G.SKILL Aegis 16GB DDR4 2400 CL15

This 16GB DDR4 module runs at 2400 MT/s with CL15 15-15-15-35 timings at 1.20V. It is an unbuffered DIMM built for desktop gaming rigs and enthusiast systems. Intel XMP 2.0 support lets the BIOS apply the rated profile automatically.

Upgrade from DDR4 2133 CL15 or slower

Moving up from a 2133 MT/s kit or a lower-capacity stick adds bandwidth and reduces latency for gaming workloads. The jump is worthwhile when the motherboard and CPU memory controller can sustain 2400 MT/s without downclocking. Mixing this stick with unmatched kits will result in the system running at the lowest common speed and timing.

Simple DIMM slot installation

Align the notch, press firmly until the retention clips click, then enable XMP 2.0 in the BIOS to reach the rated 2400 MT/s CL15 profile. Common issues include leaving the profile disabled so the module stays at JEDEC defaults, or populating slots in the wrong order for dual-channel operation on the specific board.

Questions about this item

Does the 16GB DDR4 2400 CL15 module fit a standard 288-pin desktop DIMM slot?

Yes, the module uses the standard 288-pin DDR4 desktop form factor and requires a compatible motherboard DIMM slot.

How do I enable the rated 2400 speed and CL15 timing on this memory?

Enable the Intel XMP 2.0 profile in the motherboard BIOS; the common mistake is leaving the board at default JEDEC speeds instead of activating the profile.

What voltage should I expect when the kit runs at its rated specification?

The module operates at 1.20V when running at the rated DDR4 2400 CL15 15-15-15-35 specification.
