Table 9 illustrates the maximum achievable speed of the Intel Xeon processor E5-2400 v2 product

family based on memory loads.

 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

that require service. Table 10 describes the RAS features supported on the R320.

Feature

Description

Dense configuration

optimized profile

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.

Memory demand and

patrol scrubbing

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.
