G.SKILL Trident Z RGB 16GB (2x8GB) DDR4-4000 Desktop RAM (F4-4000C18D-16GTZRB)

G.SKILL Trident Z RGB 16GB DDR4-4000 Desktop RAM

The G.SKILL Trident Z RGB F4-4000C18D-16GTZRB is a high-performance 16GB dual-channel DDR4 memory kit designed for gaming PCs, enthusiast desktops, and performance-focused systems.

The kit includes two matched 8GB modules rated for up to 4000MT/s, with tested XMP timings of 18-22-22-42 at 1.35V. G.SKILL also equips the Trident Z RGB series with customizable RGB lighting, aluminum heatspreaders, hand-screened ICs, and a custom-engineered ten-layer PCB.

16GB Dual-Channel Kit

The kit includes 2 × 8GB DDR4 modules for a total capacity of 16GB.

Using two matched modules allows compatible motherboards to run memory in dual-channel mode, helping provide higher memory bandwidth than a single-module configuration. G.SKILL officially lists this model as a 16GB (8GBx2) Dual Channel Kit.

DDR4-4000 Performance

This Trident Z RGB kit is rated for up to 4000MT/s using its Intel XMP profile.

The higher memory speed makes it suitable for demanding workloads such as:

Gaming
Streaming
Content creation
Multitasking
High-performance desktop computing
Enthusiast PC builds

G.SKILL notes that reaching the rated 4000MT/s speed requires compatible hardware and BIOS configuration.

CL18-22-22-42 Timings

The F4-4000C18D-16GTZRB is tested at:

18-22-22-42

These are the official XMP timings specified by G.SKILL for this particular kit.

Intel XMP 2.0 Support

The memory supports Intel XMP 2.0, allowing compatible motherboards to load the tested memory speed, timings, and voltage through the BIOS.

At default BIOS settings, G.SKILL specifies an SPD speed of 2133MT/s at 1.20V. To reach the rated 4000MT/s profile, XMP must be enabled on compatible hardware.

Customizable RGB Lighting

The Trident Z RGB series features a full-width RGB LED light bar designed to provide vivid lighting across each memory module.

G.SKILL's lighting software allows additional effects and color customization, while supported motherboard software can also synchronize the memory lighting with other components.

Motherboard RGB Sync

G.SKILL lists compatibility with supported RGB ecosystems including:

ASUS Aura Sync
Gigabyte RGB Fusion
MSI Mystic Light
ASRock Polychrome Sync

Compatibility can vary depending on the motherboard model and software version.

Premium Aluminum Heatspreaders

The Trident Z RGB design uses hair-line finished aluminum heatspreaders with the signature Trident Z fin design.

The wider light diffuser at the top helps distribute RGB lighting while the metal heatspreaders help dissipate heat from the memory modules.

Hand-Screened ICs & Ten-Layer PCB

G.SKILL states that each Trident Z RGB kit uses hand-screened memory ICs selected through its testing process.

The modules also use a custom-engineered ten-layer PCB, designed to provide stable high-performance operation.

Non-ECC & Unbuffered

The F4-4000C18D-16GTZRB is:

Non-ECC
Unbuffered

This configuration is designed for mainstream gaming and enthusiast desktop PCs rather than server systems requiring ECC or registered memory.

Compatibility

Designed for compatible desktop motherboards that support:

DDR4 desktop DIMMs
Dual-channel memory
Intel XMP 2.0 or compatible memory profiles
DDR4-4000 overclocked memory speeds
16GB or greater total system memory

G.SKILL provides a QVL for this specific kit, listing tested motherboard platforms including various Intel Z370, Z390, Z490, Z590 and selected AMD X570 systems.

Important Note

The advertised 4000MT/s speed is an XMP overclocking profile.

At default BIOS settings, G.SKILL specifies the memory will boot at 2133MT/s on compatible systems. The rated 4000MT/s speed requires XMP or equivalent BIOS configuration, and actual stability depends on the CPU, motherboard, BIOS, and memory controller.

G.SKILL also recommends not mixing separate memory kits, even if they share the same model number, because each kit is tested as a matched set.

Ideal For

Gaming PCs, RGB desktop builds, enthusiast systems, high-performance workstations, streaming, content creation, multitasking, and users who want fast DDR4 memory with customizable lighting.
