The Lenovo 32GB TruDDR5 5600MHz (2Rx8) ECC UDIMM, part number 4X77A99752, is a server memory module. It is a single 32 GB DDR5 module in a 288-pin DIMM form factor, running at a memory clock speed of 5600 MHz in a dual-rank (2Rx8) configuration.
The module is an unbuffered type: a clocked unregistered DIMM (UDIMM) rather than a registered module. It supports ECC (error-correcting code), which detects and corrects memory errors during operation. This makes it suited to systems where data integrity matters.
As a server component, this memory is intended for adding to or upgrading the RAM in servers that use DDR5 ECC unbuffered DIMMs. It is used in business and data centre workloads where reliable, error-checked memory is needed.
