Server DDR4 ECC RDIMM

This 288-pin DDR4 registered DIMM delivers 8GB of ECC-protected memory at 2133 MT/s with CL15 latency. It operates at 1.20V and uses a 1Rx4 organisation, making it suitable for multi-socket server platforms that require registered modules with error correction. The module is validated for a wide range of Supermicro X10-series motherboards.

Registered buffer and ECC parity

On-board registers retime clock, command and control signals to reduce electrical load on the memory controller, allowing larger memory populations per channel. An 8-bit parity check provides single-bit error detection and correction, improving data integrity for workloads that cannot tolerate silent corruption. These features replace standard unbuffered non-ECC DIMMs in qualified server boards.

8GB capacity at DDR4 2133

The single 8GB rank fits entry-level virtualisation hosts, database nodes or compute clusters that run within the DDR4 2133 speed envelope. Systems needing higher bandwidth per core, larger per-module densities or faster memory clocks will require modules beyond this specification.

Questions sur cet article

Will the 1Rx4 ECC RDIMM module require any periodic maintenance or component replacement during its service life?

No, the DDR4 2133 module has no moving parts or user-serviceable components; once installed in a compatible 288-pin slot it operates without further maintenance.

What limit appears first when the registered DIMM runs continuously at its rated 2133 MT/s speed?

The primary sustained-use limit is thermal — the 1.20 V DRAM and register generate heat that must be dissipated by system airflow to maintain CL15 stability.

How much power does the 8 GB DDR4 2133 ECC RDIMM draw and how much heat does it produce during all-day operation?

At 1.20 V the module typically consumes a few watts, producing modest heat that standard server chassis airflow handles without additional cooling.
