    D510MO BIOS issues


      Have D510MO with latest BIOS 10N 0542.

      This mobo previoulsy had a BIOS upgrade from 10J.

      Followed instructions to upgrade to 0400 to 10N and then to 0542.

      However, with 0542 unable to run 800MHz DIMM at manual setting 5-5-5-15 per Kingston datasheet (see attached).

      These are set of Kingston KHX6400D2K2/4G (2 x 2GB).

      There is a post on this being resolved with 10J 0303 D510MO BIOS Memory settings for PC2-6400


      Why has this functionality ceased? Is it available in 10J 0542 at all

      Are the DIMMs compatible?

      Do these require manual setting?


      Please advise.

          Hi JEWilson,


          Intel improved BIOS firmware since version 0400; it jumped from 10J to 10N. Memories at 800MHz require more voltage (1.85V) than 667MHz (1.8V). It is possible to use 1 memory stick at 800MHz, when you have 2 memories the board will fail. You might try to download the voltage. Kingston memory KHX6400D2K2/4G works at 667MHz (1.8V) and 800MHz(1.85V)


          Higher memory voltage increases processor temperature and it can damage the system.
