    Hi! I'm from the Internet
    If you can put a 7770 or 7850 in a quad system and run 3 wu's and only do gpu wu's it works like a charm. Also you cpu load never goes over 50% which keeps it nice and cool and it will use all the cores. This is the way I did with my 7850 system and the thing runs very cool. Also the system is very usable. You hardly notice and lag from it even with running 3 wu's on the gpu.

    I'm around 1800W with both 4P rigs. Should cost about $180.00 to run both rigs 24/7. Huge difference in price is I have Tallahassee Utilities now(cheaper rates by .02/KW) and they do not penalize and charge a much higherrate for over 1500W/household like FPL did. Plus is I have heat for the winter:rockout:.

    Well, I'm certainly not interested in giving up on CPU crunching. I may move the GTX470s to the i920 rig to that I have a more usable desktop, but I'm certainly going to leave the other four threads crunching regardless. Heat and power usage aren't really a concern for me ATM, and I'd like to support the other projects (and get my badges in them). But I could definitely see running 3 HCC GPU WUs on a HD7770 or HD7850 and then 5 WUs on the CPU as well :toast:
    Here in central NC we pay about 9-10 cents/kWh.

    I guess that isn't too bad then. A third of your previous bill is no laughing matter. Why wasn't TU an option before? And does it ever get cold enough in FL for you to even need heat? :p

    You pay ~4.5 cents/kWH in Canada? :eek:

    Not only do you get wicked cheap electricity, but you can use the computer to heat the house nine months out of the year :eek: :rockout:

    For now though, I'm in a university dorm, and electricity is free :)

    You guys have it too good lol. We get tiered costs here, the first units cost more than the subsequent ones. Makes it quite hard to know how much it's really costing since it seems to change each time. On average.. looking at about 13p (20 cents) per kWh.

    The good ol SB fleet was about 300$ a month. Once this SR-2 is the sole cruncher left.. looking at maybe 100$. Too bad there's a 8% price hike coming, gonna need to limit the hours of use :shadedshu

    That's really quite the improvement in power usage :toast:

    If you need to sell more systems... :rolleyes: :cool:
    Yes, you guys do a great job with green energy. I wish we'd do that--but when there's still a national debate about whether global warming is a conspiracy or not, it seems unlikely :shadedshu

    Canada really would be such a marvelous country to live in for so many reasons :respect:

    Yes Bun-Bun does it - "My one rig has a GTX670 and a Radeon 7850 crunching fine. However in order get get both working with app_info I had to create two instances of boinc. One with ATI app_info and the other with Nvidia app_info. I tried combining them but it wouldn't get any nvidia WU's. Been running two days like this.

    Thank you! :respect:

    In that case, I might just have to put the 3rd slot in the i860 to use :toast:

    Will add that to the OP, had it linked before but had no idea if it worked. Good to know that it does. :rockout:

    Got a new 7770 coming tomorrow. This time it will be in my new work PC (i7-920 to replace my dying e8400 rig) so I can monitor it more closely. I might try a "dual WCG set-up" if the 3 GPU simultaneous run refuses to pick up new WUs. When I get it running one way or the other my 970/680 rig will return to folding. It "only" does 15k PPD :)

    Monday I'm going to start working on my 970 w/ GTX480 crunching multiple WU's. :toast:

    EDIT: KieX I still can't get over your rig doing over 100k PPD.. That's awesome brotha! :toast: How many 7770 do you have on that machine?

    He has three going. Incredible PPD for GPU-only crunching on that :eek:

    Yeah they're great little things, even I'm amazed at the 100K output. Between 33-36K each. Comes at a great time too, since I had to sell off most of my old farm and the 260W it uses is reasonable affordable.

    They can run 4WU but the time penalty meant no improvement over 3WU, not even returned units per day. Just encountered my first "no tasks" but setup a WCG profile as ThE_MaD_ShOt suggested, and seems to have worked.

    Has anyone with Nvidia clients got more than 1 WU running? I'm getting errors with the XS script hack, so thinking of going back to this format for multiple GPU WU's.

    I'm hoping to test on the GTX470 rig later. Depends on how long studying takes. The i7-860 is too unreliable ATM for it to be useful for this, but I should be able to get some good results from this :toast:

    Well, came home from work to 2 rigs sitting idle with no work. It's back to a single instance for me. I should have my Son's spare HD6850 in a week, so i might try it on that card.

    Its's different in Toronto.. we have electricity pricing based on when you're using it (Time of Day)

    Ranges from 6.5 cents / kWh to 11.7 cents..
