Perfect for Lenovo ThinkPad upgrades

This 2GB DDR3 SODIMM module runs at 1333 MHz with CL7 timings and 1.5V operation. It is built for the ThinkPad L412, L420, L512 and L520 models. The unbuffered, non-ECC design uses a single 1Rx8 rank with major brand chips. It installs directly into the 204-pin slot.

Check your laptop before ordering

Confirm the specific ThinkPad model matches the L412, L420, L512 or L520 series. Verify the system currently uses DDR3 SO-DIMM memory and has an available 204-pin slot. Ensure the BIOS supports 1333 MHz speed and CL7 latency at 1.5V. The module is a single 2GB stick, not a kit.

Replaces slower or smaller DDR3 modules

Upgrading from a lower capacity stick or slower DDR3 speed yields a noticeable jump in multitasking headroom. The CL7 timing improves responsiveness over standard CL9 modules at the same frequency. Buyers needing more than 2GB total capacity or dual-channel kits should look elsewhere. This is a single module for a specific slot.

Questions about this item

Does the box contain just the memory stick or any extra brackets or tools?

The package includes one 2 GB DDR3 1333 SODIMM module; no brackets, screws or tools are supplied.

Should I pick the CL7 version or a CL9 module for my ThinkPad L420?

This kit runs at CL7 7-7-7 timing; both CL7 and CL9 will work, but CL7 gives slightly lower latency.

Will the rated 1333 MHz speed actually run at that frequency in my L512?

The module is rated DDR3 1333 (PC3 10600) and will operate at 1333 MHz if the platform supports it.
