How to check my RAM configuration (Windows 7)?

I would like to check my RAM configuration.

I know it is easy to check the total RAM installed on a computer (eg 32 GB), but is there an easy way to check in Windows if the RAM is e.g. 2x16 GB, 4x8 GB, 8x4 GB or 16x2 GB?

If you don't mind using the command line, WMI can do this and is native with Windows XP and newer.

Simply run wmic MEMORYCHIP get BankLabel,DeviceLocator,Capacity,Tag

>wmic MEMORYCHIP get BankLabel,DeviceLocator,Capacity,Tag
BankLabel  Capacity    DeviceLocator            Tag
BANK 0     2147483648  Bottom - Slot 1 (top)    Physical Memory 0
BANK 1     4294967296  Bottom - Slot 2 (under)  Physical Memory 1

(DeviceLocator will likely give you DIMM numbers on a desktop machine - the top/under slots are because I'm on a laptop. Both BankLabel and DeviceLocator formats may vary by machine.)

There is a lot more data available, but it doesn't display well in the limited columns of a command prompt. You can export it all to a text file for easier viewing (don't forget to turn off word wrap):

>wmic MEMORYCHIP get >data.txt
>start data.txt

And you can use those extra columns to customise the first command to give you, e.g., the manufacturer name, product number and serial number.

Yes, there a way to do this since CPU-Z can display that information. If if one program can do that then so can others.

Edit:

For linux: DMIdecode
For windows: wmic MemoryChip` as already answered by Bob.

You can use Powershell and get WMI Object, like the wmic command in CMD, except you can output it to a table using GridView.

Lots of information too, and no need to download/install any software!

Get-WmiObject CIM_PHYSICALMEMORY | Out-GridView

Go to http://www.crucial.com, select the middle tab "system scanner" and run the plug-in. It will tell you the complete description of your memory configuration and the possible upgrades as well. It also give you other details related your motherboard, pc specific model, etc.
