I have decided to reduce the CPU VCore to 1.4v applied (I will measure real VCore at the output capacitors), and see how high I can validate. On most boards, it's 5GHz.
Even with the four phase CPU VCore VRM, the Z170X-UD3 Ultra can hit 5GHz.
I was able to pull off a 4.7GHz stable overclock, which is not bad considering the very basic VRM. Anything higher will probably require a stronger voltage regulator.
Compatible Memory Overclocking Kits
Test 1: 2x4GB (8GB) Corsair Vengeance LPX 2666C16
This kit worked fine with only two sticks.
Test 2: 4x4GB (8GB) Corsair Dominator Platinum 3200MHz C16
The Dominator Platinum kit used here worked the best out of the three kits I tested.
Test 3: 2x4GB (8GB) G.Skill TridentZ 3733MHz C17
The TridentZ wasn't easy to get running, I had to make some voltage adjustments to VCCSA and VCCIO and disable fast boot so that the memory could be properly trained.
