RE: [GD-Windows] How to determine total physical memory available ?

[Carsten O. <car...@se...>]

IIRC, GlobalMemoryStatus returns the actual amount of RAM minus the
DOS-inherited 640 kB base memory.
After actually checking that: Yep, add 640 kB (=3D655360 byte) to the
value in xMS.dwTotalPhys and you got the real value.
When doing anything of this kind, please consider using =
GlobalMemoryStatusEx
on Win2k/XP systems. We're not that far from systems having the full 4GB
space equipped.
