I am getting about a 10% invalid rate on one of my HD 4850s, but cannot figure out why. The stderror_out text looks exactly the same as for a valid WU. Here is what it looks like:

Does anyone out there see anything I am missing? I can see no reason for it to be invalid.

Going through your results it looks like the ones that have an error are returning NaN or some very weird result (as in an impossible result). There might be some kind of hardware issue.

Is your GPU overclocked?

Yes Travis. They were both mildly overclocked. I have set them both back to factory default. Let's see what happens now. Thanks.

Well that fixed it I think. No invalids for over 2 hours now. Strange that they were both overclocked equally but only one was having the problem. Oh well, full steam ahead again.

OK, Cuda working fine, but ATI showing Computation error for all.

I click on the close program button then it moves to the next one and errors that as well. as below

It was running Collatz while the project was down, and still is without problems.

I will try installing 6.10.18 and see if that makes a difference.

Well processor manufacturing isn't an exact science, so some processors overclock better than others :)

Not sure, but it looks like you have the incorrect MilkyWay application version variant installed. I think you require the 64-bit one for Catalyst drivers 9.2 and above. This application variant contains "astronomy_0.20b_ATI_x64_ati.exe". You will need to change all 3 files to the correct version, not just the application itself.

Details and explanations on which application variant is the correct one for your operating system and Catalyst driver version are contained in the readme file included with the download.

If you are swapping graphics cards between different computers with different Windows operating systems (32-bit and 64-bit) and different Catalyst driver versions installed you have to ensure that you are using the correct MilkyWay application variant to match the operating system and Catalyst driver version that is installed on that box.

Thanks.

All running again, seems that when I changed Cal versions it took out the AMD*.dll files as well.

FYI: the 5970 is showing a 25% speed improvement over the 4850. Not really good value, still we need to try.

Cheers.

Don't tell me that I have two in the post.

In fact that has prompted me to go write down the questions about what would be the best 5970 app_info setup in the Optimized App thread. I was wondering what coproc value I need to utilize all those shaders. i.e. if it's 25% speed increase per unit and I can run double the units concurrently then thats aloooot more than 25% performance boost. Heres hoping :) Otherwise I will sell the 5970's and keep the 4850x2's running if 0.5 is still the best answer :)

New WU, in size about 4x what they were before.

5 WU executed and all "Completed, marked as invalid".

System: WinXP, GTX285, driver 190.62, Boinc 6.6.36, app version 0.21 (cuda23)

No problem until these new WU's.

Not sure what my actual error rate is, but, I have over 100 on my system with GTX 295 cards ... there are almost as many that have validated. I know it is possible it is my hardware, though I rate that low for the simple reason that Collatz and GPU Grid also run on these cards and I don't see this kind of error rate. I also did not see this kind of error rate prior to the extension of run times.

I think you should check some of these that are coming back as invalid to see if there might be an application / validator issue ...

My GTX 295's and GTX 260's are all ok with the new WU's, as is the 4850 and the 5970's. One happy cruncher here.
Oh yeah, stats. BOINC 6.10.18, App 20b, cuda 190.62, all on Vista.

Well, my ATI cards have no problems with the tasks it seems. So the question is why do many if not most of them fail on CUDA cards? I have a hard time believing that 4 cards suddenly went bad...
