Compatible DDR3L kit for ThinkPad Edge E431

This 16 GB kit contains two 8 GB SODIMM modules built for the ThinkPad Edge E431 series 6277 and 6886. Each stick uses 204-pin DDR3L technology running at 1600 MHz with a CAS latency of 11. The unbuffered, non-ECC design matches the factory memory specification for these laptops.

Steady 1.35 V operation at 1600 MHz

The modules operate at 1.35 V, reducing heat output during extended workloads compared to standard 1.5 V DDR3. CL11 timing at 11-11-11 delivers consistent bandwidth for multitasking, virtual machines or large spreadsheets without throttling. The major-brand chipset maintains stability across long sessions.

Two-stick upgrade fills both slots

The kit populates both memory sockets for dual-channel performance and reaches the platform maximum of 16 GB. No heat spreader is fitted, keeping the low-profile height required by the slim chassis. Buyers needing more than 16 GB or a different form factor cannot use this kit.

Questions about this item

Does the 1.35 V DDR3L kit run cooler than standard 1.5 V DDR3 during all-day use?

DDR3L operates at 1.35 V, which reduces power draw and heat compared with 1.5 V DDR3, helping the ThinkPad Edge E431 stay cooler under sustained load.

Will the ThinkPad Edge E431 accept two 204-pin SODIMM sticks to reach 16 GB?

The Edge E431 has two SODIMM slots and supports up to 16 GB, so this 2 x 8 GB kit fills both slots for the maximum capacity.

Can I mix these CL11 1600 MHz modules with the original memory already in the laptop?

The kit is rated at CL11 1600 MHz; if the original modules share the same speed and timing the system will run in dual-channel mode at those settings.
