G.SKILL Trident Z RGB Series DDR4 RAM (XMP) 32GB (2x16GB) 4000MT/s CL18-22-22-42 1.40V Desktop Computer Memory U-DIMM (F4-4000C18D-32GTZR)

Bottom line: The G.SKILL Trident Z RGB Series DDR4 RAM ($299.99 on Amazon as of 2026-10-06): 32GB as a matched 2x16GB pair for dual-channel desktop builds; main trade-off: non-ECC, so a poor fit for workstations that need error correction.

Manufacturer description

The G.SKILL Trident Z RGB Series DDR4 kit (F4-4000C18D-32GTZR) gives your desktop 32GB of memory across two 16GB modules, rated for DDR4-4000 at CL18-22-22-42 and 1.40V. That speed and timing combination suits gaming PCs and creator workstations that run large projects, many browser tabs and background apps at the same time. Out of the box, the kit boots at its JEDEC default SPD speed. To reach the rated 4000MT/s, you enable the Intel XMP profile in your BIOS (labeled XMP, DOCP or A-XMP depending on the board vendor). Enabling XMP counts as overclocking, so whether the kit holds 4000MT/s…

Frequently Asked Questions

Will the G.SKILL Trident Z RGB F4-4000C18D-32GTZR run at 4000MT/s out of the box?

No. The kit boots at its JEDEC default SPD speed at default BIOS settings. To reach DDR4-4000 CL18-22-22-42 at 1.40V, you need to enable the XMP (also called DOCP or A-XMP) profile in your BIOS, and your motherboard and CPU must be able to support that speed.

Does this RAM work with DDR5 motherboards or laptops?

No. These are 288-pin DDR4 U-DIMM desktop modules. They only fit motherboards with DDR4 desktop slots and will not work in DDR5 boards or laptop SO-DIMM slots.

Can I add this kit to the RAM I already have installed?

G.SKILL advises against mixing memory kits. Each kit is sold as a matched set designed to run together, and mixing kits can cause stability problems or system failure. If you need more than 32GB, buy a single matched kit at the capacity you want.

How do I know if my motherboard supports this kit?

Look up your motherboard in the G.SKILL memory QVL (Qualified Vendor List) or the RAM Configurator tool on the G.SKILL website. Both list the boards and hardware validated for the F4-4000C18D-32GTZR.

Is this memory ECC, and what warranty does it come with?

It is non-ECC memory built for desktop and gaming PCs. Warranty terms are not part of this listing, so check the product listing or the G.SKILL website for current coverage.
