    7750 + Pentium G620. I have a GT520 in the same machine for physx but it doesn't seem to be doing anything.

    A GT520 is slow enough that it won't really do any good. If you want to set up two GPU WUs, it would certainly boost your output considerably :toast:

    I don't know, I'm hitting 65C on a single WU. Case has poor airflow (2x60mm fans as exhaust and a single 80mm at the front.)

    Depending on intake possibillities for air (vents) it may be worthwile to try to put all fans on exhaust.

    I had just recommissioned my folding rig after a month of sitting idle today. Looks like it's jumping ship for now. Is a GTS 250 worth the power used?

    Hi all. Just begin crunching. Previously was doing folding. Is it essentially the same?

    Better do not let a GTS 250 crunch for the WCG, because it crunches as fast as my HD 6670 at best, in despite of its raw power and electricity draw ("crunching" draw is not equal to "peak" draw though, fortunately, in case of WCG). Unless you do not mind a less than ideal power draw/output ratio I recommend to crunch on the CPU only on that system.

    F@H pretty much simulates the "folding" of proteins in human bodies, while number crunching varies more (generally) in terms of what kind of calculations are being made. It can be folding (in case of the "Human Proteome Folding" WCG subproject) but also for example an attempt to predict how certain chemicals respond to each other in certain cercumstances, or predicting future climatic circumstance (climateprediction.net, not part of WCG).

    Should I just leave my Fermis and Kepler folding and crunch CPU only then? I'm all about efficiency.

    Definitely, the ATI/AMD cards are for crunchers what the nVidia cards are for folding.

    Alright, I'll do that. The only compute capable ATI card I have is a dead 4850 and it's at my mother's.

    The 4850 is not considered compatible by the WCG folks, so BOINC would not do anything with it anayway. :)

    With max HCC GPU WUs (I believe about 5 WUs), my 580 can do ~30kPPD @ 875core. Not as great as AMD, but I believe its better than Kepler and it far outpaces what my i7 3770K does running 24/7 on its own @ 4.2ghz (~5kPPD). Even considering that the Fermi card will use more power, it is still a very efficient way to crunch considering the watt:pPD.

    Count me in

    OK so I'll give this a try.

    Is it a 24/7 kind of thing or what?

    I'm totally newb to this...

    My HD 6670 DDR3 does one WU in about 12 minutes (one WU at a time), a GTS 450 does about the same according to Brandonwh64 (so a higher middle class nVidia is doing as well as a lower middle class AMD of ~50 watts peak).

    What are you planning to crunch with? CPU and/or GPU?

    I have an "old" qx9770 running stock and 2 ATI 5850s. If I'm not doing anything important on my PC, I don't mind having the cpu and gfxs working 100%.

    Just need to see how to set it all up. Not even sure 5850s will work...

    HD 5850s will work. You could let those run one GPU WU per GPU (and two normal WUs on the two cores that do not drive the GPUs), or alternatively you could run multiple WUs per GPU (still using 2 cores for the GPUs and 2 for regular WUs and/or other tasks).
    The latter should be giving a higher daily output as well as a better output per watt, but it will probably bring the power draw of the GPUs closer to their peak power draw.
    The firstmentioned option will be using slightly less power and generate less output, but will be easier to setup.

    However, I think that [Ion], Norton, HammerOn or ChickenPatty can give better advice on this.

    Since I weren't in any team, you can count me in too.

    I am crunching on two machines, my main workstation has a Core 2 Duo E8500 and a GeForce GTX 560 Ti (which I will put to work when I am AFK now that I need those 25k points), the second PC is an Athlon XP 2500+.

    Not sure how to go about setting up what cores do what...

    I have the impression my GPUs aren't working (0-25% load on the first 5850 but 0% load on the other 5850).

    My cpu is working nicely though.

    I did try setting some things in my device profile, but maybe I missed something?

    Any help appreciated.

    @Lukfi: In a month, it will be do-able to crunch on the AthlonXP and Core 2 Duo and get 25000 WCG points (which should not be confused with BOINC points). There is no strict need to crunch on the GTX 560 although it is encouraged to do so if you do not mind the additional power draw.
