I always ran with a 4.1 to 4.2 OC on a offset of -0.010 stable and had no issues.
I recently changed GPU and PSU as my old PSU kind of exploded. Since I fixed everything and got it all running again I'm getting readings from both CPU-Z and Core Temp that my buss speed is dropping to 99.9 or 99.8 even and isn't stable. under load it goes even a lil above 100 sometimes on CPU-Z but always stays at 99.99 on Core temp.
I have no clue what is doing this, I redone my OC. Gave it more Voltage, went back to stock, reset cmos and nothing. Infact: If I go back to stock the buss speed is at 99.7 if not lower.
I have ran Prime 95 for several hours and nothing seems to indicate issues. Also intel burn test seems to give no issues besides the freezes every now and then under the high stress mode. (but that is normal with all cores in use)
