Device Memory allocation is different in nsight Eclipse and netbeans

Below is the written code I am executing in nsight eclipse and Netbeans. I am getting different memory allocation size. I am not able to understand why it is happening. If anyone has any clue please help.

int main()
{
    cuComplex *a,*b;
    float *c;
    double mfree,mtotal;
    size_t mem1,mem2;
    int Size = 8192;
    cudaMalloc((void**)&a,sizeof(cuComplex)*Size*Size);
    cudaMalloc((void**)&b,sizeof(cuComplex)*Size*Size);
    cudaMalloc((void**)&c,sizeof(float)*Size*Size);

    cudaMemGetInfo(&mem1,&mem2);
    mfree = (double)mem1/1024*1024;
    mtotal = (double)mem2/1024*1024;

    printf("Total memory = %f and Free Memory = %f",mtotal,mfree);
}

Below is the output in both platforms

Output in Nsight Eclipse

Total memory = 2001.8125 and Free Memory = 105.625

Output in Netbeans

Total memory = 2001.8125 and Free Memory = 572.125
