32GB DDR5-4800 ECC RDIMM

This 32GB DDR5-4800 registered DIMM adds ECC-protected capacity to compatible Lenovo servers. It operates at PC5-38400 speed with a 1Rx4 organisation for stable operation in multi-module configurations. The module is built for environments that require error correction and registered signalling.

Suited for Lenovo-qualified platforms needing 32GB

Buyers who need non-ECC unbuffered memory for consumer desktops or laptops cannot use this registered ECC design. Systems that require a different rank structure, voltage, or form factor should look at other memory types.

DDR5-4800 registered ECC with 1Rx4 layout

The DDR5-4800 registered ECC specification and 1Rx4 rank configuration determine whether this module matches the server memory slots and population rules. Verify the platform memory guide for supported speeds, ranks, and maximum capacity per channel before purchase.

Questions about this item

How do I install the 4X77A81438 RDIMM in a Lenovo server and what step is often missed?

Power down the server, open the chassis, locate the DDR5 DIMM slots, align the notch on the 1Rx4 module with the slot key, press firmly until both ejector clips click shut, then verify in BIOS that all 32GB is recognised at 4800 MT/s.

What maintenance or replacement will the 32GB DDR5-4800 ECC module need over its service life?

No scheduled maintenance is required; the module carries a lifetime warranty, so replacement only occurs if a memory error is logged or a capacity upgrade is desired.

What limit appears first when the 1Rx4 RDIMM runs sustained workloads at 4800 MT/s?

The JEDEC-rated 4800 MT/s data rate is the ceiling; sustained loads cannot exceed this speed without overclocking, which the registered ECC design does not support.
