Still wacking away at trying to get GPU rendering working again. Tried a simple scene in SLG tonight, and at least it boots up, but all I get is the ol' black screen. 

Here's the last few lines of the SLG portion with the error

[SLG] [PathOCLRenderThread::0] Compiling kernels

[SLG] [PathOCLRenderThread::0] Kernels not cached

[SLG] [PathOCLRenderThread::0] Compiling Init Kernel

[SLG] [PathOCLRenderThread::0] Rendering thread ERROR: clEnqueueNDRangeKernel(CL_MEM_OBJECT_ALLOCATION_FAILURE)

Again, tried at 0, 1-5, then 64. Still no go. Is anyone else having success with their cards in SLI?

Also found this a bit further up the log:

Tried raising the OpenCL to 512, but its maxed out at 256. Still no go.

Paolo, thoughts?
