A-Tech 128GB DDR4 2666 ECC LRDIMM Kit

This A-Tech kit provides 128GB of DDR4 server memory across four 32GB modules. Each module is a 2Rx4 load-reduced DIMM with ECC error correction. The memory runs at 2666MHz with a CAS latency of 19 and operates at the standard 1.20V. It is built for quad-channel server and workstation platforms only.

For DDR4 servers and workstations that require

This memory suits administrators upgrading compatible DDR4 servers or workstations that specifically support load-reduced ECC DIMMs. It will not work in desktop or laptop computers. Buyers whose systems require standard registered DIMMs or unbuffered memory should look at something else.

288-pin DDR4 LRDIMM form factor with ECC

The modules use the 288-pin DDR4 LRDIMM form factor with ECC and a load-reduced buffer. Your server or workstation must support this exact combination of form factor, buffering and error correction for the kit to function. Verify the platform specifications before ordering.

Questions about this item

What comes in the 128GB kit and do I need anything else to install it?

The kit contains four 32GB DDR4 2666 ECC LRDIMM modules. No extra components are required for installation in a compatible server or workstation.

Should I choose this quad-channel 2Rx4 kit or a different capacity for my server?

This 128GB quad-channel kit uses four 2Rx4 modules at 1.2V. Select it when your platform supports DDR4 ECC LRDIMM and needs maximum capacity across four channels.

What does the 2666 MHz rating actually deliver once the modules are seated?

The modules run at DDR4 2666 (PC4-21300) with CL19 latency at 1.2V, providing ECC error correction and load-reduced buffering for stable server workloads.
