Determining the manufacturer of your computer's RAM

Hello,

Reading the At least some of its DRAM products are indeed defective, admits SK Hynix article made me realize that people might need a quick way to identify the manufacturer of the memory modules installed in their computer. 

 

While you can definitely find this out by opening up your computer to physically examine the memory, or by running a third-party utility like CPU-Z, it is not always convenient to open a computer to look inside, nor is it always possible to install third-party software.  Also, if you are managing multiple computers, you might want to use something that's built into Windows and can be scripted.

Although it is being deprecated, the Windows Management Instrumentation (WMI) Command Line Utility (filename: WMIC.EXE) allows you to query the system for various types of information about the computer, including the type of memory installed in it.

 

With that in mind, I came up with the following line to check the relevant information about a computer's installed memory.  It can be run from a standard Windows Command Prompt (filename: CMD.EXE) :

 

wmic memorychip get manufacturer, otheridentifyinginfo, partnumber, serialnumber, sku

 

So what exactly does this command do?  It calls the WMIC command with the memorychip alias (setting), and then to get the following properties from it:

 

manufacturer - the manufacturer of the installed memory module

otheridentifyinginfo - blank for the RAM I tested with, but may provide information

partnumber - the part number of the installed memory module

serialnumber - the serial number of the installed memory module

sku - blank for the RAM I tested with, but may provide you with the SKU (stock keeping unit) of the installed memory module

 

Depending upon the manufacturer of your memory, not all of these fields may be present.  To see all the different properties available that you can query, issue the following command:

 

wmic memorychip get /?

 

Or, if you want to view them all:

 

wmic memorychip list full

 

If you do the "get all" query, you may wish to redirect the output to a text file, otherwise you are going to be presented with a lot of information.

 

Regards,

Is there a Manufacturer lookup list, which gives you a friendly name? Mine say "01980000802C"

`get all` doesn't work, `list full` works better

Same thing here, just a different number/letter combo. 

 

Could just run....

 

wmic memorychip get devicelocator, partnumber

 

The output from my notebook is ...

 

DeviceLocator  PartNumber
DIMM A         8ATF1G64HZ-2G6E1
DIMM B         8ATF1G64HZ-2G6E1

 

From there it's a google search which tells me they are Micron 8GB modules.

Hello,

 

Thank you for the suggestion, @spikey_richie.  I'm not aware of anything like a memory manufacturer lookup list, but perhaps by typing the results into a search engine will reveal the manufacturer's name.
