The short circuit in the VRMs prevented the machine from even powering up.

Thanks for your answer. I take this problem really serioiusly.
Are there any tests/SW/tools you can recommend that prove that something is wrong with my GPU?

Any 3D intensive application will do the trick : choose the game of your choice or a benchmark like 3DMark or FurMark ...

toTow, as I mentioned in my previous post it is stable in daily life. Benchmarks don't crash my system.
But I lose WUs and you and Bruce argue (probably correctly) that this proves that something wrong with my system.

However, when I return my GPU within warranty period, the manufacturer will decline replacement, when I argue like you.

For that I need proof. Like a diagnostic tool that shows a specific problem with the gpu.

Thanks for your help.

RABishop: I note that you have GTX-1080s and are using the FIRST driver introduced that supports GTX-1080s:

> looked, and my driver for all is the newest I know of or can find, which is the 367.27.

With OpenMM, we've had some issues with this early driver (released 2016.6.13) causing NaNs on GTX-1080s. The latest linux driver is 375.26 (released 2016.12.14): ... 2992/en-us

Any chance you could try this recent driver?

RABiship, I would install Nvidia driver 373.06. As of late, it seems to the best for stability, and generally enables very good performance. I'm using 373.06 with 1080s and a 1070.

I'm having a problem similar to this. I'm trying to get a GTX 1080 FTW card to function in a new configured machine. Project # THIS time is 8207. Work Server #: Collection Server #: I have tried many times uninstalling, reinstalling, purging everything. Every time I try to get the first GPU to run, it tries, then fails, over and over again. I have the newest available NVIDIA Driver installed: 384.69, amd 64.

06:04:20:WARNING:WU01:FS01:FahCore returned: BAD_WORK_UNIT (114 = 0x72)

06:05:54:WARNING:WU02:FS01:FahCore returned: BAD_WORK_UNIT (114 = 0x72)

I am becoming a bit annoyed with this, to say the least.

ClEnqueueReadBuffer (N) errors are being reported by OpenCL. As a general rule, they're closely related to driver errors or resulting from flaky hardware or other instabilities. ( I really don't have a list of the varous values of N to any particular condition. As with all instabilities, you may or may not be able to fix it by simple underclocking or improving the cooling.

-5 is the code for CL_OUT_OF_RESOURCES error, which is logical when it happens while the GPU is reset by the driver, because when it's being reset, there no resources available ...
