Corsair Dominator GT DDR3-1866 TC - 6GB

Extreme Performance for Extreme Systems


Removable heatsinks allow you to change colors or add the optional extended cooling fins.


Designed for the best of the best
The average PC doesn't need Dominator GT memory. Neither do most above-average PCs, for that matter. But if you're assembling a dream system with the best components available — a truly amazing enthusiast-grade system for doing truly amazing things — Dominator GT is the right choice.

Extensive performance modeling, screening, and testing
The manufacturing process starts with DRAM chips that are tightly screened against outrageous targets for speed and latency. The assembled memory modules are then screened again and undergo testing to ensure that they'll provide stability you can count on. You'll get great specs out of the box, with generous headroom for overclocking.

XMP Memory Profile for simple, safe overclocking
Dominator GT memory supports the Intel XMP (Extreme Memory Profile) standard, and each module is individually factory-programmed with an XMP profile indicating supported timing, frequency and voltages. Just enable XMP on your compatible motherboard and you'll automatically get optimized memory overclocking without having to deal with multiple BIOS settings. Of course, if you're an experienced overclocker, or an aspiring one, you can adjust the settings to push for even higher performance.

Patented DHX+ technology with removable heatsinks
State-of-the-art cooling is essential for high-performance memory. Our DHX+ technology uses specially designed heatsinks and a custom-designed PCB that cools the front and rear of the DRAM chips as well as the printed circuit board itself.
A modular heatsink design gives you the flexibility to change the color for a custom look, or to swap them out for the optional extended cooling fins.
