    MW: 2 WUs when in Crossfire?

    For some reason I thought that when in crossfire, the two GPUs would crunch together on a single WU. In MW on Kat's rig with the new HD4870's from Shadow in CrossFire, MW is crunching 2 WUs, a single one on each card.
    Is this normal? Thanks!

    Yes. BOINC still sees them as separate GPUs.

    Depends on the project. DNET/Moo will use both cards on the same WU. MW crunches a WU on each GPU.

    OK, thanks guys. Looks like all is working well, then. Half the day gone and she is at 75K for MW today. I might have to O/C these 4870's a little more.

    Crossfire (or not) is invisible to BOINC. One project app (moo/dnetc) will run on all GPUs, like AQUA does on CPUs. The rest treat GPUs individually, CF or not.

    If was a sound device I would tell you all, for me it seems just like a computer I will take the oportunity to ask gently. WOULD YOU PLEASE SPEAK ENGLISH. 386 sx is a kind of motorcicle?

    Duke the best at not knowing about computers

    If you have a good question about computers do it to me the answer will be always the same. I JUST DONT KNOW

    I have a GPU to put on my computer makes now 2 months. I am still watching it. But paying a lot of attencion.

    I think this HD5450 has no chance and the other that is in the box the HD5870 is so beatifull one day I will marry it. I will go to that priest perhaps he will do the marriage.

    Have you had much luck running MOO with multiple GPUs in a single system? You may have posted this in another thread but if you did, I have not seen it.

    Not yet, but I think I may have a PSU issue. I have a replacement arriving on Monday.

    No no issues with my power supply. Just return from the Moon.
