The Lenovo 4X77A93556 is a 16GB 1Rx8 PC5-5600 ECC UDIMM-A — a DDR5 error-correcting memory module engineered for Lenovo ThinkSystem servers requiring validated, platform-matched RAM. The single-rank, 8-chip layout (1Rx8) delivers the full 16GB capacity from a single DIMM slot, which matters when slot count is constrained and you need to preserve expansion headroom. ECC (Error-Correcting Code) protection detects and corrects single-bit memory errors on the fly — a requirement in any server environment where data integrity and uptime take priority over raw throughput. Running at PC5-5600 (DDR5-5600), this module operates at the full rated speed of the DDR5 platform it pairs with, so you're not leaving memory bandwidth on the table with an underclocked module. Factory-new and sourced through the Lenovo supply chain, the 4X77A93556 is validated against Lenovo's hardware compatibility lists — not a generic JEDEC module that may or may not pass platform qualification.
Designed for Lenovo ThinkSystem servers and workstations that specify UDIMM-A DDR5 memory. Consult Lenovo's official Hardware Compatibility List (HCL) for your specific ThinkSystem model to confirm slot configuration, maximum capacity, and mixed-population rules before ordering. UDIMM-A is a Lenovo-specific connector variant — do not substitute a standard UDIMM or RDIMM in platforms that require UDIMM-A, as the keying and electrical signaling differ.
DDR5 UDIMM-A slots are keyed to prevent incorrect insertion, but always verify the slot population sequence in your server's maintenance manual before installing — most platforms require specific slot ordering for single- or dual-channel configurations. ECC must be enabled in BIOS/UEFI firmware; confirm it is active post-installation via system event logs or the platform management interface.
