如何检索内存类型（ rdimm 或 udimm）？

有没有办法知道安装的内存是Registered DIMM 还是Unregistered DIMM？这win32_物理内存似乎没有提供此信息？

您可以找到有关 udimm rdimm 的更多信息here

EDIT : the solution provided by @C.B doesnt work either

第一个想法是使用WMIWin32_PhysicalMemory并测试TotalWidth（包括校验位的位数）是否大于DataWidth（不包括校验位的位数）。

    gwmi Win32_PhysicalMemory | select totalwidth, datawidth, banklabel | 
 % {
 if ( $_.totalwidth > $_.datawidth )
 {
    "$($_.banklabel) is ECC memory type"
 }
 else
 {
    "$($_.banklabel) is non-ECC Memory Type"
 }
 }

我不知道是否存在最好的方法，检查内存是否是 ECC。

尝试检查缓冲/注册或非内存类型：

$a = Get-WMIObject -Class "Win32_PhysicalMemoryArray"

 Switch ($a.MemoryErrorCorrection) {
                    0 {Write-Host "ECC Type....:  Reserved"}
                    1 {Write-Host "ECC Type....:  Other"}
                    2 {Write-Host "ECC Type....:  Unknown"}
                    3 {Write-Host "ECC Type....:  None"}
                    4 {Write-Host "ECC Type....:  Parity"}
                    5 {Write-Host "ECC Type....:  Single-bit ECC"} #unbuffered
                    6 {Write-Host "ECC Type....:  Multi-bit ECC"}  #registed
                    7 {Write-Host "ECC Type....:  CRC"}
                }
