Capacity and compatibility

This 16 GB DDR5 module runs at 4800 MHz with CL40 latency at 1.1 V. It is an unbuffered non‑ECC DIMM built with major‑brand chips and validated as a replacement for IBM‑Lenovo part 4X71K53891.

Build fit and platform freedom

The 288‑pin DDR5 form factor slots directly into any desktop board that supports DDR5 4800 PC5‑38400 memory. Using a single 16 GB stick leaves remaining slots open for future expansion while delivering immediate capacity for AMD and Intel platforms.

Sustained workload behaviour

Standard 1.1 V operation keeps thermals modest during extended multitasking or heavy background tasks. Rigorous quality testing ensures stable throughput over long sessions without voltage scaling or throttling.
