K20 Global Memory

Accelerated Computing CUDA CUDA Setup and Installation
1

I just received a K20c, with ecc off there is only 1G of global memory showing, With ecc on there is 700K of global memory showing. Im using the cudaGetDeviceProperties call. Also have a gtx 690 in the same box and the properties are correct on that card. Since there is supposed to be 5G of memory on the K20c do I have a defective card ?,

Sorry guys, found the problem, there was no issue other than I forgot to use a %ld in a print statement , memory size was a long int. Reads correct now → Total global memory: 5032706048
