    Maybe DistrRTgen? It is for searching after weak hashes and pretty useful (yes the "Rainbow Tables" will be publicly available). You do not pay for the power bill IIRC, so it might be worth consideration (others must keep the higher GPU load in mindbecause of the power bills).

    On a sidenote, there is very little lag while I am typing this. In fact, only scrolling does so that is quirte a difference compared to the WCG GPU WUs. (toast)
    I will still run the DistrRTgen WUs only a few hours per night though, because of the power draw.

    i'd be interested in trying that and seeing the difference in power. The HCC gpu WUs haven't been too bad for me power wise, so it hasn't been a real deterrent.

    My HD 6670 is now running its first DistrRTgen unit since about an hour, the remaining time is estimated to be another 2 hours. Lag seems less present, although the GPU load seems higher judging by the temps.
    Do not forget to disable CPU WUs for the project if you want to reserve the CPU cores for WCG; and the team to join is the one founded by Mathew-3770K, i.e. the unofficial "TechPowerUp!" team. The link to the project is in my signature.

    Edit: According to Afterburner, the GPU load has dropped significantly now (for a while at least it, can be as high as 98% but as low as 5%), as well as the temperatures. So overall the power draw might be similar to the HCC WUs (assuming one WU at a time).

    I see I got 26K today and I still have 50+ pages of pendings but I guess I'll run out by Wednesday. Luckily I'll be back on Thursday to crunch more. :peace:

    OMG look at the credits I get for 1 GPU WU for DistrRTgen! Those with 87 cobblestones are regular CPU WUs (which I have disabled now for that particular project).

    Hi! I'm from the Internet
    I agree with you. I just bought another 7850 but I am also going to use it in crossfire with the one I have for gaming. If it wasn't for that I would have used the money elsewhere. :toast:






    I have decided to go ahead and pull this from being for sale. When the gpu unit's run out I want to have some fire power in the way of cpu cores to put into action.

    Just a heads up for anyone looking to pick up another GCN GPU, Tom's Hardware and Newegg have a special going for Power Color's 7870XT. It's $208.79 with free shipping after the promo code.

    Link

    The 7870XT (or 7930 to lessen confusion) offers a seriously solid price/performance ratio. Linearly taking the clock speed multiplied by stream processors all over price gives this card the best # of Ghz Stream Processors/Dollar ratio of any card in the HD 7000 lineup at the moment.
    Example:
    HD 7770
    640 SP x 1.0 Ghz / $110 = 5.818 GHzSP/Dollar

    HD 7870XT
    1536 x .975 Ghz (Boost) / $210 = 7.131 GhzSP/Dollar

    Obviously, performance isn't that simple, especially in games. From what I understand, though, HCC-GPU WU's scale fairly linearly with an increase in SP's on GCN.

    I'm considering picking up one or two myself. My only concern would be the longterm limitation of 2GB of VRAM, and perhaps the cooler isn't the most robust I've ever seen. My grandpa passed away two weeks ago after a lengthy bought with Lung Cancer, and seeing as I'll be getting some inheritance in the not too distant future, I'd like to get a new rig up and crunching in his memory. Hopefully the promo code/stock holds out for a bit, but if it doesn't, I'm sure another deal will come along. 7950's have been plummeting.

    +1 sorry to hear about your grandfather Xenturion- I lost both of mine a bunch of years ago :(

    As far as gpu purchases... that'a a good price on the 7870XT (or 7890/7930 whatever :rolleyes:). I'm going to wait a bit to see what the 7790 does to all of the pricing on the other cards before deciding if I'm going to pick up another gpu.

    Okay, a few WUs later I can say that the GPU load usually is around 80%, that is lower than the HCC WUs, by my knowledge. That first DistrRTgen GPU WU simply had some high peaks in it, as it seems.

    Whats the interest in distrrgen? Is it just because it does not lag? I know milkyway@home also does amd gpu work.

    Anyone know anything about how the 7790 does?

    grabbing a Tt TR2 500w and a Hyper 212 EVO on thursday :D after that its just the CPU and Win 7, i'll grab a SSD in May. I should have this rig ready to go by April 20th :p

    Myself, [Ion] and manofthem were discussing candidate projects for our GPUs to switch to after the WCG GPU WUs have dried up.

    I was checking out whether it could work well enough with my HD 6670 (after all it is not an über-powerful card), and generating Rainbow Tables in order to discover weak hashes (encryption related) seems useful to me.
    There is some lag with my card (less than with WCG), but that may be not the case with more powerful GPUs. In addition, both CPU cores are kept available for CPU crunching which is not the case with the WCG GPU WUs.

    I might check out Milkyway@home as well.

    I've decided that I might as well OC the 3930k a bit more now that it's running under better cooling--at 4.17GHz it was in the low-50s with peaks in the upper 50s. Now I'm running it at 4.48GHz and IBT load temps are in the low-to-mid 50s with peaks between 56 and 60C. It's going to run a stress test for at least a bit longer, but then it's back to WCG. Provided that all is well over the net few days, and time permitting, I may have to push it higher this weekend.

    I'm beyond impressed with this WC setup :D

    I certainly appreciate your endeavors in the GPU field. :respect: I don't have the time really to figure it all out, so it'll be nice to know what options are open after the HCC gpu WUs are done.

    you would think that the other projects through BIONC/WCG would take heed of open CL and make more GPU wu's available over more projects.

    Even if it is not as fast as a normal HD 7750, it still is an awesome deal (it is slightly less than what I paid for my HD 6670 DDR3).

    others have said that for WCG it should have any performance penalty.

    Really? Those are like 100 euro (~120USD) here.

    In other news, I attached my PC to POEM@home (set on GPU work only). Within a few days, I should have aquired some WUs so that I can say how well that project runs for me (it is protein related research).
