16 GB DDR4 2400 SODIMM for Lenovo ThinkPad

This 16 GB DDR4 2400 SO-DIMM module is built for specific Lenovo ThinkPad models. It runs at 2400 MHz with CL17 timing at 1.2 V. The stick uses a 260-pin unbuffered non-ECC layout and is sold as a single piece upgrade.

Suits ThinkPad P51s P52s T470 T470p owners adding

Buyers with a compatible ThinkPad P51s, P52s, T470 or T470p can install this module to reach the platform maximum of 32 GB. It is not for systems that require ECC or registered memory, nor for laptops that only accept smaller SO-DIMM capacities.

Check your ThinkPad model number

Verify the exact model code such as 20HB, 20JY, 20LB, 20HD, 20HE, 20JM, 20JN, 20J6 or 20J7 appears on your device. Confirm an empty 260-pin SO-DIMM socket is available and that the system BIOS recognises 16 GB modules.

Questions about this item

Does my Lenovo Thinkpad need a free 260-pin SODIMM slot to install this 16GB DDR4 module?

Yes, the module uses the 260-pin DDR4 SO-DIMM form factor and requires an available SODIMM slot in a compatible Thinkpad such as the P51s, P52s, T470 or T470p.

Can I keep an existing DDR4 2400 CL17 stick in the second slot alongside this 16GB module?

Yes, the laptop supports two SODIMM sockets up to 32GB total, so a matching 2400 MHz CL17 module can run together with this 16GB stick in dual-channel mode.

How do I confirm the memory is running at 2400 MHz with CL17 timing after installation?

Open Task Manager or a system-information tool and verify the speed reads 2400 MHz and the timings show 17-17-17 for the installed 16GB module.
