Compact barebone for custom builds

The minisforum UM870 Slim arrives as a barebone mini PC with an AMD Ryzen 7 8745H processor already installed. Eight cores and sixteen threads reach a 4.9 GHz boost clock, while integrated Radeon 780M graphics handle display output. The silver chassis targets builders who want to choose their own DDR5 memory, storage and operating system.

Two SODIMM slots and PCIe 4.0 storage

Dual-channel DDR5-5600MHz SODIMM slots accept up to 64 GB total, with each slot supporting 32 GB modules. A PCIe 4.0 x4 M.2 slot provides room for a primary SSD, and a second PCIe 4.0 slot is available for extra capacity. Video outputs comprise HDMI 2.1, DisplayPort and USB4, each capable of 8K at 60 Hz for three independent screens. Wired networking uses a 2.5G RJ45 port, while Wi-Fi 6E and Bluetooth 5.3 handle wireless duties.

Sustained output in a small enclosure

The 8745H processor maintains its 4.9 GHz boost within the slim thermal envelope, allowing extended compile sessions or rendering jobs without the sharp throttling seen in shorter bursts. Radeon 780M graphics deliver steady frame rates during long gaming or compute workloads rather than peaking briefly. Builders who need discrete GPU performance or more than two memory channels should look elsewhere.

Perguntas sobre este artigo

How much DDR5-5600 memory can the UM870 Slim accept before the limit is reached?

The board provides two SODIMM slots with dual-channel support and a maximum capacity of 64 GB using DDR5-5600 modules.

What are the thermal and acoustic characteristics when the Ryzen 7 8745H runs at 4.9 GHz all day?

The compact chassis relies on an internal fan to cool the 8-core processor and Radeon 780M graphics; sustained boost clocks will raise both surface temperature and fan speed.

Which storage and memory parts must I supply to make this barebone operational?

You need to add DDR5-5600 SODIMM modules (up to 32 GB per slot) and at least one PCIe 4.0 M.2 SSD; the system ships without RAM, storage or an operating system.
