Decrypted PDF schematic for board V330, with the suffix 71 most likely marking revision 7.1. The V-prefixed code resembles the MS-V numbering MSI uses for graphics card PCBs, so treat it as a video card diagram and confirm against the silkscreen. The bracketed number and Decrypt tag show that protection was removed so it opens in any PDF reader. Use it to follow VRM phases, memory and core rails, and the PCIe power input, and match the revision first.
