User Manual
FAQ
What is the screen refresh rate of this MSI GS66 Stealth laptop?
The laptop features a 15.6-inch Full HD display with a 300Hz refresh rate. This high refresh rate significantly reduces motion blur and provides smoother visuals, which is particularly beneficial for fast-paced gaming, action videos, and general desktop use where fluid cursor movement enhances the experience.
Can the RAM be upgraded on this GS66 Stealth model?
Yes, the RAM is upgradeable. It comes with 32 GB of DDR4 memory installed across two slots (2 x 16GB), and the system supports a maximum of 64 GB. The two SO-DIMM slots are currently both occupied, so upgrading would involve replacing the existing modules with higher-capacity ones to reach the 64 GB limit.
Does this laptop support Windows 11?
Yes, this laptop is eligible for a free upgrade to Windows 11. It ships with Windows 10 Pro pre-installed, and its hardware—including the 10th Gen Intel Core i7 processor and TPM support—meets Microsoft's requirements for Windows 11. Users can upgrade through Windows Update when they are ready to transition to the newer operating system.
What type of SSD does the GS66 Stealth use for storage?
It uses a 1 TB NVMe M.2 PCI Express SSD. This form factor provides much faster data transfer speeds compared to traditional SATA SSDs or hard drives, resulting in quicker boot times, faster application loading, and improved overall system responsiveness for both gaming and productivity tasks.
What ports are available on this MSI gaming laptop?
The laptop includes a comprehensive set of ports: 4 USB ports total (1 USB 3.2 Type-C and 3 USB 3.2 Gen 2 Type-A), 1 Thunderbolt 3 port, an HDMI output, a 2.5 Gigabit Ethernet jack, and audio jacks. This selection supports high-speed data transfer, external displays, wired networking, and various peripherals simultaneously.
How does the cooling system perform under heavy load?
MSI's Cooler Boost Trinity+ cooling system is designed to handle intensive workloads effectively. It uses 0.1mm thin fan blades to maximize airflow, along with multiple heat pipes to dissipate heat from the CPU and GPU. This design helps maintain stable performance during extended gaming sessions or demanding applications without excessive thermal throttling.
