参考NvAPI_GPU_GetRamType，这个API是未公开的
https://github.com/processhacker/plugins-extra/blob/master/NvGpuPlugin/nvidia.c
大概用法是
加载nvapi64.dll/nvapi.dll，获取nvapi_QueryInterface的地址，
使用nvapi_QueryInterface(0x57F7CAACUL)取得NvAPI_GPU_GetRamType的地址，
其中NvAPI_GPU_GetRamType有两个参数，第一个入参为GPU句柄，第二个出参为内存类型，定义如下
显示类型 第二个参数的返回值
Unknown 0
SDRAM 1
DDR1 2
DDR2 3
GDDR2 4
GDDR3 5
GDDR4 6
DDR3 7
GDDR5 8
LPDDR2 9
GDDR5X 10
