The slot lines depend on the CPU.","motherboard_form_factor":"Specifications, page 2: Mini-ITX form factor.","pcb_layers":"Specifications, page 2: 8 Layer PCB.","back_connect_design":"The layout on pages 6 and 7 shows the usual front-side power, fan and USB connectors. The board is not a back-connect design.","cpu_power_connectors":"Page 5: 1x 8 pin 12V power connector (Hi-Density Power Connector, ATX12V1) and the 24-pin ATX connector.","supplemental_pcie_power":"The connector list on page 5 has no extra slot power connector. FunkyKit's text calls the 8-pin CPU connector a PCIe power connector. The layout shows one 8-pin connector, ATX12V1.","ram_max_gb":"Page 2: max. capacity of system memory 128GB.","ram_max_speed_mts":"Page 2: DDR5 up to 8200+(OC). The manual names no CPU family. Ryzen 9000 is the newest family of the board. It refers to the Memory Support List on the maker's website.","ram_ecc":"Page 2: supports DDR5 ECC/non-ECC, un-buffered memory. The manual does not say whether ECC works with every CPU.","expansion_slots":"Page 2: 1x PCIe 5.0 x16 slot (PCIE1) from the CPU. PCIE1 runs Gen5x16 with Ryzen 9000 and 7000, Gen4x8 with Ryzen 8000 (Phoenix 1) and Gen4x4 with Ryzen 8000 (Phoenix 2). The vertical M.2 socket (Key E) for the Wi-Fi module is not listed.","m2_slots":"Page 4: M2_1 (Blazing M.2, CPU) takes type 2280 at PCIe Gen5x4, M2_1 runs Gen5x4 with Ryzen 9000 and 7000 and Gen4x4 with Ryzen 8000. M2_2 (Hyper M.2, chipset) takes type 2280 at PCIe Gen4x4. Pages 50 to 55 show an M.2 heatsink with screws on M2_1 and none on M2_2, which is on the back of the board. The manual names no SATA mode for either slot and no lane sharing. FunkyKit and PC Unboxing confirm M2_1 has a heatsink and M2_2 sits on the back, and PC Unboxing says both slots take 2280 only.","sata_port_count":"Page 4: 2x SATA3 6.0 Gb/s connectors.","rear_ports":"Pages 4 and 9: 1 USB 3.2 Gen2 Type-C (10 Gb/s, DP-alt mode DP1.4a), 2 USB 3.2 Gen2 Type-A (10 Gb/s), 1 USB 3.2 Gen1 Type-A, 4 USB 2.0, 1 HDMI 2.1 (4K 120Hz), 1 RJ-45 2.5G LAN, 1 line out jack, 1 microphone input jack and 1 optical S/PDIF out. The manual notes that the Type-C port supports a maximum speed of 40 Gb/s with selected processors. NoobFeed ties USB4 to 8000G series processors. Ryzen 9000 is the reference family, so 10 Gbps is stored. The BIOS Flashback button and the two antenna ports are not ports.","usb_headers":"Page 5: 1 USB 2.0 header for 2 ports, 1 USB 3.2 Gen1 header for 2 ports and 1 front panel Type-C USB 3.2 Gen1 header. PC Unboxing calls the front Type-C 10Gbps, which conflicts with the manual, so the manual value is stored.","fan_header_count":"Page 5 and the layout: CPU_FAN1, CHA_FAN1 and AIO_PUMP are the three 4-pin fan headers. The thermistor header is not a fan header.","argb_header_count":"Page 5: 2x addressable LED headers (3-pin ADDR_LED1 and ADDR_LED2).","rgb_header_count":"Page 5 lists only the two addressable LED headers and the layout shows no 4-pin RGB header.","ethernet_controllers":"Page 3: 2.5 Gigabit LAN, Killer E3100G. Killer chips are Intel's, so it is written Intel Killer E3100G.","wifi":"Page 3: 802.11axe Wi-Fi 6E module in a vertical M.2 (Key E) socket.","wifi_standard":"Page 3: 802.11axe Wi-Fi 6E, supports IEEE 802.11a/b/g/n/ac/ax/axe.","wifi_bands":"Page 3: dual-band 2x2 with extended 6GHz band support, and the box includes 2.4/5/6 GHz antennas. The 6 GHz band depends on country regulation.","bluetooth_version":"Page 3: supports Bluetooth 5.2.","audio_codec":"Page 3: 7.1 CH HD Audio with Content Protection (Realtek ALC1220 Audio Codec).","bios_flashback":"Page 4 and section 2.13: 1x BIOS Flashback button on the rear panel.","clear_cmos_button":"Page 8 lists a Clear CMOS jumper (CLRCMOS1).
