System-specific DDR4 upgrade

This 16 GB DDR4 module is built for Lenovo ThinkStation P330 Gen 2 workstations in both SFF and tower chassis. It targets users who need to expand memory on these exact platforms without compatibility guesswork. The single stick delivers 16 GB at 2666 MHz with CL19 timings.

Fits four DIMM slots, max 128 GB

The workstation provides four 288-pin slots and supports up to 128 GB total capacity. Installing this unbuffered, non-ECC DIMM occupies one slot and leaves three free for further expansion. A 64-bit operating system is required to address more than 4 GB of memory.

Steady throughput at standard voltage

Running at 1.20 V, the module maintains its rated 2666 MHz speed under sustained workloads rather than only in short bursts. All installed memory operates at the speed of the slowest module or the processor limit, so matched pairs are recommended for optimal throughput.

Questions about this item

Will the CL19 latency limit throughput during sustained workloads?

CL19 is the rated timing at 2666 MHz; the system runs all installed modules at the slowest speed present, so matching pairs avoid a lower ceiling.

How much heat or power does a 1.20 V 16 GB stick add when running all day?

At 1.20 V the module draws standard DDR4 power and has no heat spreader; typical case airflow is sufficient for continuous operation.

Which motherboard slots and CPU memory controller are required for this 288-pin DIMM to work?

It fits the four 288-pin DDR4 slots in a ThinkStation P330 Gen 2 (SFF or Tower) and needs a 64-bit OS to use more than 4 GB.
