A 256 GB dual-channel kit of 128 GB DDR4 3200 ECC LRDIMM modules for server and workstation memory upgrades
Capacity 256GB (2 x 128GB)
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.
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.
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.

Other versions of this model
Same family, different memory, cooler or clock — compare before you commit.
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.
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.
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.
