Trident Z5 RGB 64GB DDR5 6400 Kit

This G.SKILL Trident Z5 RGB kit provides 64GB of DDR5 memory across two 32GB modules rated at 6400 MT/s. It targets enthusiasts building on Intel 600 series or 700 series platforms who want high frequency and customisable RGB lighting in a dual-channel configuration.

Ideal for high-speed Intel DDR5 builds.

The kit is validated for Intel 600 series and 700 series platforms with XMP 3.0 profiles. Users who need ECC, registered modules, or who plan to combine this kit with other memory should look elsewhere because mixing kits is not supported.

CL32 32-39-39-102 at 1.40V decides compatibility

The decisive specification is the CL32 timing with 32-39-39-102 latencies at 1.40V. Your motherboard and CPU memory controller must support this speed and voltage combination for the XMP profile to activate correctly.

Questions about this item

Will this kit run at 6400 MT/s on a 600-series board without manual tuning?

Yes, the Intel XMP 3.0 profile sets 6400 MT/s at CL32 32-39-39-102 and 1.40 V automatically on supported 600 and 700 series platforms

Can I add another 32 GB module later to increase capacity?

Memory kits are sold in matched pairs that are tested to run together; mixing modules from different kits is not recommended and may prevent the XMP profile from working

Does the RGB lighting require a specific motherboard header or software?

The modules use standard addressable RGB and can be controlled through the motherboard vendor's lighting software when connected to a 5 V ARGB header
