Crucial 16GB DDR4-2666 UDIMM
This 16 GB DDR4 module runs at 2666 MHz with CL19 latency and 1.2 V operation. The 288-pin unbuffered design uses a single-rank x8 layout without ECC or registered buffers. It suits standard desktop memory slots that accept PC4-21300 speeds.
Who this suits and who should look elsewhere
Ideal for builders upgrading a desktop that supports DDR4-2666 non-ECC UDIMM memory. Not suitable for systems requiring ECC error correction, registered modules, or higher frequencies beyond 2666 MHz. Buyers needing capacities above 16 GB per slot should consider other options.

Questions about this item
Will this 288-pin DDR4 UDIMM fit my desktop motherboard slot?
The module uses the standard 288-pin DDR4 UDIMM form factor used by virtually all current desktop boards. Check your manual to confirm it accepts unbuffered non-ECC memory.
What is the correct way to seat the module so the system recognises the full 16 GB?
Align the notch with the slot key, press straight down until both side clips click shut. The most common mistake is stopping when it feels tight but before the clips engage.
