Capacity 128GB (8 x 16GB)

  • 128 GB total capacity with eight 16 GB modules for high-density server workloads
  • DDR5 5600 speed rated at PC5-44800 for fast data throughput
  • ECC registered design detects and corrects memory errors to protect data integrity

  • Standard 1.1 V DDR5 voltage reduces power draw while maintaining stability

Server memory kit for DDR5 workstations

This 128GB kit contains eight 16GB registered DIMMs built for DDR5 servers and workstations. It is not compatible with desktop or laptop computers. The modules add ECC protection and registered buffering for data integrity under heavy workloads.

288-pin RDIMM form factor with registered design

Each module uses the standard 288-pin DDR5 DIMM layout and includes an on-board register that reduces electrical load on the memory controller. The registered design supports stable operation in multi-channel server boards. Single-rank 1Rx8 organisation helps maintain signal quality at rated speed.

DDR5 5600 speed with CL46 latency

Rated at 5600 MT/s (PC5-44800) with a CAS latency of 46 cycles at 1.1V. This speed grade determines whether the kit matches your platform's qualified memory list. Buyers who need a different data rate or lower latency should verify their system specifications before ordering.
