16GB DDR5-4800 ECC UDIMM

This 16GB DDR5-4800 ECC UDIMM provides registered error-correcting memory for Lenovo-compatible servers and workstations. It suits administrators who need validated replacement modules for supported platforms. The single-rank 1Rx8 organisation keeps the electrical load low on populated channels. Buyers who require higher-capacity DIMMs or non-ECC memory for consumer boards should look elsewhere.

100% Lenovo-compatible replacement

The module is built to match Lenovo part number 4X71K53893 and carries a lifetime warranty from the third-party supplier. That equivalence means the firmware and timings are tested against the vendor qualification list. No extra software or configuration utilities are bundled with the stick itself. The warranty covers the hardware only and does not extend to system-level support.

Simple DIMM installation

Installation follows the standard UDIMM slot procedure: align the key notch, press until the latches click, and verify population order in the system manual. The most common issue is mixing ranks or speeds across channels, which can prevent the server from posting. Another frequent error is inserting the module into a board that does not support DDR5 ECC UDIMMs.

Questions about this item

Will the ECC UDIMM need any firmware updates or periodic reseating during its service life?

The module is a standard 1Rx8 DDR5-4800 ECC UDIMM with no firmware; reseating is only required if the system is moved or the slot oxidises.

What limits sustained write throughput on this 16 GB DDR5-4800 stick?

The PC5-38400 data rate of 4800 MT/s and the single-rank 1Rx8 organisation set the maximum sustained bandwidth.

How much extra heat or fan noise does the 16 GB DDR5-4800 add when the server runs all day?

A single 16 GB DDR5-4800 ECC UDIMM typically draws only a few watts, so the thermal load and acoustic impact are negligible in a ventilated chassis.
