Archive for the ASUS H61-PLUS motherboard, a 205 KB RAR whose name does not specify the document type; files of this size in such collections are typically boardview layouts. The Intel H61 chipset serves LGA1155 Sandy Bridge and Ivy Bridge CPUs. Unpack and check the extension, then open a layout in OpenBoardView or FlexBV to find parts, check rails for shorts and follow traces from the PCH or VRM. Verify the PCB revision on the board matches the data inside.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @boardview. Enginerys does not host this file.
