Server Memory Kit

This NEMIX RAM kit provides 256GB of DDR5 ECC unbuffered UDIMM memory across eight 32GB modules. It is built for servers and workstations that require error-correcting code to maintain data integrity under heavy workloads. The kit suits IT professionals upgrading compatible enterprise platforms.

DDR5 4800 CL40 Specification

The modules run at DDR5 4800 (PC5-38400) with a CAS latency of CL40 and operate at 1.10V. Each stick is a 2Rx8 dual-rank device using major OEM chips from Samsung, Micron or Hynix. This speed and latency combination determines whether the kit matches your platform's qualified vendor list.

Build Integration

The 288-pin UDIMM form factor fits standard DDR5 unbuffered DIMM slots on supporting server and workstation motherboards. No heat spreaders are included, so airflow across the modules must be provided by the chassis. ECC function requires a platform that enables error correction on unbuffered memory.

Questions about this item

Will the 4800 MT/s speed run at that rate in my server?

The modules are rated for DDR5 4800 (PC5 38400); actual operating speed depends on the motherboard and CPU memory controller, which may run them at a lower JEDEC speed.

What does the ECC unbuffered design mean for my platform?

These are 288-pin DDR5 ECC UDIMMs with 2Rx8 organisation; they provide error correction without a register, so they require a motherboard that supports unbuffered ECC DDR5.

Do the 32 GB sticks need a heatsink or special slot spacing?

The kit uses bare 288-pin DDR5 UDIMMs with no heat spreader; they fit standard DDR5 DIMM slots and do not require extra clearance beyond normal module height.
