Have been unable to run GPUGRID consistently. I used to run it for a fair amount of time but then my system suddenly began to have power off events. I run a number of other GPU intensive projects without issue but can't seem to run GPUGRID. I have the following applications settings:

ACEMD short runs (2-3 hours on fastest card): yes
ACEMD long runs (8-12 hours on fastest GPU): yes
ACEMD Beta: no
Python Runtime: yes

Any advice on getting to the bottom of this would be appreciated.

Windows 10 Pro 64Bit
[2] Intel(R) Xeon(R) CPU X5690 @ 3.47GHz
[2] NVIDIA GeForce GTX TITAN Black, Driver: 381.65 OpenCL: 1.2

I would detach from GPUGrid and then re-attach. There might be something corrupted in BOINC due to the power outages.

Sounds like a power supply issue.

You might try stress-testing your system, using tools like:

[for CPU]:
- Prime95
- Intel LINPACK dlls put into LinX

[for GPU]:
- Heaven
- Valley
- PrimeGrid

Might need to test CPU stress alongside GPU stress, ie: run multiple programs at once.

I would like to add furmark for GPU testing.
Before you do any stress test: power off your PC, unplug the power cord, then disconnect all power connectors inside your PC (especially the CPU, 24-pin MB, PCI-e GPU connectors) and check for any burn or melting marks (especially on the 12V (yellow cable) pins of the 24-pin MB connector). If there's none, reconnect them and the power cord, and then do the stress test.

Checked every cable and connection. Suspected PSU even though the 1100 watt system ran Furmark without issue. Added supplementary PSU, no joy. Finally picked up a used Supermicro box w/1280 watt PSU, moved my major components over and problem solved. New problem after, major increase in electricity but happily crunching away. Thanks for the advice.
