WMI & Win32_LogicalMemoryConfiguration results

[brianashman]

On the W2K Scripting Guide at

http://www.microsoft.com/resources/...00/server/scriptguide/en-us/sas_wmi_dieu.mspx

in listing 6.1 there is a script example for displaying the amount of memory installed in a machine. The results given are in KB. When divided by 1024 to get MB, the answer is not an integer.

I have also found this to be the case on my own machines with XP (SP1) & W2K (SP2). My XP machine has 1280MB, but reports 1309772KB instead of 1310720KB.

What is the cause?

What would be the best way to find the true amount of memory installed?

I have found a better way that gives the EXACT memeory amount:

Set WMI = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
set Results=WMI.ExecQuery("select * from win32_PhysicalMemory")

RAM=0
For Each Memory In Results
RAM=RAM+Memory.Capacity/1024/1024
Next

Brian, I hate to burst your bubble but your script doesn't work.

I have a total of 512 MB and your script only reports 256.

My guess is that if you have more than one memory card your script does not pick it up. I know I have two 256MB SDRAM cards.

My script correctly reports the 512.

I hope you find this post helpful. Please let me know if it was.

Mark
