9. M.2 Socket 1 Key-E 32mm
M.2 Key-E sockets are generally used for WiFi and Bluetooth cards. Key-E and
Key-M connectors are different, meaning that devices are not interchangeable
between sockets.
10. PCIe Slot x16*
PCIe x16 slots are primarily used for video cards. These full-length slots will
provide 8 or 16 lanes of bandwidth to a full-size card, and are backwards-
compatible with x8, x4, and x1-length cards.
Coffee Lake-S Socket LGA1151 processors have 16 PCIe lanes available for
routing.
11. USB 2.0 Headers
The USB 2.0 headers are used to connect additional USB interface plugs to the
motherboard; these headers are most often used to connect the motherboard to
the chassis to enable the USB 2.0 ports on the chassis. These will function the
same as the USB 2.0 ports found on the motherboard's hardwired I/O hub, but
these can be used to attach to front panel USB, auxiliary ports that mount in the
card slots, and also some devices that directly connect to the header.
USB 2.0 standard is 500mA @ 5V per port (header total is 1000mA) for
unpowered devices. If your USB device requires more power than this, it is
recommended to attach a powered USB Hub.
12. Clear CMOS Jumper Posts
The motherboard uses CMOS RAM to store set parameters. Clear CMOS by
bridging the two posts with a jumper or metallic object, such as a screwdriver.
This feature has two main uses: The first is to clear BIOS and power on before
updating the BIOS, and the second is to troubleshoot when the motherboard
fails to POST (e.g. after upgrading RAM or CPU, adding new hardware, a failed
overclock, etc.). These posts provide a much faster means of resetting CMOS
than removing the CMOS battery and discharging power to the board.
13. USB 3.1 Gen 1 Header
The USB 3.1 Gen 1 headers are used to connect additional USB interface plugs
to the motherboard; these headers are most often used to connect the
motherboard to the chassis to enable the USB 3.1 Gen 1 ports on the chassis.
These function the same as the USB 3.1 Gen 1 ports found on the
motherboard's hardwired I/O hub, but the Header can be used to attach front
