Question I have X10DRW-NT with 16pcs of DDR4-2133 RDIMM and using 2xE5-2690 v3 CPUs. Currently BIOS is reporting the memory frequency only to be 1866, what happened? Please advise. Answer Please modify following BIOS settings, then you should be able to get memory frequency back to 2133: § Advanced >> Chipset Configuration >> North Bridge >> Memory Configuration >> Enforce POR -> Disabled (default Enabled) § Advanced >> Chipset Configuration >> North Bridge >> Memory Configuration >> Frequency >> 2133 (default Auto) Soft remind, there is no guarantee for this function, since it's not follow Intel POR.
