This is why I post :)

Why do you square 1024 in the line: $totalMem /=1024*1024;

headway)


I don't think you are doing it right.  I have 2 512Meg cards on this 
laptop (Dell Latitude D800 WindowsXP) (total = 1Gig), and this script 
tells me I have 512Meg of memory.  By coincidence, it works correctly on 
a Win2003 desktop with 512Meg of memory (maxcap = 2097152, memdev == 
4).  MaximumCapacity is the largest capacity that computer could have 
with the current memory array.  MemoryDevices is the number of slots 
available.  You are computing the average memory card size which would 
work show physical memory IF you have only 1 card.  Hmm, no - that's not 
right either because I think the desktop has 2 256Meg cards.

I think you really need something like this:
#!/bin/perl -w

use Win32::OLE qw(in with);

my $host = shift @ARGV;

$WMI = Win32::OLE->new('WbemScripting.SWbemLocator') || die "Cannot access
WMI on local machine: ", Win32::OLE->LastError;

$Services = $WMI->ConnectServer($host) || die "Cannot access WMI on remote
machine: ", Win32::OLE->LastError;

$ComputerSysSet = $Services->InstancesOf("Win32_PhysicalMemory");

my $totalMem = 0;
foreach $ComputerSystem (in($ComputerSysSet)) {
    $totalMem += $ComputerSystem->{'Capacity'};
}
$totalMem /=1024*1024;
print "There is $totalMem MegaBytes of memory on this system\n";

exit 0;
