EVGA Z490 DARK (131-CL-E499)
- 153 -
Multifunction LED indicator
EVGA Z490 DARK board is equipped with a versatile display to allow real-time
monitoring of system status during and after the BIOS POST process. The operating
mode can be configured in the BIOS Setup in the Advanced menu, and then H/W
Monitor Configuration. The Debut Port Display setting selects the OS display mode.
There are multiple modes available:
[Temp.] CPU – displays external CPU die temperature sensor readout in real-
time. Use this mode to read negative temperatures.
[Temp.] PWM – displays VRM temperature sensor readout in real-time after
BIOS POST completion.
[Temp.] SYS – displays motherboard bay temperature sensors.
[Temp.] ATX 6P – display motherboard ATX 6P temperature sensors.
[Temp.] M.2 KEY-M(1) – displays M.2 KEY-M(1) temperature sensors.
[Temp.] M.2 KEY-M(2) – displays M.2 KEY-M(2) temperature sensors.
[Temp.] VDIMM VRM – display DIMM VRM temperature sensors.
[Temp.] PCH – displays PCH temperature sensors.
[Volt.] VCore – displays CPU VCORE after BIOS POST completion.
[Volt.] Memory – displays DIMM voltage for slots (0/1/2) after BIOS POST
completion.
[Volt.] VSA – displays System Agent CPU voltage after BIOS POST
completion.
[Volt.] VCCIO Voltage – displays I/O voltage after BIOS POST completion.
[Volt.] VCCST – displays PCH PLL voltage after BIOS POST completion.
[Volt.] VCCPLL – displays analog VCC voltage for internal clock PLL after
BIOS POST completion.
[Volt.] VCCPLL_OC – displays analog VCC voltage for internal clock PLL
after BIOS POST completion.
[Volt.] VTT – display DIMM VTT voltage after BIOS POST.
POST Code – displays only BIOS POST completion.
Turn Off - completely deactivates 80Port LED display
The Debug Port Display menu the BIOS Setup allows you to pick specific sensors to be
displayed on the 80Port.
These temperatures and voltages can also be seen in the BIOS setup window in real-
time, for a quick overview.
The recommended settings to display during overclocking are “[Temp.] CPU” and
“[Volt.] Vcore”.
