Key Features
G.SKILL Trident Z RGB Series DDR4 U-DIMM Memory Kit, Model: F4-4000C18D-16GTZRB
16GB total capacity kit containing 2x8GB modules, rated for up to DDR4-4000 CL18-22-22-42 at 1.35V
Non-ECC, DDR4 U-DIMM, 288-pin, for Desktop PC & Gaming
Includes JEDEC default profile, and Intel XMP 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.
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 overclock profile, enable XMP/DOCP/A-XMP profile in BIOS to reach up to the rated potential XMP overclock speed of the memory kit, subject to the use of compatible hardware. Enabling XMP is an act of overclocking and requires BIOS setting adjustments.
Reaching the rated XMP overclock speed and system stability will depend on the compatibility and capability of the motherboard and CPU used.
