Memory Ras Features; Memory Speed Capabilities - Dell PowerEdge T320 Technical Manual

maximum speed supported by the processor, the speed settings in the BIOS, and the operating
voltage of the system.
Table 10 lists memory configuration and performance details for the T320 based on the population
of the number and type of DIMMs per memory channel.

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 11 describes the RAS features supported on the T320.

Description
Increased memory reliability can be a result from this selectable platform profile
that adjusts parameters to reduce faults regarding refresh rates, speed,
temperature and voltage
Demand scrubbing is the ability to write corrected data back to the memory once
a correctable error is detected on a read transaction.
Patrol scrubbing proactively searches the system memory, repairing correctable
errors.
Recovery from Single DRAM Device Failure (SDDC) provides error checking and
correction that protects against any single memory chip failure as well as multi-bit
errors from any portion of a single memory chip.
