A10 CPUs cant OC that much. 1GHz OC is too much to expect, what temps are you getting? What cooler are you using and what motherboard?
Mobo: Msi FM2-A55M-E33
Ram : (2x4) 8 GB Patriot Masters Viper 3 Series 1866MHz
PSU : Corsair Builder Series CX 430 Watt 80 PLUS
Am using stock cooler right now, but from what i read is hould be able to get to 4.2 on stock cooler.
OCCT shows max temp of 45 under full load
I have raise my voltage to 1.425 as i seen here
