128GB DDR3 1866 ECC LRDIMM quad-channel kit

This A-Tech kit supplies 128GB of DDR3 1866 memory in four 32GB modules. It uses ECC load-reduced DIMMs with a 4Rx4 organisation and runs at the standard 1.5V voltage. The quad-channel configuration targets multi-socket server and workstation platforms that accept DDR3 LRDIMMs.

Servers and workstations needing maximum DDR3

The 4Rx4 load-reduced design allows higher densities per channel than standard registered modules, suiting virtualisation hosts or database nodes that must populate every slot. Desktop or laptop systems cannot use these modules because they require DDR3 ECC LRDIMM support. Buyers who need non-ECC memory, unbuffered DIMMs, or a different DDR generation should look at other products.

4Rx4 load-reduced organisation

The quad-rank x4 layout reduces electrical loading on the memory bus, enabling the full 128GB capacity across four 240-pin DIMMs. This rank structure is the decisive factor for compatibility; the system memory controller and BIOS must explicitly support 4Rx4 LRDIMMs at DDR3 1866 speeds.

Questions about this item

Should I pick the 4x32GB kit or a different capacity for my server?

The kit provides 128GB total across four 32GB modules; choose it when your platform supports quad-channel DDR3 1866 and needs the full 128GB capacity.

What does the DDR3 1866 speed mean for actual server workloads?

At 1866 MHz with CL13 latency the modules deliver PC3-14900 bandwidth, reducing latency for database and virtualization tasks on compatible DDR3 platforms.

How does the LRDIMM 4Rx4 design affect memory scaling?

Load Reduced DIMM with quad-rank x4 organisation lowers electrical load on the memory bus, letting the server populate more slots at 1866 MHz without signal degradation.
