Ryzen 9 8945HS mini PC with 32GB DDR5

The GMKtec K11 is a barebone mini PC powered by an AMD Ryzen 9 8945HS processor with 8 cores and 16 threads. It arrives with 32GB of DDR5 5600 MT/s memory and a 1TB PCIe 4.0 M.2 2280 SSD pre-installed. Windows 11 Pro is loaded and ready to use.

Suits compact gaming and multi-display workstations

This unit fits users who want a small desktop for 4K gaming via the Radeon 780M or an external GPU through the Oculink port. It also serves creators needing four simultaneous 4K 60Hz outputs over HDMI 2.1, DisplayPort 2.1 and USB4. Builders who require more than 128GB of RAM or more than 8TB of total M.2 storage should look elsewhere.

Verify DDR5 SO-DIMM compatibility and power needs

The board provides two SO-DIMM slots supporting DDR5 5600 MT/s up to 128GB total. Two M.2 2280 PCIe 4.0 x4 slots accept additional drives up to 8TB combined. The included 19V 6.32A 120W adapter powers the system; ensure your mains supply matches 100-240V AC input.

Questions about this item

What DDR5 SO-DIMM modules do I need to add more memory to the two slots?

The board accepts DDR5 5600 MT/s SO-DIMMs in a dual-channel configuration up to 64 GB total across both slots.

Will my existing 2.5 GbE switch and Cat 5e cables work with the dual Intel i226V ports?

Yes, the two RJ45 ports run at 2.5 Gbps and are fully backward compatible with 1 GbE and 100 MbE gear.

How can I verify the Oculink port is providing a PCIe 4.0 x4 link to my eGPU enclosure?

In Device Manager check the link speed under the GPU's PCI Express root port; it should show Gen 4 x4 when the enclosure is active.
