Ready-to-install DDR3 kit

This 8 GB kit (two 4 GB modules) is built for the Lenovo ThinkPad L520 models 5016, 5017, 7859 and 7860. It uses 204-pin DDR3 SO-DIMM modules running at 1333 MHz with CL7 timings at 1.5 V. The sticks are unbuffered, non-ECC and carry a 2Rx8 organisation. Install both modules to reach the system’s 8 GB maximum across its two sockets.

Not for other laptops or desktop boards

The modules are validated only for the four ThinkPad L520 series listed above. Buyers who need memory for a different notebook, a desktop motherboard or a server should look elsewhere. The kit also does not suit anyone who requires ECC error correction or registered modules. Capacity is fixed at 8 GB, so systems that support more memory cannot be expanded with this package.

204-pin DDR3 SO-DIMM form factor

The 204-pin SO-DIMM edge connector is the single specification that decides fitment. If the target machine uses a different pin count, a different DDR generation or a DIMM slot, the modules will not seat. Match the 204-pin DDR3 SO-DIMM requirement exactly before ordering.

Questions about this item

What comes in the box and is anything else needed to install this kit?

The box contains two 4 GB DDR3 SODIMM modules. No extra parts or tools are required for installation in a compatible laptop.

Should I pick this 8 GB kit or look for a different capacity for my ThinkPad L520?

This 8 GB kit matches the maximum supported memory and fills both slots of the L520 5016, 5017, 7859 and 7860 series.

The listing says DDR3 1333 CL7 — what speed will I actually see in Windows?

The modules run at 1333 MHz with 7-7-7 timings at 1.5 V, so the system will report DDR3-1333 operation.
