16 GB DDR4 2666 Desktop Module

This 288-pin DIMM delivers 16 GB of DDR4 memory rated at 2666 MT/s (PC4-21300). It is built for desktop systems that need a single high-capacity stick to fill a vacant slot or to start a new build. The module carries an Intel XMP 2.0 profile so the rated speed can be enabled with one BIOS selection.

Suited for mainstream desktops and entry servers

The stick targets builders who want 16 GB in one slot without populating every channel. Buyers who need ECC error correction, registered buffering, or speeds above 2666 MT/s should look at different modules because this unit is unbuffered non-ECC and locked to the rated frequency.

Steady throughput under long workloads

With decades of memory and server experience behind the brand, the module is validated across 200,000 platform configurations. That breadth of testing means the DRAM maintains its rated 2666 MT/s transfer rate during extended rendering, compilation, or virtualization sessions without throttling or instability.

Questions about this item

Do I need a motherboard with 288-pin DDR4 slots to install the BD16G2666MQ25?

Yes, the module uses the 288-pin DDR4 form factor, so the board must provide matching DDR4 slots.

If I add the BD16G2666MQ25 to a system that already has slower DDR4 modules, what speed will the new stick run at?

The memory controller will clock all modules to the speed of the slowest installed stick, so the BD16G2666MQ25 will operate at that lower rate.

How can I confirm the BD16G2666MQ25 is running at its rated 2666 MT/s after installation?

Enable the Intel XMP 2.0 profile in the BIOS, then check the reported memory speed in the BIOS or a system-information utility.
