Debian : MPI code - Intel compiler - [Hardware Error]: Unified Memory Controller Error: DRAM ECC error

When running an executable compiled with intel mpiicc, I get, after 30 minutes of running, the following errors : kernel:[29585.573874] [Hardware Error]: Corrected error, no action required.

are incompatibilies between my motherboard, CPU model or bad version of Intel compiler SDK ? These errors appears roughly every 5 minutes during the execution. I am using the intel compilers version compilers_and_libraries_2020.1.217. **I have also the same error messages when I compile with MPI from official Open-MPI Debian 10 repository version.** I should modify maybe an option in the BIOS but I am not sure. If someone had an idea to solve this issue, this would be fine to tell it.
