8GB DDR3L SODIMM Kit

This 8GB kit contains two 4GB SODIMM modules rated at DDR3L 1600 (PC3L 12800) with CL11 timings and 1.35V operation. The 204-pin unbuffered non-ECC memory uses major-brand chipsets in a 1Rx8 configuration. It is built as a system-specific upgrade for compatible Lenovo ThinkPad notebooks.

Suits listed ThinkPad models; not for other laptops

The kit is validated for ThinkPad Edge E520, ThinkPad Edge L330, ThinkPad L421 and U31 series systems. Buyers with different notebook models or desktop platforms should look elsewhere, as the 204-pin SODIMM form factor and DDR3L voltage will not fit or function in incompatible hardware.

8GB maximum capacity across two slots

The supported platforms accept a maximum of 8GB total memory using one or two SODIMM sockets. This 2x4GB kit fills both slots to reach that limit, so no further expansion is possible on these machines.
