1) As said the memory isn't overclocked when running XMP. It's just running at the OPTIMAL speed and timings for that memory.

2) The CPU at 4.5GHz is great. I'm sure others have done a bit better but due to rapidly diminishing returns you really don't want to push the limit. STABILITY is most important.

Other:
The CPU actually has a Max Turbo of 3.9GHz so it's not technically running at 4.5 instead of 3.5GHz. Turbo by default usually scales down though so when using all four cores normally you might only get 3.6GHz. You can actually MANUALLY change those values as well, and Skylake may not work exactly that way but I suspect it does.

So when running a game like Starcraft 2 which is very CPU demanding at times (but only on two cores)...

4.5ghz at 1.346v is not bad but you can probably get away with less voltage if you do it manually. Also what max temps were you seeing? Did you stress it out at all? I personally have 0 faith is any auto overclocking of any sort. XMP is about as auto as Ill get.

So when running a game like Starcraft 2 which is very CPU demanding at times (but only on two cores) you're probably getting about 3.8GHz with the default Turbo but 4.5GHz with your manual overclock.

Summary:
STABILITY is the most important thing. There's really not much more performance to be gained over your current overclock, and of course for gaming or other tasks there's usually a bottleneck elsewhere.
