Server Memory Kit

This NEMIX RAM kit provides 128GB of DDR4 server memory across four 32GB modules. It is designed for systems that require registered ECC RDIMMs operating at 2933MHz. The modules are not compatible with standard desktop or PC computers.

Registered ECC Requirement

The single specification that decides fitment is the registered ECC RDIMM form factor with 2Rx8 organisation. Only motherboards and platforms explicitly supporting registered DDR4 ECC memory at this speed and rank configuration can use this kit.

Sustained Load Behaviour

Under sustained workloads the modules operate at the rated 1.2V with a CAS latency of 21. Registered buffering helps maintain signal integrity across all four slots during continuous operation in multi-socket server environments.

Questions about this item

What does 2933MHz mean once the memory is installed?

The modules run at 2933 MT/s, giving each 32GB DIMM a PC4-23400 data rate in a server that supports DDR4 2933.

What does the 288-pin DDR4 interface limit in practice?

The 288-pin DDR4 RDIMM form factor fits only DDR4 server slots that accept registered ECC modules.

What physical space does the 4 x 32GB kit need?

Four 288-pin RDIMM slots are required, one per module, in a system that supports 2Rx8 registered ECC memory.
