Very helpful, Checked that I got exactly what I purchased! So glad I didn't use any 3rd party tools for this simple check.

FYI I'm running a gigabyte x570 aorus master rev 1 on the latest bios - F36c and it's working with ECC ram. 5800x3D

Server grade technology always above level. More stable and more powerful. I think cloud technology is the future.

Sweet, thank you. I was looking for a way to check this without having to download and install Aida64.

This checks for ECC ram, but does not verify that it's error checking and logging, aka working. In Windows Event Viewer, you can check for "WHEA-Logger" record when it's working.

Much thanks, I am confused because the both Data Width and Total width are 72, but on the memoryerrorconnection it gives code 3 which is none, do i have a ecc ram or not?

Hi, when I taped "wmic MEMORYCHIP get DataWidth, TotalWidth" it gave me both 64 64 but when I taped "wmic memphysical get memoryerrorcorrection" it gave me number 3 which is none, can you explain to me if it's possible ?

[alexgorbacov]

What if I have both data width and total width at 72? Does my pc simply uses those 6 bits for data and not error correction?

[RTXBhai]

Also could you please help me know how to get RAM Rank and device width like 1Rx8 or 1Rx16 using PowerShell ? Thanks a million, in advance.
