    Atom supports DDR3 w/ECC

    Quinn Community Member

      Can someone please help me to clarify if Atom E3825 supporting DDR3 with ECC?  When I used Intel Embedded Board Planner tool which shows E3825 is non-ECC but the comparison from this link shows all Atom supports DDR3 w/ ECC http://ark.intel.com/compare/78478,78477,78474,78476,85475.  Which one is correct?  The E3800 datasheet does not mention of ECC only being supported on certain processors.

          Hello Quinn

           

          This is from the E3800 Datasheet revision 3.6, section 12.1.1 ECC Support:

           

          The system memory controller supports ECC. When ECC is enabled, only Memory

          Channel 0 will be active. Memory Channel 1 will be disabled and used for the ECC data

          signals. Signals on Memory Channel 1 not used for ECC will be tri-stated.

           

          So ECC it is supported, the issue with the Board Planner should be reported.

           

          Thanks,

          Adolfo

              Hi AdolfoS,

              E3825 or lower only supports single channel memory per datasheet.  Is ECC still applied?  The pins are still there but datasheet doesn't mention about if ECC mux is still available.  I think both EBD and datasheet need to be updated.

               

              Thanks,
