32 GB DDR5 ECC RDIMM Server Module

This 32 GB DDR5-4800 ECC registered DIMM is built for servers and workstations that require error-correcting memory. It operates at 1.10 V with a CAS latency of 40 and uses a 1Rx4 rank configuration. The module is a direct replacement for several Hynix part numbers used in enterprise platforms.

Compatibility check for DDR5 RDIMM slots

Verify that your motherboard supports DDR5 registered ECC memory and provides 288-pin RDIMM slots. The system must accept 1.10 V modules and a 1Rx4 organisation. Consult the hardware manual for approved memory population rules and maximum capacity per channel before ordering.

No accessories or software included

The package contains only the memory module itself. There are no heat spreaders, cables, configuration utilities or driver discs supplied. Installation relies entirely on the platform firmware to initialise the module at the rated 4800 MT/s speed and ECC functionality.
