16GB DDR3 1333MHz Kit for ThinkPad W520

This kit provides 16GB of DDR3 memory in two 8GB SODIMM modules. It runs at 1333MHz with CL9 timing at 1.5V. The unbuffered, non-ECC design matches the requirements of compatible Lenovo ThinkPad W520 models.

Suits W520 owners filling both slots

Buyers upgrading a ThinkPad W520 series laptop with two memory sockets can use this matched pair. Systems needing ECC error correction, registered modules, or a different pin count should look elsewhere.

Dual-rank 2Rx8 organisation

Each 8GB module uses a 2Rx8 configuration with major-brand chips. This rank structure is the key specification that determines correct operation in the supported W520 variants.

Questions about this item

Will 1333 MHz DDR3 run at that speed inside a ThinkPad W520?

The W520 memory controller supports DDR3-1333, so both 8 GB modules operate at the rated 1333 MHz with CL9 timing.

Does the 204-pin SO-DIMM interface limit total capacity to 16 GB?

Each 204-pin slot accepts an 8 GB stick; with two sockets the W520 reaches 16 GB using this kit.

What physical clearance do the two 8 GB sticks need in the W520?

Standard-height SO-DIMMs without heat spreaders fit the two memory slots under the W520 access panel.
