32 GB DDR5 kit with two 16 GB modules running at 6400 MT/s and CL30 latency for AMD Ryzen systems

  • 32 GB dual-channel kit for high-performance gaming
  • DDR5-6400 speed with CL30 latency for responsive workloads
  • AMD EXPO profile enables rated overclock on compatible hardware
  • Gold Trident Z5 Royal Neo design built for Ryzen 9000 series CPUs
  • 40 V operation at 30-39-39-102 timings for stable throughput

32 GB DDR5 kit for AMD Expo platforms

This 32 GB kit contains two 16 GB DDR5 modules rated at 6400 MT/s with CL30-39-39-102 timings at 1.40 V. It targets builders using AMD 600 or 800 series chipsets paired with Ryzen 9000 series processors who want high-performance memory validated through AMD Expo profiles.

Motherboard and CPU compatibility requirements

The kit uses standard 288-pin UDIMM form factor and operates as a dual-channel pair. Rated Expo speeds are reached by enabling the Expo profile in the BIOS of a compatible motherboard and CPU combination; otherwise the modules boot at default SPD speeds. Stability at the rated frequency depends on the capability of the specific motherboard and processor used.

Thermals and power in normal use

Running at 1.40 V under the rated Expo profile, the modules draw modest power typical for high-performance DDR5. The Trident Z5 Royal Neo heatspreader dissipates heat without active cooling, keeping noise at zero while maintaining stable operation during gaming or productivity workloads.

Questions about this item

Will the CL30-39-39-102 timings hold under sustained heavy workloads?

The kit is rated at CL30-39-39-102 at 1.40V via AMD EXPO; sustained stability depends on motherboard capability and CPU memory controller quality.

How much heat and power should I expect from these modules at 6400MT/s all day?

Operating at 1.40V for the rated EXPO profile, the modules draw more power and generate more heat than standard DDR5; adequate case airflow is recommended.

Which motherboard and CPU combination do I need to run this kit at 6400MT/s?

An AMD 600 or 800 series chipset motherboard with a Ryzen 9000 series CPU and EXPO support in BIOS is required to reach the rated 6400MT/s speed.
