Hi! I could appreciate some help.

 

I have a 280x aka tahiti gpu with 3gb memory.

the max_mem_alloc_size is 512mb.

 

Howewer if i try to create a buffer above ~250mb, clenqueuewritebuffer fails with error code -4: clEnqueueWriteBuffer returns CL_MEM_OBJECT_ALLOCATION_FAILURE;

 

For testing purposes its the only buffer i use, so memory limit coudnt be a problem.

 

Im using 13.9 whql driver. sdk 2.9.1.

 

Is it a bug, or something i didn't know about?

 

Help me please. Thank you!
