Voltage Checkpoints Connector
These voltage checkpoint are used to measure the current system voltages. A multimeter (not included) will be required to check voltages. To check the voltage, please use the included voltage checkpoint cables included in the mainboard package. Attach the positive lead of the multimeter to the voltage checkpoint cable and the negative lead to the ground connector.

Point | Description |
GND (pin 6, pin 7) | Ground |
PCH_1P05 (pin 5) | PCH 1.5 voltage. The PCH voltage is the voltage supplied to |
| the Platform Controller Hub. |
VCC_DDR (pin 4) | Memory voltage. The DDR memory voltage is the voltage |
| supplied to the DDR memory modules on the mainboard. |
| Lower memory timings may require higher voltages to |
| maintain system stability. |
CPU_GFX (pin 3) | The CPU_GFX voltage is the voltage supplied to the |
| integrated graphics processor located on the CPU. |
CPU_VTT (pin 2) | CPU IO voltage (Uncore). The CPU IO voltage is the voltage |
| supplied to the Uncore on the CPU. Higher overclocks may |
| require a higher CPU IO voltage to maintain stability. |
VCCP (pin 1) | CPU core voltage. The CPU voltage is the voltage suppoied |
| to the CPU core. Higher overclocks may require higher CPU |
| core voltages to maintain stability. |
