Overview

The G.Skill Trident Z5 RGB F5-8000J4048F24GX2-TZ5RS is a high-performance DDR5 memory kit designed for enthusiasts seeking the fastest speeds available on Intel's latest platforms. Featuring two 24GB modules for a total of 48GB, this kit is rated at DDR5-8000 with timings of CL40-48-48-128 at 1.35V. The 48GB capacity provides ample headroom for demanding workloads including gaming, content creation, and multitasking without the cost premium of a full 64GB configuration.

Built around Intel XMP 3.0 technology, the kit ships with a pre-configured overclock profile that can be activated with a single BIOS toggle on supported Z890 and Z790 motherboards. The modules feature G.Skill's signature Trident Z5 heatspreader in a metallic silver finish with integrated RGB lighting that can be controlled through popular motherboard software. As a non-ECC, unbuffered DIMM kit using the standard 288-pin form factor, installation is straightforward — though users should be aware that actual achievable speeds depend on the silicon quality of both the CPU's memory controller and the motherboard, and mixing this kit with other memory modules is not supported.

Key Features

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

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 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 is validated for Intel Z890 and Z790 platforms. Check G.Skill's QVL or RAM Configurator tool for specific motherboard compatibility.
Yes. The kit boots at JEDEC default speeds out of the box. You must enable the Intel XMP 3.0 profile in your BIOS to reach the rated DDR5-8000 CL40 speed.
No. G.Skill strongly advises against mixing memory kits. The two 24GB modules are matched and tested together; mixing with other kits can cause instability or system failure.
The rated XMP profile runs at 1.35V, which is slightly above the DDR5 standard of 1.1V but typical for high-speed DDR5 overclocked kits.
The 24GB modules use a newer asymmetric memory chip configuration that can offer better overclocking headroom at ultra-high speeds like DDR5-8000 compared to traditional 32GB modules.
