Ready-to-run mini PC

The GMKtec M6 Ultra arrives as a barebone mini PC with Windows 11 Pro pre-installed, an AMD Ryzen 5 7640HS processor, 32GB of DDR5 memory and a 1TB PCIe 3.0 SSD. It targets users who want a compact desktop for office work, media playback or light gaming without assembling parts.

32GB DDR5 and 1TB NVME headroom

Dual-channel DDR5-4800 memory runs at 32GB out of the box and can be expanded to 128GB across two SO-DIMM slots. The installed 1TB NVME drive uses a PCIe 3.0 M.2 2280 slot; a second slot supports PCIe 4.0 drives for up to 8TB per slot, giving 16TB total capacity when both are populated.

Dual fans and 120W adapter

Two internal cooling fans manage the processor’s 50W TDP, which is configurable between 45W and 60W, while the external 19V 6.32A power brick supplies up to 120W. The unit operates from -10°C to 45°C, and the fan layout keeps noise low during typical desktop loads.

Questions about this item

Will the dual 2.5GbE ports and USB4 link work with my older Gigabit switch and USB 3.0 hub without extra adapters?

Yes, both 2.5GbE RJ45 ports auto-negotiate down to 1GbE and the USB4 Type-C port is backward-compatible with USB 3.2 Gen2, USB 3.0 and USB 2.0 devices.

How can I verify the Radeon 760M is running at its 2600 MHz boost clock after I set up the M6 Ultra?

Open AMD Radeon Software or Task Manager Performance tab; the GPU clock should show 2600 MHz under 3D load and the driver will report Radeon 760M as the active adapter.

What comes in the M6 Ultra box and which expansion parts must I buy separately?

The package includes the mini PC, 120 W 19 V power adapter, VESA mount with screws, HDMI 2.0 cable and user manual; extra DDR5 SO-DIMM modules up to 128 GB total and PCIe 3.0/4.0 M.2 2280 SSDs up to 8 TB per slot are purchased separately.
