    Hi, I've been having few computation errors lately in GPU related tasks and I would like to know what caused it. I've overclocked my GPU today and I think that this could be the possible cause.

      Remove the overclock and if the errors stop then you will know!

       

      Cheers,
      Gary.

        Thanks, I have overclocked it a bit better and everything seems normal again.

          All my GPU tasks are getting computation errors. Default clocks used on both GPU's (nVidia GTX 1650+GT 710, both Gigabyte cards).

          Task is either dropped (changed to 100%) or restarted at some point after reaching 50% of progress. The highest value I've seen is 99% before failing.

           

          One interesting thing is that both my GPU's perform at the very same speed, while they shouldn't.

           

          Using BOINC 7.16.11

            Hi, I am getting massive computation errors from Gamma-Ray GPUs on an intermittent basis.

            Here is an example: https://einsteinathome.org/task/1124476209

            It is on this machine.

            65 (0x00000041) Unknown error code

            Any ideas?

              GPU tasks work fine and performance differ significant between the GPU's in other projects (like those from MilkyWay@Home).

                Just some thoughts of mine:

                Please consider that the NVIDIA GT710 has "only" 2GB VRAM -- which will not be sufficient for GW-GPU-WUs.

                Also the driver does not "officially" support both GPUs.

                And be aware, that MW and EH handle "computations" differently.

                To check things, I would pull the GT710, re-install the GTX1650 driver (don't forget to do a clean driver install each time), and see if the GW-WUs run OK.

                Then do the same the other way around -- pull the GTX1650 and soley try the GT710 with the installed driver, if not OK try the re-installing the correct GT710 driver ...

                  Just a vague idea:

                  Hope you are not using a driver version higher than 21.3.2 ?

                  There are posts about this cruising around ...

                    nVidia are using the very same driver for both cards. It works with other projects.

                      But you missed the part about the 2GB VRAM issue for GW WUs.

                      Your tasks (WUs) that use the 1650 are validating OK.

                      The trouble you have is with the "mini" 710.

                       

                      "Other" projects don't need more than 2GB VRAM GPUs.

                      Have a nice day ...

                        It's officially supported for both. check the supported GPUs chart in the release notes for his driver (446.14)
