ASRock Industrial IMB-A8000M AMD Ryzen 7 8840U Mini-ITX Embedded Board with ECC, Quad Display and 12-28V DC

In a closed cabinet, every watt the processor draws turns into heat the enclosure has to shed. The ASRock Industrial IMB-A8000M is the eight-core U build of the IMB-A8000 series, a Mini-ITX embedded board with a soldered AMD Ryzen 7 8840U at 15 to 30 W, ECC memory support and four DisplayPort outputs, which can ease thermal design in a smaller enclosure.

The Ryzen 7 8840U runs eight cores and 16 threads from a 3.3 GHz base clock, with AMD Radeon 780M graphics on the RDNA 3 architecture. Two SO-DIMM sockets take dual channel DDR5 5600 in ECC or non-ECC form up to 96 GB, so the IMB-A8000M can keep larger working sets in memory and use ECC where data integrity matters. Windows 11 and Linux are supported.

Four DisplayPort 1.4a outputs with DP++ on the rear panel drive four displays at up to 4K and 60 Hz. Networking is one 2.5GbE port (Realtek RTL8125BG) and one Gigabit port (Realtek RTL8111H). USB covers one USB 3.2 Gen 2 and three USB 3.2 Gen 1 at the rear plus four USB 2.0 inside. COM1 and COM2 on DB9 handle RS-232/422/485, with three RS-232 headers and a ccTalk header on the board. A PCIe x8 Gen4 slot has its own GPU card power input. Storage is an M.2 M key on PCIe Gen4 x4 for NVMe plus two SATA3 ports, an M.2 E key takes optional Wi-Fi, and an M.2 B key with SIM takes optional 4G or 5G.

Power is 12 to 28 V DC through a lockable screw-type DC jack or a four-pin wafer, with AT and ATX power-on modes for unattended starts. The IMB-A8000M is rated from -20 °C to 70 °C operating, with AMD firmware TPM, a watchdog timer and CE and FCC marks. We supply it configured and tested, with memory, NVMe storage, the OS image and any wireless modules fitted. The IMB-A8000P keeps eight cores on a 35 to 54 W Ryzen 7 8845HS, and the IMB-A8000V drops to six cores on a Ryzen 5 8640U in the same 15 to 30 W class.
