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.

商品問答

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.
