    D54250WYK unstable in dual channel mode with DDR3 2133 (stable in single channel mode)


      I tried two different DDR3 2133 kits - G.Skill F3-2133C11D-16GRSL  and Corsair CMSX16GX3M2B2133C11.  With both the D54250WYK BIOS auto configures the memory to run at 2133.  However the system is not stable at all.  Windows will not boot and visual BIOS freezes randomly.  If I remove the bottom DIMM the system is stable in single channel mode at 2133.  In addition if I switch to manual memory configuration and run the memory at 1866 then the system is stable in dual channel mode as well.  This is happening with both kits from different manufacturers so it's definitively a BIOS issue.
