PDF schematic for the Gigabyte GA-990XA-UD3, marked R30 and stored in a 995 KB RAR archive. The token suggests a revision 3.0 board, a later version of this AM3+ model; verify against the silkscreen near the slots before use. Diagrams like these let you measure each rail at known points, follow the ATX and standby power path, test the CPU VRM and trace the SPI BIOS and Super I/O wiring. Extract with WinRAR or 7-Zip and view in any PDF reader.
