Capacity and Audience

This 64GB dual-channel kit targets Intel 600 Series and 700 Series platforms that support DDR5 6400 operation. Two 32GB modules deliver the density needed for heavy multitasking, content creation and high-refresh gaming workloads.

Build Integration

Each module carries a forged aluminium heatspreader with patented DHX cooling that draws heat from both the ICs and the PCB. The swappable top-bar design lets owners change the aesthetic or add optional cooling accessories without replacing the memory itself.

Sustained Load Behaviour

Eleven addressable RGB LEDs per module illuminate while the kit runs at 1.40V with CL32 32-40-40-84 timings under an Intel XMP 3.0 profile. The aluminium construction and DHX pathway are engineered to maintain those frequencies during extended sessions rather than throttling after a short burst.

Questions about this item

Does the 1.40 V operating voltage become a thermal limit during extended workloads?

The modules run at 1.40 V and use patented DHX cooling that draws heat from both the ICs and the PCB through the forged aluminium spreader, keeping temperatures in check during long sessions.

How loud or hot do the 11 addressable RGB LEDs and DHX cooling get when the kit runs all day?

The memory has no moving parts; the 11 LEDs add negligible heat and the DHX spreader dissipates warmth silently, so noise and thermals stay minimal under continuous use.

Which motherboard chipsets must I already have to enable the Intel XMP 3.0 profile at DDR5 6400?

The kit is validated for Intel 600 Series and Intel 700 Series platforms; a board from either series with an XMP 3.0-capable BIOS will activate the 6400 MT/s profile.
