A-Tech 256GB (4x64GB) DDR4 2400 ECC LRDIMM 4Rx4 Server RAM

SKU CH-741Q-GBX2R

A 256 GB quad-channel kit of four 64 GB DDR4 2400 ECC LRDIMM modules with CL17 latency and 1.2 V operation

  • Capacity256GB (4 x 64GB)
  • SpeedDDR4 2400 (PC4 19200)
  • CAS LatencyCL17
  • Voltage1.20V
  • ECCYes
  • Buffered/RegisteredLoad Reduced

Capacity 256GB (4 x 64GB)

  • 256 GB total capacity across four 64 GB modules for heavy server workloads
  • DDR4 2400 MHz speed with CL17 latency delivers fast data access
  • ECC Load Reduced DIMM technology corrects errors while reducing electrical load on the memory bus
  • 288-pin DIMM form factor fits DDR4 server and workstation slots only
  • 2 V standard DDR4 voltage keeps power draw low for dense configurations

Server-grade capacity and rank

This 256 GB kit comprises four 64 GB DDR4 2400 ECC LRDIMM modules built for servers and workstations that support load-reduced memory. The quad-rank 4Rx4 organisation lets each module present a single electrical load to the memory controller, allowing higher total capacity per channel than standard registered DIMMs. It is not compatible with desktop or laptop platforms.

Headroom for virtualisation and large datasets

The 256 GB total provides ample space for running multiple virtual machines, large in-memory databases or heavy rendering jobs without swapping. At DDR4 2400 CL17 the bandwidth suits typical dual-socket server workloads, while the 1.2 V operation keeps power draw within standard DDR4 limits. Systems limited to lower memory speeds or fewer populated slots will not reach the full kit capacity.

Load-reduced design and 288-pin DIMM form factor

LRDIMM buffering reduces electrical loading on the motherboard, improving signal integrity when all slots are filled. The 288-pin DIMM layout fits standard DDR4 server sockets and the quad-channel kit labelling guides correct population order. Major-brand DRAM chips and per-module testing aim to deliver consistent reliability in 24/7 environments.

Questions sur cet article

Will these 4Rx4 LRDIMM modules run with my existing DDR4 2400 RDIMMs?

No — Load Reduced DIMMs must not be mixed with standard Registered DIMMs; the memory controller will not train both types together.

How do I confirm the kit is running at 2400 MT/s with CL17 after installation?

Check the BIOS memory information screen or run a tool such as dmidecode; it should report 2400 MT/s, 1.20 V and CAS latency 17 for each 64 GB module.

Does the 256 GB kit include only the four 288-pin modules or any extra parts?

The box contains exactly four 64 GB DDR4 2400 ECC LRDIMM modules; no cables, brackets or additional hardware are supplied.
