Schematic for the Gigabyte GA-EP43-UD3L motherboard, revision 1.3, an Intel P43 desktop board. It comes as a PDF in a RAR of about 1.10 MB. Use it to trace the CPU VRM, memory and chipset power rails, check the power sequencing and locate the parts responsible for a short or a no-boot fault. Several revisions of this board exist with different schematics, so read the revision printed on your PCB and use this document only for 1.3.
