The WMI Service object on windows is very powerful, it allows us to list memory devices easily by retrieving information via query, which looks like SQL. The query to list memory devices is:
Select * from Win32_MemoryDevice
With VBScript, the code snippet is:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | ' List Memory Devices On Error Resume Next strComputer = "." Set objWMIService = GetObject("winmgmts:" _ & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2") Set colItems = objWMIService.ExecQuery("Select * from Win32_MemoryDevice") For Each objItem in colItems Wscript.Echo "Device ID: " & objItem.DeviceID Wscript.Echo "Ending Address: " & objItem.EndingAddress Wscript.Echo "Starting Address: " & objItem.StartingAddress Wscript.Echo Next |
' List Memory Devices
On Error Resume Next
strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colItems = objWMIService.ExecQuery("Select * from Win32_MemoryDevice")
For Each objItem in colItems
Wscript.Echo "Device ID: " & objItem.DeviceID
Wscript.Echo "Ending Address: " & objItem.EndingAddress
Wscript.Echo "Starting Address: " & objItem.StartingAddress
Wscript.Echo
NextOn my Lenovo M900 Workstation, the results are (32GB RAM).
Device ID: Memory Device 0 Ending Address: 8388607 Starting Address: 0 Device ID: Memory Device 1 Ending Address: 25165823 Starting Address: 16777216 Device ID: Memory Device 2 Ending Address: 16777215 Starting Address: 8388608 Device ID: Memory Device 3 Ending Address: 33554431 Starting Address: 25165824
Of course, you can also do the same in Microsoft JScript (as long as it runs under Windows Scripting Host) or other scripting languages.
