8GB DDR4 2666 Module

This Crucial desktop memory module provides 8GB of DDR4 capacity at 2666 MT/s with CL19 timing. It operates at the standard 1.20V and uses an unbuffered, single-ranked x8 design. The 288-pin DIMM is built on Micron chips and carries a green PCB without LED lighting.

Who This Suits

The kit is suited for a dual-channel desktop upgrade where two identical modules are installed together. Systems that require ECC or registered memory should look elsewhere, as this module is non-ECC and unbuffered.

Build Fit

The module fits any desktop board with a DDR4 288-pin slot and runs at the JEDEC 1.20V level without extra voltage. Its standard height leaves clearance for most CPU coolers, while the dual-channel kit simplifies pairing for increased bandwidth.

Questions about this item

What motherboard slot does this 288-pin DDR4 DIMM require?

It fits a standard desktop DDR4 DIMM socket; the board must support 2666 MT/s operation at 1.20 V.

Will this CL19 2666 MT/s kit run with my existing 2133 MT/s DDR4 modules?

Yes, the faster modules will down-clock to match the slowest installed speed and the looser timings of the older sticks.

How can I confirm the kit is running in dual-channel mode after installation?

Open the system BIOS or a hardware utility; the memory section should report dual-channel operation at 2666 MT/s with 19-19-19 timings.
