The GPU task does not seem to run well and stopped with state: "Waiting for memory".
Also it seems the GPU is crashing somehow as seen in the below nvidia-smi output:

GPU 00000000:02:00.0: Detected Critical Xid Error


The CPU work units seem to be running normally, but GPU work load is not passing.
System info:

I think the GPU is possibly overheating and kicked out form the bus, but not sure why this happens.

The GPU tasks are aborting like this...

It looks like this is caused by low memory that I should increase the
Options->Memory to 90% (from earlier 50%).

Then it worked for about 3-5 minutes until the GPU overheated and system was forced to shutdown.

So it looks not possible to get the GPU tasks working in this machine.

Jari? Mine says all the time (well ok, not "all" the time, but "a lot") 'waiting for memory', and then you just go do something else, and it starts to work again. I would not worry about it, if I were you (just suppose that was a bad thing... then how com I 'discovered' already 6 amicable pairs?)

Jari... I find that there are always two or three different Amicable Numbers-projects going on in my Boinc manager, what helps me, and maybe you too, is to check up on their progress every so often, and sometimes switch to a project that 'moves forward' instead of 'sticking with the project' that you were busy with but "got stuck" cuz it 'waits for memory' or 'the CPU is busy' or whatever it says
