  • Low CL30 latency with 30-39-39-102 timings keeps data flowing smoothly under load
  • Intel XMP 3.0 profile applies rated speed and timings with a single BIOS setting
  • Dual-channel 32 GB kit (2 × 16 GB) doubles bandwidth on supported platforms
  • Black brushed-aluminium heatspreader with RGB light bar manages thermals and adds visual flair

Trident Z5 RGB DDR5 6400 Kit

This 32 GB kit contains two 16 GB modules rated for DDR5 6400 with CL30 latency and a 1.40 V operating voltage. It is built for high-performance gaming and enthusiast desktop systems.

Motherboard and CPU Compatibility Check

Verify that your platform supports DDR5 memory and can run Intel XMP 3.0 profiles to reach the rated 6400 speed. The kit is validated for Intel 600 and 700 series chipsets including Z690, Z790, B660 and B760. Do not mix this matched kit with other memory modules.

Thermals and Power in Daily Use

The aluminum heatspreader dissipates heat from the DRAM ICs during sustained workloads. At the specified 1.40 V the modules draw modest power and run quietly without active cooling. RGB lighting adds negligible thermal load.

Questions about this item

Will this kit run at 6400 MT/s on an Intel Z790 motherboard without manual tuning?

Yes, the kit includes an Intel XMP 3.0 profile rated at DDR5 6400 with CL30 timings at 1.40 V. Enable XMP in the BIOS and the motherboard will apply those settings automatically.

Can I add a second identical kit to reach 64 GB on a four-slot board?

The manufacturer advises against mixing memory kits, even with the same part number. For guaranteed stability at the rated speed and timings, purchase a single 64 GB matched kit instead.

Does the 1.40 V operating voltage require extra cooling beyond the included heatspreader?

The aluminum heatspreader is designed for the specified 1.40 V XMP profile. Standard case airflow is usually sufficient; add directed airflow only if your chassis runs unusually hot.
