System-Specific DDR3 Upgrade

This 4 GB SODIMM is built for Lenovo ThinkPad T420 models 4177, 4178, 4180 and 4236. It targets owners who need a single-module capacity increase without replacing both factory slots. The module uses 204-pin DDR3 technology at 1333 MHz with CL7 timing. It is not for systems that require ECC, registered memory or a different DDR generation.

Build Integration

The stick fits one of the two SO-DIMM sockets in the supported ThinkPads and runs at the standard 1.5 V. It leaves the second slot free for an additional 4 GB module to reach the platform maximum of 8 GB. No heat spreader is present, so it clears tight chassis clearances. Buyers whose laptops already contain two modules cannot add this without removing one.

Included Module

The package contains one 4 GB memory stick backed by the manufacturer’s lifetime warranty when purchased directly. There are no cables, tools or software utilities supplied. The single-module kit lets you upgrade in 4 GB increments rather than forcing a matched pair purchase.

商品問答

What speed ceiling does the 1.5 V DDR3 1333 module hit during long workloads?

The module runs at DDR3 1333 (PC3 10600) with CL7 timing, so sustained throughput is limited by that 1333 MT/s data rate and the 1.5 V operating voltage.

How much heat or fan noise does the unbuffered 2Rx8 stick add when the laptop runs all day?

The SODIMM has no heat spreader and draws standard 1.5 V DDR3 power, so it adds negligible heat and no audible noise; the system fan curve stays unchanged.

Which ThinkPad models and slot count does this 204-pin SODIMM fit without extra parts?

It is validated for ThinkPad T420 4177, 4178, 4180 and 4236 series, which have two DDR3 SODIMM slots supporting up to 8 GB total.
