Corsair Dominator Titanium 64GB DDR5 Kit

This quad-channel kit delivers 64GB of DDR5 memory across four 16GB modules. It runs at 6400 speed with CL32 latency and 1.40V voltage. The kit targets Intel 700 Series platforms using 13th Gen Intel Core CPUs.

Patented DHX Cooling and 1.40V Operation

Patented DHX cooling draws heat from both the ICs and the PCB through the forged aluminum heat spreader. The 1.40V operating voltage supports the 6400 CL32 profile while keeping thermals controlled. RGB lighting runs independently of the cooling path.

11 Addressable LEDs and Swappable Top Bar

Each module includes 11 individually addressable RGB LEDs for customizable illumination. A swappable top bar allows style changes or 3D-printed replacements without tools. The white heat spreader and quad-channel layout suit high-capacity Intel XMP 3.0 builds.

Questions about this item

How do I install the four 16 GB modules and enable the Intel XMP 3.0 profile?

Populate all four DIMM slots on a compatible Intel 700 series motherboard, seat each module until the retention clips click, then enter the BIOS and enable the XMP 3.0 profile to run at DDR5 6400 with CL32 timing.

What maintenance does the DHX cooling and RGB lighting require over time?

Use compressed air to clear dust from the forged aluminum heat spreader and the 11 addressable LEDs; the swappable top bar can be removed for deeper cleaning or replaced with an official accessory.

At what point does the 1.40 V operating voltage become the limiting factor during sustained loads?

The 1.40 V supply is the first constraint under prolonged heavy workloads; adequate case airflow over the DHX cooling keeps temperatures in check so the modules maintain DDR5 6400 stability.
