The Win32_SMBIOSMemory abstract WMI class represents the properties of a computer system memory as seen through the system management BIOS (SMBIOS) interface. The SMBIOS interface does not distinguish between nonvolatile, volatile, and flash memories. The CIM_Memory class is the parent class of all types of memory.
Methods
Win32_SMBIOSMemory has no methods. Inherited methods (Reset and SetPowerState) are not implemented.
Properties
Win32_SMBIOSMemory returns 38 properties:
'Access','AdditionalErrorData','Availability','BlockSize','Caption',
'ConfigManagerErrorCode','ConfigManagerUserConfig','CorrectableError','CreationClassName','Description',
'DeviceID','EndingAddress','ErrorAccess','ErrorAddress','ErrorCleared','ErrorData',
'ErrorDataOrder','ErrorDescription','ErrorInfo','ErrorMethodology','ErrorResolution','ErrorTime',
'ErrorTransferSize','InstallDate','LastErrorCode','Name','NumberOfBlocks','OtherErrorDescription',
'PNPDeviceID','PowerManagementCapabilities','PowerManagementSupported','Purpose',
'StartingAddress','Status','StatusInfo','SystemCreationClassName','SystemLevelAddress','SystemName'
Unless explicitly marked as writeable, all properties are read-only. Read all properties for all instances:
Get-CimInstance -ClassName Win32_SMBIOSMemory -Property *
Most WMI classes return one or more instances.
When
Get-CimInstancereturns no result, then apparently no instances of class Win32_SMBIOSMemory exist. This is normal behavior.Either the class is not implemented on your system (may be deprecated or due to missing drivers, i.e. CIM_VideoControllerResolution), or there are simply no physical representations of this class currently available (i.e. Win32_TapeDrive).
Access
Type of access.
Access returns a numeric value. To translate it into a meaningful text, use any of the following approaches:
Use a PowerShell Hashtable
$Access_map = @{
0 = 'Unknown'
1 = 'Readable'
2 = 'Writeable'
3 = 'Read/Write Supported'
4 = 'Write Once'
}
Use a switch statement
switch([int]$value)
{
0 {'Unknown'}
1 {'Readable'}
2 {'Writeable'}
3 {'Read/Write Supported'}
4 {'Write Once'}
default {"$value"}
}
Use Enum structure
Enum EnumAccess
{
Unknown = 0
Readable = 1
Writeable = 2
ReadWrite_Supported = 3
Write_Once = 4
}
Examples
Use $Access_map in a calculated property for Select-Object
<#
this example uses a hashtable to translate raw numeric values for
property "Access" to friendly text
Note: to use other properties than "Access", look up the appropriate
translation hashtable for the property you would like to use instead.
#>
#region define hashtable to translate raw values to friendly text
# Please note: this hashtable is specific for property "Access"
# to translate other properties, use their translation table instead
$Access_map = @{
0 = 'Unknown'
1 = 'Readable'
2 = 'Writeable'
3 = 'Read/Write Supported'
4 = 'Write Once'
}
#endregion define hashtable
#region define calculated property (to be used with Select-Object)
<#
a calculated property is defined by a hashtable with keys "Name" and "Expression"
"Name" defines the name of the property (in this example, it is "Access", but you can rename it to anything else)
"Expression" defines a scriptblock that calculates the content of this property
in this example, the scriptblock uses the hashtable defined earlier to translate each numeric
value to its friendly text counterpart:
#>
$Access = @{
Name = 'Access'
Expression = {
# property is an array, so process all values
$value = $_.Access
$Access_map[[int]$value]
}
}
#endregion define calculated property
# retrieve the instances, and output the properties "Caption" and "Access". The latter
# is defined by the hashtable in $Access:
Get-CimInstance -Class Win32_SMBIOSMemory | Select-Object -Property Caption, $Access
# ...or dump content of property Access:
$friendlyValues = Get-CimInstance -Class Win32_SMBIOSMemory |
Select-Object -Property $Access |
Select-Object -ExpandProperty Access
# output values
$friendlyValues
# output values as comma separated list
$friendlyValues -join ', '
# output values as bullet list
$friendlyValues | ForEach-Object { "- $_" }
Use $Access_map to directly translate raw values from an instance
<#
this example uses a hashtable to manually translate raw numeric values
for property "Win32_SMBIOSMemory" to friendly text. This approach is ideal when
there is just one instance to work with.
Note: to use other properties than "Win32_SMBIOSMemory", look up the appropriate
translation hashtable for the property you would like to use instead.

}
#endregion define hashtable
# get one instance:
$instance = Get-CimInstance -Class Win32_SMBIOSMemory | Select-Object -First 1
<#
IMPORTANT: this example processes only one instance to illustrate
the number-to-text translation. To process all instances, replace
"Select-Object -First 1" with a "Foreach-Object" loop, and use
the iterator variable $_ instead of $instance
#>
# query the property
$rawValue = $instance.Access
# translate raw value to friendly text:
$friendlyName = $Access_map[[int]$rawValue]
# output value
$friendlyName
Use a switch statement inside a calculated property for Select-Object
<#
this example uses a switch clause to translate raw numeric
values for property "Access" to friendly text. The switch
clause is embedded into a calculated property so there is
no need to refer to external variables for translation.
Note: to use other properties than "Access", look up the appropriate
translation switch clause for the property you would like to use instead.

#region define calculated property (to be used with Select-Object)

Use the Enum from above to auto-translate the code values
<#
this example translates raw values by means of type conversion
the friendly names are defined as enumeration using the
keyword "enum" (PowerShell 5 or better)
The raw value(s) are translated to friendly text by
simply converting them into the enum type.
Note: to use other properties than "Win32_SMBIOSMemory", look up the appropriate
enum definition for the property you would like to use instead.
#>
#region define enum with value-to-text translation:

To process all instances, replace "Select-Object -First 1"
with a "Foreach-Object" loop, and use the iterator variable
$_ instead of $instance
#>
# query the property:
$rawValue = $instance.Access
#region using strict type conversion
<#
Note: strict type conversion fails if the raw value is
not defined by the enum. So if the list of allowable values
was extended and the enum does not match the value,
an exception is thrown
#>
# convert the property to the enum **Access**
[EnumAccess]$rawValue
# get a comma-separated string:
[EnumAccess]$rawValue -join ','
#endregion
#region using operator "-as"
<#
Note: the operator "-as" accepts values not defined
by the enum and returns $null instead of throwing
an exception
#>
$rawValue -as [EnumAccess]
#endregion
Enums must cover all possible values. If Access returns a value that is not defined in the enum, an exception occurs. The exception reports the value that was missing in the enum. To fix, add the missing value to the enum.
AdditionalErrorData
Array of octets that hold additional error information. An example is Error Checking and Correcting (ECC) Syndrome, or the return of the check bits if a CRC-based error methodology is used. In the latter case, if a single bit error is recognized and the cyclical redundancy check (CRC) algorithm is known, it is possible to determine the exact bit that failed. This type of data (ECC Syndrome, Check Bit or Parity Bit data, or other vendor supplied information) is included in this field. If the ErrorInfo property is equal to 3 (OK), then this property has no meaning.
Get-CimInstance -ClassName Win32_SMBIOSMemory | Select-Object -Property AdditionalErrorData
Availability
Availability and status of the device.
Availability returns a numeric value. To translate it into a meaningful text, use any of the following approaches:
Use a PowerShell Hashtable
$Availability_map = @{
1 = 'Other'
2 = 'Unknown'
3 = 'Running/Full Power'
4 = 'Warning'
5 = 'In Test'
6 = 'Not Applicable'
7 = 'Power Off'
8 = 'Off Line'
9 = 'Off Duty'
10 = 'Degraded'
11 = 'Not Installed'
12 = 'Install Error'
13 = 'Power Save - Unknown'
14 = 'Power Save - Low Power Mode'
15 = 'Power Save - Standby'
16 = 'Power Cycle'
17 = 'Power Save - Warning'
18 = 'Paused'
19 = 'Not Ready'
20 = 'Not Configured'
21 = 'Quiesced'
}

ErrorInfo
Type of error that occurred most recently. The values 12 through 14 are unused. The ability to be corrected is indicated in the property CorrectableError.
ErrorInfo returns a numeric value. To translate it into a meaningful text, use any of the following approaches:
Use a PowerShell Hashtable
$ErrorInfo_map = @{
1 = 'Other'
2 = 'Unknown'
3 = 'OK'
4 = 'Bad Read'
5 = 'Parity Error'
6 = 'Single-Bit Error'

8 = 'Multi-Bit Error'
9 = 'Nibble Error'
10 = 'Checksum Error'
11 = 'CRC Error'
12 = 'Corrected single-bit error'
13 = 'Corrected error'
14 = 'Uncorrectable error'
}
Use a switch statement

10 {'Checksum Error'}
11 {'CRC Error'}
12 {'Corrected single-bit error'}

clause is embedded into a calculated property so there is
no need to refer to external variables for translation.
Note: to use other properties than "StatusInfo", look up the appropriate
translation switch clause for the property you would like to use instead.
#>
#region define calculated property (to be used with Select-Object)
<#
a calculated property is defined by a hashtable with keys "Name" and "Expression"
"Name" defines the name of the property (in this example, it is "StatusInfo", but you can rename it to anything else)
"Expression" defines a scriptblock that calculates the content of this property
in this example, the scriptblock uses the hashtable defined earlier to translate each numeric
value to its friendly text counterpart:
#>
$StatusInfo = @{
Name = 'StatusInfo'
Expression = {
# property is an array, so process all values
$value = $_.StatusInfo
switch([int]$value)
{
1 {'Other'}
2 {'Unknown'}
3 {'Enabled'}
4 {'Disabled'}
5 {'Not Applicable'}
default {"$value"}
}
}
}
#endregion define calculated property
# retrieve all instances...
Get-CimInstance -ClassName Win32_SMBIOSMemory |
# ...and output properties "Caption" and "StatusInfo". The latter is defined
# by the hashtable in $StatusInfo:
Select-Object -Property Caption, $StatusInfo
Use the Enum from above to auto-translate the code values
<#
this example translates raw values by means of type conversion
the friendly names are defined as enumeration using the
keyword "enum" (PowerShell 5 or better)
The raw value(s) are translated to friendly text by
simply converting them into the enum type.
Note: to use other properties than "Win32_SMBIOSMemory", look up the appropriate
enum definition for the property you would like to use instead.
#>
#region define enum with value-to-text translation:
Enum EnumStatusInfo
{
Other = 1
Unknown = 2
Enabled = 3
Disabled = 4
Not_Applicable = 5
}
#endregion define enum
# get one instance:
$instance = Get-CimInstance -Class Win32_SMBIOSMemory | Select-Object -First 1
<#
IMPORTANT: this example processes only one instance to focus on
the number-to-text type conversion.
To process all instances, replace "Select-Object -First 1"
with a "Foreach-Object" loop, and use the iterator variable
$_ instead of $instance
#>
# query the property:
$rawValue = $instance.StatusInfo
#region using strict type conversion
<#
Note: strict type conversion fails if the raw value is
not defined by the enum. So if the list of allowable values
was extended and the enum does not match the value,
an exception is thrown
#>
# convert the property to the enum **StatusInfo**
[EnumStatusInfo]$rawValue
# get a comma-separated string:
[EnumStatusInfo]$rawValue -join ','
#endregion
#region using operator "-as"
<#
Note: the operator "-as" accepts values not defined
by the enum and returns $null instead of throwing
an exception
#>
$rawValue -as [EnumStatusInfo]
#endregion
Enums must cover all possible values. If StatusInfo returns a value that is not defined in the enum, an exception occurs. The exception reports the value that was missing in the enum. To fix, add the missing value to the enum.
SystemCreationClassName
Value of the scoping computer’s CreationClassName property.
Get-CimInstance -ClassName Win32_SMBIOSMemory | Select-Object -Property SystemCreationClassName
SystemLevelAddress
If TRUE, the address information in the ErrorAddress property is a system-level address. If FALSE, it is a physical address. If the ErrorInfo property is equal to 3 (OK), then this property has no meaning.
Get-CimInstance -ClassName Win32_SMBIOSMemory | Select-Object -Property SystemLevelAddress
SystemName
Name of the scoping system.
Get-CimInstance -ClassName Win32_SMBIOSMemory | Select-Object -Property SystemName

Selecting Properties
To select only some properties, pipe the results to Select-Object -Property a,b,c with a comma-separated list of the properties you require. Wildcards are permitted.
Get-CimInstance always returns all properties but only retrieves the ones that you specify. All other properties are empty but still present. That’s why you need to pipe the results into Select-Object if you want to limit the visible properties, i.e. for reporting.
Selecting Properties
The code below lists all available properties. Remove the ones you do not need:
$properties = 'Access',
'AdditionalErrorData',
'Availability',
'BlockSize',
'Caption',
'ConfigManagerErrorCode',
'ConfigManagerUserConfig',
'CorrectableError',
'CreationClassName',
'Description',
'DeviceID',
'EndingAddress',
'ErrorAccess',
'ErrorAddress',
'ErrorCleared',
'ErrorData',
'ErrorDataOrder',
'ErrorDescription',
'ErrorInfo',
'ErrorMethodology',
'ErrorResolution',
'ErrorTime',
'ErrorTransferSize',
'InstallDate',
'LastErrorCode',
'Name',
'NumberOfBlocks',
'OtherErrorDescription',
'PNPDeviceID',
'PowerManagementCapabilities',
'PowerManagementSupported',
'Purpose',
'StartingAddress',
'Status',
'StatusInfo',
'SystemCreationClassName',
'SystemLevelAddress',
'SystemName'
Get-CimInstance -ClassName Win32_SMBIOSMemory | Select-Object -Property $properties
Limiting Network Bandwidth
If you work remotely, it makes sense to limit network bandwidth by filtering the properties on the server side, too:
Get-CimInstance -Class Win32_SMBIOSMemory -Property $property |
Select-Object -Property $property
Selecting Instances
To select some instances, use Get-CimInstance and a WMI Query. The wildcard character in WMI Queries is % (and not “*”).
The parameter -Filter runs a simple query.
Listing all instances where the property Caption starts with “A”
Get-CimInstance -Class Win32_SMBIOSMemory -Filter 'Caption LIKE "a%"'
Using a WQL Query
The parameter -Query uses a query similar to SQL and combines the parameters -Filter and -Property. This returns all instances where the property Caption starts with “A”, and returns the properties specified:
Get-CimInstance -Query "SELECT Purpose, ErrorAddress, OtherErrorDescription, ErrorCleared FROM Win32_SMBIOSMemory WHERE Caption LIKE 'a%'"
Any property you did not specify is still present but empty. You might need to use
Select-Objectto remove all unwanted properties:Get-CimInstance -Query "SELECT Purpose, ErrorAddress, OtherErrorDescription, ErrorCleared FROM Win32_SMBIOSMemory WHERE Caption LIKE 'a%'" | Select-Object -Property Purpose, ErrorAddress, OtherErrorDescription, ErrorCleared
Accessing Remote Computers
To access remote systems, you need to have proper permissions. User the parameter -ComputerName to access one or more remote systems.
Authenticating as Current User
# one or more computer names or IP addresses:
$list = 'server1', 'server2'
# authenticate with your current identity:
$result = Get-CimInstance -ClassName Win32_SMBIOSMemory -ComputerName $list
$result
Authenticating as Different User
Use a CIMSession object to authenticate with a new identity:
# one or more computer names or IP addresses:
$list = 'server1', 'server2'
# authenticate with a different identity:
$cred = Get-Credential -Message 'Authenticate to retrieve WMI information:'
$session = New-CimSession -ComputerName $list -Credential $cred
$result = Get-CimInstance Win32_SMBIOSMemory -CimSession $session
# remove the session after use (if you do not plan to re-use it later)
Remove-CimSession -CimSession $session
$result
