Vengeance LPX 64GB DDR4 Kit

This Corsair Vengeance LPX kit provides 64GB of desktop memory across four 16GB modules. It runs at DDR4 2666 with a CAS latency of 16 and operates at 1.20V. The unbuffered, non-ECC DIMMs use 288-pin connectors and feature anodized aluminum heatspreaders.

High-Capacity Overclocking Builds

The kit suits enthusiasts assembling high-performance or gaming systems that benefit from 64GB capacity and overclocking headroom. The eight-layer PCB and aluminum heatspreaders support sustained speeds. Builders needing ECC error correction or registered modules for server workloads should consider different memory.

Straightforward Desktop Installation

Modules install into standard 288-pin DDR4 slots on compatible motherboards such as AMD X399 platforms. The low-profile heatspreader design reduces clearance issues with larger CPU coolers. Ensure the BIOS is configured for the rated 16-18-18-35 timings and 1.20V voltage to avoid stability problems.

Questions about this item

Will this 64 GB kit fit in a standard ATX motherboard with four DDR4 slots?

The kit contains four 16 GB modules using the 288-pin DDR4 form factor, which matches the standard desktop DIMM layout used by most ATX boards.

What do the timing numbers 16-18-18-35 mean for everyday use?

They represent the CAS latency and subsequent delays in clock cycles; at 2666 MT/s this kit runs at CL16 with 1.20 V, a common profile for stable performance.

Does the low-profile aluminium heatspreader clear large CPU air coolers?

The Vengeance LPX design uses a reduced-height anodised aluminium spreader specifically to avoid interference with oversized tower coolers.
