    :shadedshu I'm all out of ideas with this one. If you login to the WCG site and check the Forums there's a GPU Support section where you could put your query. There are people who may know how to solve that issue there?

    http://www.worldcommunitygrid.org/forums/wcg/listthreads?forum=560

    Yeah.. that could also be a route. Not sure how much patience you have by now seems like these files either work no problem or cause a headache.

    EDIT: GPU would crash after every few completed units (corrupting the two it was working on) so I went back to no info file. Going to try 12.11b4 tomorrow. :banghead:

    I got it working. Seems my 7950 can only run 2 WUs at once with 95-98% usage, and it takes just under 2 minutes for 2 WUs if I am reading it right. I manually added the registry keys and DWORD values but they did nothing when I tried 3 WUs.

    Hi! I'm from the Internet
    Oky I had a problem with my rig with 7850 in it. So I went ahead and blew out my boinc install and redid it. Now I have it set to do 3 wu's at a time. Was taking about 2.2 mins per wu. Now it's 3.2 per wu. And if we figure this the correct way thats averages out to just over 1.6 mins per unit. :toast: Load is 92% temp is 52c fan speed 35%. I will keep an eye on it through out the night and if all goes well I will post my exact procedure. Oh and the app info file seems to not work just right with the newest boinc client from the boinc site. At least for me anyway. I am using the one from WCG site. All is great so far.




    As of 8am all is still good. That rig is up to 32 pages of pendings now. I have a total of 46 between all rigs. Once the pending start evening out it ought to start producing great numbers. :toast:

    That's amazing indeed! Between all of my cards, I'm getting about a WU done every 1.5 minutes...now just to wait until the cache empties out so I can do the tweak :banghead:

    I'm back to 1 WU at a time without the config due to my GPU crashing every few minutes as I edited in my post above. I am going to try the newest AMD drivers, but I think this could be a Win8 issue. Don't know yet, though.

    This is likely the issue with Win8 not be able to run the BOINC manager available on the WCG website.
    As Mad Shot stated the WCG version seems to work OK for the multiple wu's but the BOINC one, that works with Win8, has issues. :shadedshu

    Hi! I'm from the Internet
    And my rig has stopped reporting and getting work. Don't know what the issue is but I am thinking I am going to go back to just the basic install and do 1 unit at a time. There's just to many bugs with this and I can't baby sit the rig to work out all the problems.


    Edit: Working fine again. Don't know what the issue was but that rig does some strange freaky stuff.




    I wrote that wrong. It was doing a wu in 2mins and 20 secs. Now it is taking 3 mins and 20 secs to do each wu running them 3 at a time. And that averages to just about 1 min and 6.5 secs per wu.

    After several hours of reading on others sites today, i'll stay with the basic gpu install
    like ThE_MaD_ShOt says I can't '' baby sit'' my rigs when i'm at work

    For me the best way to have more point is to have more core or gpu
    I'm working on it :toast:

    Hi! I'm from the Internet
    What I did was uninstall boinc/wcg . Then I went in a deleted the folder under program data. Rebooted. Went onto wcg site a made a profile with just hcc and made it default. I set this rig to use that profile on wcg site. Then I installed the client from wcg site. Not the one from Boinc site. rebooted again. Right after you load the project and as quick as you can click no new task. Shut down the client. Add the app_Info file. I used the gpu only file. Then I restarted the client and hit allow new task. All is good. I rebooted again after everything was done just because.


    Now the rig stopped reporting for 4 hrs today but I think it was the rig itself and nothing to do with wcg as it just started back on it's own again.

    And even being down for 4 hrs it has already done 20k in ppd so far with just over 3 hrs to go.

    Well, it's midnight for WCG.. so going to try something new tomorrow:

    4WU per card. Did 3 like a champ.. hoping it can cope with one more. Current estimate is ~2WU per minute or perhaps batches of 12WU every 5min

    EDIT: If anyone was wondering, I'm using these cards, cheapest I could find: http://uk.msi.com/product/vga/R7770-PMD1GD5.html

    Hi! I'm from the Internet
    If they say we are going to have gpu units for the long haul, my butt is going to load up with 7850's. Seven rigs, 2 pci-e slots per rig, 3 wu's per card, hmm 42 wu's every 3 mins. LOL So this also means I have to swap in x6's in all systems and upgrade the whole x2 system.

    Fingers crossed, very uncertain now. Mind you, there is the electricity cost to consider. Too many GPU's can easily run up the bills. I'm content with these since they're cheaper to run than 2 SB's. The worst will be summer though.. bedroom furnace!

    True. Maybe I will just cut my fleet down to 3 rigs.

    I remember my GPU folding days. i was easily using in excess of 2500 watts 24/7. Electric bill was like $600 USD. Not very sustainable...

    Mine is right at $250 right now but I still have the a/c on during the day. We like it cold.

    That's really phenomenal. Yes, GPUs are fast, but 120k PPD (or more) seems all but unbelievable from just two cards. That's a million points a week from one rig....or about eight times what I accomplished with the PentDCs.
    Wow..just beautiful! :respect:
    These HD7770s are pretty much just too good to pass one--does anyone know about the effects of running nV and AMD cards in one rig for WCG?
    Yeah, less power than two of the SB setups, and nearly 10x the output! A hard thing to beat!
    :rolleyes:
    Aren't you approaching 2000w at this point with the two 4P rigs?

    I know you can run the 2 cards in one rig. I'm not sure about how nice it's going to play with wcg though. I do know you won't be able to use the app_info files as they are gpu specific. Unless theres someone out there that knows what it would take to write one that can use 2 different makes of cards.

    Alright. I can always throw a HD7770 or HD7850 in one of my dual-core systems--but I'd be limited to two WUs at a time. Hopefully I'll have my i7-920 back from RMA this week and then can get that system assembled--we'll see I guess :ohwell:
