64GB quad-channel kit

This Corsair Vengeance LPX kit delivers 64GB of DDR4 memory across four 16GB modules rated at 2400 MT/s with CL16 timings. It targets builders who need high capacity for content creation, virtualization or heavy multitasking on desktop platforms.

Low-profile heatspreader and XMP 2.0

An anodized aluminum heatspreader and an eight-layer PCB keep thermals in check inside compact cases. XMP 2.0 support lets the firmware apply the rated speed and 16-16-16-39 timings at 1.20V with a single BIOS selection.

64GB capacity ceiling

The 64GB total handles large project files, multiple virtual machines and demanding creative workloads without paging. Systems limited to four DIMM slots cannot expand beyond this kit, so buyers who anticipate more memory should verify slot count first.

Questions about this item

How does the 1.20V operating voltage affect thermal limits during sustained heavy workloads?

The 1.20V standard voltage keeps power draw low, while the pure aluminum heatspreader and eight-layer PCB work together to dissipate heat efficiently, maintaining cooler operation during extended high-load sessions.

What noise or heat levels should I expect when running this 2400 CL16 kit continuously all day?

The modules have no moving parts, so they produce zero noise; the anodized aluminum heatspreader and custom performance PCB manage thermals passively, keeping temperatures controlled even under prolonged use.

Which motherboard feature must my system already support to activate the rated 16-16-16-39 timings automatically?

Your motherboard BIOS must support XMP 2.0; enabling the profile applies the rated DDR4 2400 speed, CL16 latency, and 1.20V voltage with a single setting change.
