Single-Module 16 GB DDR4 Upgrade

This Corsair Vengeance LPX module delivers 16 GB of DDR4 2400 memory with CL16 timings and 1.20 V operation. The eight-layer PCB and anodised aluminium heatspreader keep temperatures low during sustained loads. It targets builders who want a straightforward capacity increase without multi-kit complexity.

Replaces Lower-Capacity DDR4 Sticks

Swapping an 8 GB or smaller DDR4 module for this 16 GB unit doubles per-slot capacity and removes the need to populate additional slots. The jump is worth it when your workload exceeds current memory headroom or when free slots are scarce. XMP 2.0 enables automatic overclocking on supported platforms.

Low-Profile 288-Pin Desktop Module

The low-profile heatspreader fits tight spaces around large CPU coolers or in compact chassis. It requires a motherboard with 288-pin DDR4 slots and standard 1.20 V support. The single-stick design leaves remaining slots open for future expansion while the screened ICs provide stable operation at rated speeds.

Questions about this item

Will the 288-pin DDR4 module fit a standard desktop DIMM slot?

Yes, the 288-pin DDR4 2400 stick fits any standard desktop DDR4 DIMM slot.

What BIOS step enables the rated CL16 16-16-16-39 timings at 1.20 V?

Enable the XMP 2.0 profile in BIOS so the board applies the rated speed, timings and voltage automatically.

Does the anodized aluminum heatspreader need any upkeep over time?

No maintenance is required; occasional dust removal with compressed air keeps the spreader effective.
