Z170 memory question

[Guest]

So I've had my computer for over a month and I want this question I have about it answered. When I built the PC to get it to boot I had to remove one stick and in the bios make the memory speed 2666mhz because for some reason it was at 1866. 1866 is not the base clock for DDR4 memory. I have it on XMP now @2666. Now this problem is for the default dram freq mind you. And for some reason I must have changed it back to 1866 or something because it was like it today. 

The dram freq doesn't matter when xmp is on right? Because I set it to 2133 which is the base for ddr4.

 

Also does anyone know how hyperx ram overclcokes itself? 

 

Thanks.

Wat?

 

Why do you need to downclock you ram?

 

DDR4 is made for much higher speeds and no Ram won't overclock itself
