ROG Strix G18 18" 240Hz Ultra 9-275HX

The ASUS ROG Strix G18 G815LW is an 18-inch gaming laptop built around an Intel Core Ultra 9-275HX processor and an NVIDIA GeForce RTX 5080 GPU. It ships with Windows 11 Home, 96 GB of DDR5 memory, and a 2 TB PCIe 4.0 x4 NVMe SSD. The 2560 x 1600 WQXGA IPS-level panel runs at 240 Hz for fast-paced gaming and content creation.

24-core Arrow Lake CPU with RTX 5080 16 GB GDDR7

The 24-core (8P+16E) Arrow Lake processor reaches a 5.5 GHz max turbo frequency with 36 MB L3 cache, suiting users who run heavy multithreaded workloads alongside modern games. Buyers who need a lighter chassis, longer unplugged runtime, or a lower acquisition cost should consider smaller or less powerful alternatives.

96 GB DDR5 5600 dual-channel and 2 TB NVMe storage

The laptop arrives with 2 x 48 GB DDR5 5600 modules in dual-channel mode and a 2 TB M.2 PCIe 4.0 x4 NVMe drive installed. Applied thermal upgrades include Conductonaut on the CPU and Gelid GC Extreme on the GPU. The 15.71 x 11.73 x 0.93–1.26 inch form factor at 7.54 lbs demands a spacious bag and reliable AC power for sustained loads.

Questions about this item

Do I need to add any extra RAM sticks for the 96 GB DDR5 5600 MHz memory to run in dual channel?

No. The 96 GB is already installed as two 48 GB modules in a dual-channel configuration.

Will my existing PCIe 3.0 NVMe drive work if I install it alongside the factory 2 TB PCIe 4.0 x4 NVMe SSD?

Yes. The laptop's M.2 slot is backward compatible, so a PCIe 3.0 drive will function at its own rated speed.

How can I verify the 18 inch WQXGA panel is actually running at 240 Hz after I set up Windows 11 Home?

Open Settings > System > Display > Advanced display and confirm the refresh rate shows 240 Hz for the internal display.
