What would somebody consider extreme overclocking for the Corsair Vengeance RGB ddr5 6000 MHz 32 GB

I'm just wondering this because my Ram only allows me to overclock my 6,000 MHz Ram to 7,000 MHz it cannot do anything below that or else it will say system failed to overclock this also does it with XMP being enabled. I have tried updating bios doesn't do anything that allows me to overclock it to its recommendations
