32GB DDR3 SODIMM kit for Lenovo ThinkPad W520

This 32GB kit contains four 8GB DDR3 1333MHz modules in a 204-pin SODIMM form factor. It runs at 1.5V with CL9 latency and is unbuffered, non-ECC memory. The kit is built for compatible Lenovo ThinkPad W520 Quad Core models 4270, 4276, 4282 and 4284.

System-specific upgrade for W520 and W701 series

The memory fits Lenovo ThinkPad W520 Quad Core models 4270, 4276, 4282 and 4284, plus ThinkPad W701 series 2500, 2541 and 2542. It suits owners of those laptops who want to reach the 32GB maximum on a 64-bit operating system. Builders working on other laptop models, desktops or servers cannot use these SODIMM modules.

DDR3 1333MHz CL9 1.5V specification

The modules operate at DDR3 1333MHz (PC3-10600) with 9-9-9 timing at 1.5V. This exact speed, voltage and latency combination determines whether the memory will run stably in the listed ThinkPad systems. A different DDR generation, voltage or timing will not be compatible.

Questions about this item

Should I buy the 32 GB (4 x 8 GB) kit or add a smaller capacity to my ThinkPad W520?

The W520 has four SODIMM slots and supports up to 32 GB with a 64-bit OS, so the 4 x 8 GB kit fills every slot and reaches the maximum supported capacity.

What does the 1333 MHz CL9 rating deliver in daily use on a W520?

At 1333 MHz with 9-9-9 timings and 1.5 V, the modules run at the W520's native memory speed, giving stable throughput for typical workloads without overclocking.

Is the 204-pin DDR3 SO-DIMM interface the right fit for my ThinkPad W520 or W701 series?

Yes — both the W520 (4270, 4276, 4282, 4284) and W701 (2500, 2541, 2542) series use 204-pin DDR3 SO-DIMM slots, so these unbuffered non-ECC modules install directly.
