Purpose-built server memory

This 64 GB DDR5 module is an ECC registered DIMM designed for Gigabyte H263-S62, H263-S63, H263-S64, MS03-6L0 and MS03-CE0 systems. It operates at 5600 MT/s with a CL46 latency and 1.1 V supply. The 2Rx4 organisation and 288-pin form factor match the qualified server platforms exactly.

Sustained-load behaviour

ECC correction and registered buffering keep data integrity intact during continuous multi-threaded workloads typical of workstations, NAS appliances and network switches. JEDEC-standard signalling at 5600 MT/s delivers consistent throughput without relying on short-term boost clocks. The single-rank-per-channel 2Rx4 layout maintains stable timing across all populated slots.

Deciding specification

Registered ECC with 2Rx4 organisation is mandatory for the listed Gigabyte servers; unbuffered or load-reduced DIMMs will not function in these platforms. Buyers needing standard desktop memory or non-ECC modules must choose a different product line.
