A-Tech 32GB DDR5 4800 ECC UDIMM 2Rx8 CL40 1.10V Server Memory

32GB DDR5 ECC UDIMM for servers

This 32GB DDR5 4800 module delivers ECC unbuffered memory for server and workstation systems that require error correction without registered buffering. It operates at the standard 1.10V DDR5 voltage with CL40 latency and a 2Rx8 rank configuration. The 288-pin DIMM is built as a direct replacement for the Micron MTC20C2085S1EC48BA1 part number.

Replaces Micron MTC20C2085S1EC48BA1

The module serves as a compatible equivalent when a system calls for that specific Micron part, allowing capacity expansion or failed-stick replacement without changing the memory architecture. The upgrade is worthwhile when the platform supports DDR5 4800 ECC UDIMM and the workload benefits from the additional 32GB of error-correcting capacity. It is not suited for platforms that require registered DIMMs or non-ECC consumer memory.

Simple DIMM installation with compatibility checks

Installation follows standard DDR5 DIMM seating in a 288-pin slot; the module is keyed to prevent incorrect orientation. The main risk is purchasing for a system that does not support DDR5 ECC unbuffered memory, which would render the stick unusable. Verifying the motherboard or server qualified-vendor list before purchase avoids the most common fitment issue.
