Capacity 256GB (2 x 128GB)

  • 256 GB total capacity with two 128 GB modules
  • DDR5 4800 MHz speed rated at PC5-38400
  • ECC registered RDIMM with EC8 error correction
  • Quad-rank 3DS TSV architecture for high density
  • 10 V standard DDR5 voltage for efficiency

Server DDR5 memory kit

This 256 GB dual-channel kit contains two 128 GB registered ECC RDIMMs built for DDR5 servers and workstations. Each module uses a 288-pin form factor and quad-rank 3DS/TSV organisation. The kit is not compatible with desktop or laptop platforms.

Capacity and headroom

The 256 GB total provides substantial headroom for virtualisation, large databases and memory-intensive compute workloads. Speed is rated at 4800 MHz with a CL40 latency at 1.1 V. Systems limited to lower memory speeds or fewer DIMM slots will not utilise the full capacity or bandwidth.

Registered ECC RDIMM requirement

This memory requires a platform that supports DDR5 registered ECC RDIMMs with 4Rx4 3DS/TSV ranking. Buyers whose servers or workstations only accept unbuffered or non-ECC modules cannot use this kit.

Questions sur cet article

Will the 288-pin DDR5 4800 RDIMM modules install in a server that currently runs DDR5 RDIMMs at a different speed?

The kit uses the standard 288-pin DDR5 RDIMM form factor and runs at 4800 MHz with CL40 latency at 1.1V; your server must support DDR5 Registered ECC memory and will typically negotiate the highest common speed across all populated slots.

How can I confirm the 256GB kit is operating correctly after installation?

Check the BIOS or UEFI memory information screen to verify that both 128GB modules are detected, showing 256GB total, DDR5 4800 MT/s, ECC Registered mode active, and the quad-rank 2S2Rx4 configuration reported.

What comes in the box and what must be purchased separately?

The package contains two 128GB DDR5 4800 EC8 RDIMM modules; no cables, brackets, or additional components are included, and no separate parts are required for installation beyond a compatible DDR5 server or workstation motherboard.
