16GB DDR4 2666 SODIMM

This 16GB DDR4-2666 SO-DIMM module is built for Lenovo ThinkPad P52, P53, P72 and P73 workstations. It runs at 1.2V with CL19 timing in a 2Rx8 unbuffered configuration. The 260-pin stick installs directly into the memory slot.

Suits ThinkPad P-series owners

Buyers who need ECC memory for Xeon processors should look elsewhere, as this is a non-ECC module. Systems limited to lower speeds will run this stick at the slower rate. The single 16GB design fills one socket.

PC4-21300 speed rating

The module operates at the DDR4-21300 (2666MHz) data rate specified for these ThinkPad models. Mixing with slower memory will reduce overall system speed to the lowest installed module. A 64-bit operating system is required to address the full capacity.

Questions about this item

Does DDR4-2666 (PC4-21300) run at its rated speed in a ThinkPad P52?

Yes, the module is rated for DDR4-2666 (PC4-21300) and will operate at that speed if the processor and chipset support it; otherwise it downclocks to the highest speed the platform allows.

Will the 260-pin SODIMM fit the single memory slot in a ThinkPad P53?

The stick uses the standard 260-pin DDR4 SO-DIMM form factor and the P53 has one SODIMM socket, so it installs directly without adapters.

How is the module installed, and what step do people often miss?

Power off the laptop, remove the bottom cover, insert the SODIMM at an angle into the slot until the gold contacts are hidden, then press down until the side clips click; the step often missed is pushing firmly enough to engage both clips.
