32GB DDR5 ECC RDIMM for Server Upgrade

This 32GB DDR5-4800 ECC registered DIMM is built for server and workstation platforms that require error-correcting registered memory. It replaces the Samsung M321R4GA0BB0-CQK module and delivers 4800MHz speed with CL40 latency at 1.10V. Buyers expanding memory capacity in compatible enterprise systems will find this single-rank 1Rx4 module suitable for qualified configurations.

Verify Platform Support Before Ordering

Confirm that your motherboard and processor support DDR5 ECC registered DIMMs at 4800MHz and accept 1Rx4 organisation. The module uses the 288-pin DIMM form factor and operates at the standard 1.1V DDR5 voltage. Systems limited to unbuffered non-ECC memory or older DDR generations cannot use this module, so check the vendor memory-qualified list before purchase.

Registered Design With Samsung Chipset

The registered buffer reduces electrical load on the memory controller, aiding stability in multi-DIMM server configurations. Samsung chipset components are used throughout, and each unit undergoes quality-assurance testing for dependable operation. The 288-pin edge connector matches the DDR5 DIMM standard, ensuring a secure seat in compatible server and workstation slots.
