Capacity and Platform Fit

This 32GB dual-channel kit uses DDR5 technology at 6400 MT/s with CL32 timings. It is built for Intel 600 Series and Intel 700 Series platforms that support XMP 3.0 profiles. The modules run at 1.40V and include forged aluminium heat spreaders with 11 addressable RGB LEDs each.

Ideal Buyers and Limits

Enthusiasts building on Intel 600 Series or Intel 700 Series chipsets who want high-frequency DDR5 with customizable lighting and a swappable top-bar design will match this kit. Systems that require a different memory generation, lack XMP 3.0 support, or need lower-voltage operation should consider other options.

Deciding Specification

The memory operates at DDR5 6400 with a tested latency of CL32-40-40-84 at 1.40V. If your motherboard and CPU combination cannot run this speed and timing at the stated voltage, the kit will not deliver its rated performance.

Questions about this item

What clearance does the Dominator Titanium heatspreader need above the DIMM slots?

The forged-aluminium heatspreader sits taller than standard modules, so verify your CPU cooler or case side panel leaves enough vertical room for the 11 addressable RGB LEDs and DHX cooling fins.

Which BIOS profile must be enabled to run the kit at DDR5 6400 CL32 1.40 V?

Activate the Intel XMP 3.0 profile in the motherboard BIOS; the kit will then set 6400 MT/s, 32-40-40-84 timings and 1.40 V automatically without manual entry.

Can the top bar be removed later for cleaning or a different colour?

Yes, the swappable top bar unclips from each module, letting you dust the DHX fins or fit official accessory bars or a 3D-printed replacement.
