4 GB DDR3-1333 SODIMM for ThinkPad T420S
This 4 GB DDR3 SODIMM runs at 1333 MHz with CL7 latency and 1.5 V operation. It uses a 204-pin unbuffered, non-ECC design built with major-brand chips. The module is validated for Lenovo ThinkPad T420S models 4170, 4171, 4173 and 4174.
Suits owners refreshing a single slot in a T420S
The stick adds 4 GB to one of the two sockets, taking the system toward its 8 GB maximum. Buyers needing a matched pair for dual-channel operation or a full 8 GB upgrade should look at a two-module kit instead.
Stable throughput at CL7 under continuous load
The 7-7-7 timing delivers consistent bandwidth during long compile sessions or heavy multitasking without the latency spikes seen in higher-CAS modules. The 1.5 V rating keeps thermals modest inside the slim T420S chassis.

Preguntas sobre este artículo
What laptop model must I own for this 204-pin DDR3 SODIMM to fit?
This module is validated for the Lenovo ThinkPad T420S series, specifically sub-models 4170, 4171, 4173 and 4174.
How will this CL7 1333 MHz stick behave if I keep an existing 1600 MHz module in the second slot?
The faster module will down-clock to 1333 MHz and adopt the CL7 timings so both sticks run in sync.
How can I confirm the stick is running at CL7 7-7-7 timings after installation?
Open CPU-Z or the BIOS memory tab; the SPD and real-time tabs should show DDR3-1333, CL7 and 7-7-7 timing values.
