The Lenovo 16GB TruDDR5 5600MHz (1Rx8) ECC UDIMM, part number 4X77A99751, is a single 16 GB DDR5 memory module in a 288-pin DIMM form factor. It runs at a memory clock speed of 5600 MHz and uses a single-rank x8 (1Rx8) configuration.
This is an unbuffered (clocked unregistered) module with ECC (error-correcting code) support. ECC detects and corrects memory errors, which helps maintain data integrity in systems that run continuously or handle important workloads.
The module is listed as a component for PC and server use. It is suited to Lenovo systems that take ECC UDIMM DDR5 memory, such as entry-level servers and workstations where error-correcting memory is required. It can be used to expand memory capacity or to replace an existing module.
