32 GB DDR5 ECC RDIMM for servers

This module provides 32 GB of DDR5 error-correcting registered memory for compatible workstations, NAS units, network switches and servers. It operates at 5200 MT/s with a CL42 latency and a 1.1 V supply. The 2Rx8 organisation and 288-pin form factor match JEDEC-standard slots designed for registered DIMMs. It is not compatible with standard desktop computers or unbuffered memory configurations.

Sustained operation with error correction

Registered buffering reduces electrical load on the memory controller, allowing stable operation in multi-DIMM server configurations over long periods. On-die ECC detects and corrects single-bit errors in real time, protecting data integrity during continuous workloads. The 1.1 V DDR5 voltage helps limit heat rise without a heat spreader, supporting consistent throughput in densely populated chassis.

CL42 latency at 5200 MT/s

The CAS latency of CL42 at the rated 5200 MT/s speed determines how quickly the module responds to read commands. This timing is the key figure for matching existing memory populations or meeting platform timing requirements. Buyers who need lower latency or different rank organisation should verify their system specifications before purchasing.
