Trident Z5 Neo 32GB DDR5 6400 Kit

This 32GB dual-channel kit uses two 16GB DDR5 modules rated at 6400 MT/s with CL32 timings and 1.40V operation. It targets AMD Ryzen 7000 series platforms through AMD EXPO profiles. The black heat spreader and RGB light bar suit enthusiast gaming builds.

Optimised for AMD EXPO Ryzen systems

Builders running Ryzen 7000 or later CPUs on EXPO-ready motherboards will gain the rated speed without manual tuning. Systems on other platforms or mixed with different kits may not reach the advertised timings and should consider alternative memory.

Dual-channel DDR5 for AM5 motherboards

The 288-pin modules install in paired slots to enable dual-channel bandwidth, freeing the remaining slots for future expansion. AMD EXPO handles frequency and voltage automatically, reducing BIOS configuration time while the RGB lighting integrates with common motherboard control software.

Questions about this item

What motherboard slot and chipset do I need to run this DDR5 6400 kit at its rated speed?

You need a motherboard with DDR5 288-pin slots and an AMD Ryzen 7000 series processor to enable the EXPO profile for 6400 MT/s operation.

Can I add these two 16GB modules to my existing DDR5 memory without issues?

G.SKILL advises against mixing kits; this matched dual-channel kit is validated to run together at CL32 32-39-39-76 1.40V, and adding other modules may prevent stable operation.

How do I confirm the memory is running at 6400 MT/s with the correct timings after I build the system?

Enter the BIOS and verify the EXPO profile is active showing 6400 MT/s, CL32, 32-39-39-76 timings and 1.40V, or check the same values in CPU-Z once the OS loads.
