Just realized this is for server boards so let me move this question over to the Server forum for you.
Support Community Manager
Could you please specify what BIOS version is it running on this board?
Since Memtest is not an Intel tool could you please try the following Confidence Test: https://downloadcenter.intel.com/download/25949/EFI-Platform-Confidence-Test-Utility-for-Intel-Server-Systems-and-Intel-Server-Boards-Based-on-the-Intel-Xeon-Processor-E5-1600-2400-2600-4600-v1-and-v2-Product-Families?product=61083
Please share the results

Sorry for the delay in replying.
This is the latest System BIOS - 02.06.0006, which was updated with the EFI FW update Version: 02.06.0006 (Latest) Date: 7/20/2017.
Does the Confidence Test Utility properly test ECC Registered Memory, and in particular for bit fade and Row Hammer?
Thanks for the info provided.
In regards to the particular memory tests that PCT runs I couldn't find the info on the user guide: https://www.intel.com/content/dam/support/us/en/documents/motherboards/server/sb/intelserverboardefipctinstallationandoperatinginst.pdf
I will elevate the question and will let you know as soon we get updates.
Thanks very much for your patience. We finally got a reply from our engineering department.
First about if the PCT tool is able to catch bit fade and Row Hammer looks like it does not. So if memtest found such errors we will trust it.
About the issue itself as you probably guessed it could be either the memory modules or the board itself. The average troubleshooting for this is as usual to make sure the modules are validated first, then try different modules on same board and then try same modules on another S2400SC board (if available). If you are able to try this please let us know the results. Another suggesting would be to run PCT to check the system for defect components installed or incorrect assembling.
We really appreciate your patience and hope this helps.
I hope you are doing well today.
I'm following up with you to see if the information provide helps or if there is something else we can help you with.
