PDF schematic for the Gigabyte GA-8I945GMF-RH-E motherboard, a larger document of about 7.3 MB. The 945 in the model name refers to the Intel 945 chipset family used with LGA775 processors. Use it to trace the VCore regulator, the memory and chipset supplies, and the power-on sequence, and to identify parts around the BIOS chip. The name gives no revision, so compare the board layout with these drawings and check the PCB marking before trusting component values.
