Kit composition and purpose

This Corsair Vengeance LPX kit supplies 16GB of DDR4 memory across four 4GB modules rated at 2400 MT/s with CL16 timings. It targets builders who want a matched quad-channel population for high-performance or gaming workloads.

Build integration

The low-profile aluminum heatspreaders and eight-layer PCB keep module height minimal, clearing most CPU coolers and tight chassis layouts. XMP 2.0 enables automatic overclocking on compatible Intel X99 and 100 Series motherboards at the rated 1.20V.

Upgrade context

The kit replaces slower or mismatched DDR4 sticks when a full four-slot population is preferred for bandwidth. The jump is worthwhile when moving from lower-frequency modules or mixed-capacity sets that limit dual-channel or quad-channel throughput.

Questions about this item

How does the 1.20V voltage affect sustained performance?

The 1.20V standard voltage keeps power draw low during extended sessions, helping the eight-layer PCB and aluminum heatspreader manage thermals without extra cooling.

Will the aluminum heatspreader keep modules quiet under all-day load?

Yes, the pure aluminum heatspreader dissipates heat passively, so there are no fans to generate noise during continuous operation.

Does my motherboard need XMP 2.0 to run this kit at 2400?

The kit includes XMP 2.0 profiles for automatic 2400 operation; without XMP 2.0 support the modules will run at the platform's default DDR4 speed.
