    Consistency is key my friend, I think you know that. :)

    That I do. Hence why I'd rather have a stable ~24k PPD than an erratic 31k :toast:

    Maybe I'll pick up another GPU later this week--we'll have to see :toast:

    Bro, this stuffs like crack man :roll:

    Just wish I was in a situation like I was back in the days where I blew all my money on hardware. :( Especially now that everyone is kicking ass, makes me want to add to the team, but really can't. :(

    Anyhow, speaking of consistency, working my way up to 5 million day by day. :)

    Congrats, 5 mill is an awesome stone indeed! :toast:
    You'll make it sooner or later :)

    I totally understand about the HW. I'm probably going overboard--but so be it, I made a great profit this summer and I'm doing something good with it :toast:

    Mine started out higher and settled in about a minute faster. You might just let it settle a little. I think it would be great if there was a way to stagger them a little more. Even with 12 running, the all seem to go at once, report at once, upload at once...

    Well, I've now fully switched back to 1 GPU WU and 7 CPU WUs on the i7-920/HD7770. It'll stay like this for now--perhaps I'll try changing it again tomorrow. Only lost a few hours...

    Yeah I'm hoping so too. You guys have sorta been through it with me so you know what's going on.

    Can't wait for better, hardware filled days. :p

    i got a few 5870's multi wu'ing now, they work FAARR better than my 680's.

    I used the straight info file for gpu's only. Havent tried mixing it with cpu wu's thou.

    Well, I'm going to try multiple WUs again this weekend. I think part of the reason I wasn't getting new WUs is that WCG was trying to send me GFAM WUs from the last installation, and it didn't know what to do with them. I'll try emptying out the buffer and then doing the multi-WU tweak to see what I can get.

    I hope it works for you and you receive enough work to stress that 7770! It's going to add some nice points to this week of the competition :) :)

    Just switched my rig from GPU only to GPU+CPU HCC. Had a similar problem with not receiving WU. Had to basically remove the WCG account from BOINC, re-attach to project, then select no tasks before downloading any. Close down BOINC, put file and then restart with no problems.

    Long story short, BOINC needs to download all the project files before you can use app_info without problem. And any major change to app_info file, requires to re-download again from scratch by removing project from BOINC.

    Indeed. And now that we have you and t_ski going full bore, we'll be unstoppable! :rockout:
    Thanks for letting me know! :toast:
    Particularly if I end up with a second GPU, the extra PPD really does add up :toast:

    What's the app_info file that you used?

    Created one using the code from two others. Set for 3 WU per GPU using a full core each, and then the rest with CPU WU:

    Awesome. Thanks for that! I'll start clearing out my buffer--I should have time tomorrow afternoon to play with it :)

    Major change, yes. However, I was able to edit the GPU count number without trouble.

    It's only running one GPU work unit at a time. I tried setting it up for two...

    Can you run an update on BOINC and copy the messages from the Event Log (Ctrl+shift+e)?

    ***
    UPDATE on app_info:

    There seems to be BETA WU out for testing multiple images per WU. For now it seems that this may cause people with app_info files to run dry.:ohwell:

    On the plus side, if this test works well.. the newer WU will be rolled out possibly from next week.

    It behaved normally, like the app_info file wasn't there. Oh well, if there's going to be an update that does this without finicky tweaking then I'll just wait for that.
