A-Tech 4GB DDR3 1600MHz CL11 1.5V 240-Pin 1Rx8 for IBM-Lenovo 0A65729 888015710 Desktop RAM

Capacity and fit

This is a single 4 GB DDR3 module built to the 240-pin DIMM standard and rated for 1600 MHz operation at CL11 latency. It runs at the standard 1.5 V and uses unbuffered non-ECC chips, making it a direct drop-in for desktops that accept DDR3 UDIMM memory.

Upgrade path

It replaces the IBM-Lenovo part numbers 0A65729 and 888015710, so owners of those systems can restore or expand memory without hunting for discontinued OEM sticks. The jump is worth it when the machine still runs on 2 GB or 4 GB total and struggles with modern multitasking loads.

Sustained behaviour

Major-brand chips and full QA testing keep timings stable during long sessions, preventing the slowdowns that appear when lesser modules overheat or develop errors. Unbuffered topology means the memory controller sees consistent latency whether the workload lasts seconds or hours.
