Thank you for enlightening me, I managed to overclock my rk3228a to 1.46Ghz stable and it only needed an adjustment to the clock latency. Now there is a massive improvement in performance 1.2Ghz to 1.46Ghz with the memory clocked to 2133mhz and the gpu to 700mhz and it is pretty stable. I can finally play quake 3 very smoothly. Thanks a lot
