Crown-Jewel RGB DDR4 Kit

This G.SKILL Trident Z Royal kit delivers 16 GB of DDR4 memory in a matched pair of 8 GB modules. It is built for enthusiasts who want high-frequency CL15 performance and a crystalline light bar with eight controllable RGB zones per stick. The gold electroplated heatspreaders use a classic tri-fin design to dissipate heat.

DDR4 4000 CL15 Practical Limits

The kit is rated for DDR4 4000 (PC4 32000) at timings of 15-16-16-36 and requires 1.50 V to reach that speed. Achieving the rated frequency and latency depends on the memory controller quality of the CPU and the motherboard's ability to train the memory at high data rates. XMP must be enabled in the firmware to apply the profile automatically.

Before Ordering Checklist

Verify that your motherboard supports DDR4 4000 via XMP and that the CPU memory controller can sustain the rated speed at 1.50 V. Confirm the board has four DIMM slots if you plan to expand beyond this dual-channel kit later. Ensure your case and CPU cooler clearance accommodate the module height with the crystalline light bar installed.

Questions about this item

Will these modules fit a motherboard with DDR4 slots and an Intel Z590, Z490 or Z390 chipset?

Yes, the kit is a dual-channel DDR4 kit validated for Intel Z590, Z490 and Z390 platforms.

Do I need to enable XMP in the BIOS to reach the rated 4000 speed and CL15 timings?

The kit runs at 4000 MT/s with timings of 15-16-16-36 at 1.50 V, which is an XMP profile; enable XMP in the BIOS to apply those settings.

Is the RGB lighting controllable through motherboard software or only the G.SKILL utility?

The modules have 8 RGB zones per stick and can be managed via the G.SKILL lighting control software for effects, profiles and per-module sync.
