Capacity and purpose

This is a 128GB kit built from four 32GB DDR5 4800 registered ECC modules. It targets servers and workstations that require error correction and signal buffering for stable operation under continuous load.

Platform fit

The modules use the 288-pin RDIMM form factor and run at the standard 1.10V. They install in quad-channel configurations on boards wired for DDR5 registered memory and are not compatible with desktop or laptop platforms.

Sustained behaviour

Registered signalling and on-die ECC maintain data integrity during long-running workloads. The CL40 timing and 4800 MT/s rate deliver steady throughput without the voltage overhead that can accumulate heat in extended sessions.

Highlights
