Description
The ASROCK B550M-ITX/ac motherboard is a mini ITX model with an AM4 socket, designed for compact builds with AMD Ryzen 3000 Series processors. It features two DIMM slots that support up to 64 GB of DDR4-SDRAM memory in dual channel, compatible with ECC and non-ECC unbuffered modules. For storage, it offers M.2 and SATA III interfaces, while its integrated Radeon Vega graphics, with DirectX 12 and HDCP support, covers basic visual needs without a dedicated card.
