Kaveri - global mem size

Hi,

 

I use openCL on A10-7850k Kaveri GPU in 64 bit address mode. When I query global mem size like this:

 

cl_ulong globalSize;
clGetDeviceInfo(m_deviceId, CL_DEVICE_GLOBAL_MEM_SIZE, sizeof (globalSize), &globalSize, 0);

 

then it shows 512 MB global memory. But in reality I can use much more memory, at least with CL_MEM_USE_HOST_PTR.

Am I misinterpreting something?
