16 GB DDR4-2933 ECC unbuffered DIMM for Lenovo-compatible server upgrades
This 16 GB DDR4-2933 module uses 1Rx8 organisation and runs at 1.20 V with ECC error correction. It is built from major-brand Samsung, SK Hynix or Micron components and carries the Lenovo part number 4X71B32812. The unbuffered 288-pin design targets administrators who need to expand memory in compatible Lenovo platforms.
Rated for continuous operation at 2933 MT/s, the module sustains PC4-23400 bandwidth under prolonged workloads rather than only in brief bursts. ECC circuitry corrects single-bit errors on the fly, preserving data integrity during extended compute or virtualisation tasks. The 1.20 V supply helps keep thermal output predictable inside dense server chassis.
The stick installs like any standard 288-pin DDR4 UDIMM; no extra configuration is required on supported Lenovo systems. Orders are fulfilled with identically matched modules, eliminating the mismatch risk that can cause boot failures or unstable timings. Buyers who need registered DIMMs, higher capacities or non-Lenovo qualified parts should look elsewhere.
