i decided to overclock my CPU (i5-7600k) and while overclocking i realized tat my ram (corsair vengeance lpx 2x8GB 3000Mhz) is not running at the 3000Mhz but instead at 2133Mhz
and that XMP was off

I assume i turned it when i reset the bios to default and whatever i do i cant seem to get XMP to turn back on, my CPU over clock is stable and im sure that it is not the problem.

I have tried resetting bios to defult and turn xmp on with recommended settings and still doesn't post. im aware i can change voltages of the Dram in the bios but would like some advice if that is the best thing to do
