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.

Highlights

  • 128 GB capacity scales server workloads

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.
