8GB DDR4-2133 ECC RDIMM

This 8GB DDR4 registered DIMM operates at 2133 MT/s with CL15 latency and 1.20V. It targets servers and workstations that require error-correcting memory for data integrity.

Registered buffer and ECC

The on-module register retimes clock, command and control signals to reduce electrical load on the memory controller. An 8-bit parity check enables single-bit error correction across the 1Rx4 organisation.

DDR4-2133 interface limit

The PC4-17000 standard caps transfer rate at 2133 MT/s, so bandwidth is fixed regardless of faster controller capability. Systems needing higher throughput must use modules rated for a faster DDR4 speed grade.

Questions about this item

Will the 8 GB DDR4-2133 CL15 registered ECC module need any maintenance or replacement during its service life?

The module is a solid-state component with no moving parts and no user-serviceable items; under normal server operation it does not require periodic maintenance or scheduled replacement.

What limit appears first when the 1Rx4 registered DIMM runs at DDR4-2133 continuously?

The registered buffer and on-die ECC logic set the electrical ceiling, so sustained throughput is bounded by the 2133 MT/s data rate and CL15 latency rather than thermal throttling.

How much heat and power does the 1.20 V registered ECC DIMM produce during all-day operation?

At the rated 1.20 V the module draws only a few watts, generating modest heat that standard server airflow handles without additional cooling.
