Compatible ThinkPad upgrade

This 16GB DDR4 SODIMM is built for the Lenovo ThinkPad P50 and T460s. It delivers a straightforward memory increase for owners of those specific models who want more capacity for multitasking. The module is new and tested to meet OEM specifications for those systems.

DDR4 2133 CL15 limits

The stick runs at 2133MHz with CL15 latency and 1.2V operation under the JEDEC PC4-17000 standard. It is non-ECC, unbuffered and uses a 2Rx8 rank structure without a heat spreader. Systems that require registered memory, ECC support or a different voltage cannot use this module.

Check slots and maximum

Verify how many 260-pin slots your ThinkPad P50 or T460s has free and what the manufacturer lists as the maximum supported memory. The module is a single 16GB unit, so total capacity depends on available slots and the system’s own limit. Buyers needing ECC, registered DIMMs or a different form factor should look elsewhere.

Questions about this item

Should I pick the 16GB DDR4-2133 CL15 stick or look for a different capacity?

This part is a single 16GB 260-pin SODIMM; choose it when your ThinkPad P50 or T460s has a free slot and the service manual lists 16GB modules as supported.

What does the 2133MHz rating actually deliver once the module is installed?

The stick runs at DDR4-2133 with CL15 timing at 1.2V, so the memory controller will operate at that speed and latency unless the BIOS down-clocks it to match the slowest installed module.

How does the PC4-17000 label relate to the SODIMM interface and what bandwidth ceiling does it set?

PC4-17000 is the JEDEC bandwidth designation for DDR4-2133, meaning the 260-pin SODIMM interface can move up to 17,000 MB/s in dual-channel mode when the platform supports it.
