64GB DDR4 SO-DIMM kit for ThinkPad P-series

This 64GB kit contains four 16GB DDR4 2666 CL19 modules built to 260-pin SO-DIMM specification. It is designed for owners of Lenovo ThinkPad P52, P53, P72 or P73 mobile workstations who need to reach the platform maximum of 128GB across four sockets. The modules run at 1.2V, are unbuffered and non-ECC, and use a 2Rx8 organisation.

Suited for ThinkPad P52-P73 upgrades.

The kit suits professionals expanding memory in the listed ThinkPad models where the CPU supports non-ECC SO-DIMMs. Buyers whose processor requires ECC memory, or who are upgrading a desktop motherboard that takes UDIMMs, cannot use these modules. The 260-pin form factor fits only compatible SO-DIMM slots.

CL19 latency at DDR4 2666

The decisive specification is the CL19 timing at 2666 MT/s, which sets the memory controller speed for all installed sticks. Every module in the kit matches this latency so the system runs at a consistent rate without down-clocking to a slower JEDEC profile.

Questions about this item

Will the 260-pin DDR4 SO-DIMM modules fit the memory slots in a ThinkPad P52 or P73?

Yes, the 260-pin DDR4 SO-DIMM form factor matches the slots used in the ThinkPad P52, P53, P72 and P73 models listed for this kit.

What is the correct way to install the four 16 GB sticks so the laptop recognises the full 64 GB?

Populate all four sockets with the matched 2Rx8 modules; the system will run at DDR4-2666 CL19 1.2 V once the sticks are fully seated and the retaining clips click.

When would the memory need to be replaced or upgraded beyond this 64 GB kit?

The platform supports up to 128 GB across its four slots, so replacement is only needed if a fault occurs or you later expand to the maximum capacity.
