System-specific DDR3L kit for Lenovo ThinkPad T550

This 16 GB kit contains two 8 GB SODIMM modules built for the Lenovo ThinkPad T550. Each stick runs at 1600 MHz with CL11 timing at 1.35 V. The unbuffered, non-ECC design matches the laptop’s two memory slots for a straightforward upgrade.

Two-module kit enables dual-channel operation

The pair of 8 GB sticks populates both slots, allowing the platform to run in dual-channel mode for improved memory bandwidth. The 204-pin DDR3L form factor fits the T550 without modification, and the 1.35 V rating aligns with the system’s low-voltage requirement.

Verify both slots are free before ordering

The T550 supports a maximum of 16 GB across its two sockets, so this kit fills the machine completely. If one slot already holds a module, you would need a single 8 GB stick instead. Confirm the laptop uses DDR3L SODIMM memory and that no larger capacity is required.

Questions about this item

Will the DDR3L SODIMM modules need any firmware updates or thermal-pad replacements over their lifespan?

No firmware updates are required for these unbuffered DDR3L SODIMM modules, and they ship without heat spreaders so no thermal-pad maintenance is needed.

What is the first limit reached when the memory runs at 1600 MHz continuously in the ThinkPad T550?

The CAS latency of CL11 at 1600 MHz is the primary timing constraint under sustained load.

How much power do the two 8 GB sticks draw at 1.35 V during all-day operation?

Each module operates at 1.35 V DDR3L voltage, reducing power draw compared to standard 1.5 V DDR3.
