Rig 1: Win7_64 with GTX670 and GTX660Ti - Pass

Rig 2: Win7_64 with GTX480 - Fail (too many exists)

Rig 2: Win7_64 with GTX295 - Fail (too many exists) Yes, I still have one of the old versions that were 2 full cards and not just 2 GPUs on 1 card.

Beta app 8.15(cuda55) passed on all so I'm assuming (ha!) that it is cuda6.0 that's the issue. I'll downgrade the driver on Rig 2 to see if I can get back to work.

Installed 331.82 and requested work ... got this message in the event log:

3/19/2014 6:16:23 PM | GPUGRID | NVIDIA GPU: Upgrade to the latest driver to use all of this project's GPU applications

I don't think that's really what I want to do right now :-)
I did get a NOELIA long 8.15(cuda55) - and it is processing fine!

I've also been suffering a lot of failures with app v8.15

Your errors are being caused by your GPU getting too hot, turn the fans up to keep them cooler and you should be OK.

Apart from 1 failure it's not the GPU's getting too hot.... They are in well ventilated cases. The one that came up with high temps was after a reboot when I failed to apply the fan speed after a reboot.

App8.15(CUDA60) units have all been failing on both my systems

Same here. I have three GTX 660s and one GTX 650 Ti, all below 70 C, stable and with no recent failures on CUDA 5.5 work. They have been failing all CUDA 6.0 work units; about 10 thus far. They are all on WinXP with the latest (335.23) drivers.

It looks like some GPU chips are more susceptible than others (both the GTX 660 and 650 Ti use the GK106). The good news is that they fail rapidly (0 seconds). I will try severely under-clocking some more; they have all been over-volted, under-clocked, etc. to be stable thus far, but you never know what new work will bring.

My 780Ti finished one successfully and another one is 50% complete. No errors yet. These WUs run hot.

I just clocked my GPU back to reduce the heat (906 MHz, 77C w/ 70% fan speed. CPU usage is minimal (~2%). GPU load is 82% and power usage is ~85% TDP.

Windows 8.1 with Driver version 335.23

I will try severely under-clocking some more; they have all been over-volted, under-clocked, etc. to be stable thus far, but you never know what new work will bring.

No luck. I went down to 800 MHz on the GPU core (from 993 MHz on one card and 967 MHz on the other), and also reduced the memory clock 200 MHz, but they still crash right away. I think the only hope for these cards is to go back to an earlier driver that does not support CUDA 6.0.

It's my Windows XP machine that seems to be suffering from the CUDA60 failures...

Interesting. I could do Linux, or move them back to a Win7 64-bit machine from whence they came. It might depend on whether there is any performance gain from CUDA 6.0 on these cards, or maybe that is just for the Maxwell cards.

I have two WinXP-32 Pro machines which each have a GTX680 and a GTX460 both of them. They were on the 334.89 driver and were receiving Cuda60 tasks and erroring out within 1-2 seconds. I updated them to 335.23 and they are still erroring out on EVERY Cuda60 task. The Cuda55 and Cuda42 tasks are not a problem. Here is the error message on both machines for each task.

The Win7-64 Pro machine has a pair of GTX780Ti. This machine was not receiving any Cuda60 units with the 331.82 driver. I updated to the 335.23 driver and it is now receiving Cuda60 tasks, and they are completing (3 completed, 2 in progress, 0 errors).

Jim - the error suggests that not all the application files have downloaded. Could you try a project reset/reattach and force the client to d/l all the files again.

OK, I did that on both machines, and each CUDA 6.0 work unit again errored out immediately. Here is a sample:

GPUGRID 8.15 Short runs (2-3 hours on fastest card) (cuda60) 274x-SANTI_MAR423cap310-32-84-RND3062_0 00:00:01 (00:00:00) 3/21/2014 10:57:32 PM 0.729C + 1NV 0.00 Computation error (313,)

Would you like a screen shot of the BOINC folder to look at the files (or of a sub-folder)? I have no anti-virus on either machine, and have disabled the Windows firewall, since the are dedicated machines behind a router with only BOINC running on them.

CUDA60 tasks still erroring out after after project reset on my XP system. Haven't tried detaching and reattaching yet.

Going by the error reported in another thread, this looks like the app is calling a dll file that is for x64 systems.

Is this XP problem limited to x86 (32bit) versions?
Is XP x64 ok with CUDA6?

What about Vista/W7/W8 x86 (32bit) versions?

815 CUDA6 failed on my XP x64 5 out of 5 times, including after project reset. Always crashes after about 235 seconds.

MJH mentioned an 820 app in the other thread - haven't seen one, yet.

Got one running now on my GTX 750Ti. No problems so far in the first 15%...

Apparently the 820 app is only available for short run WUs.
The short run seems to be running fine though.

No luck here - 8.20 CUDA6 Short run failed on XP pro x64 and GTX Titan. Crashed at the same spot as the 8.15 does - 235 seconds in.
