I am doing 4 per card and it worked fine until I updated the client
Ok. I guess it is a matter of defaulting to one WU per card to see whether the probblem persists.
you can't revert?
I got my rig back up and running. Now cooled with water. Now running 4.5ghz on 2500k at 50c instead of 65c, and 7970 running 1150mhz at 35c. Cpu temps are a bit higher than I expected but it is only an DD mc-tdx. Just starting to overclock my gpu higher, my aim is 1300mhz.
I wonder how high my ppd will be when all is said and done.
You should easily go over 100k ppd and possibly 150k but watch your results.... sometimes you can end up with a bunch of errors or invalid results if you push too hard
I will look for erros. Before I was getting 136000
GTX280 is a dud. no gpu WU for me XD
My gtx280 is doing fine right now with the wu's. Just takes about 10 to 12 mins per unit which isn't to bad.
Also brandon have you tried going back to the older client? I am still using the one fro m Wcg site on all my rigs without issue. Hell even the rig I put together this past weekend got it and it's version 6 something. Also I am still running the app_info file with it and doing great.
Is that with multiple WUs? I get that with my 6670 when doing one WU at a time on the card.
nV cards are just awful for this. My GTS450 took close to 20 minutes/WU. Even the GTX460s take ten.
I would not say "awful". My GTX570 is running 4 wu's and averaging 12 mins each. On the other hand the GTX560Ti448 is running 4 wu's @ 17-18 mins each. Every bit of hardware for "the cause"!
I guess it's relative
I'm just spoiled by the HD7930, which does 8 WUs at once in about 9 minutes each. Or the HD7950 (which I strongly suspect is CPU limited) that does 10 WUs at once in about 11 minutes each.
And even the GTS450 still beats the pants off of my Atom or Core 2 Duos
I think you're CPU limited there Ion. My 7950 @ 1175/1500 starts off at 8:30-9:30 and once the WUs stagger I've seen completion times as low as 6:30-7:30. 10 WUs with 0.8 4.3GHz cores each.
I threw up 2 939 combos on my FS thread but I'm doubtful anyone is going to be interested. Probably going to get raped over shipping charges anyway. :shadedshu
How do you all guys set the amount of WU's that can be processed by the GPU, in the config? It's up to the card specs/BOINC capable work?
I assume I am...it's just running on an i3. When I get my Xeon DP setup (either Thursday or Sunday, most likely) then I'll move the HD7950 to it and put the GTX460 back in the i3. I figure that way I can run 10 WUs on the HD7950 at .7 CPU cores each and then have 1 WU running on the CPU (currently doing 8x.667 on the HD7930 and i7-860).
I'd be interested in the S939s if I didn't have such easy access to C2Ds---when I can get nearly a complete 2.4GHz C2D system for $20, it's hard to justify buying similar stuff.
@SirKeldon: Instructions here: www.techpowerup.com/forums/showthread.php?t=174138
Basically, you create a file called app_config.xml that tells BOINC that the HCC GPU app really only needs a fraction of a GPU to run on. For powerful cards, it boosts the output significantly. The ideal number of WUs/GPU is experimentally determined.
Thanks [Ion], crunching again with CPU+GPU for 4 WU at the same time
Awesome, I'm glad to hear that you have things crunching!
Yes, on Windows though ... tomorrow i will install the MCW82 for the 6850, let's see how it goes
It has been running for a several hours now. If I had an error would it be in the notices? Where would it show that? I don't think I have had any. Runs really stable in games and all that.
You can check your WCG Result Status page : www.worldcommunitygrid.org/ms/viewBoincResults.do
Or just click "Projects" tab from BOINC manager, highlight World Community Grid project and click "Result Status" button on the left panel.
Change the Result Status filter to Error (or sometimes Invalid) and hit Filter button.
Anyone else getting the "No tasks are available for Help Conquer Cancer message"? So far, it's already crippled my HD7950
Keep an eye on your rigs- according to this WCG Forum post we should see work flowing again shortly
Just one. System is so crippled with just the one I would hate to try more on it. That and the psu get uiet warm also. I have another psu on the way for it. May try more wu's once i install it. Last thing I want to do is have that rig burn out another psu right now. That damn card pulls some amps when under load.
Need major fracking help! got the HD5450 crunching, got ALL computational error, they are failing within 1-2seconds one after another. what's wrong, i haven't configured anything, it's attempting 1CPU+1ATI GPU
Using 12.11 drivers and latest AMD stream SDK
Does a monitor need to be plugged in or something?
