Server Memory Kit

This NEMIX RAM kit provides 64 GB of DDR5 registered ECC memory in four 16 GB modules. It is built for servers and workstations that require error correction and signal buffering for stable operation. The 288-pin RDIMM form factor fits compatible DDR5 server platforms. Buyers needing non-ECC or unbuffered DIMMs for desktop boards should look elsewhere.

Capacity and Speed

The four modules run at 4800 MT/s with a CAS latency of 40 at 1.10 V. The 64 GB total capacity handles multi-VM hosts, database buffers and large dataset workloads with headroom for simultaneous tasks. Workloads that exceed 64 GB or demand higher frequencies will require additional DIMM slots or faster-rated modules.

Build Integration

Each module uses a 1Rx8 organisation and registered signalling to reduce electrical load on the memory controller. The 288-pin DDR5 interface requires a motherboard with DDR5 RDIMM slots and ECC support. No heat spreader is fitted, leaving clearance for dense slot populations and standard server airflow.
