The Lenovo 4X77A88511 is a 16GB TruDDR5 memory module for servers, rated at 4800 MHz. It is a single-rank (1Rx8) unbuffered DIMM (UDIMM) in a 288-pin form factor, supplied as one 16 GB module. The product name lists it as suited to systems with machine types 7DF3, 7DCE and 7DCL.
The module uses DDR5 memory and is clocked and unregistered (unbuffered). ECC (error-correcting code) is supported, which helps detect and correct memory errors during operation.
Memory of this type is used to add or replace system RAM in servers that take unbuffered ECC DDR5 DIMMs. Typical uses include small business and departmental servers running file, application or virtualisation workloads, where error-correcting memory helps keep operation reliable.
