System-specific DDR3 SODIMM for ThinkPad W520

This 8 GB module is built for Lenovo ThinkPad W520 models 4270, 4276, 4282 and 4284. It uses a 204-pin DDR3 SO-DIMM form factor running at 1333 MHz with CL9 timings and 1.5 V operation. The stick is unbuffered, non-ECC and organised as 2Rx8 using major-brand chips.

Check your ThinkPad W520 slot count

The W520 series provides two SODIMM sockets with a maximum supported capacity of 16 GB. Verify how many slots are already populated and whether the existing modules are DDR3 1333 MHz non-ECC unbuffered types. Matching speed, voltage and rank organisation helps avoid boot issues or down-clocking.

Ideal for W520 owners adding

This single 8 GB stick suits users upgrading one slot or replacing a failed module in the listed ThinkPad models. Buyers needing a matched pair for dual-channel performance or a total capacity above 16 GB should look at a two-module kit or a different platform.

商品問答

Does the package include anything besides the single 8 GB DDR3 1333 MHz SODIMM stick?

No. The box contains only one 204-pin unbuffered non-ECC module rated at 1.5 V with CL9 timing. No tools, adapters or extra sticks are supplied.

My ThinkPad W520 has two SODIMM slots and supports 16 GB maximum. Should I buy one 8 GB module or two?

For 16 GB total you need two 8 GB modules. One module gives 8 GB; adding a second fills the second slot and reaches the 16 GB limit.

The module is rated PC3-10600 1333 MHz CL9. Will it actually run at that speed once installed?

Yes. The W520 memory controller supports DDR3 1333 MHz, so the stick operates at its rated 1333 MHz with 9-9-9 timings at 1.5 V.
