The same overclocker got 5600 MHz with the A10 on air.
And your link to prove that ?
Now in fact, the A10 6800k is a pretty good value, and in the mid 4ghz range with a decent air cooler is a great budget gaming/HTPC proposition. But trying to sell it as a mid 5Ghz on air chip for actual use is ludicrously silly.
CPU @ 4.8GHz with 1086MHz iGPU and 1.475v. I choose this for 24/7.
I could get the CPU at 5GHz or above with 1.5+ voltage
iGPU could get at 1185MHz or even higher.
