128GB DDR5 RDIMM for servers

This module delivers 128GB of registered ECC DDR5 memory in a single 288-pin stick. It targets administrators upgrading Hynix-compatible servers or workstations that require registered modules for stability under sustained loads.

Capacity headroom and limits

The 128GB density suits virtualization hosts, database nodes and memory-hungry analytics workloads. Four-rank 4Rx4 organisation maximises capacity per slot but increases electrical loading, so total usable capacity depends on the motherboard's qualified-vendor list and maximum rank-per-channel limits.

Registered ECC at 4800 MT/s

Registered buffering and on-die ECC protect data integrity in mission-critical deployments while the JEDEC-standard 4800 MT/s rate ensures broad platform compatibility. Systems needing higher frequencies or unbuffered DIMMs must select a different module type.

Questions about this item

Will this 128GB DDR5 4800 CL40 4Rx4 RDIMM run alongside my existing DDR5 4800 ECC registered modules?

Yes, it matches DDR5 4800 (PC5-38400), 1.1V, CL40, 4Rx4 registered ECC specs, so it will operate at the same speed and timing when populated in compatible slots.

How can I verify the module is detected and running at 4800 MT/s with ECC active after installation?

Check the system BIOS or UEFI memory information screen; it should show 128GB per module, 4800 MT/s data rate, CL40 latency, 1.1V voltage and ECC enabled.

Does the package include only the 288-pin RDIMM or are any cables or brackets supplied?

The box contains one 128GB 288-pin DDR5 RDIMM; no cables, brackets or additional accessories are included.
