Confused about my Ryzen OC

So I recently tried to OC my Ryzen 1600 in the following system:

 

Ryzen 1600

Noctua DH15S

MSI X370 Krait Gaming

G.Skill Flare X @3200Mhz via XMP

Fractal Design Define C with 2x Noctua 140mm for intake and 1x 120mm Noctua fan for exhaust

 

So, the CPU Cooler actually replace my previous stock fan in order to OC better. I screwed up the first try by just setting 3800Mhz at 1.35V and experienced a black screen (had to do a CMOS reset). 

After that I tried with 3600Mhz at 1.35V and I got a lower Cinebench score than I had with stock clockspeed, which I assume is due to too low voltage for the speed. This is something that I feel is weird since I can not have had THAT of a bad luck with the silicone lottery?

 

Tonight I tried another tactic, I entered 3800Mhz and left the voltage on auto in order to stress test with Prime95 (small FFT) to monitor voltage and temps. 

 

This was my results (via HWMonitor):

CPU Vcore: Min: 0.528V and Max: 1.248V

Temps: Min: 25 Degrees Celsius (76 Fahrenheit) Max: 58 Degrees Celsius (136 Fahrenheit)

 

Now, my question is:

 

Since my temps were fine after one hour of Prime95 and that my VCORE was at 1.248 maximum. Why did my computer get a black screen at a manual setting of 1.35V with the same speed? 1.35 seems to be enough due to the voltage when Auto was enabled? 

 

Or am I thinking completely wrong here?

Did you confirm it did indeed run at 3800 MHz?

Make sure to quote me or tag me when responding to me, or I might not know you replied! Examples:

Interested in computer architecture? Still in middle or high school? P.M. me!

 

I love computer hardware and feel free to ask me anything about that (or phones). I especially like SSDs. But please do not ask me anything about Networking, programming, command line stuff, or any relatively hard software stuff. I know next to nothing about that.

Yes, CPU-Z sais 3800Mhz. 

 

The Bios and Ryzen Drivers are updated.
