4GB DDR3 desktop module for Lenovo systems

This 4GB DDR3 DIMM runs at 1600MHz with CL11 latency and 1.5V standard voltage. It is an unbuffered, non-ECC module built with major-brand chips. The 240-pin form factor fits compatible IBM-Lenovo desktops that specify part numbers 03T6566, 2PQ8640 or 41U6043.

Sustained load behaviour

The module operates at the tested frequency of 1600MHz under continuous workloads without throttling. Standard DDR3 voltage of 1.50V keeps power draw predictable during extended sessions. Unbuffered topology avoids registered latency overhead, so multitasking responsiveness remains consistent over time.

Build quality and daily use

Each stick undergoes quality-assurance testing before shipment to verify reliability. The 240-pin DIMM connector ensures a secure seat in standard desktop slots, reducing the risk of intermittent contact. Major-brand chipset construction supports stable operation across repeated install and remove cycles.
