16GB DDR4 SODIMM for Lenovo Workstations

This 16GB DDR4 2666MHz SODIMM module is built for Lenovo ThinkPad P1 and X1 Extreme second-generation laptops. It uses a 260-pin unbuffered non-ECC design with CL19 timings at 1.2V. The single-stick kit suits owners who need a direct replacement or a capacity increase without changing the platform.

DDR4 2666 SO-DIMM speed ceiling

The DDR4 2666 interface caps data rate at 2666 MT/s with a PC4 21300 bandwidth rating. Installed modules will run at the slowest speed present in the system or allowed by the processor memory controller. Mixing faster sticks provides no benefit because the bus cannot exceed this specification.

16GB single rank headroom

One 16GB module fills a single slot and leaves three sockets open toward the 128GB platform maximum. A 64-bit operating system is required to address more than 4GB. Buyers who want more storage than one stick provides must add matched pairs to reach higher capacities.

Frågor om den här produkten

Is the 16 GB module sold individually or as a matched pair?

This listing is for a single 16 GB stick (1X16GB). To run in dual-channel mode you would need to add a second identical module.

Will the DDR4 2666 rating actually run at 2666 MHz in a ThinkPad P1 or X1 Extreme?

The module is rated at 2666 MHz (PC4 21300). The final speed will be limited by the processor's memory controller and any slower modules already installed.

Does the 260-pin SODIMM interface limit bandwidth compared to desktop DIMMs?

The 260-pin SODIMM form factor carries the same DDR4 2666 signal as desktop DIMMs; the pin count only reflects the smaller physical size for laptops.
