Schematic diagram in PDF form for the NVIDIA reference GeForce RTX 3090 built on the GA102 GPU, board PG136-A03, revision B, supplied as a RAR archive of about 2 MB. Technicians use it to follow the core and memory VRM, PCIe power inputs, the 12-pin connector circuit, GDDR6X memory lines and the power sequencing signals. Partner cards based on the PG136 reference design often share much of this circuitry, but check the PCB number and revision before relying on part values or net names.
