There are plenty of reports and reviews to show the 6300 can go as high as 5GHz, e.g the very first Google result of 'fx-6300' (techradar)
"We've even managed to push the FX-6300 over 5GHz and had it stably posting benchmark scores. I did have it booting at 5.1GHz, but we couldn't stop it falling over under the rigours of x264."
and the second result (anandtech):
"In my case the FX-4300 hit 5GHz with minimal effort, while the FX-8350 topped out at 4.8GHz (I could hit 5GHz but it wasn't stable through all of our tests). Both of these overclocks were achieved with no more than 10% additional core voltage and by simple multiplier adjustments (hooray for unlocked everything)"
It's not very helpful to blindly say other people know nothing.
