I switched my GPUs to Collatz last night, and the nVidia card is pumping the SOLO_Collatz out awesome - around 32 mins each.
However, something is up again with this HD 5870. I noticed I got OpenCL collatz WUs on it, so maybe that is the problem? They are NOT Solo_Collatz, just the regular ATI Collatz is what I have checked in my preferences (I couldn't get the solo ones to work either) and when I check my computer, I've got a Collatz OpenCL WU that has been running for 7 hours and 15 mins, and it's only 29% completed! Shows my GPU load at 98%. If I suspend it and try another, one, I get the same slow results judging by how slow the % complete goes up. Wonder what's going on?
Do you guys think I need to change the drivers or reset the project on this computer or ??? I'm out of ideas...
Thanks for the help.
