TridentZ RGB 16GB DDR4 kit

This 16GB dual-channel kit uses two 8GB DDR4 modules rated at 4266 MT/s with CL19 timings and 1.40V operation. It targets Intel Z490, Z390, Z370 and Z270 platforms that can run XMP 2.0 profiles. The aluminum heatspreader and exposed RGB light bar are built for high-visibility builds.

Installation notes for 288-pin DDR4

Insert both modules into the motherboard slots recommended for dual-channel operation, then enable the XMP 2.0 profile in BIOS to reach 4266 MT/s. Do not mix this kit with other memory kits; mismatched ICs often prevent the rated speed from stabilising. The 1.40V setting is within standard DDR4 limits for XMP modules.

Capacity headroom at 4266 MT/s

Sixteen gigabytes handles modern gaming, content creation and multitasking without paging on most Windows systems. Workloads that regularly exceed 16GB such as large video timelines, heavy virtualisation or massive dataset processing will need a higher-capacity kit. The CL19 19-19-19-39 timings keep latency low at the rated frequency.
