Capacity 128GB (8 x 16GB)

  • 128 GB total capacity from eight 16 GB modules
  • Registered ECC RDIMM protects data integrity in servers
  • Dual-rank 2Rx8 organisation increases memory density
  • DDR4 2400 MHz speed with CL17 latency
  • Standard 1.20 V operation reduces power draw

Server DDR4 ECC RDIMM kit

This 128GB kit contains eight 16GB registered DIMMs built for DDR4 servers and workstations that require ECC error correction. It is not compatible with desktop or laptop platforms.

Sustained load behaviour

The modules run at DDR4 2400 with CL17 latency and 1.20V, using dual-rank 2Rx8 organisation to maintain throughput during extended workloads. Major-brand chips and full QA testing support reliable operation under continuous demand.

Installation notes

Each module uses the standard 288-pin DDR4 DIMM form factor and seats in registered memory slots following the system manual's channel guidelines. Improper seating or mixing with unbuffered memory will prevent the system from posting.

Questions about this item

How much heat does the 1.20 V DDR4 2400 kit generate under continuous server load?

Each 16 GB module runs at the standard 1.20 V DDR4 voltage, so thermal output matches typical registered DIMM levels for this speed; ensure your chassis airflow follows the system vendor's guidelines.

What must my motherboard provide to run this 288-pin ECC RDIMM kit?

A DDR4 server or workstation board with registered DIMM slots, ECC support, and a qualified memory list that includes 2Rx8 modules at 2400 MHz.

Will these 2Rx8 registered sticks work alongside older 1Rx4 DDR4 RDIMMs in the same system?

Mixing ranks is platform-dependent; consult your server manual for supported rank-per-channel limits and population rules before combining 2Rx8 with other modules.
