Any ideas?

Thank you in advance.

All 3 WU's were failed with the new 6.14 client. The new 6.14 application runs at higher GPU usage. I guess your system can't handle the consequences of this higher GPU utilization. Maybe the power supply, maybe the cooling, maybe both.

It shouldn't be an hardware issue: Corsair 750W CMPSU-750AXEU, CM 690 II LITE, and a Gtx 560 Ti that never surpassed 74°C with GpuGrid (no problem up to more than 85°C with Furmark).

First port of call would be to upgrade to latest driver.

All showa's errors were for standard length KASHIF_HIVPR tasks, and all occurred within 20sec. Now shows does not have any tasks.

2 "Energies have become nan" errors
1 "SWAN: FATAL : swanMemcpyDtoH failed - Assertion failed: 0, file swanlib_nv.c, line 390".

All 3 tasks have been resent to other systems. No errors returned from other systems so far and 1 validated. So I expect the problem is with the system.
I would be inclined to shut down, give the computer (especially GPU) a clean, and increase the fan speeds before trying again.
The latest driver might help too.
I would also suggest you try to manually control what tasks you get (one at a time, and if they fail stop and try the long tasks).

Good luck,

I'm quite sure it's not an hardware issue: my pc crunched 10/15 wus for Milkyway@Home, and I got no errors whatsoever. GPU load up to 97-98%, temperatures up to 78°C.
As soon as I can, I'll install new drivers, and I'll try to crunch other wus for this project.
By the way, what drivers are recommended?

Bye.

That just proves that your card is not totally messed up; GPUGrid tasks are not the same and tax the system in a different way. Also a 10 or 15min MW task is not the same as crunching a 12h task here. The chances of failure over 10min is much less than over 12h. It also suggests that the drivers are not totally messed up, and yet you still have a problem.

Did you try anything I suggested?
Shut down, clean fans, increase fan speeds, use the latest driver (27533).

I'm aware that Milky wu aren't the same of Gpugrid.
As soon as I'm able to perform a system restart, I'll:
- clean the fans
- install Windoze update
- install new drivers for my Nvidia card
not necessarily in this order ;)

Did you overclock the GPU? GPUGRID and overclocking doesn't seem to go well together. Anything over 10% seems to cause my WUs to error out.

No, the gpu is @ default.
Since my post, I haven't been able to crunch for Gpugrid anymore, while I still can for Milkyway.
Don't know what to think.

We are now using a different Windows app (6.15), so you might want try here again.

Don't know why, but I can crunch (at least, so far) for 6.15 version.
