The B250 BTC-12P is a budget-friendly, ATX-form factor mining motherboard designed for 12-GPU cryptocurrency mining rigs. It features the Intel B250 chipset and supports 6th, 7th, and 8th generation Intel LGA 1151 CPUs, such as the Pentium G4400, i3, i5, or i7 series. It includes 2 DDR4 RAM slots supporting up to 32GB (some variants list 16GB) at speeds up to 3000 MHz, and offers 12 PCIe slots—typically 1× PCIe x16 and 11× PCIe x1—for connecting GPUs via riser cables.
The board includes VGA, DVI, or HDMI output, 4× SATA III ports, M.2 and mSATA slots for storage, and USB 2.0/3.0 headers. It is commonly used with HiveOS, though users report inconsistent compatibility due to its generic, often unbranded design with AMI Aptio BIOS. Success depends on proper BIOS settings: enable Above 4G Decoding, disable CSM, and set PCIe speed to Gen2 or Gen1 for stability.
