Questions about this item

How do I install the RTX 3060 driver and what step is often missed?

Download the latest NVIDIA driver from the GeForce Experience app or NVIDIA website, then run the installer; the step many skip is restarting the laptop after installation to enable the 6 GB GDDR6 video memory for the 120 Hz panel.

What maintenance will the 16 GB DDR5 memory and 2 TB PCIe SSD need later?

The memory and SSD are not user-upgradable on this model; keep the vents clear of dust and update Windows 11 storage drivers periodically to maintain the 2 TB capacity and 16 GB speed.

What limit appears first during sustained gaming on the i7-12700H and RTX 3060?

The 250 nits display brightness and 120 Hz refresh rate cap visible smoothness before the 14-core processor or 6 GB GDDR6 GPU hit thermal throttling under heavy load.
