G.SKILL F5-8400C4052G24GX2-TZ5CK 48GB DDR5 desktop RAM

Trident Z5 CK 48GB DDR5 kit

This Trident Z5 CK kit delivers 48GB of DDR5 memory in a dual-channel pair of 24GB modules rated at 8400 MT/s with CL40-52-52-134 timings. A built-in clock driver chip strengthens the clock signal for stable high-frequency operation. The kit targets Intel Core Ultra 200 K-series processors on Z890 motherboards and activates its profile through Intel XMP 3.0.

Thermals and power at 1.40V

The glossy piano-black finned heatspreader dissipates heat generated by the 1.40V operating voltage during sustained high-speed workloads. No LEDs are present so the modules add no extra lighting power draw. The CKD component helps maintain signal integrity without increasing module temperature beyond what the spreader handles in typical enthusiast use.

Build and daily installation

Each 288-pin CUDIMM carries a CKD chip that improves clock quality at 8400 MT/s, a feature that only functions on platforms with CU-DIMM support. The classic Trident Z5 fin design fits standard DIMM slots while the black finish matches most motherboard aesthetics. Dual-channel population is straightforward on compatible Intel 800-series chipset boards.
