Boardview for the ASUS PRIME H310M-R desktop motherboard, revision R2.0, with 1.02 also in the name, packed as a 318 KB RAR. The H310 chipset places it on Intel's LGA1151 platform. With the layout in a boardview viewer, a technician can find the CPU VRM, the SPI BIOS chip, the super I/O and the front-panel header, and trace nets during short or no-POST diagnosis. Check the revision on the PCB, because the R2.0 layout may differ from other versions.
