ThinkPad P50s 16 GB DDR3 SODIMM

This 16 GB DDR3 SODIMM is built for the Lenovo ThinkPad P50s and runs at 1600 MHz with CL11 timing. It uses a 204-pin unbuffered non-ECC design at 1.5 V and carries a 2Rx8 rank configuration. The module is sold as a single 16 GB stick for straightforward capacity upgrades.

DDR3 1600 MHz SO-DIMM limits

The DDR3 SO-DIMM interface tops out at 1600 MHz and 1.5 V on this platform. Only two memory sockets exist, so total system memory cannot exceed 32 GB. Dual-channel operation requires paired modules; a single stick runs in single-channel mode. A 64-bit operating system is required to address the full capacity.

16 GB single-module headroom

One 16 GB module leaves one free socket for a second stick to reach the 32 GB maximum. Buyers who want more storage than 32 GB cannot use this platform. Systems with 4 GB already installed may see only 3.5 GB recognised depending on memory allocation.

Questions about this item

Should I buy this single 16GB stick or look for a pair of 8GB modules for my ThinkPad P50s?

The P50s has two sockets and a 32GB ceiling; a single 16GB stick leaves one slot free for a matching module later, while a pair of 8GB sticks would fill both slots now and enable dual-channel throughput immediately.

Will the advertised 1600MHz speed actually run at that rate once installed in the P50s?

The module is rated DDR3-1600 CL11 at 1.5V; the P50s memory controller supports that speed, so the stick will operate at 1600MHz without manual tuning.

Is the 204-pin DDR3 SO-DIMM interface the limiting factor for total capacity in this laptop?

Yes — the P50s uses two 204-pin DDR3 SO-DIMM slots, and the platform maximum is 32GB, so two 16GB modules like this one reach that ceiling.
