Kit Configuration

This NEMIX RAM kit provides 128GB total capacity across four 32GB DDR5 5200MHz ECC UDIMM modules. It is built for servers and workstations that require error-correcting memory with unbuffered operation. The dual-rank 2Rx8 organisation and 1.1V voltage match standard DDR5 specifications for compatible platforms.

Suitable Use Cases

This kit suits administrators upgrading DDR5-capable servers or workstations that accept 288-pin ECC UDIMMs at 5200MHz with CL44 latency. It is not for systems limited to registered DIMMs, platforms restricted to lower DDR5 speeds, or builds needing non-ECC memory. Buyers whose motherboards require RDIMMs or different voltage should look elsewhere.

Deciding Specification

The unbuffered ECC UDIMM format is the single specification that decides fitment because only boards designed for 288-pin unbuffered ECC DDR5 can use this kit. Registered or non-ECC slots will reject these modules, making this attribute the definitive compatibility gate before purchase.

Questions about this item

How do I install the four 288‑pin DDR5 UDIMMs in the correct slots?

Insert each 32 GB module into the motherboard's DDR5 UDIMM slots following the board's population guide; the key notch on the 288‑pin edge connector prevents backward insertion, which is the step most often missed.

What maintenance or replacement will this ECC UDIMM kit need over time?

No periodic maintenance is required; if a module fails, the lifetime replacement warranty covers a direct swap of the defective 32 GB stick.

What limit appears first when the kit runs at 5200 MHz under sustained load?

The CAS latency of 44 cycles at 1.1 V sets the timing boundary before thermal or voltage headroom becomes the bottleneck.
