NEMIX RAM 128GB DDR4 2666 ECC LRDIMM Kit

This 128GB kit contains two 64GB DDR4 2666 LRDIMM modules rated PC4-21300 with CL19 latency. It is built for Dell EMC PowerEdge R7425 servers that require registered ECC memory. The load-reduced design helps maintain signal integrity when populating multiple slots. System administrators upgrading compatible Dell platforms will find the correct form factor and voltage here.

DDR4 2666 LRDIMM Practical Limits

DDR4 2666 sets the maximum data rate at 2666 MT/s and the kit runs at 1.2V. The 4Rx4 organisation increases density but requires a memory controller that supports quad-rank load-reduced modules. Mixing ranks or speeds can prevent the server from posting or force it to run at a lower rate. Buyers who need higher frequencies or different rank configurations must choose a different specification.

4Rx4 Load-Reduced Rank Decides Fit

The single specification that determines compatibility is the 4Rx4 load-reduced organisation. The Dell EMC PowerEdge R7425 memory controller must explicitly support quad-rank LRDIMMs for this kit to function. Servers limited to single or dual-rank registered DIMMs will not accept these modules. Verify the platform qualified-vendor list before purchasing.

Questions sur cet article

Should I choose the 128GB kit or a smaller capacity for my Dell EMC PowerEdge R7425?

This kit provides 128GB across two 64GB modules. Select it if your workload needs that total capacity and the server has two free 288-pin slots.

What does the 2666MHz rating deliver once installed in the R7425?

The modules run at DDR4 2666 (PC4-21300) with CL19 latency at 1.2V, giving the server its rated memory bandwidth for ECC LRDIMM workloads.

How does the LRDIMM interface affect maximum capacity on this platform?

Load Reduced DIMMs use a buffer to lower electrical load, letting the R7425 support higher-density 4Rx4 modules such as these 64GB sticks.
