128GB DDR5-4800 ECC Registered RDIMM

This 128GB DDR5-4800 module is an ECC Registered RDIMM built for server platforms that require registered memory with error correction. It runs at PC5-38400 speed and uses a 4Rx4 organisation. The part is equivalent to Lenovo part number 4X77A77034 and is supplied as a 100% compatible third-party module from major-brand chipsets.

Who this suits and who should look elsewhere

This module suits administrators upgrading or repairing Lenovo servers that specify a 128GB DDR5-4800 4Rx4 ECC Registered RDIMM. It is not for systems that require unbuffered UDIMMs, non-ECC memory, lower capacities, different speeds, or a different rank configuration. Buyers needing consumer desktop memory or laptop SO-DIMMs should look at other product lines.

The specification that decides fit

The single specification that decides whether this is the right part is the 4Rx4 Registered ECC DDR5-4800 organisation; the server memory slot and BIOS must support this exact rank width and registered buffer type for the module to function.

Questions about this item

Will the 128GB DDR5-4800 RDIMM need replacement due to wear or degradation over time?

The module uses a major brand chipset and is covered by a lifetime warranty, so no scheduled replacement is expected under normal server operation.

What limits sustained throughput on the 4Rx4 DDR5-4800 registered module?

The PC5-38400 data rate of 4800 MT/s is the primary ceiling; the 4Rx4 organisation lets the memory controller interleave ranks to keep bandwidth near that peak.

How much heat and power does the 128GB DDR5 RDIMM produce during all-day server loads?

Registered DDR5 modules run at the standard 1.1 V; the 4Rx4 density spreads activity across ranks, keeping thermals within typical server DIMM limits.
