Windows 10: Memory ID-ECC or non-ECC?

I thought I had 16GB of RAM, but two of my four cards are only 1 GB. I'd like to replace them but I can't recall whether I have ECC or non-ECC RAM. Is there an easy way to check?

Unless it is in a server, it is 99% going to be non-ECC

Hi there

run the following from command or powershell to determine the memory type installed...

"wmic memphysical get memoryerrorcorrection" no quotes

The returned code is the type of memory installed: Key Below...

0 (0x0) Reserved
1 (0x1) Other
2 (0x2) Unknown
3 (0x3) None
4 (0x4) Parity
5 (0x5) Single-bit ECC
6 (0x6) Multi-bit ECC
7 (0x7) CRC

Hmm.. I get "No Instance(s) available" when I run that command.

Just tried the same command on 5 separate systems with results as expected.
Used this command for many years and never seen "No Instance(s) available" before...

Can you run "wmic MEMORYCHIP get DataWidth,TotalWidth" no quotes
If the TotalWidth value is larger than the DataWidth value you have ECC memory.

The first method however is more reliable.

I ran it and got a "3", so it's non-ECC.

My workstation can take either ECC or non-, but not both at once. I think it came with ECC, but only 4GB worth.

Good to see that you have the answers required.

Hmm.. get the same thing. My WMI database must be corrupted or something. It works on a different system, so it must be my main box.

Oh well, I've been meaning to do a clean install on that for a while..

it happens, good luck with the reinstall
