18-inch WQXGA 240Hz gaming laptop

The ASUS ROG Strix G18 pairs an 18.0-inch WQXGA panel at 2560 x 1600 resolution with a 240Hz refresh rate. An AMD Ryzen 9 8940HX processor runs at 2.4GHz base and up to 5.3GHz boost across 16 cores and 32 threads. The NVIDIA GeForce RTX 5070 Laptop GPU supplies 8GB of GDDR7 memory alongside integrated graphics. 64GB of DDR5 memory and a 4TB PCIe SSD complete the core specification for high-frame-rate gaming and content creation.

Thermals noise and power draw

The chassis measures 15.71 x 11.57 x 0.91 inches and weighs 6.61 lbs, providing internal volume for sustained performance. ROG intelligent cooling manages heat from the 16-core CPU and RTX 5070 GPU under load while keeping acoustic output controlled during normal use. The 40Gbps USB4 ports support power delivery, allowing compatible peripherals to charge without a separate adapter. Wi-Fi 6E and Bluetooth 5.3 maintain stable wireless connectivity for cloud gaming or file transfers.

Build integration and expansion

Two USB4 Type-C ports with DisplayPort and G-SYNC support drive external monitors at high refresh rates, while an HDMI 2.1 FRL output adds a third display option. Two USB 3.2 Gen 2 Type-A ports and an RJ45 LAN jack handle legacy peripherals and wired networking. The 3.5mm combo audio jack serves headsets directly. The 4TB PCIe SSD leaves no need for secondary storage drives, and 64GB of DDR5 memory removes the requirement for immediate RAM upgrades. Windows 11 Home is pre-installed for immediate productivity.

Questions about this item

How do I install the 64GB DDR5 memory and 4TB PCIe SSD, and which step do people often get wrong?

The laptop arrives with the original seal opened by engineers who install the 64GB DDR5 and 4TB PCIe SSD before shipping. The step users miss is reseating both modules after the first thermal cycle to maintain contact pressure.

What maintenance will the RTX 5070 8GB GDDR7 graphics and cooling system need later?

Plan to repaste the CPU and GPU once a year and clean the dual-fan heatsink every six months; the 8GB GDDR7 VRAM is soldered and not user-replaceable.

What limit appears first during sustained 240Hz gaming on the 18" WQXGA panel?

The 8GB GDDR7 frame buffer fills before the Ryzen 9 8940HX hits its 5.3 GHz turbo ceiling, capping texture resolution in extended sessions.
