Can anyone help me with this? Every time I try to overclock my cpu in BIOS, my ddr4 3000 frequency drops to 1600 frequency in BIOS. I dont know why I cant overclock my CPU without reducing my RAM state frequency by almost half.
I understand if CPU-Z is showing 1600 on your ram it means your running 3200 because of DDR. Under normal CPU load without any overclocking my bios memory frequency shows 3000 and CPU-Z shows 1500. However when i overclock my cpu, the frequency reduces to 1600 in bios under XMP and i cant change it,and cpu-z shows 800. Is it normal for your ram frequency to reduce as you overclock your cpu?

specs:
i5 6600k
Gigabyte z170x Gaming GT
2x8gb Corsair Vengeance LPX DDR4 3000
MSI GTX 970

bios on the motherboard has been flashed to the newest update already as well.
