I am only getting these WUs now - looks like 660 and 750ti are no longer deemed suitable for GPUGRID. Pity.

Just got aanother Noelia (9-NOELIA_005p_express-2-3-RND7707) which crashed after about 3000 seconds.

Should I feel satisfaction that none of the previous 8 failures on this WU (including a Quadro) lasted more than 23 seconds?

When I checked this morning, out of 3 WUs one had completed (santi), one had failed (Noelia - ("ACEMD terminated abnormally" dialog displayed) while a third had managed 5% progress in nearly three hours (also Noelia). This was one with very low memory controller use - it also crashed as soon as I tried to suspend and resume it.

Looking at the several failures I have had in the previous 3 days, most if not all of them have had one or more failures prior to mine. Of the 3 WUs I am currently processing, two are resends after a previous failure (one Noelia and one Santi). The Noelia is one of the slow 290px. It has previously crashed after 16 hours processing on a 660ti. It is now 9% complete after nearly 4 hours.

So the failure rate on current WUs for me is more than 50%. It is happening on all of my cards (2 660 and 1 660ti - I've already moved the 560ti to Folding because of the performance impact running some Noelia WUs on 1GB cards).

Of the WUs I have been able to complete successfully in the last 3 days only one has been a Noelia, and on that one there had been two previous failures on the WU. This is not an acceptable failure rate as far as I am concerned.

Previous Noelia KLEBEs have been ok - just this batch starting with 290px. Anyway the one on the 560ti just crsashed after 20 hours after I had to reboot the PC so I'll give it a rest from long WUs for the moment and see if it handles the new Folding WUs any better.

I have received a bunch of 290xp...Noelia_KLEBEs. They will be lucky to finish within 24 hours (660 and 660ti) or 2 days (560ti with the additional penalty for only 1GB memory). Are these cards now too slow to process long WUs, or is there a problem with them that they run so much longer than earlier WUS?

Thanks!

Ran some memory tests (memtestcl and memtestG80) with no errors (but probably need to run for a day or two to do a thorough check). Then set the card to reference GPU core clock (980/1045), and memory underclocked from 6008 to 5494. It has processed a NOELIA klebe successfully, and is now nearly 2 hours into a NOELIA 7MG (that is working properly with 38% memory controller load).

I also installed the 320.49 driver but this doesn't appear to have made any difference one way or the other (WUs were still crashing before I underclocked the memory).

I'm trying another tack here - wonder if there is some bad memory on the card? After the short WU failed, I underclocked the memory a bit. The next short WU worked OK! OK there were a couple after that did not, but they have failed on other machines also. I've lowered the memory clock a bit more and will see how it goes. I've found a few memory testing tools which I will try also - if there's a memory problem, hopefully I can find a way to reliably show it that will allow the seller to verify the problem.

I notice that there are two BIOS versions for this card - one for cards with Hynix memory, the other for cards with Samsung memory. My card appears to be Samsung.

Just read the thread "Current Noelia WUs" and that explains some of what I am seeing (log-running Noelia_MGs) but of course my 660s are 2GB. Does explain the fact that the Noelia_MGs took twice as ling to complete on my (1 GB) 560 ti.

I tried uninstalling the drivers (again) and reinstalled (310.90). Fetched another WU - got a Noelia_klebe. It actually ran for 15 minutes before crashing (maybe a bit of FurMark helped burn it in :-) ). Environmentals looked OK (certainly much less that FurMark) - GPU 93%, TDP 90%, Mem Controller 34%, Temp 65 degrees.

Then I turned off long tasks and got a short WU. It also crashed, just shy of 10 minutes 145220

I'm just about out of ideas here..

Hi MrS,
I ran the test from the free version of 3DMark 11. It ran fine with results in the midrange of those with same processor and graphics card. Also ran FurMark. It also seemed to run fine. It actually ran with TDP approaching 110%, and you could see that the card had reduced both core clock and voltage. Temps stabilised at 68 degrees with factory fan settings. From memory this would appear to be stressing the card more that GPUGrid was doing when the WUs failed.

Whoops my mistake - should have been 100,000 secs. Sorry..
