Lenovo ThinkPad L520 16GB Kit

This 16GB kit contains two 8GB DDR3 1333MHz SO-DIMM modules built for the Lenovo ThinkPad L520 series including models 5016, 5017, 7859 and 7860. The memory runs at 1.5V with CL9 latency and uses unbuffered, non-ECC chips. It is a direct upgrade for those specific notebooks.

Suits ThinkPad L520 owners; not for other systems

Buyers with a compatible ThinkPad L520 can install both modules to reach the 16GB maximum. It is not for laptops that require ECC or registered memory, machines limited to 8GB total capacity, or notebooks that use a different pin count or voltage. Apple MacBook Pro 13.3 inch 2.4GHz and 2.8GHz models are also listed as compatible.

204-pin DDR3 SO-DIMM form factor

The decisive specification is the 204-pin DDR3 SO-DIMM interface. Only systems accepting this exact module type and voltage will recognise the kit. Verify your laptop uses 204-pin DDR3 slots before ordering.

Questions about this item

Does the 204-pin DDR3 SO-DIMM form factor fit the two memory slots in a Lenovo Thinkpad L520 5016?

Yes, each 8 GB module uses the standard 204-pin DDR3 SO-DIMM layout that matches the two slots in the Thinkpad L520 5016 series.

What is the correct way to seat both 8 GB sticks so the laptop recognises the full 16 GB?

Insert each module at the same angle until the gold edge contacts disappear, then press down firmly until both side clips click — partial insertion is the most common reason only 8 GB appears.

When should the two modules be removed and re-seated to maintain reliable operation?

Re-seat the pair if the system develops random crashes, fails to POST, or shows memory errors after a major BIOS update or after the laptop has been dropped.
