  • 64 GB dual-channel capacity for high-end multitasking
  • DDR4 4000 speed with CL18 latency for responsive performance
  • 10-layer PCB and hand-screened ICs for stable overclocking
  • Intel XMP 2.0 profile enables one-click 4000 MT/s setup
  • 76-facet crystalline heatspreader with 8-zone RGB lighting

Capacity & Audience

This 64 GB dual-channel kit delivers DDR4 4000 performance for Intel Z590 and Z490 platforms. Two 32 GB modules run at CL18 with 18-22-22-42 timings at 1.40 V via Intel XMP 2.0. It targets enthusiasts building high-end desktops who need maximum capacity and speed.

Build & Connectors

Hand-screened ICs sit on a custom 10-layer PCB beneath a 76-facet crystalline aluminium heatspreader. The 288-pin unbuffered DIMMs fit standard desktop slots and carry a patented full-length light bar that refracts 8-zone RGB across the mirrored surface. Silver finish complements premium builds.

Lighting & Software

G.SKILL software controls the fluid rainbow wave default effect and enables per-zone customisation. Motherboard RGB ecosystems can also sync the light bar through standard headers. No extra cables or controllers are required beyond the DIMM slots themselves.

Questions about this item

What DDR4 standard and speed does this kit run at, and what is the effective data rate?

The kit is rated DDR4 4000 (PC4 32000), giving an effective 4000 MT/s data rate when the XMP 2.0 profile is enabled.

What are the module dimensions and pin count for motherboard compatibility?

Each module uses the standard 288-pin DDR4 DIMM form factor with an aluminum crystalline heatspreader that adds height; verify your CPU cooler clearance before installing.

How do I enable the rated 4000 MT/s speed and CL18 timings, and what step is often missed?

Enable the Intel XMP 2.0 profile in the motherboard BIOS; the common mistake is leaving the memory at the default JEDEC speed instead of selecting the XMP profile.
