4GB DDR3L SODIMM for select Lenovo IdeaPad models

This 4GB DDR3L 1600 SODIMM module is built for specific Lenovo IdeaPad 300 and 500 series laptops that accept 204-pin DDR3L memory at 1.35V. It is a JEDEC-standard, non-ECC unbuffered module with CL11 latency and 1Rx8 rank. The single 4GB stick installs into one SODIMM slot to add capacity.

Who this suits and who should look elsewhere

This upgrade fits owners of the listed IdeaPad 300-15ISK, 300-17ISK, 300S-14ISK, 305-15IBD, 305-15IHW, 500-14ACZ and 500S-13ISK models needing more memory for everyday multitasking. Buyers whose laptops require a different pin count, voltage, DDR generation or higher capacity per module should look elsewhere.

The specification that decides compatibility

The module uses 204-pin DDR3L at 1600 MT/s (PC3L-12800) with 1.35V operation and CL11 timing; if the target laptop does not support this exact combination the memory will not work.

Questions about this item

How can I verify the 4GB DDR3L 1600 module is running at 1.35V and CL11 after installation?

Enter the system BIOS or UEFI and check the memory information screen; it should report 1600 MT/s, 1.35 V and CAS latency 11 for the installed SODIMM.

What comes in the package and do I need any extra parts for the upgrade?

The box contains one 204-pin DDR3L SODIMM module; no additional components or tools are required for installation.

Which capacity should I choose if my IdeaPad 300-15ISK currently has one empty slot?

This 4 GB module matches the listed compatibility for the 300-15ISK; add it to the free slot to increase total memory by 4 GB.
