ROG Zephyrus S15 GX502LXS 15.6 300Hz

The ASUS ROG Zephyrus S15 GX502LXS-XS79 is a 15.6 inch FHD gaming laptop with a 300Hz IPS-level panel. It runs on an Intel Core i7-10875H processor with 8 cores and a 5.10 GHz turbo frequency. Graphics are handled by an NVIDIA GeForce RTX 2080 Super Max-Q with 8GB GDDR6 and ROG Boost. The system includes 48GB DDR4 2666MHz memory and 4TB PCIe 3.0 x4 NVMe storage across two M.2 drives. Windows 10 Pro is pre-installed.

Ideal for high-refresh competitive play

The 300Hz display and RTX 2080 Super Max-Q suit gamers who prioritize motion clarity in fast shooters. The 48GB RAM configuration supports memory-intensive workflows like virtualization or large creative projects. Buyers needing a lighter chassis or longer unplugged runtime should consider thinner ultraportables. The 100% sRGB panel serves colour-critical work, though 72% NTSC limits wide-gamut HDR authoring.

300Hz G-Sync panel drives the purchase decision

The 15.6 inch FHD screen delivers a 300Hz refresh rate with G-Sync support for tear-free motion. Combined with the RTX 2080 Super Max-Q, it enables high frame rates in demanding titles. If a lower refresh rate or non-G-Sync display is acceptable, alternative models may offer better value or battery life. The 300Hz specification is the defining factor for this configuration.

Questions about this item

What RAM slot is free for expansion after the on-board 16 GB and added 32 GB module?

The laptop ships with 16 GB soldered on-board and a 32 GB DDR4 2666MHz module installed, so no SO-DIMM slot remains open for further upgrades.

Will the 300 Hz G-Sync panel work with an older external monitor over HDMI?

Yes, the HDMI output can drive an external display at its native refresh rate while the internal 300 Hz G-Sync panel runs independently at 300 Hz.

How do I confirm the RTX 2080 Super Max-Q is hitting its ROG Boost clock?

Open GPU-Z or the ROG Gaming Center overlay during a 3D load and verify the core clock reaches the advertised boost frequency.
