System-specific DDR3 SODIMM kit

This 16 GB kit contains two 8 GB DDR3-1333 SODIMM modules built for the Lenovo ThinkPad T420 series. It targets owners of the 4177, 4178, 4180 or 4236 models who want to reach the platform maximum of 16 GB.

DDR3-1333 bandwidth ceiling

The DDR3-1333 (PC3-10600) interface caps memory throughput at the speed these modules deliver. Builders needing higher bandwidth must choose a laptop platform that supports a faster memory standard.

Two-slot maximum capacity

The T420 provides only two SODIMM sockets, so this 2 x 8 GB kit fills every slot to hit the 16 GB limit. Buyers who want more memory capacity cannot add modules beyond this configuration.

商品問答

Should I choose the 2x8GB kit or a single 16GB module for my ThinkPad T420?

The T420 has two memory sockets and a 16GB maximum, so the 2x8GB kit fills both slots for dual-channel operation and reaches the system limit.

What does the 1333MHz rating mean once installed in a ThinkPad T420?

The modules run at DDR3-1333 (PC3-10600) with CL9 timing at 1.5V, matching the T420's native memory controller speed.

Will the 204-pin DDR3 SO-DIMM interface work in my T420 4177, 4178, 4180 or 4236 series?

Yes, these sticks are 204-pin DDR3 SO-DIMMs, the exact form factor and generation required by those ThinkPad T420 models.
