It appears that this may have been due to a physical misconfiguration. When I installed the second card, the system had two PCI power cables available, which were bundled together and had 6+2 connectors. The card required one 8-pin connector. I plugged in the 6-pin connector from one cable and the 2-pin connector from the other.

Since I fixed this, no errors.

There's still an issue with this system. The reason I am running 3 sieving reservations on each card is that I can't get the expected performance without doing that. Running one or two sieving tasks per card, I get just under 170P/day for each task. Running three per card, performance is slightly less per task, which puts it in line with expectations.

Still trying fo figure that out.

I think you should reduce your clock and memory speeds. Those errors look like what comes up and happens when the card is pushed to it's limits. Reduce it a bit and see if the errors go away.

I learned, from Azmodes, if you get errors like that reduce clocks and memory till they go away. You can adversely increase clocks till those errors occur then reduce till they subside. We learned for sieving high clock speed is best obviously but low memory is also fine and doesn't affect sieving performance.


Will try that if needed, but I havn't overclocked these cards, and one is definitely stock clocks (the other came with the system. Also, the errors are occurring on both cards. Will at least reinstall drivers first.

It really seems to act like a memory leak -- I stopped and restarted all sieving tasks last night, and no problems so far (maybe 20-22 hours).

Update:

Just checked and had the same error on three instances and a different one on one instance:

Error clGetEventInfo on device 1 (131.7P/day) Found 6465 ETA 42h22m
Error code -5, message: Out of resources
GPU Error -5 @ 2365: Out of resources

Ran out of GPU RAM, maybe?

If not, are utilities like DDU worth trying, or should I just go straight to a clean OS install (just a crunchbox at this point, sothat's just an annoying expenditure of time)?


DDU is definitely worth trying before resorting to a full OS install.
In your case the install difficulty is minimal, but still time consuming. DDU would be a minimal time investment that could prevent a further time investment in an OS reinstall.


OK -- I'll try that first if the driver reinstall doesn't resolve the problem.

OK -- thinking about it, I had something weird on this system before (driven from my mind by problems with another system since). At the beginning of this month, when I first started running manual sieving on this system, when I ran the application it would report that the system ahd 4 RTX 2070s, not 2. Only 2 showed up in Device manager. Reinstalling drivers got rid of that, although I think I had to do it a couple of times. I'm going to try a clean installation of the latest drivers and see if that fixes this.

I have begun getting errors like this on the system that I have running manual sieving:

Error clEnqueueWriteBuffer on device 20P/day) Found 713 ETA 39h00m
Error code -36, message: Invalid command queue
GPU Error -36 @ 2426: Invalid command queu

The errors are occurring on this system, running six instances of GFN-18 manual sieving. It seems to happen to two instances at a time, sometimes on the same card and sometimes not. They restart just fine. The interval between occurrences seems to be hours.

Any ideas what is going on?
