128GB DDR5 ECC UDIMM Kit

This NEMIX RAM kit delivers 128GB of DDR5 5200 ECC unbuffered memory across four 32GB modules. It runs at PC5-41600 speed with CL42 latency and 1.10V operation. The 2Rx8 organisation provides error correction for data integrity in servers and workstations.

Who this suits, who it does not

This kit suits administrators upgrading DDR5 platforms that accept 288-pin ECC UDIMMs and require 128GB capacity. Builders needing registered RDIMM modules, lower voltage than 1.10V, or speeds above 5200 should look at other options.

Deciding specification: 288-pin DDR5 ECC UDIMM

The 288-pin DDR5 ECC UDIMM form factor is the single specification that determines compatibility. Only motherboards designed for unbuffered DDR5 ECC memory can use these modules. Verify your platform supports this exact module type before purchase.

Questions about this item

Should I pick the 128GB kit or a smaller DDR5 5200 ECC UDIMM option?

The 128GB kit provides four 32GB modules for servers needing maximum capacity; choose a smaller kit only if your board has fewer slots or the workload fits in less memory.

What does the 5200 speed rating deliver in a live server?

DDR5 5200 (PC5-41600) runs at 5200 MT/s with CL42 latency at 1.1V, giving high bandwidth for virtualization and database workloads on compatible platforms.

How does the 288-pin DDR5 ECC UDIMM interface limit what I can install?

The 288-pin DDR5 ECC UDIMM form factor fits only DDR5 UDIMM slots with ECC support; it will not seat in RDIMM, LRDIMM or previous-generation sockets.
