Clocker tools:
Why is the ROG Crosshair X870E Dark Hero an excellent overclocking board? First of all, because it’s packed with tools directly on the PCB that will make your life a whole lot easier.
- The power button: turns on the motherboard.
- FlexKEY (reset): restarts the motherboard in the event of failure. The button can now be assigned to another task via the BIOS.
- Safe Boot: enables the board to be rebooted even if the parameters selected in the BIOS do not allow boot. This avoids the need to perform a CMOS Clear to reboot and thus lose your encoded parameters.
- ReTry Button: during cold tests, sometimes the OS freezes and a reset doesn’t allow the motherboard to restart: the only solution is to hold down the START button for 6 or 7 seconds. With the ReTry button, it restarts immediately.
- Switch BIOS: switches between the two bios. You can choose between an overclocking BIOS and a more stable BIOS for H24 configuration.
- Slow Mode: allows you to boot with a 16x coefficient and, once in the OS, return to the BIOS coefficient. Mainly for max screens.
- RSVD: when activated under cold conditions (-120°C), prevents cold boot bugs.
- LN2 Mode: activates LN2 profiles in the BIOS.
- Debug LED: 4 LEDs (CPU – DRAM – VGA – BOOT) to diagnose errors during board boot . If one of them remains lit, the corresponding component has a problem.
- Q-Led: displays a code corresponding to the component responsible for the boot error.
- CMOS CLR: clears BIOS parameters to return to default settings.
- ProbeIT : allows you to measure voltages with a multimeter directly on the PCB.
The PCB of this ROG Crosshair X870E Glacial :
The ROG Crosshair X870 Glacial is based on a 24-phase VCORE (110A) + 2-phase SoC (110A) + 2-phase MSIC (80A) power supply. The part in charge of the CPU is made up of 24 phases, and this model has no doubler, but the phases are placed in parallel, so there are really 12 of them. The two controllers are a Richtek RT3672JE and an ASP2205 DIGI+. The mosfets for the VCORE and the SoC are Infineon PMC41430s, and those for the MSIC are PMC41420s.
As you can see, there’s no need to worry about accommodating any processor in the Ryzen 9000 range.
