Lenovo G505S DDR3L SODIMM kit

This 16 GB kit contains two 8 GB DDR3L SODIMM modules built for the Lenovo Essential G505S. Each stick runs at 1600 MHz with CL11 timing at 1.35 V. The unbuffered, non‑ECC design matches the laptop's two memory slots.

Tool‑free slot access

Installation requires opening the laptop's memory compartment and pressing each 204‑pin module into place until the side clips lock. The low‑profile sticks have no heat spreader, so they fit the tight SODIMM sockets without clearance issues. Handle the gold contacts by the edges to avoid contamination.

Ideal for G505S max‑out

Buyers upgrading a Lenovo Essential G505S to the full 16 GB supported capacity will use both slots with this matched pair. Systems that need ECC, registered DIMMs, higher voltage DDR3, or a different pin count should look at something else.

Questions about this item

How can I confirm the memory is running at 1600 MHz with CL11 timing after installation?

Open Task Manager or CPU-Z; the SPD tab should show 1600 MHz, DDR3L 1.35 V, and 11-11-11 latency for each 8 GB module.

The kit lists two 8 GB sticks — are any tools, screws, or extra brackets required to fit them into the Lenovo Essential G505S?

Only the two SODIMM modules are included; the laptop uses tool-free memory slots so no extra hardware is needed.

My G505S has two slots supporting 16 GB total — is this 2 x 8 GB kit the correct way to reach that maximum?

Yes, the system maxes at 16 GB across two sockets, so this matched pair fills both slots for the full capacity.
