The DDR4 modules feature black PCBs surrounded by elegant heat spreaders in this version. G.Skill opts for silver-colored coolers that are polished to a high gloss on the sides. The top edge is made of acrylic glass with a crystalline structure, highlighted by RGB lighting. The heat spreader is relatively low-profile, with an overall height of 44 millimeters, allowing the Trident Z Royal to fit under many large CPU coolers. Thanks to the heat spreaders, this 16 GB dual-channel kit remains cool at all times. As proof of high quality, G.Skill also offers an extremely long manufacturer's warranty period of 10 years. This performance DDR4 memory operates at 2,133 MHz at 1.2 volts under normal conditions. With the automatically set XMP 2.0 profiles or through manual configuration, these Trident Z Royal modules can achieve optimal performance values of up to 3,600 MHz clock speed at 1.35 volts and tested latencies of CL 18-22-22-42 when combined with a compatible motherboard.
