Earliest revision among the GA-Z87X-UD4H schematics here: Gigabyte revision 1.01, a PDF inside a RAR archive of about 1.34 MB. It describes the Intel Z87 LGA1150 board circuitry, including the multiphase CPU VRM, memory power, PCH and I/O. Technicians use it to read voltages expected at each stage, check signal paths and find replacement part values. Because later revisions changed details, confirm the PCB is marked 1.01 before using it on the bench.
