G.SKILL F4-4000C18D-32GTZR TridentZ RGB 32GB (2 x 16GB) DDR4 4000 CL18 desktop RAM

32GB DDR4 4000 kit for high-performance desktops

This dual-channel kit delivers 32GB of DDR4 memory rated at 4000 MT/s with CL18 timings. It targets enthusiasts building Intel Z490, Z590 or AMD X570 platforms who need fast, responsive memory for demanding workloads and gaming. The modules use unbuffered, non-ECC DRAM and require 1.40V to reach the rated speed.

32GB capacity with 4000 MT/s headroom

The 2 x 16GB configuration provides ample space for modern games, content creation and heavy multitasking while the 4000 MT/s rating offers substantial bandwidth headroom. At default SPD settings the kit runs at standard DDR4 speeds; enabling the Intel XMP 2.0 profile is required to reach the advertised 4000 MT/s with 18-22-22-42 timings. Stability at the rated frequency depends on the specific CPU and motherboard combination used.

DDR4 4000 interface limits and XMP 2.0

DDR4 4000 (PC4 32000) operates near the top of the DDR4 frequency range, so the memory controller quality in the processor becomes the limiting factor. The kit relies on Intel XMP 2.0 to configure voltage, frequency and timings automatically; without a compatible motherboard BIOS the modules will fall back to standard JEDEC speeds. Mixing this matched kit with other memory is not supported and can cause instability or failure to boot.
