Capacity 256GB (8 x 32GB)

  • 256 GB total capacity from eight 32 GB modules
  • DDR4 2666 MHz speed rated at PC4-21300
  • ECC registered design protects data integrity in servers
  • Dual-rank 2Rx4 organisation increases memory density per channel
  • Standard 1.2 V DDR4 voltage keeps power draw low

Server DDR4 ECC RDIMM kit

This 256GB kit contains eight 32GB registered DIMMs built for DDR4 servers and workstations. Each module runs at 2666MHz with CL19 latency and 1.20V operation. ECC and registered buffering protect data integrity in multi-socket platforms.

Capacity and headroom

The 256GB total (8x32GB) supports large virtualisation clusters, in-memory databases and heavy rendering workloads. Dual-rank 2Rx4 organisation fills eight DIMM slots, so further expansion requires higher-density modules or additional memory channels.

Registered ECC requirement

This memory only works in systems that accept DDR4 RDIMMs with ECC. Desktop and laptop boards that use unbuffered non-ECC DIMMs cannot use these modules. Verify your platform supports registered ECC DDR4 before purchase.

Questions about this item

Will these 2666 MHz CL19 2Rx4 registered modules work in the same channel as my existing DDR4 2666 ECC RDIMMs?

Mixing modules of the same speed, voltage, rank and registered type is generally supported, but the server's memory controller and BIOS determine final compatibility; consult the system manual for approved population rules.

How can I confirm the kit is running at 2666 MHz with ECC active after installation?

Check the POST memory summary or BIOS memory configuration screen for 2666 MT/s, CL19 timings, 1.2 V and ECC enabled on all 256 GB.

Does the 8-module kit include any heatsinks, cables or installation tools, or must I buy them separately?

The package contains only the eight 32 GB 288-pin DDR4 2666 CL19 1.2 V ECC registered DIMMs; no heatsinks, cables or tools are supplied.
