Lenovo Legion Tower compatible 16 GB DDR4

This 16 GB DDR4 2666 MHz module is built for Lenovo Legion Tower C530, C530-19ICB and T530-28ICB systems. It uses a 288-pin DIMM form factor with CL19 latency and 1.20 V operation. The unbuffered, non-ECC design fits standard desktop slots. Buyers upgrading compatible Lenovo towers can install this stick directly.

Single stick shifts bandwidth to single channel

The package contains one 16 GB stick, so adding it alone leaves the memory controller in single-channel mode. Matched pairs are recommended by the manufacturer to restore dual-channel bandwidth. All installed modules will run at the speed of the slowest stick or the CPU limit. Mixing brands is possible but not guaranteed to reach rated timings.

Check free slots and 64-bit OS before ordering

The supported platforms have two DIMM sockets and a 32 GB maximum capacity. Verify that a slot is free and that the system runs a 64-bit operating system to use more than 4 GB. The module has no heat spreader, so ensure case airflow is adequate. Confirm the exact model number matches your tower before purchase.

Questions about this item

Will the 16GB DDR4 2666MHz CL19 DIMM need replacement if I later add a second stick to reach 32GB?

The system supports up to 32GB across two slots; adding a matching 16GB module later will work without replacing this stick.

What speed limit appears first when the 2666MHz memory runs continuously in a Lenovo Legion Tower C530?

All installed modules run at the slowest speed present, so sustained use stays at 2666MHz unless a slower stick is added.

How much heat or extra power does the 1.2V unbuffered 2Rx8 module produce during all-day operation?

At 1.2V with no heat spreader, the module draws standard DDR4 power and runs cool enough for continuous use in the Legion Tower chassis.
