    Some good news from me--I tentatively have a buyer for a Dell E4300 I have--if that goes through (tomorrow) then I'll be buying a solid WC setup for the 3930k and hopefully putting an end to the thermal throttling :toast:

    ^^ Have fun with the chip. I had it on a h100 so good water will be treat.:pimp:

    It's running on a Xigmatek Gaia right now which does poorly at best (80C)--but I have ~1500w getting dumped into a small room, so I'd imagine the ambients are wicked high ATM. I think I'll get either a H2O-920 or a 240mm custom kit. Decisions, decisions :)

    You mean the 30 day activation window? You could rearm every 30 days to keep it going to about 4 months.

    I'm going to run them on Ubuntu with remote access from Windows to keep an eye on stuck WUs.

    While new to your forum, I've lurked for a while and appreciate the wealth of information you have shared on GPU processing, which has helped renew my interest in grid computing.

    I was spec'ing a dedicated 'cruncher' with 3x7770's in a HAF-XB when I saw a post that WCG expects the GPU tasks to run out in the June time-frame. While I would not mind switching to other GPU related tasks/projects, I read other posts that seemed to indicate the 7770s may not be as well suited to folding and other projects as they are with WCG's current HCC wu's.

    Could someone with experience with 7770s comment on what other tasks/projects they may be well suited? I have ample CPU crunchers, so if there isn't anything currently well suited for this config, I will likely postpone this until something else comes up.

    Ok guys, At a time in my life I feel needs to be explained. I may possibly start to slow down soon on crunching and this is all due to the fact that my job is being eliminated by the end of the month. This will drop around 1200$ a month for my family income. I will not sell what I have cause I know if I do I will probably not be able to get it back anytime soon. All preparations for money savings have gone into effect which include all work being stopped on my 1965 Ford F100. Shit happens I know and I have put out like 10 applications since hearing of my situation. I still want to remain apart of this community if that means getting point in here and there or setup some kinda of energy saving settings on the 5770 but I will try to trinkle in the points.

    Sorry to hear that Brandon. Hopefully you find work somewhere else soon. Let m,e know if there's anything I can do to help.

    A pair of 7850's or 7870's may be the better option (2x7850's= 3x7770's on performance and cost atm). I saw some info that F@H may be giving better support to Radeon cards... which I am also looking into ;) so you have may have the option to use the cards for F@H if or when GPU crunching has finished.

    @Brandon- that really sucks man... However, it is not BS to say that when one door closes, another opens. Do your best to care of family and keep your mind, ears, and eyes open for that next opportunity ;)

    I appreciate everyone's concern, at this point its all about money saving on the homefront so things have started to cut back like cell phone bill and such. I will try to leave my desktop running at work until the big day comes I must leave (maybe 2 weeks or earlier) but once it is down it could be down for a while.

    Just do what you have to do. In all reality DC is not priority. We all have our moments man. Right now you have more important things to think about.

    Thanks for the input - I'm still evaluating potential GPU's. While price/performance is 'a' factor, it's not the primary driver as I appreciate the constant fluidity of the GPU market. Obviously, just a hobby, but would prefer not to drop 1k+ on a system that is dedicated to GPU crunching only to find limited purpose for it in 3 odd months.

    If WCG doesn't continue GPU work there are other BOINC projects that do.

    The Radeon 7xxx cards should be ideal for any project that has OpenCL support. I believe that it is the GCN architecture on the cards that really makes them stand out.

    The other consideration is double precision (DP) compute performance.... 7750/7770's don't do DP AFAIK, 7850/7870's do, and 7950/7970's do very much. If you want to maximize your chances of having work to do on a GPU then the 7950/7970 cards may be the best bet even if though they are the most expensive.

    I'll likely stay in the middle of the road with 78xx cards and take my chances since I've already invested in them. ;)

    Does your GPU only do WU, or you play a bit games? has if no gaming, thoses HD7850 still cost not too much for good performance.

    So I guess this is the right choice like you said.

    Another excellent point - assuming you are correct that the 7770 cannot do DP, then I would not want those. Thanks for bringing that up.

    My ATI cards used to do awesome in whata it called, Milky Way @home projects?

    Even if they can, the DP output would be lousy compared to a 7970. WCG GPU crunching can scale with # of stream processors- this is not the case with DP performance. iirc a 7970 can do over 1Tflop in DP

    Not sure how well they do now.... seems like performance changes (sometimes better/sometimes worse) with each architecture change :ohwell:

    I used my 6xxx series and it did pretty good.

    My 6950 did awesome in milky way. I have well over a million credits from it.

    First of all, good luck to you and your relatives. Secondly, I recommend highly to setup your WCG profile to allow power management to take effect, only crunching on computers your family uses anyway. Maybe going from CFX to single-card might help to save power also, but with the decreasing idle draw of gfx cards with each new gen I doubt it would make much difference. Stopping to crunch on GPUs (or underclocking them) should help you save power too.

    Before you underclock, try seeing how low you can go with voltage while having stock clocks. That is how people get the most work/watts when mining bitcoins. Do the same with your cpu if you want to bring its power down also.

    damn it bro, I am very sorry to hear this turn of events or luck for sure!!

    I am pretty much in the same boat at the moment. With the PRP that I have I couldn't perform my daily duties at work and got laid off. I am however able to draw unemployment but that is about 2/3rds the income I was used to. Needless to say, like you, I had to cut back on a lot of spending. :banghead:

    Keep us informed on this development brother! :respect:
