In the last 6 days I had two work units crashing after 50.000 and 73.000 seconds, respectively.

http://www.gpugrid.net/workunit.php?wuid=869267

Both were running on my NVIDIA GeForce 9800 GT (1024MB) driver: 19062 using Boinc 6.6.36

Apperently I wasn't the first with these units crashing (also on GT/GTX 9800 and Boinc version 6.6.36), however, I was the last since both units went fine on a GTX 260 afterwards.

The error message in all cases was Cuda error: Kernel [pme_fill_charges_accumulate] failed in file 'fillcharges.cu' in line 73 : unknown error.

Any suggestions what to do? Despite these two work units, all other units didn't have any problems. It just would be nice to avoid loosing more than 100k seconds of GPU time within one week...Thanks.

And just another one bit the dust......that makes it 3 fails out of the last 13.

Any comment on this issue or should I look for another CUDA project??

their will be some bad apples every once in awhile unless someone really screws up the compiler. just the other day, i had my first wu error for the first time since july........ 4 months without a single error is lucky....

Sure errors may occur once in a while, but this may seem to be a systematic one, since 9800GT likes to crash while GTX260 has no problem with the same WU. Apart from wasting lots of GPU hours I would really like to help and report things like these, but for sure it would be nice also to get some feedback.

This is also the first time since July that I run into errors, but 3 from 13 are quite a lot bad apples at a time.....

Seem all of sudden the G92 and below based cards are computing bullshit.

I can report a similar problem here, my GT200b machine does the job just fine, but my G92 based machine is calculating producing recently a 100% error rate.

i think of switching that one to another project, but i have no idea wich one yet.
Collatz is most of the time out of order, milkyway does not support my G92, for Seti is no Linux Cuda Client avaiable, Aqua stept back from GPU processing at all. Seem i am stuck on this project.

Does anyone know a alternative project where we could join instead of getting crazy trying figure whats the matter here (once again) ?

To be honest i am really getting sick of that crap every now and then.

I was having lots of problems with my 9800GTX, and a while back had to stop GPUGrid WUs as they were crashing too often. It had crunched very well in the past, and certainly others had 9800GTXs running with no issues, so it was all a little strange, but I couldnt take the blue screens anymore. I suspected the driver but could not say definitively. I am paranoid about cleaning old driver bits out, so it was not that.

I keep track with new drivers as they came out with little change to me so far. I changed to 195.62. It was a whole new world ..... blue screens disappeared, reliability returned, along with my sanity ....

Run it for a couple of weeks now and no changes, rock solid, one blue screen and that was my fault. Probably will get back to crunching here again as I miss doing these WUs for many reasons.

Worth a shot at the new drivers, worked for me so far, yet to do the acid test with a GPUGrid WU, but looking good so far.
