Lenovo ThinkSystem ECC UDIMM

This 16GB DDR4 3200 module is built for Intel-based Lenovo ThinkSystem servers and workstations. It carries ECC error correction and runs at 1.2V without a heat spreader. The single 2Rx8 rank fits standard 288-pin UDIMM slots. It matches Lenovo part 4X77A77495 for direct replacement.

Suited for compatible Lenovo platforms only

Administrators expanding memory in supported ThinkSystem servers will find this module validated for that environment. Builders using non-Lenovo motherboards, consumer desktops, or laptops should look elsewhere because the firmware and timing are tuned for specific Lenovo Intel platforms. Systems requiring registered or load-reduced DIMMs cannot use this unbuffered design.

ECC unbuffered DDR4 3200 with CL22

The decisive specification is the combination of ECC, unbuffered signalling, and CL22 latency at 3200 MT/s. That trio determines whether the server memory controller will accept the module without errors. Verify the platform requires exactly this ECC UDIMM profile before ordering.

Questions about this item

Will this 288-pin DDR4 UDIMM fit my Lenovo ThinkSystem server?

Yes — it is built for Lenovo ThinkSystem servers using 288-pin DDR4 ECC UDIMM slots.

What is the correct way to seat the module, and what step do people often miss?

Align the notch with the slot key, press straight down until both side clips click, then verify in BIOS that the 3200 speed and ECC are active.

When should I replace this 16 GB ECC module?

Replace it if the system logs uncorrectable ECC errors or if a DIMM fails the built-in memory self-test at boot.
