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.

Otázky k tomuto produktu

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.
