Overclocking unstable

[rvmva]

Why do I get this unstable overclock.

 

 

3.6GHz turbo 3.9(STOCK)
Rome = 43.4 FPs
43.3*C
277cb
67.13fps OpenGL
1.2V

 

4.0
Rome = 44.0
55.0*C
286cb
64.23 fps OpenGL
1.432V

 

4.1
Rome = 44.3 Fps
57.4C
245cb
68.29 fps OpenGL
1.448V

 

4.2
Rome = 45.1 Fps
61.6C
226cb
67.54 fps OpenGL
1.488

 

4.3GHz
Rome = 45.2 Fps
67C
260cb
69.81 fps OpenGL
1.504V

 

4.5GHz
Rome = 43.3 Fps
69.8
200cb
76.25fps OpenGL
1.528V

Is it because:
A. I have a Cl10 ram
or B. Core voltage ​change automatically
​Or is it a whole other thing?
Please help

"CPU: A8-5600k" Well that's your problem right there. AMD CPU FailFish

I saw some overclockers that went up to 5.0 with this cpu.

I would guess thermal throttling starts in that band of testing. Your scores start falling off the cliff once you're above 1.5v

Even at 4.1 I get unstable. Even if my temps are okay

You're throttling. That board is too crap.

 

FM2 is hit and miss. Both my A10s were trash (<4.3) but both my A8s can bench 5GHz+ and run 5GHz 24/7

You're the guy that got to 5.0ghz harrynowl, right? What board did you use?

A88X Extreme6+

 

Best cpu got 5.6 as a validation, i could run cinebench at like 5.2 on 1.44v 

 

rip that cpu

I used to have an A8 3850. For awhile I was able to run it at like 3.6GHz. (BUS overclocking, locked multiplier. 2.9 stock.) For some reason the stability while overclocked got worse until even the tiniest overclock rendered the machine unusable. It was weird.
