OK, I read your post on the project forum. My first guess, is that the HD 4850 does not have full built-in support for OpenCL but only a very small subset of the OpenCL code. ATI did not completely embrace OpenCL until the 5xxx series. Anyhoot, me thinks this is the culprit.
I assume, then, the newest drivers might cure the problem? or do I need the skd...sdk...thingy too? Yeah, I know something, but just enough to get me in trouble....usually....Al
No worries mate, glad to help. I also have an HD 4850 but haven't crunched MW in months. If MW is a priority for you then yes try the current driver with the SDK & OpenCL support. Please note that I have never been able to do MW with the OpenCL drivers. Kept having issues so I gave up. Now that card is crunching Collatz and is getting really decent credit. I have the GPU clock set at 625Mhz to limit the heat output since it's now in my Uncle's computer.
Upgraded to the latest drive SDK and Catalyst and all wu fail within 3 - 5 seconds....weird!!! Reverted back and, still, only the free ones fail. I'll leave it the way it is.:confused:
Ah, yes. Now it comes back to me. That had been my experience running MW on my 4850.Quote:

That box is a Win xp 32 system. Going back to the older drivers fixed all wu failing, but the ps_separation_xx_xx_free still fail every time.

I know that feeling and I am not the only one
Damn ring always failing
Aha you were talking about the RIG not the Ring. Always wrong, always wrong. Let it be both failed.

Huh. Something is definitely wrong, because we have two 4870s in Kat's rig, and she is cranking on MW with them - no errors yet after about 10 days. The rig is running Win7 64bit with the latest Catalyst drivers.
