8GB DDR4 2666MHz Desktop Module

This 8GB DDR4 DIMM runs at 2666MHz and is built for desktop systems. It suits owners who want a straightforward capacity increase without moving to higher speeds or server-class parts. The single module leaves other slots free for future expansion if the board supports it.

288-Pin Unbuffered Non-ECC Build

The module uses the standard 288-pin DDR4 form factor and operates at 1.2V. It is unbuffered and non-ECC, so it fits consumer desktop boards that accept regular UDIMMs. The pin layout matches the Micron MTA8ATF1G64AZ series it replaces, making physical installation direct.

2666MHz Speed Rating

The tested frequency is 2666MHz with a PC4-21300 data rate. This speed decides whether the module matches the motherboard's supported memory specification. Systems that require a different DDR4 speed or that only accept registered ECC memory will not work with this part.

Questions about this item

Does the DDR4 2666 PC4-21300 interface cap the module at 2666 MT/s in practice?

Yes, the module is rated for 2666 MT/s and the PC4-21300 designation confirms that maximum transfer rate.

What physical slot and pin count does this 288-pin DIMM require on the motherboard?

It fits a standard DDR4 DIMM socket with 288 pins; the notch position matches the DDR4 keying.

What is the correct installation step for this unbuffered 1.20 V module, and what mistake should be avoided?

Align the notch, press firmly until both retention clips click, and do not force the module in backwards — the offset notch prevents reverse insertion.
