Error CL_MEM_OBJECT_ALLOCATION_FAILURE WHEN CALLING clEnqueueNDRangeKernel for Kernel 0.

[Alvinmines]

when I try to add another gpu_threads_conf like this { "index" : 0, "intensity" : 900, "worksize" : 8, "affine_to_cpu" : true }, { "index" : 1, "intensity" : 900, "worksize" : 8, "affine_to_cpu" : true },

I get the error that I wrote in the title, this does not happen if I only use one gpu thread.

But my H/s goes from 500 with one thread to being very unconsistent between 7000 H/s and 17000 H/s The GPU I have in my computer is AMD 7990.

When I run Clinfo this is some of the information given.

This is the config I am using.

Please reduce the intensity for the first gpu. Do you connected the crossfire link between the tw gpus? If so please remove the link cable.

When I reduce the intensity it just makes the 1st one stop, and only the 2nd one mine. I am not using a crossfire link, got any other tips?

I'm also seeing this issue.
