Have you installed ECC memory on your AMD Ryzen or Intel Core platform and are unsure if it’s functioning? Here’s a quick method to verify its operation using Windows and CPU-Z, particularly useful amidst busy weeks.
Verifying ECC Functionality with CPU-Z
Older methods like using wmic to check are outdated; they yield inconsistent results, particularly with Intel Xeon and AMD Threadripper systems. Instead, CPU-Z provides a more reliable approach, and the first step is to download the application.
Once you have CPU-Z, you may notice that simply opening the program won’t display information about ECC memory. In our example, we’re using a Minisforum MS-A2 with ECC DDR5 SODIMMs.
To check for ECC:
- Open CPU-Z.
- Navigate to the “Tools” button at the bottom and generate a report, opting for a text output instead of HTML.
Then look for “DMI Physical Memory Array” and “DMI Memory Device” in the report. Search for the term “correction.” If the report shows “None,” it suggests ECC isn’t active. However, you’ll still be able to observe that the total width is 72 bits, with a data width of 64 bits, confirming the presence of ECC-supported modules: 48GB DDR5-5600 SODIMMs in this case.
