16 GB DDR4 Kit for Desktop Builds

This Corsair Vengeance LPX kit provides 16 GB of DDR4 memory in two 8 GB modules. It is intended for desktop systems that use 288-pin DIMM slots and benefit from low-profile modules. The white anodized aluminum heatspreaders suit colour-coordinated builds.

DDR4 2666 Standard Limits

The modules run at DDR4 2666 (PC4 21300) with CL16 timings of 16-18-18-35 at 1.20 V. XMP 2.0 support allows the rated speed to be applied automatically on compatible motherboards. Without XMP the memory will operate at the platform default DDR4 speed.

16 GB Capacity Headroom

The 16 GB total capacity handles mainstream gaming and multitasking workloads comfortably. Demanding content-creation tasks or heavy virtualisation may exceed this amount and require additional modules or a higher-capacity kit.

Questions about this item

Will the 34 mm low-profile heatspreader clear my large CPU air cooler?

The Vengeance LPX modules measure roughly 34 mm tall, so they fit under most tower coolers without interfering with the fan clips.

Does this kit run at 2666 MT/s automatically or do I need to enable XMP 2.0 in the BIOS?

The sticks boot at JEDEC standard speeds; enabling the XMP 2.0 profile sets the rated 2666 MT/s, CL16-18-18-35 timings at 1.20 V.

Is the 16 GB (2 × 8 GB) kit compatible with Intel 100 Series motherboards?

The modules are validated for Intel 100 Series platforms and use standard 288-pin DDR4 unbuffered DIMMs for broad desktop compatibility.
