Are the new Ryzen supposed to by any better in overclock? Counterfeit CPU?

AMD CPUs | Overclockers Forums - www.overclockers.com
Hi there, I do have an Asus B350-Prime plus and I tested 4 CPU on it including that latest 2700X and for that later i'm really not impressed.

1 : R7 1700 (Could do 4Ghz max at 1.42V). It's was a defect one like most/all Ryzen sold for the first six month so AMD replaced it.

2 : R3 1200 (Could do 4Ghz at 1.4V ish, could have probably OC more but it was just for the waiting of RMA of 1.)

3 : R7 1700 from RMA of 1 (Could do 4Ghz at 1.35V, I did not try to up it more than that, 4Ghz was enough for me)

4 : R7 2700X (Can do 4.1Ghz at 1.41V, can't really do more without going at the 1.45V range and I don't like that)

So here are the questions :

a - Is the new Ryzen2 are really better? I mean, it supposed to support higher memory speed but I still have the exact same issue with my TridentZ 3200, XMP cause memory errors and don't work fine with the default 1.35V. I do have to disable XMP and set Voltage to 1.45V and timming to 14-16-16-16-32 to get it right (these are *tighter than the XMP at 16-18-18-18-38*). Same exact setting that was required on my two other R7 1700.

b - The CPU overclock look worse than my old R7 1700 I got back from RMA. As my R7 1700 was doing 4Ghz fine at 1.35V, I'm sure it can do 4.1 at similar voltage, I did not try to up it higher, maybe I should... The new 2700X really like voltage, what's is supposed to be the limit? From what I read I should not touch 1.45? for 24/24//7/7.

c - The fancy turbo stuff of the 2700X on the youtubes review where all getting like 4.3Ghz for one core and over 4Ghz (like 4.1 even) for all core. Mine do ONLY 3.95 for one core and drop to 3.7 ish for all cores.

Final question : Could I have gotten a counterfeit CPU, like a re-branded 1800X? Or it's just really low binning?. I'm considering putting the R7 1700 I got back from RMA in and selling the 2700X.
