ASUS ROG Strix G18 G815LW 18" WQXGA 240Hz

This 18-inch gaming laptop pairs an Intel Core Ultra 9 275HX processor with an NVIDIA GeForce RTX 5080 graphics card. It runs Windows 11 Home on a 2560 x 1600 IPS-level display refreshed at 240Hz. The system includes 64 GB of DDR5 5600MHz memory and 8 TB of PCIe 4.0 x4 NVMe storage.

Suits buyers needing maximum mobile graphics

The 24-core Arrow Lake CPU and 16 GB GDDR7 GPU handle heavy rendering, simulation and high-refresh gaming. The 7.54 lb chassis and 1.26 inch max thickness limit frequent travel. Users who prioritise battery life or a smaller footprint should consider lighter alternatives.

16 GB GDDR7 video memory on the RTX 5080

This VRAM capacity sets the ceiling for texture resolution, ray-tracing complexity and large-model inference at 2560 x 1600. If your workload demands more frame-buffer space, this configuration will become the bottleneck before the CPU or system memory.

Questions about this item

How can I confirm the 240Hz IPS-level panel is running at its native 2560 x 1600 resolution and full refresh rate after setup?

Open Windows Display Settings and verify the resolution reads 2560 x 1600 with the refresh rate dropdown set to 240 Hz; the NVIDIA Control Panel will also show the RTX 5080 driving the internal display at that mode.

What components are included and what must I source separately for this G815LW build?

The box contains the 18 inch laptop with the Ultra 9 275HX processor, RTX 5080 graphics with 16 GB GDDR7, 64 GB DDR5 5600 MHz memory installed as two 32 GB modules, and 8 TB of storage configured as two 4 TB PCIe 4.0 x4 NVMe SSDs; Windows 11 Home is pre-installed. No additional parts are required for operation.

Which configuration should I choose if I need the highest available memory and storage in this chassis?

This specific part number G815LW-G18.U95080-HID7 already provides the maximum listed configuration: 64 GB of dual-channel DDR5 memory and 8 TB of PCIe 4.0 NVMe storage across two 4 TB drives.
