Vengeance LPX 16 GB DDR4 Kit

This Corsair Vengeance LPX kit delivers 16 GB of DDR4 memory in two 8 GB modules rated for 4000 MT/s. It targets enthusiasts who want high frequency and low latency for Intel platforms. The CL19 timing and 1.35 V voltage are set through an Intel XMP 2.0 profile for straightforward configuration.

Low-Profile Heatspreader and Eight-Layer PCB

An anodized aluminum heatspreader and an eight-layer PCB work together to move heat away from the ICs, helping stability during extended sessions. The low-profile height clears oversized CPU coolers and fits compact chassis without interfering with other components. Each IC is individually screened to provide consistent overclocking headroom.

Sustained Load Behaviour

Under continuous workloads the aluminum spreader and multi-layer PCB maintain lower operating temperatures than standard modules, reducing the chance of thermal throttling. The screened ICs and XMP 2.0 profile keep timings stable at 19-23-23-45 across long renders or gaming sessions. The 1.35 V operating voltage limits power draw while preserving the 4000 MT/s data rate.
