The ASRock B85 Pro4, built on Intel’s B85 chipset, supports 4th Gen Intel Core processors (Haswell). Designed for gamers and professionals, it features PCIe 3.0 slots, SATA 6Gb/s, USB 3.0, and CrossFireX support. The Rev 1.02 version (70-MXGQB0-A01) includes minor revisions to enhance stability and compatibility, making its Boardview file essential for accurate repairs.

Understanding Boardview Files

Unlike schematics, Boardview files provide a visual representation of a motherboard’s PCB layout, highlighting component locations, traces, and test points. Technicians rely on these files to quickly identify faulty components, trace electrical pathways, and validate connections during repairs.
