The R420 supports memory speeds of 1600 MT/s, 1333 MT/s, 1066 MT/s, and 800 MT/s depending

on the DIMM types installed and the configuration. All memory on all processors and channels run

at the same speed and voltage. By default, the systems run at the highest speed for the channel with

the lowest DIMM voltage and speed. The operating speed of the memory is also determined by the

maximum speed supported by the processor, the speed settings in the BIOS, and the operating

voltage of the system.

Table 9 lists memory configuration and performance details for the R420 based on the population

of the number and type of DIMMs per memory channel.

Reliability, availability, serviceability (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 that require service. Table 10 describes the RAS

features supported on the R420.
