Right or wrong, I've been one of the types that loves having my computer updated with the most current non-Beta drivers. I typically have no issues but have noticed that some Intel drivers (chipset and SATA RAID most recently) behave differently even when listed as supporting my hardware. I have a ASUS Prime Z270-A motherboard. Can someone explain Intel's numbering. For example...it seems that the third number in a driver version means something. General numbering is XX.X.X.XXXX. Most current example is that I currently have RAID driver installed as "Intel Chipset SATA RAID Controller" with version 15.7.0.1014. When I install a newer 15.7.1.1015, it works, although it lists as "Intel(R) Chipset SATA/PCIe RST Premium Controller." Computer boots but will not shut down or sleep properly. Is the "1" in the driver version something to do with consumer vs. enterprise or something? Both drivers say they support my chipset. For my education I'm curious. I've noticed similar with Intel chipset drivers. Thanks.
