Trident Z Royal 16 GB DDR4 4000 CL15

This dual-channel kit delivers 16 GB of DDR4 memory rated at 4000 MT/s with a CL15 15-16-16-36 timing profile. It targets enthusiasts building high-performance Intel platforms who value both speed and the distinctive crystalline RGB light bar.

Installation and common issues

The unbuffered DIMMs install like standard desktop modules; seat each stick until the retention clips click. The 1.50 V operating voltage exceeds the DDR4 default, so the XMP profile must be enabled in UEFI to reach the rated 4000 MT/s speed and CL15 timings.

Compatibility checks before ordering

Verify that your motherboard appears on the vendor’s qualified-vendor list for DDR4 4000 operation and that the CPU memory controller can sustain the data rate. Confirm the silver heatspreader height clears your CPU cooler and that the power supply can deliver the required voltage for stable XMP operation.
