RAS aids in rapid, accurate diagnosis of faultsthat require service. Table 10 describes the RAS features supported on the R320.Table 10. Memory RAS featuresFeature DescriptionDense configurationoptimized profileIncreased memory reliability can be a result from this selectable platform profilethat adjusts parameters to reduce faults regarding refresh rates, speed,temperature and voltage.Memory demand andpatrol scrubbingDemand scrubbing is the ability to write corrected data back to the memory oncea correctable error is detected on a read transaction.Patrol scrubbing proactively searches the system memory, repairing correctableerrors.
