24 GB DDR4 memory for creative workloads

This laptop carries 24 GB of DDR4 RAM built from an 8 GB onboard module plus a 16 GB SO-DIMM. The mixed configuration suits content creators and developers who need headroom for virtual machines or large textures. Buyers who prefer fully replaceable memory or matched dual-channel sticks should look at other models.

QHD 165 Hz display for competitive gaming

The 15.6 inch panel delivers a 2560 x 1440 resolution at a 165 Hz refresh rate. That combination gives esports players smooth motion and enough pixel density for detailed work. Users who need a built-in webcam or a higher resolution screen for professional colour grading will need a different device.

RTX 3070 8 GB GDDR6 graphics decision

The dedicated GeForce RTX 3070 laptop GPU provides 8 GB of GDDR6 video memory. That single specification determines whether the system can handle modern titles at high settings or accelerate GPU compute tasks. If the workload demands more video memory or a newer architecture, this is not the right part.

Questions about this item

What existing power supply do I need to charge the 90WHr battery?

The laptop ships with a 200W power supply; no separate charger is required for the 90WHr battery.

Can I keep using my older USB 3.0 Type-A peripherals with the two USB 3.2 Type-C Gen2 ports?

The two USB 3.2 Type-C Gen2 ports accept USB-C devices; a USB-C to USB-A adapter is needed for legacy Type-A peripherals.

How do I confirm the 165 Hz refresh rate is active on the 2560 x 1440 display?

Open Windows Display settings, select Advanced display, and verify the refresh rate dropdown shows 165 Hz.
