16GB DDR4 UDIMM for desktop upgrades

This single 16GB unbuffered DIMM uses standard DDR4 technology at 1.20V. It fits 288-pin motherboard slots and is intended for desktop systems needing additional memory capacity.

DDR4-2666 PC4-21300 bus speed limits

The module operates at DDR4-2666 with a PC4-21300 data rate and CL19 latency. System memory speed will match the lowest rated module or the motherboard maximum if that value is lower.

Questions about this item

Should I pick this 16 GB module or look for a different capacity?

The module provides 16 GB in a single stick, so you can start with one and add a second later if your board has a free slot.

What does the 2666 MT/s rating mean once the stick is installed?

The memory will run at 2666 MT/s if the motherboard supports that speed; otherwise it will drop to the highest speed the board allows.

Is the 288-pin DDR4 interface compatible with my desktop board?

Yes, the 288-pin UDIMM form factor is the standard desktop DDR4 interface and fits any board with DDR4 DIMM slots.
