Overview

The G.Skill Trident Z5 RGB DDR5-6400 kit (F5-6400J3239G16GX2-TZ5RW) is a 32GB dual-channel memory configuration consisting of two 16GB DDR5 U-DIMM modules rated at 6400MT/s with CL32-39-39-102 timings at 1.40V. In practical terms, those specifications translate to approximately 102.4 GB/s of theoretical dual-channel bandwidth with a true access latency of around 10.0 nanoseconds — a meaningful improvement over DDR5-5200 or DDR5-5600 baseline configurations in both throughput-bound workloads like video encoding and latency-sensitive tasks like gaming. The kit ships with an Intel XMP 3.0 profile, meaning a single BIOS toggle on compatible Intel Z890, Z790, B860, or B760 motherboards brings the memory to its rated speed without manual timing or voltage configuration.

This kit targets enthusiast PC builders and gamers running Intel 13th, 14th, or Arrow Lake generation processors who want to move beyond JEDEC baseline DDR5 speeds without the instability risk of aggressive manual overclocking. The matte white dual-texture heatspreader accommodates most tower coolers without clearance issues, and the integrated RGB lighting is controllable through major motherboard software suites. At 288 pins in standard U-DIMM form factor, physical compatibility is straightforward on any DDR5 desktop platform. The key constraint to understand is that this is a matched, binned kit — the two modules are tested together at these specific timings, and mixing with other memory will likely result in the system falling back to JEDEC defaults or failing to boot. For builders who want validated DDR5-6400 performance with minimal configuration effort on Intel platforms, the Trident Z5 RGB delivers exactly that.

Key Features

* Requires overclocking/BIOS adjustments. Maximum speed and performance depends on system components, including motherboard and CPU.

G.SKILL Trident Z5 RGB Series DDR5 U-DIMM Memory Kit, Model: F5-6400J3239G16GX2-TZ5RW

Non-ECC, DDR5 U-DIMM, 288-pin, for Desktop PC & Gaming

Includes JEDEC default profile, and Intel XMP 3.0 memory overclock profile

Do not mix memory kits. Memory kits are sold in matched kits that are designed to run together as a set. Mixing memory kits will result in stability issues or system failure.

For Intel Z890, Intel Z790, Intel B860, Intel B760 platforms. Refer to G.SKILL memory QVL or RAM Configurator tool on the G.SKILL website for more details on validated motherboard and hardware.

Usage in any manner inconsistent with manufacturer specifications, warnings, designs, or recommendations will result in lower speeds, system instability, or damage to the system or its components.

Memory kits will boot at JEDEC default SPD speed at default BIOS settings with compatible hardware.

Frequently Asked Questions

This kit includes an Intel XMP 3.0 profile and is validated for Intel Z890, Z790, B860, and B760 platforms. It does not carry an AMD EXPO profile. It will physically fit any DDR5 motherboard but reaching the rated 6400MT/s speed on AMD requires manual BIOS tuning with no guaranteed stability — check G.Skill's QVL for AMD validation if needed.
DDR5-6400 delivers approximately 51.2 GB/s per channel (102.4 GB/s dual-channel), a 14% bandwidth increase over DDR5-5600. The CL32 timing at 6400MT/s yields a true latency of roughly 10.0 nanoseconds, which is comparable to or better than lower-speed kits with tighter CAS numbers — so you gain bandwidth without sacrificing latency.
Yes. Out of the box, the kit boots at the JEDEC default DDR5 speed (typically 4800MT/s). You must enter your BIOS and enable the Intel XMP 3.0 profile to reach DDR5-6400 at CL32-39-39-102 with 1.40V. This is a one-step process on supported motherboards.
G.Skill explicitly warns against mixing memory kits. These two 16GB modules are binned and tested together as a matched pair. Adding modules from a different kit — even the same model — risks instability or failure to POST because the secondary modules were not validated at these timings with this specific pair.
The kit runs at 1.40V, which is within the standard range for XMP DDR5 overclocking. DDR5 modules are generally rated to handle up to 1.435V on mainstream platforms. At 1.40V, you are well within safe daily operating parameters and should not experience accelerated degradation.
