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!
