Beginning with Windows Server 2008 and Windows Vista SP1, the Windows Hardware Error Architecture (WHEA) uses the tidPlatformMemoryError data template to report the hardware error data that is associated with platform memory WHEA hardware error events that are logged in the system event log. The tidPlatformMemoryError data template is defined as follows:

<template tid="tidPlatformMemoryError">
  <data name="FRUId" inType="win:GUID"></data>
  <data name="FRUText" inType="win:AnsiString" length="20"></data>
  <data name="ValidBits" inType="win:HexInt64" outType="win:HexInt64"></data>
  <data name="ErrorStatus" inType="win:HexInt64" outType="win:HexInt64"></data>
  <data name="PhysicalAddress" inType="win:HexInt64" outType="win:HexInt64"></data>
  <data name="PhysicalAddressMask" inType="win:HexInt64" outType="win:HexInt64"></data>
