Desktop Memory DIMM G.SKILL DDR4 16GB (2x8GB) 2666MHz PC21300, 288-pin, CL19, XMP 2.0, unbuffered, heatsink

The G.SKILL F4-2666C19D-16GIS is a 16GB DDR4 288-pin DIMM module designed to boost system responsiveness and multitasking performance in gaming and professional PCs. With a rated speed of 2666 MHz and support for Intel XMP 2.0 profiles, this memory module combines compatible hardware design and validated ICs to ensure stability across a wide range of motherboards while operating at DDR4 standard voltages (1.2–1.35V).

Advantages

Provides higher transfer rates compared with standard DDR4-2133 modules to improve frame rates and application responsiveness. Built from hand-selected ICs and validated on major motherboard brands for broad compatibility and stability. Low-voltage DDR4 operation reduces power consumption compared to DDR3, and Intel XMP 2.0 support allows easy activation of optimized performance profiles. Covered by G.SKILL's limited lifetime warranty with available technical support.

Suitable for

• Gaming desktops (FPS, RTS, MOBA, MMORPG)
• Multitasking and content creation workstations
• System upgrades where 288-pin DDR4 DIMM slots are available
• Users who want simple performance tuning via Intel XMP 2.0

How to use

Install the 288-pin DIMM module into an available DDR4 memory slot on a compatible motherboard following the motherboard manufacturer’s instructions. Ensure the system power is off and unplugged before insertion. After installation, enter the BIOS/UEFI to verify recognition of the module; enable the Intel XMP 2.0 profile if you want to apply the rated 2666 MHz timings and voltage automatically.

Recommendations

For optimal stability, install modules in matched pairs when the motherboard supports dual-channel memory and consult your motherboard manual for recommended slot population. If system instability occurs after enabling XMP, revert to default settings and verify motherboard BIOS compatibility or update the BIOS to the latest version.
