G.Skill F5-8000J4048F24GX2-TZ5RS 48GB DDR5 8000MHz RAM

Name: G.Skill F5-8000J4048F24GX2-TZ5RS 48GB DDR5 8000MHz RAM
Brand: G.Skill
SKU: F5-8000J4048F24GX2-TZ5RS

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

G.SKILL Trident Z5 RGB Series DDR5 U-DIMM Memory Kit, Model: F5-8000J4048F24GX2-TZ5RS

48GB total capacity kit containing 2x24GB modules, rated for up to DDR5-8000 CL40-48-48-128 at 1.35V

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 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.

For memory kits with XMP and/or EXPO overclock profile, enable XMP/EXPO/DOCP/A-XMP profile in BIOS to reach up to the rated potential XMP or EXPO overclock speed of the memory kit, subject to the use of compatible hardware. Enabling XMP or EXPO is an act of overclocking and requires BIOS setting adjustments.

Reaching the rated XMP or EXPO overclock speed and system stability will depend on the compatibility and capability of the motherboard and CPU used.

Pros & Cons

👍 Pros

Extremely fast DDR5-8000 speed with CL40 latency for top-tier gaming and productivity performance.
48GB total capacity in a dual-channel kit hits a practical sweet spot between 32GB and 64GB.
Stylish metallic silver heatspreader with RGB lighting enhances build aesthetics.
Intel XMP 3.0 support enables one-click overclocking in BIOS.
Matched and factory-tested kit ensures reliable dual-channel operation.

👎 Cons

Limited to Intel Z890 and Z790 platforms, so AMD users cannot take advantage of XMP speeds.
1.35V operating voltage is higher than DDR5 baseline, generating slightly more heat under load.
Achieving the rated DDR5-8000 speed depends heavily on CPU and motherboard quality, and not all combinations will be stable.
Premium pricing compared to lower-speed DDR5 kits with similar capacity.

Frequently Asked Questions

What platforms is this memory kit compatible with?

This kit is validated for Intel Z890 and Z790 platforms. Check G.Skill's QVL or RAM Configurator tool for specific motherboard compatibility.

Do I need to enable anything in BIOS to reach DDR5-8000 speeds?

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.

Can I mix this kit with other memory modules?

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.

What voltage does this kit run at?

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.

Why 24GB modules instead of the usual 16GB or 32GB?

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.
