Raider 18 HX AI A2XWJG identity

The MSI Raider 18 HX AI A2XWJG is an 18 inch gaming laptop built around an Intel Core Ultra 9 285HX processor with 24 cores and a maximum turbo frequency of 5.5 GHz. It ships with Windows 11 Pro, 64 GB of DDR5 5600 MHz memory in dual channel, and a 4 TB PCIe 4.0 NVMe SSD configured as two 2 TB modules.

UHD+ Mini LED 120Hz display focus

The 18 inch UHD+ panel runs at 3840 by 2400 resolution with a 120 Hz refresh rate and Mini LED backlighting for high contrast. Creative professionals and competitive players who need pixel density and smooth motion will benefit. Buyers who prioritise higher refresh rates at lower resolutions or who need a lighter chassis for frequent travel should consider other models.

Gelid GC Extreme thermal behaviour

HIDevolution applies Gelid GC Extreme thermal interface material on both the CPU and GPU during assembly to lower sustained temperatures. The laptop undergoes burn-in stress testing and benchmark verification before shipment to confirm stable operation under prolonged heavy loads. This preparation reduces the likelihood of thermal throttling during extended gaming or rendering sessions.

Questions about this item

Does the Intel Core Ultra 9-285HX processor require a separate purchase of DDR5 memory modules to reach the 64 GB capacity?

The laptop ships with 64 GB of DDR5 5600MHz memory installed as two 32 GB modules in dual-channel configuration, so no additional memory purchase is needed.

Can I keep using my existing PCIe 3.0 NVMe SSD alongside the factory-installed storage?

The system includes two M.2 PCIe 4.0 x4 slots populated with 2 TB NVMe SSDs each; an older PCIe 3.0 drive would need a free slot and would run at its own slower speeds.

How can I verify the Mini LED panel is delivering the 3840 x 2400 resolution at 120 Hz after setup?

Open Windows Display Settings or the NVIDIA control panel; both will show the native 3840 x 2400 resolution and a 120 Hz refresh rate when the panel is operating correctly.
