Kit contents and target user

This Corsair Vengeance RGB Pro kit supplies 16 GB of DDR4 desktop memory in two 8 GB modules. It addresses builders who want a dual-channel configuration with white heat spreaders and addressable lighting.

Compatibility checks

Verify that your motherboard accepts 288-pin DDR4 modules running at 2666 MT/s and 1.20 V. The board must provide two free slots for dual-channel operation and expose an XMP 2.0 profile in the BIOS. Confirm the CPU and chipset support the rated speed without manual timing adjustments.

Ideal fit and alternatives

Suits mainstream AMD 300, 400, 500 series and TRX40 platforms plus Intel 300 and 400 series platforms where 2666 MT/s CL16 is the native or XMP speed. Builders needing ECC, higher frequencies or lower latencies should consider other kits.

Questions about this item

Will this kit fit in a standard 288-pin DDR4 motherboard slot?

Yes, the modules use the 288-pin DDR4 form factor and run at 1.20 V, so they install directly into any desktop DDR4 slot without extra cables.

Can I enable the rated 2666 MT/s speed without manual tuning?

The kit supports XMP 2.0; a single BIOS setting loads the 2666 speed with CL16-18-18-35 timings automatically.

Does the RGB lighting need a separate controller or extra wiring?

No, the 10 LEDs per module are powered through the memory slot and controlled via Corsair iCUE software alongside other compatible Corsair RGB gear.
