no, tho it looks like it's got reasonable
power phases and vrm heatsink, there is no significant gain from increasing the overclock another 100mhz you can see for yourself run the
cpu-z benchmark you're probably at about as good as it will ever get. At the high overclock you reach a point of diminishing returns so it's not worth the additional stress for an insignificant increase, and the overall overclock doesn't have a huge impact on fps either. I'd stick around 4.2-3 just to stay a few steps back from the brink.
I used to run my fx 4350 overclocked at 4.9ghz and it was ok for 3 years on my sabertooth, but could only really pass the stress test at 4.8ghz but pushing the limits isn't something that can be recommended, do you see any gain in frame rates from the overclock, maybe you get 5 or 10 more frames on some titles, however I found that most of my game inventory worked just as well with or without an overclock, ultimately, there were only one or two glitches in say, elite dangerous in hyperspace that I was always trying to iron out, or maybe one or two glitches in battlefront 2 on high ultra 4k but ok at 1080p, I don't feel the overclock ever had a huge impact on anything, I wouldn't be certain by any means that it's really worth the extra load/hassle/risk.
Also on very hot days in the middle of a heatwave, when ambient temps were 38c, the highly overclocked cpu couldn't stay cool no matter what I did and tripped the thermal shutdown so I had to dial it down anyway. That was really pushing it to failure and in that instance the system was ok, but as I have a tuf sabertooth 990fx I wasn't too worried about it. A lesser board may not fare so well at the extremities of fx overclocking.
