Checking the type and size of RAM with Windows PowerShell

I subscribe to the PowerTip of the day email of and I got this tip today. If you want to know the type and size of RAM your PC uses, and available banks, you can use the following script:

$memorytype = "Unknown", "Other", "DRAM", "Synchronous DRAM", "Cache DRAM",
"EDO", "EDRAM", "VRAM", "SRAM", "RAM", "ROM", "Flash", "EEPROM", "FEPROM",
$formfactor = "Unknown", "Other", "SIP", "DIP", "ZIP", "SOJ", "Proprietary",
"QFP", "TQFP", "SOIC", "LCC", "PLCC", "BGA", "FPBGA", "LGA"
$col1 = @{Name='Size (GB)'; Expression={ $_.Capacity/1GB } }
$col2 = @{Name='Form Factor'; Expression={$formfactor[$_.FormFactor]} }
$col3 = @{Name='Memory Type'; Expression={ $memorytype[$_.MemoryType] } }

Get-WmiObject Win32_PhysicalMemory | Select-Object BankLabel, $col1, $col2, $col3

The output would be something like:

BankLabel                     Size (GB) Form Factor         Memory Type
---------                     --------- -----------         -----------
                                      2 DIMM                DDR-2
                                      2 DIMM                DDR-2
                                      2 DIMM                DDR-2
                                      2 DIMM                DDR-2

It works pretty nice, doesn't it?

can you update this to use DDR3 too?

This is helpful. Would you know if there is a similar powershell to get other info about the RAM, such as voltage?
