NEMIX RAM
A 32 GB DDR5 ECC UDIMM running at 4800 MT/s with CL40 latency and 1.1 V operation
This NEMIX RAM module is a 32 GB DDR5 4800 ECC unbuffered UDIMM built with major OEM Samsung Micron Hynix chips. It operates at 1.1 V with CL40 latency and uses a 288 pin 2Rx8 layout. The part number ME38400-328K1 matches the Samsung M324R4GA3BB0-CQK reference for direct replacement.
It suits administrators upgrading Samsung branded servers workstations or NAS units that require DDR5 ECC unbuffered memory at this speed and voltage. Builders needing registered buffered RDIMM modules or non ECC consumer memory should look elsewhere because this stick is neither.
The single specification that decides fit is the DDR5 4800 PC5 38400 rating combined with ECC unbuffered UDIMM format. Only systems qualified for this exact data rate voltage and module type will accept it.

It will operate with other DDR5 ECC UDIMMs that match the 4800 speed, 1.10 V voltage and CL40 timing, but mixing ranks or speeds may force the system to run at the lowest common settings.
Check the memory speed, CAS latency and voltage in the BIOS or with a tool such as CPU-Z; they should read 4800 MT/s, CL40 and 1.10 V respectively.
The box contains one 32 GB 288-pin DDR5 ECC UDIMM; no additional components are required if your motherboard has a free DDR5 UDIMM slot.
