18-inch WQXGA 240Hz gaming laptop

The ASUS ROG Strix G18 G815LW pairs an 18-inch 2560 x 1600 IPS-level panel at 240Hz with an Intel Core Ultra 9 275HX 24-core processor and NVIDIA GeForce RTX 5080 graphics with 16 GB GDDR7. It ships with Windows 11 Pro, 32 GB DDR5 5600 MHz memory and 16 TB of PCIe 4.0 x4 NVMe storage across two 8 TB drives. The chassis measures 15.71 x 11.73 x 0.93 to 1.26 inches and weighs 7.54 lbs in Eclipse Gray.

Thermal compound upgrade from stock paste

HIDevolution replaces the factory CPU compound with Thermal Grizzly Conductonaut and applies Gelid GC Extreme on the GPU. The liquid metal and high-conductivity paste lower peak temperatures under sustained load compared with standard thermal interface material. The improvement is most noticeable during long rendering or gaming sessions where the 5.5 GHz max turbo frequency can be held longer. Buyers who prioritise acoustic headroom or consistent boost clocks gain the most from this service.

Dual 8 TB NVMe array with DDR5 memory

The 16 TB storage pool uses two M.2 PCIe 4.0 x4 NVMe SSDs, freeing any remaining M.2 slots for future expansion while delivering fast boot and level-load speeds. The 32 GB DDR5 5600 MHz kit runs in dual channel, leaving two SO-DIMM slots open if more memory is later required. The 24-core Arrow Lake processor and RTX 5080 combination targets 2.5K high-refresh gaming, video editing and 3D workloads without needing external GPU enclosures.

Questions about this item

What are the width, depth and height range of the G815LW chassis?

The chassis measures 15.71 inches wide, 11.73 inches deep and 0.93 to 1.26 inches high.

How is the 32 GB DDR5 5600 MHz memory installed and what mistake should I avoid?

It ships as two 16 GB modules in dual-channel slots; do not add a third stick or mix speeds, or dual-channel performance will be lost.

When will the 16 TB PCIe 4.0 x4 NVMe storage need replacement?

The two 8 TB drives have no moving parts and are rated for years of typical use; replace only if SMART health drops below threshold or capacity runs out.
