I have definitely been wondering about my chip getting to 4 GHz, so I did some more testing.
I finally was able to pass 10 runs of intel burn test (standard load) @ 4 GHz with 1.31875 Vcore and 1.22 IMC. My temp reaches 76*C. My CPU surely hits a wall at 3.8 GHz since that runs at even 1.25 Vcore. I guess that's not terrible, right? My CPU Cooler seems to be my bottleneck because those temps are too high for me. I want to try and keep it below 70*C during max load on burn test.
