■ The B440 M2 server needs at least one DIMM pair installed for each CPU.
■ DIMMs sold as kits are matched pairs and must remain together when installed in a particular
pair of same-colored (blue, white, yellow, or black) pairs of slots.
■ The DIMMs installed in slots for an absent CPU are not recognized.
■ Memory DIMMs should be installed evenly across the installed CPUs, though it is not a
requirement.
■ Mixing DIMM speeds will cause the faster DIMMs to run at the speed of the slower DIMMs.
■ Your selected CPU(s) can have some affect on performance. The CPUs must be of the same
type.
