Raider 18 HX AI A2XWJG

The Raider 18 HX AI A2XWJG is an 18-inch gaming laptop built around an Intel Core Ultra 9 285HX processor and an NVIDIA GeForce RTX 5090 laptop GPU with 24 GB GDDR7. It ships with 128 GB of DDR5 memory and 8 TB of PCIe 4.0 NVMe storage across two drives. Windows 11 Pro is pre-installed and the system is validated by an authorised MSI build-to-order partner.

Gelid GC Extreme thermal upgrade

The builder applies Gelid GC Extreme thermal interface material to both the CPU and GPU before shipment. This re-paste is intended to lower peak temperatures and reduce the likelihood of throttling during extended workloads. The laptop arrives with the latest stable BIOS and drivers installed, and each unit undergoes burn-in stress testing, benchmark verification, keyboard and touchpad checks, port validation and a full physical inspection.

Sustained load behaviour

Under continuous heavy compute or graphics demand the enhanced thermal compound helps the 24-core processor and RTX 5090 maintain higher clocks for longer periods. The 120 Hz Mini LED panel running at 3840 x 2400 resolution benefits from stable frame pacing when the cooling subsystem is not forced to throttle. Dual-channel DDR5 at 5600 MHz and the 8 TB NVMe array keep data flowing without bottlenecks during prolonged sessions.

Perguntas sobre este artigo

How can I confirm the 18" UHD+ Mini LED panel is running at its full 120 Hz refresh rate after setup?

Open the Windows display settings or the NVIDIA control panel and verify the refresh-rate dropdown shows 120 Hz for the 3840 x 2400 resolution.

What components are included in the box and which parts were added separately by the builder?

The laptop ships with the Core Black chassis, 24-core Ultra 9 285HX processor, RTX 5090 GPU with 24 GB GDDR7, 128 GB DDR5 5600 MHz memory in dual-channel configuration, and 8 TB of PCIe 4.0 NVMe storage as a 2 x 4 TB RAID array; the Gelid GC Extreme thermal compound on CPU and GPU is a builder-applied upgrade.

Which memory and storage configuration matches the listed 128 GB DDR5 and 8 TB PCIe 4.0 specification?

The system uses two 64 GB DDR5 5600 MHz modules for 128 GB total and two 4 TB M.2 PCIe 4.0 NVMe SSDs combined into an 8 TB volume.
