64GB DDR5 6400 quad-channel kit

This Corsair Dominator Titanium kit delivers 64GB across four 16GB modules running at DDR5 6400 with CL32 timings. It targets Intel 700 series platforms and 13th Gen Intel Core CPUs through an Intel XMP 3.0 profile. The black forged-aluminium heatspreader includes 11 addressable RGB LEDs per module and a swappable top bar for custom styling. Patented DHX cooling contacts both the ICs and the PCB ground plane.

Motherboard DDR5 support and XMP readiness

Verify that your motherboard supports DDR5 memory and lists the 6400 MT/s speed in its qualified vendor list for four populated slots. Confirm the BIOS exposes Intel XMP 3.0 so the 32-40-40-84 timings and 1.40V voltage apply automatically. Check that the CPU memory controller is rated for quad-channel operation at this frequency with all four DIMMs installed. Ensure the board has a 5 V addressable RGB header if you want software control of the lighting.

Four-slot layout with DHX cooling and RGB sync

The four modules occupy every DIMM slot on a standard consumer board, so plan cable routing and CPU-cooler clearance around full-height heatspreaders. DHX cooling moves heat into the case airflow path without needing a dedicated fan. The 11 LEDs per module connect to a 5 V addressable header and synchronise with major motherboard RGB ecosystems. The swappable top bar lets you change aesthetics or add 3D-printed accessories without removing the modules.
