Trident Z5 RGB DDR5 64GB Kit

This dual-channel kit delivers 64GB of DDR5 memory across two 32GB modules. Rated at 6400 MT/s with CL32-39-39-102 timings at 1.40V, it targets enthusiasts and gamers building on modern Intel or AMD platforms. Intel XMP 3.0 support enables the rated profile with a single BIOS selection.

Aluminum Heatspreader and RGB Lighting

Each module carries a black brushed-aluminum heatspreader with customizable RGB LEDs. The spreader dissipates heat from the hand-screened ICs while the lighting integrates with motherboard RGB ecosystems. No additional software or controller is bundled; control is handled through the platform's native lighting utility.

Suited for High-Capacity DDR5 Builds

The 64GB capacity and 6400 speed suit content creation, heavy multitasking and high-refresh gaming on Intel 600/700 series or AMD 600 series chipsets. Builders needing lower capacity, tighter timings at lower voltage, or non-RGB aesthetics should evaluate alternative kits.

Questions about this item

Will the aluminum heatspreader on these DDR5 modules need any cleaning or re-pasting over time?

The black brushed-aluminum heatspreader is a passive component with no moving parts or thermal paste, so it requires no maintenance or replacement under normal use.

What timing limit appears first when the kit runs at its rated DDR5 6400 CL32 32-39-39-102 settings for long sessions?

The primary CAS latency of 32 cycles is the first timing gate the controller must meet; if voltage or temperature drift, that CL32 window is the first to show instability.

How much heat and noise does the 1.40 V dual-channel kit produce when it runs all day at 6400 MT/s?

The modules draw 1.40 V and rely on the aluminum heatspreader for silent, fanless cooling; no active noise is generated and case airflow handles the heat.
