Circuit schematic for the Gigabyte GA-990FXA-UD3 desktop motherboard, marked as revision R10 in the name, packed as a PDF inside a RAR archive of about 1006 KB. Gigabyte released several PCB revisions of this AMD 990FX board, and component placement and power circuitry can differ between them, so confirm the revision silkscreened on the PCB before following any page. Use it to trace VRM rails, standby power, clock and reset signals, and to find the right parts when diagnosing a no-power or short condition. Any PDF reader opens it after extraction.
