Overview

The Corsair Vengeance Pro Series CMY16GX3M2A2666C12R is a 16GB dual-channel DDR3 memory kit consisting of two 8GB modules rated at 2666MHz with CAS latency of 12. This places it at the top end of DDR3 performance, designed for enthusiast and overclocking builds on platforms like Intel's Z87 and Z97 chipsets. The combination of high frequency and tight timings translates to lower effective latency, which benefits applications ranging from video editing to gaming and large dataset processing.

Running at 1.65V, the kit draws slightly more power than standard DDR3 but remains within the tolerance range for mainstream DDR3 motherboards. The Vengeance Pro series features aluminum heat spreaders with a distinctive design that helps dissipate heat during sustained operation at high frequencies. For builders maintaining or upgrading a DDR3-based system who want the best memory performance available on the platform, this kit delivers the speed and capacity to keep the system competitive for demanding workloads.

Frequently Asked Questions

This is a dual-channel kit containing two 8GB DDR3 modules, totaling 16GB.
It operates at 1.65V, which is slightly above the DDR3 standard of 1.5V. Most motherboards with XMP support handle this automatically.
It is compatible with DDR3 motherboards that support speeds up to 2666MHz or higher. Check your motherboard's qualified vendor list (QVL) for confirmed compatibility, especially at the rated speed.
CAS latency of 12 (CL12) indicates the number of clock cycles between a memory request and data delivery. At 2666MHz, CL12 is a tight timing that contributes to lower latency and better responsiveness.
Corsair Vengeance Pro DDR3 kits typically include XMP profiles so the motherboard can automatically apply the rated 2666MHz speed and timings without manual BIOS tuning.
