How do I get total physical memory size using PowerShell without WMI

Question

I m trying to get the physical memory size using PowerShell  but without using get-wmiobject   I have been using the following PS cmdlet to get the physical memory size  but the value changes with each new poll    get-counter -counter   Memory Available Bytes   CounterSamples 0  CookedValue     get-counter -counter   Memory Committed Bytes   CounterSamples 0  CookedValue   In general  this gives me a value around  8605425664 bytes  I m also testing the value I get from adding these counters with the returned value from    get-wmiobject -class  win32 physicalmemory  -namespace  root CIMV2   Capacity   This gives me the value  8589934592 bytes  So  not only is the total physical memory calculated from counters changing  but it s value differs from the WMI value by a couple megabytes  Anyone have any ideas as to how to get the physical memory size without using WMI

Maybe not the best solution  but it worked for me    System Reflection Assembly   LoadWithPartialName  Microsoft VisualBasic    VBObject  Microsoft VisualBasic Devices ComputerInfo   new    SystemMemory  VBObject TotalPhysicalMemory

Id like to say that instead of going with the systeminfo this would help over to get the total physical memory in GB s the machine   Get-CimInstance Win32 PhysicalMemory   Measure-Object -Property capacity -Sum   Foreach    0 N2   -f   math   round     Sum   1GB  2      you can pass this value to the variable and get the gross output for the total  physical memory in the machine       totalmemory   Get-CimInstance Win32 PhysicalMemory   Measure-Object -Property capacity -Sum   Foreach    0 N2   -f   math   round     Sum   1GB  2        totalmemory

I d like to make a note of this for people referencing in the future    I wanted to avoid WMI because it uses a DCOM protocol  requiring the remote computer to have the necessary permissions  which could only be setup manually on that remote computer    So  I wanted to avoid using WMI  but using get-counter often times didn t have the performance counter I wanted   The solution I used was the Common Information Model  CIM   Unlike WMI  CIM doesn t use DCOM by default  Instead of returning WMI objects  CIM cmdlets return PowerShell objects    CIM uses the Ws-MAN protocol by default  but it only works with computers that have access to Ws-Man 3 0 or later  So  earlier versions of PowerShell wouldn t be able to issue CIM cmdlets   The cmdlet I ended up using to get total physical memory size was   get-ciminstance -class  cim physicalmemory          Capacity

For those coming here from a later day and age and one a working solution    Get-WmiObject -class  cim physicalmemory    Measure-Object -Property Capacity -Sum  Sum   this will give the total sum of bytes    bytes    Get-WmiObject -class  cim physicalmemory    Measure-Object -Property Capacity -Sum  Sum   kb    bytes   1024  mb    bytes   1024   1024  gb    bytes   1024   1024   1024   I tested this up to windows server 2008  winver 6 0  even there this command seems to work

If you don t want to use WMI  I can suggest systeminfo exe  But  there may be a better way to do that    systeminfo   Select-String  Total Physical Memory    ToString   Split      1  Trim

This gives you the total amount from another WMI class    cs   get-wmiobject -class  Win32 ComputerSystem   Mem    math   Ceiling  cs TotalPhysicalMemory   1024   1024   1024    Hope this helps
