Server Memory Upgrade
This 128GB DDR5 4800 ECC Registered RDIMM is built for workstations and servers that require error-correcting registered memory. It operates at 1.1V with CL40 latency and a 4Rx4 rank configuration across 288 pins. The module replaces Hynix parts HMCT04MEERA129N, HMCT04MEERA131N, HMCT04MEERA133N and HMCT04MEERA135N.
DDR5 4800 Interface Limits
The DDR5 4800 standard provides a PC5-38400 data rate that cannot be exceeded without platform support for higher JEDEC speeds. Registered DIMMs add a clock cycle of buffering that desktop consumer boards do not expect. Mixing this module with unbuffered or load-reduced ECC memory is not supported by the memory controller.
Replacing Older Registered DIMMs
This module upgrades systems currently running lower-capacity or slower registered ECC DDR5 DIMMs where the platform qualifies 128GB 4Rx4 parts at 4800 MT/s. The jump is worth it when the workload demands maximum registered memory density per slot and the server or workstation vendor lists these Hynix part numbers as compatible.

Otázky k tomuto produktu
How do I know if this 128GB DDR5 4800 CL40 4Rx4 RDIMM is the right capacity and rank for my server?
Choose this 128GB 4Rx4 module when your platform requires a single high-density registered DIMM at DDR5 4800 with CL40 latency and 1.1V operation.
What does the DDR5 4800 PC5-38400 rating deliver once the module is installed in a compatible server?
The module runs at 4800 MT/s, providing a peak bandwidth of 38400 MB/s per DIMM with CL40 timing and ECC error correction active.
How does the 288-pin DDR5 registered ECC interface limit real-world use in my system?
The 288-pin RDIMM form factor fits only DDR5 server and workstation boards that support registered ECC memory; it cannot be used in unbuffered or consumer platforms.
