System-Specific DDR4 SODIMM

This 16GB DDR4 2666 SODIMM is built for Lenovo ThinkCentre M820z all-in-one and P330 Tiny systems. It delivers a straightforward memory upgrade for compatible desktops. The module is unbuffered, non-ECC and operates at 1.2V.

DDR4 2666 SO-DIMM limits

The DDR4 2666 interface caps bandwidth at PC4 21300 and uses a 260-pin SO-DIMM form factor. CL19 timing and 19-19-19 latencies define the access speed ceiling. Two 16GB modules reach the platform maximum of 32GB across two sockets.

16GB single-module capacity

A single 16GB stick fills one slot and leaves the second socket open for a matching module. Buyers who need the full 32GB must add a second identical stick. Systems with only one slot cannot use this capacity.

Questions about this item

Should I choose the 16 GB module or add a second stick to reach 32 GB?

Each stick is 16 GB; the supported systems have two slots and a 32 GB maximum, so one module gives 16 GB and two give the full 32 GB.

What does the 2666 MHz rating deliver in the ThinkCentre M820z or P330 Tiny?

The modules run at DDR4 2666 (PC4 21300) with CL19 timing at 1.2 V, providing the rated bandwidth and latency inside those specific all-in-one and tiny desktops.

Does the 260-pin SO-DIMM interface limit speed or capacity in these Lenovo models?

The 260-pin DDR4 SO-DIMM form factor matches the two slots in the M820z and P330 Tiny, supporting the full 2666 MHz speed and up to the 32 GB system maximum.
