Question:

How do I get the amount of RAM installed on a system and display it in megabytes?

Answer:

You can determine this with the Win32 function GlobalMemoryStatus(). See the little function below.

program dummy;

uses
  Dialogs, Windows, SysUtils;

function DisplayRam : String;
var
  Info: TMemoryStatus;
begin
  Info.dwLength := sizeof(TMemoryStatus);
  GlobalMemoryStatus(Info);
  Result := Format('%d MB RAM', [(Info.dwTotalPhys SHR 20) + 1])
end;

begin
  ShowMessage(DisplayRam)
end.
