  • Quad-channel kit optimises memory bandwidth
  • 2 V standard voltage reduces power draw

128GB quad-channel ECC RDIMM kit

This 128GB kit contains four 32GB DDR4 2133 modules built for registered ECC server and workstation platforms. The dual-rank x4 organisation and CL15 latency suit multi-threaded workloads that demand data integrity. It is not compatible with desktop or laptop computers.

Registered 288-pin DIMMs at 1.2V

Each module uses major-brand chips on a 288-pin registered DIMM running at the standard 1.20V. The registered buffer reduces electrical load on the memory controller, allowing full population of all four slots in supported quad-channel systems. Verify your platform's qualified-vendor list before installation.

Replaces non-ECC or lower-capacity DDR4 RDIMMs

The jump is worthwhile when your workload outgrows unbuffered memory or when single-rank modules limit total system capacity. If your board only accepts unregistered DIMMs or caps speed below 2133, this kit will not function.
