16 GB DDR4 2666 MHz module for Lenovo Legion

This 16 GB DDR4 2666 MHz CL19 UDIMM is built for Lenovo Legion T530 and T730 desktops that use 288 pin non ECC memory. It runs at the standard 1.2 V JEDEC voltage and carries a 2Rx8 rank layout. The module is designed as a direct upgrade for the listed Legion models.

Steady operation at rated speed and latency

The memory operates at its rated 2666 MHz with CL19 timings under continuous workloads because it follows JEDEC specifications without overclocking headroom. No heat spreader is fitted, so the sticks rely on normal chassis airflow to maintain stable temperatures during extended multitasking or large file handling.

Verify slot count and maximum capacity first

Check how many 288 pin DDR4 slots your Legion T530 or T730 has free and confirm the total memory limit supported by that specific model before ordering. The module is backward compatible with 2133 MHz and 2400 MHz systems but will run at the lower speed if installed in those platforms.

Questions about this item

Does the 1.2V 16GB DDR4 module run hot or noisy when the Legion T530 or T730 is under load all day?

The module has no heat spreader and operates at the standard 1.2V JEDEC voltage, so it adds minimal heat and makes no noise of its own.

What must already be in my Legion T530-28ICB or T730-28ICO for this 288-pin UDIMM to work?

You need a free DDR4 UDIMM slot on the motherboard; the module is unbuffered, non-ECC and keyed for 288-pin desktop sockets.

Will this CL19 2666MHz stick downclock reliably alongside the 2133MHz or 2400MHz modules I already have installed?

Yes, the spec sheet confirms backward compatibility with 2133MHz and 2400MHz, so the new stick will match the speed of the slower modules.
