While you typically set the CPu to 4.4GHz, with this motherboard we were able to hit 4.5GHz and pass our benchmarks without raising temperatures too high. We believe this is because of the new power delivery system. Manually setting VCCIN at 2.1v with LLC on auto yielded a final stressed voltage between 2.0-2.1v, which is good enough. Input voltage was able to go from 1.185v to 1.20v without raising temperatures too much.

Memory overclocking was a bit surprising, we did not expect the 3600Mhz kit to work, but it did. We disabled HW P-State control, and that allowed Windows power plans to control whether we had a dynamic or static frequency. We were also able to crank mesh to x32. Now, the auto rules are a bit tight, so you will want to manually reduce System Agent offset to +0.25 from +0.5, system agent to 1.15v from 1.25v, and VCCIO to 1.05 from 1.25v, as most of those are a bit too high. You get adaptive and manual override modes for VCore, and both work well. Both our 3600MHz G.Skill kit and our 3200MHz GEIL kit worked well.
