[6/4/11 12:24:51 PM] Using Apple OpenCL 1.0 (Dec 23 2010 17:30:26)
[6/4/11 12:24:51 PM] Added GeForce 320M (#1) (6 CU, local work size of 64)
442/619 khash/sec

You should get about 6 mhash. Try a higher -w value, Apple's OpenCL implementation is extremely buggy.

Thanks. Whenever I try a -w setting of 256 or higher, the miner seems to have trouble (lots of OpenCL errors),and still is in that sub 800 khash range

I can imagine higher, its not valid for most GeForces (or any Radeon for that matter). What does local work size say when you don't use -w? That is your maximum.


I get 6.5 khps on my mac air 11", OSX 10.6.7, GeForce 320M. I leave DM vanilla, and it reports a worksize of 512 (!). Never overheats, either, and 3xfaster than my mac pro on DM no flags. But then the desktop on the air is completely unusable and on the pro there's no lag.
