I have just switched from an Asus Formula VI (Z87) to an Asus Formula VII (Z97) mobo. The main reason was to get a PCIe 4x slot connected to the chipset (Z97) and not to the processor like in the Formula VI case. After assembling everthing I was really surprised to see that the 4x PCIe slot was connected to a Z97 PCIe 1x port through an ASMedia ASM1187 switch. I have checked this using hwinfo64 4.44 2300. Is this due to a wrong interpretation of the PCIe mapping by hwinfo or is there any other explaination ?
