size of global memory

I have an ATI Radeon HD5970 GPU which is supposed to have 1GB of memory. However, querying CL_DEVICE_GLOBAL_MEM_SIZE tells me that I only have 256MB of memory. I read that this is a common bug:

I thought that although the value of this query is wrong, I would still be able to allocate 1GB of main memory. However, when allocating 2 buffers of size 256MB, for example, the error code CL_MEM_OBJECT_ALLOCATION_FAILURE is returned...

Does anyone have the same problem?
