernel time HD 7770 1 task in 2 minutes HD 7970 4 tasks 2 minutes You do the math.

ATI 6870 (1GB) is taking a little over 4 minutes per WU. Hi. ATI 6990 (4Gb) is taking ~2:50 mins per WU. And as card have dual video-core you finally got 2 WU every 3 mins. :) |

I would expect it to be running at a lower clock rate, which makes each of its compute units slower than one for the HD 7770. The 7850 on I would say has Double Precision, considering my 7850 crunches Milkyway@home when the GPU project for this is out of workunits. |

Looking at the specs on AMD, comparing the 7850 and 7950, doesn't show the 7850 as a double precision card. The 7850 is double precision floating point but not double precision compute power.
