1) Message boards : Problems and Help : Not getting tasks - could you please check? (Message 83595)
Posted 1984 days ago by far
I changed GPU's from a 7970 to R9 290, and aborted the task queue that was there in case they were specific to the old GPU.

I've rebooted, updated project, reset project detached and reattached and it won't get any tasks.
In the message logs it can see the OpenCL 2.0 drivers and on the computer/account you can see it also recognizes the GPU.

The machine is 483509.

Could you please have a look/suggest what to try?

Thanks for the reply. The 6*** AMD cards have ended up on this project cause it is most stable for them (less lockups or bsod's). So unlucky for me it is so much less efficient.

I rechecked the 4870X2 and there is screen after screen all 12000-14000s so yeh bye bye to that card. No idea why it's so much more inefficient for me than your history :-(

I've got a few machines running PPS/Sieve using ATI cards and they are massively slower than one with an nvidia 660ti (also running PPS/Sieve) - both on GPU.

eg for their 3371 credit they take:
4870X2: 12,000 - 14,000 seconds
6970/6990: 2,800s
7970: 2,100 - 2,900s
66ti: only 750s!!!

Probably I am missing something? Or does the cuda version run more efficiently? They all use 7.0.28 boinc and current graphics drivers (except the 4870x2 cause opengl causes it to fail).

Thanks, far
