128GB DDR4 2133 ECC LRDIMM Kit

This 128GB kit contains four 32GB DDR4 2133 ECC Load Reduced DIMMs. Each module is a 288-pin 4Rx4 quad-rank unit operating at 1.20V with CL15 latency. The kit is built for servers and workstations that require registered ECC memory.

Suited for DDR4 servers needing 4Rx4 LRDIMMs

This memory fits platforms that specifically support DDR4 ECC Load Reduced DIMMs in a quad-rank x4 organisation. It will not work in desktop or laptop computers. Builders whose systems accept only standard registered DIMMs or non-ECC modules should look elsewhere.

Quad-rank 4Rx4 organisation decides compatibility

The 4Rx4 rank structure is the critical specification; the motherboard and CPU memory controller must explicitly support 4Rx4 Load Reduced DIMMs. If the platform qualifies only for single-rank, dual-rank or standard registered modules, this kit will not function.

Questions sur cet article

How do I install these 288-pin DDR4 LRDIMMs in a quad-channel server, and which step is most often missed?

Power down, open the chassis, align each module's notch with the slot key, press firmly until both retention clips click, then populate all four channels per the motherboard manual to activate quad-channel mode.

What maintenance or replacement will this 128GB 4Rx4 ECC kit need over its service life?

No scheduled maintenance is required; ECC corrects single-bit errors on the fly, and modules are replaced only if the system logs uncorrectable errors or a DIMM fails POST.

What limit appears first when these 1.20V CL15 modules run sustained workloads?

The 2133 MT/s data rate and four-rank electrical loading per channel set the throughput ceiling before voltage or thermal limits are reached.
