    Question fclk 2000 Crosshair VIII Formula

    Is there any way to get the fclk up to 2000 Mhz? The highest I can push this board is to 1900.

    No harm in trying it but 1900 is pretty much the top end for most CPUs on this that's pretty much normal

    It’s almost not worth it, reaching FCLK 2000

    So the first thing that you need is the January 2021 Bios update. After that you might be able to reach 2000 FCLK on Auto but your computer might randomly turn off, or you might have Audio issues when you are at FCLK 2000. To fix the Audio problems and reach a stable FCLK clock of 2000 you need to raise the SOC Voltage to around 1.175V and raise the PLL Voltage to at least 1.9V. The downside is that when you raise your SOC Voltage it takes away from your ability to Overclock since it will raise your temperature much higher. You’ll gain about a 100-200 point increase on Cinebench R20 if you get a 1:1 ratio though. VDDG IOD/CCD/VDDP can all be set to minimum .910V or recommend around .95. Maybe 1.0V if you cannot boot.
