EVGA X299 DARK Owner's Manual page 22

EVGA X299 DARK (151-SX-E299)
is specifically for the CPU socket, which will typically read slightly higher than a
given CPU core. To read this temp in Fahrenheit, take the value in Celsius,
multiply by 9/5 (or 1.8) and add 32.
The display can be used to show additional temperatures, or can be configured
in tandem with all 4 digits to provide live readings for voltages or temperatures.
For example, the LEDs can be configured to read voltages, such as 1.258 or -
55C for CPU temp for when you are using LN2 extreme cooling. Detailed
configuration instructions for the Debug Indicator are provided on Page 138.
22. USB 3.0 Headers
The USB3.0 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 USB3.0 ports on the chassis. These will function the
same as the USB3 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 3.0 standard available current is 900mA @ 5V for unpowered devices. If
your USB device requires more power than this, it is recommended to attach a
powered USB Hub.
USB 3.1 Type-A (found on the I/O Hub) shares the power limit of USB 3.0 at
900mA @ 5V. Whereas USB 3.1 Type-C (also found on the IO Hub) has a
power limit of 3000mA (3A) @ 5V. USB 3.1 on the X299 Dark does not
support USB PD protocol.
23. USB 2.0 Headers
The USB2.0 header is 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 USB2.0 ports on the chassis. These will function the
same as the USB2 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.
24. VROC Header
VROC stands for Virtual RAID On CPU. The VROC header works in
conjunction with PCIe SSDs. The header is used to provide an Intel hardware
