18-inch UHD+ Mini LED workstation
The MSI Raider 18 HX AI A2XWJG pairs an 18-inch UHD+ Mini LED panel running at 120 Hz with an Intel Core Ultra 9-285HX 24-core processor and NVIDIA RTX 5090 laptop GPU with 24 GB GDDR7. Ninety-six gigabytes of DDR5 memory and four terabytes of PCIe 4.0 NVMe storage support heavy content creation and simulation workloads. Windows 11 Pro ships pre-installed.
Gelid GC Extreme thermal compound
The builder applies Gelid GC Extreme thermal interface material to the CPU and GPU to lower peak temperatures during sustained loads. Stress testing verifies stable operation before shipment. The 24-core processor reaches a maximum turbo frequency of 5.5 GHz while the discrete graphics card delivers 24 GB of video memory for large datasets.
Core Black aluminium chassis
The laptop measures 15.91 by 12.09 by 1.26 inches and weighs 7.94 pounds in a Core Black finish. Integrated LAN and WLAN provide wired and wireless connectivity. A full quality control cycle covers BIOS updates, keyboard and touchpad function, port verification and display inspection before the unit leaves the facility.

Questions about this item
How is the Gelid GC Extreme thermal compound applied to the CPU and GPU during the build-to-order process?
The builder disassembles the cooling assembly, cleans the factory paste from the Ultra 9-285HX and RTX 5090 dies, spreads a thin layer of Gelid GC Extreme on each die, then re-seats the heatsink with even pressure to avoid air pockets.
What maintenance will the DDR5 memory and PCIe 4.0 NVMe storage require over time?
The 96 GB DDR5 5600 MHz kit and dual 2 TB NVMe drives have no scheduled maintenance; keep firmware current and monitor SMART data for the SSDs, while the memory runs at standard voltage with no user-serviceable parts.
Which thermal limit appears first when the Ultra 9-285HX sustains 5.5 GHz turbo across all 24 cores?
The 24-core processor hits its junction-temperature ceiling before the power limit, causing the firmware to reduce clocks until the Gelid GC Extreme interface brings the die back into its operating window.
