Hi everyone!

Yesterday I started receiving lots of computation errors on GPU tasks. Yet few tasks were successful. My computer often reboots or driver crashes. I have installed the latest NVidia driver yet situation stays the same. Stressing GPU, CPU and memory shows no problems. All Seti@Home GPU tasks are successful.

Here's link to my error tasks: https://einsteinathome.org/host/12298595/tasks/error

All errors are related to error during CUDA device->host HS data transfer. I have PCI-E 2.0 8x card installed to PCI-E 1.1 16x slot so the bandwidth is halved - can this be the reason for errors? Why these errors started to appear so suddenly yet few days ago everything was perfect?

Can anyone point me the direction on how can I resolve this problems? Should I change motherboard and/or CPU, or should I change graphics card? Maybe my GPU does not receive enough power and I should change PSU?

Have you checked the temps

Have you checked the temps for both the CPU and GPU?
When was the last time you cleaned the heat sinks/fans?

Try downgrading the GPU driver to one the was working before, the latest isn't always the greatest.

The temps are OK - CPU 51

The temps are OK - CPU 51 max, GPU 53 max. Heatsinks/fans are cleaned monthly.

No GPU driver was working fine. Tried to upgrade and downgrade - all the same.

CPU and GPU not overclocked.

Reduced CPU usage to 1 core (I used 2 cores before) - the system became more stable.
