ThinkPad P52 P53 P72 P73 DDR4 upgrade

This 8 GB SODIMM is built for Lenovo ThinkPad P52 P53 P72 P73 mobile workstations. It targets professionals who need to expand system memory for larger datasets or virtual machines. The module is validated for these specific models only.

CL19 2666 MHz 260-pin non-ECC spec

The stick runs at DDR4 2666 PC4 21300 with CL19 19-19-19 timing at 1.2 V. It is unbuffered non-ECC 1Rx8 using major-brand chips. This exact speed and latency combination decides whether the laptop will accept the module without down-clocking.

Tool-free slot access no heat spreader

Installation requires opening the bottom panel and pressing the module into the single 260-pin slot until the clips lock. No heat spreader means clearance is tight but standard. Mixing with existing RAM forces all memory to run at the slowest installed speed.

Questions about this item

How does the 2666 MHz speed and CL19 timing affect real-world performance in my ThinkPad?

The module runs at DDR4 2666 with CL19 timing; actual throughput depends on your processor and whether other installed memory runs at the same speed.

What does the 260-pin SODIMM form factor mean for installation in a ThinkPad P52, P53, P72 or P73?

It fits the standard 260-pin DDR4 SO-DIMM slot used in those models; the stick is unbuffered, non-ECC and 1.2 V, matching the factory specification.

Does the single 8 GB stick leave room to add another module later?

Yes, the kit contains one 8 GB module, so a second slot (if your specific model has two) remains free for a matching upgrade.
