Asus Z170-a memory overclocking on 6700k question

[Turboman750]

Hello,

I have a question regarding overclocking my memory on an Asus Z170-a.

I'm unable to run the memory at the rated 3200mhz xmp profile and have my system successfully boot.

I'm assuming the 4100mhz north bridge is the issue and probably needs more voltage/higher frequency.

I was wondering what the ring ratio/cache ratio voltage would be called within the Asus UEFI so I can tweak it.

If trying to run 3200 with a 6700K, will want the latest BIOS, then enable XMP, select profile 1. If no joy try an OC on the CPU, another option would be to raise the VCCIO voltage about + 0.07 (it feeds the memory controller). Generally a small OC to the CPU will suffice

Bios is already running at the latest version and I've got the cpu at 4.6ghz @ 1.28v

Have the DRAM fully seated? In proper slots (either 1-3 or 2-4 from CPU)? If yes to both try increasing the VCCIO voltage (feeds the MC) up + 0.05
