16GB DDR5-4800 for Lenovo 4X71K53893

This 16GB DDR5-4800 module is an unbuffered, non-ECC DIMM built as a direct replacement for Lenovo part 4X71K53893. It runs at 4800 MT/s with PC5-38400 bandwidth and standard 1.1 V operation. The stick uses major-brand DRAM ICs in a 1Rx8 layout and has no heat spreader.

Suits Lenovo desktops needing DDR5-4800 non-ECC

It fits Lenovo desktops that specify the 4X71K53893 part and accept 288-pin DDR5 DIMMs at 1.1 V. Systems requiring ECC, registered modules, or a different DDR generation will not work with this stick. Check the motherboard manual for slot population rules before ordering.

DDR5-4800 non-ECC 288-pin DIMM at 1.1 V

The single specification that decides compatibility is the DDR5-4800 non-ECC unbuffered 288-pin DIMM running at 1.1 V. If your Lenovo desktop calls for that exact combination, this 16GB module will slot in and run at the rated 4800 MT/s speed.
