Targeted ECC RDIMM upgrade

This 64GB DDR5 5600 CL46 registered module is built for Gigabyte R163-S30, R163-S32, R163-S35, R163-SG0 and R163-SG2 servers and workstations. It delivers error-correcting, buffered memory for workloads that require data integrity and sustained uptime.

JEDEC-standard build and pinout

The 288-pin RDIMM operates at 1.1V with a 2Rx4 organisation and no heat spreader, matching OEM specifications for direct installation in the listed Gigabyte platforms. JEDEC and RoHS compliance ensures a warranty-safe upgrade path.

Registered ECC requirement

This module only works in systems that support DDR5 registered ECC memory; it will not function in standard desktop boards or alongside unbuffered or load-reduced DIMMs. Verify your platform accepts registered ECC before purchasing.
