Small 149 KB RAR archive holding a PDF schematic for the Gigabyte GA-990XA-UD3, with 3.1 in the name, which likely marks the board revision. The compact size may mean fewer pages than the other revisions, so check the contents after extracting. Use it to follow power rails, VRM circuitry and signal paths and to locate components when hunting a short or missing voltage. Compare the revision silkscreened on your board before relying on these pages, then open the PDF in any standard reader.
