Gigabyte GA-B250M-HD3 boardview for PCB revision 1.0, provided as a TVW file inside a ZIP of about 779 KB. TVW is the Teboview layout format, opened with Tebo-ICT View or compatible boardview software. Make sure the revision printed near the PCIe slots reads 1.0. The layout helps locate components, follow nets on this B250 desktop board, find test points for VRM and standby rails and track down shorted MOSFETs or capacitors, as well as locate the SPI BIOS chip for reprogramming.
