Win32_PhysicalMemory Class

The Win32_PhysicalMemory class represents a physical memory device located on a computer system as available to the operating system.
Namespace value is root/CIMV2.
WMI Provider value is CIMWin32.


Properties

  • BankLabel
  • A string identifying the physically labeled bank where the memory is located - for example, 'Bank 0' or 'Bank A'.

  • Capacity
  • The total capacity of this physical memory, in bytes.

  • Caption
  • The Caption property is a short textual description (one-line string) of the object.

  • CreationClassName
  • CreationClassName indicates the name of the class or the subclass used in the creation of an instance. When used with the other key properties of this class, this property allows all instances of this class and its subclasses to be uniquely identified.

  • DataWidth
  • Data width of the physical memory, in bits. A data width of 0 and a total width of 8 would indicate that the memory is solely used to provide error correction bits.

  • Description
  • The Description property provides a textual description of the object.

  • DeviceLocator
  • The DeviceLocator property indicates the label of the socket or circuit board that holds this memory.
    Example: SIMM 3

  • FormFactor
  • The implementation form factor for the chip.For example, values such as SIMM (7), TSOP (9) or PGA (10) can be specified.

  • HotSwappable
  • A physical component can be hot swapped if it is possible to replace the element with a physically different but equivalent one while the containing package has power applied to it (i.e., is 'on'). For example, a fan component may be designed to be hot swapped. All components that can be hot swapped are inherently removable and replaceable .

  • InstallDate
  • The InstallDate property is datetime value indicating when the object was installed. A lack of a value does not indicate that the object is not installed.

  • InterleaveDataDepth
  • The InterleaveDataDepth property indicates the maximum number of consecutive rows of data that are accessed in a single interleaved transfer from the memory device. If the value is 0, then the memory is not interleaved.

  • InterleavePosition
  • The position of this physical memory in an interleave. 0 indicates non-interleaved. 1 indicates the first position, 2 the second position and so on. For example, in a 2:1 interleave, a value of '1' would indicate that the memory is in the 'even' position.

  • Manufacturer
  • The name of the organization responsible for producing the physical element. This may be the entity from whom the element is purchased, but this is not necessarily true. The latter information is contained in the Vendor property of CIM_Product.

  • MemoryType
  • The type of physical memory.

  • Model
  • The name by which the physical element is generally known.

  • Name
  • The Name property defines the label by which the object is known. When subclassed, the Name property can be overridden to be a Key property.

  • OtherIdentifyingInfo
  • OtherIdentifyingInfo captures additional data, beyond asset tag information, that could be used to identify a physical element. One example is bar code data associated with an element that also has an asset tag. Note that if only bar code data is available and is unique/able to be used as an element key, this property would be NULL and the bar code data used as the class key, in the tag property.

  • PartNumber
  • The part number assigned by the organization responsible for producing or manufacturing the physical element.

  • PositionInRow
  • Specifies the position of the physical memory in a 'row'. For example, if it takes two 8-bit memory devices to form a 16-bit row, then a value of '2'means that this memory is the second device. 0 is an invalid value for this property.

  • PoweredOn
  • Boolean indicating that the physical element is powered on (TRUE), or is currently off (FALSE).

  • Removable
  • A physical component is removable if it is designed to be taken in and out of the physical container in which it is normally found, without impairing the function of the overall packaging. A component can still be removable if power must be 'off' in order to perform the removal. If power can be 'on' and the component removed, then the element is removable and can be hot swapped. For example, an upgradeable processor chip is removable.

  • Replaceable
  • A physical component is replaceable if it is possible to replace (FRU or upgrade) the element with a physically different one. For example, some computer systems allow the main processor chip to be upgraded to one of a higher clock rating. In this case, the processor is said to be replaceable . All removable components are inherently replaceable .

  • SerialNumber
  • A manufacturer-allocated number used to identify the PhysicalElement.

  • SKU
  • The stock keeping unit number for this physical element.

  • Speed
  • The speed of the physical memory, in nanoseconds.

  • Status
  • The Status property is a string indicating the current status of the object. Various operational and non-operational statuses can be defined. Operational statuses are "OK", "Degraded" and "Pred Fail". "Pred Fail" indicates that an element may be functioning properly but predicting a failure in the near future. An example is a SMART-enabled hard drive. Non-operational statuses can also be specified. These are "Error", "Starting", "Stopping" and "Service". The latter, "Service", could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is on-line, yet the managed element is neither "OK" nor in one of the other states.

  • Tag
  • The Tag property contains a string that uniquely identifies the physical memory device represented by an instance of Win32_PhysicalMemory.
    Example: Physical Memory 1

  • TotalWidth
  • Total width, in bits, of the physical memory, including check or error correction bits. If there are no error correction bits, the value in this property should match that specified for the DataWidth property.

  • TypeDetail
  • The TypeDetail property indicates the type of physical memory represented by Win32_PhysicalMemory.

  • Version
  • A string indicating the version of the physical element.
