Dell EMC Unity: Unity DIMM report INCORRECT_SPEED in GUI (Dell EMC Correctable)

DDR 2400 DIMM supply is being replaced with DDR 2666 DIMMs, which are backward compatible.

Memory module (DIMM) reports INCORRECT SPEED in GUI

This reporting issue happens because the DDR 2400 DIMM supply is being replaced with DDR 2666 DIMMs which are backward compatible.
This is only a reporting issue, and these DDR 2666 DIMMs perform as expected and present no issues.

The hardware logs show no faults, but in some of the logs (TRiiAGE_ECOM.txt), you can see  ALRT_MEMORY_INCORRECT_SPEED  which may be shown in the GUI as well.

The warning/alerts can safely be ignored. It is OK to allow these higher speeds.

This reporting issue is resolved in Unity OE 5.0.

The part number in the KB is only an example. Other part numbers may be affected by the same issue.
