64 GB quad-channel kit for RGB builders

This Corsair Vengeance RGB Pro kit delivers 64 GB across four 16 GB DDR4 2666 modules rated CL16 16-18-18-35 at 1.20 V. It targets enthusiasts who want high capacity with per-module lighting control via iCUE software.

Installation ease and common pitfalls

Ten ultra-bright RGB LEDs per module light up without extra cables, and XMP 2.0 applies rated speed with one BIOS setting. The anodized aluminum spreaders add height, so verify CPU cooler clearance before seating all four sticks.

Pre-order compatibility checklist

Confirm your motherboard runs DDR4 and supports 2666 MT/s on four populated slots; the kit is validated for AMD 300 400 500 series and TRX40 plus Intel 300 400 series chipsets. Ensure the board can supply 1.20 V and that the BIOS is recent enough for XMP 2.0 activation.

Questions about this item

How can I confirm the Vengeance RGB Pro kit is running at the rated DDR4 2666 CL16 16-18-18-35 timings after installation?

Enable the XMP 2.0 profile in the motherboard BIOS, then verify the active speed and timings with CPU-Z or the board's built-in memory info screen.

What comes in the CMW64GX4M4A2666C16 package and is any extra cabling needed for the RGB lighting?

The box contains four 16 GB modules with anodized aluminum heat spreaders; no extra wires or cables are required because the 10 RGB LEDs per module draw power directly from the DIMM slot.

Which capacity version of the Vengeance RGB Pro DDR4 2666 CL16 line should I pick for a 64 GB quad-channel build?

Choose the CMW64GX4M4A2666C16 kit — it provides four matched 16 GB sticks for a total of 64 GB, optimized for the latest Intel 300, 400 series and AMD 300, 400, 500, TRX40 platforms.
