How can I over clock the ram on a gigabyte z270 gaming k3? I am running an i5 7600k with ddr4 3000 corsair rgb ram. I have no problem getting the cpu to 4.2 or 4.4ghz, but the system crashes as soon as I enable XMP (all done by following gigabytes overclocking instructions, as well as using the instructions in the manual) to get it from 2133 to the 3000. I know it is possible, as I bought the ram after reading posts on how many were using it successfully with this combo. Your assistance would be greatly appreciated (then I will try building my own with g-skill trident z 3200 ram ).
