Message 29135 - Posted: 11 Dec 2010 | 12:37:39 UTC

Hi,

Firstly, I'm very new to using the GPU for crunching numbers, so please answer in very basic terms. I won't feel offended :-)

http://www.primegrid.com/show_host_detail.php?hostid=173115

All my GPU tasks are coming up with 'computation error'.

I've done the suggested items in http://www.primegrid.com/forum_thread.php?id=2845&nowrap=true#28527, but then BOINC said I had no GPU at all!. I've since rolled back my driver.

Any suggestions?

Thanks

Bernie

The problem is you gpu "CAL ATI Radeon HD 2300/2400/3200 (RV610) (336MB) driver: 1.4.880".
IIRC, OpenCL is not supported on that GPU.

nVidia uses also "CAL ATI"?
