SK hynix 128GB DDR5-4800 ECC Registered Memory (RDIMM) (HMCT04AEERA131N) – 4Rx4, PC5-38400

The SK hynix 128GB DDR5-4800 ECC registered module is designed for servers and data-centre systems that need error-correcting memory. Its ECC design and registered buffer help keep data accurate under continuous load. Speed is rated at 4800 MT/s. Installation takes only a few minutes.

Error-correcting memory for critical workloads.

Error-Correcting Memory for Business-Critical Systems

Servers running databases, virtual machines and file services need memory that can run around the clock; a single uncorrected memory error can crash an application or corrupt data.

This 128GB DDR5-4800 RDIMM uses ECC to detect and correct single-bit errors, and its registered design reduces the electrical load on the memory controller so servers can run more modules reliably.

Specifications That Match Your System

Error Correction and Stability

ECC memory corrects single-bit errors automatically, which helps prevent crashes and silent data corruption in systems that run around the clock.

Setup Instructions

How to Install the Memory

1. Power down the system, unplug all power cords and use an anti-static wrist strap.
2. Check the system’s memory population guide for the correct slots and channel order.
3. Insert each module, aligning the notch, until both retention clips lock.
4. Power on and confirm the memory is detected in the BIOS or system management interface.
