the processor, the speed settings in the BIOS and the operating voltage of the system. The loading
within a channel significantly affects memory speed.
Table 8 lists the memory configuration and performance details for the M420, based on the
population of the number and type of DIMMs per memory channel.

Green boxes are defaults for performance per watt.

White boxes (with lower voltage) can save power but will run at slower speeds.

White boxes (with higher voltage) can be custom configured in the BIOS.

Memory RAS features

RAS features help keep the system online and operational without significant impact to performance,
and can decrease data loss and crashing due to errors. RAS aids in rapid, accurate diagnosis of faults
which require service. Table 9 describes the memory RAS features supported on the M420.
