Capacity 256GB (2 x 128GB)

  • 256 GB total capacity from two 128 GB modules for large server workloads
  • DDR4 3200 speed at CL22 latency accelerates data-intensive applications
  • ECC Load Reduced DIMM technology corrects errors and reduces electrical load on the memory bus
  • Quad-rank 4Rx4 organisation maximises density per 288-pin slot
  • 20 V standard DDR4 voltage keeps power draw predictable

High-capacity DDR4 ECC LRDIMM kit

This A-Tech kit delivers 256GB across two 128GB DDR4 3200 modules built for servers and workstations that require load-reduced ECC memory. The quad-rank 4Rx4 organisation and 1.20V operation suit platforms designed for maximum density per channel.

Straightforward DIMM installation

The 288-pin modules seat in standard DDR4 DIMM slots following the motherboard's channel population rules. The most common issue is attempting to use these LRDIMMs in desktop or laptop boards that only accept unbuffered memory, which will prevent the system from posting.

Verify platform support for LRDIMM

Confirm that your server or workstation explicitly lists DDR4 load-reduced ECC DIMMs in its qualified vendor list and that the memory controller supports 4Rx4 modules at the intended speed. Mixing ranks or exceeding the maximum supported capacity per channel will cause instability.

Questions about this item

How can I confirm the 3200 MHz DDR4 kit is running at its rated speed after installation?

Enter the server BIOS or UEFI and verify the memory frequency shows 3200 MHz with CL22 timings at 1.20 V; the modules are 288-pin DDR4 ECC LRDIMM 4Rx4, so the firmware will report the correct data rate if seated properly.

What comes in the 256 GB package and what must be sourced separately?

The box contains two 128 GB DDR4 3200 ECC LRDIMM modules (part number NE-SS-0717); no heat spreaders, cables, tools or additional DIMMs are included — only the memory sticks themselves.

Which version of this A-Tech DDR4 server memory should I choose for a dual-channel 256 GB upgrade?

Select the 256 GB (2 x 128 GB) 4Rx4 PC4-25600L kit; it provides the full 256 GB capacity in a matched dual-channel pair of quad-rank LRDIMMs designed for compatible DDR4 servers and workstations.
