18-inch UHD+ Mini LED display

This 18-inch laptop shows games and creative work on a UHD+ Mini LED panel at 120 Hz. The 3840 x 2400 resolution gives sharp detail for colour-critical tasks. A 12-core Ryzen AI 9 HX 370 processor and RTX 5080 graphics drive the screen. The system ships with Windows 11 Home.

Gelid GC Extreme thermal compound

HIDevolution applies Gelid GC Extreme between the CPU, GPU and their coolers to lower peak temperatures. The paste reduces throttling during sustained loads so the 12-core processor can hold higher clocks longer. Standard chassis dimensions of 15.74 x 11.41 x 0.94 inches and 6.39 lbs weight remain unchanged. The upgrade is performed before the unit leaves the builder.

96 GB DDR5 and 8 TB PCIe 4.0 storage

Two 48 GB DDR5 5600 modules provide 96 GB of dual-channel memory for large datasets and heavy multitasking. An 8 TB M.2 PCIe 4.0 x4 NVMe SSD holds operating system, games and project files with fast read and write speeds. The RTX 5080 adds 16 GB GDDR7 video memory for texture-heavy workloads. Combined capacity covers most professional and enthusiast needs.

Questions about this item

Will the 18 inch UHD+ 120Hz Mini LED panel fit in a standard 18 inch laptop sleeve?

The chassis measures 15.74 by 11.41 by .94 inches and weighs 6.39 lbs, so a sleeve sized for 18 inch laptops with at least those internal dimensions will accommodate it.

Does the 96 GB DDR5 5600 MHz memory run in dual channel?

Yes, the configuration uses two 48 GB modules installed in dual channel mode for full bandwidth.

Can the 8 TB PCIe 4.0 x4 NVMe SSD be expanded later without voiding the build-to-order warranty?

The BTO warranty covers the original upgrades; adding another M.2 drive yourself does not affect that coverage.
