Overclocking the A8-3850 is very difficult, at least with the mothe
rboard we had available (Gigabyte GA-A75M-UD2H). This is because all clocks on the system (integrated memory controller, PCI Express lanes, SATA ports, graphics controller, memory, etc.) are tied to the CPU base clock. The default CPU base clock is 100 MHz, and the maximum we could go was only 107 MHz, making the CPU run internally at 3.1 GHz. Above that, the system would crash or would stop recognizing the hard drive. We believe that other motherboard models may allow the configuration of each separate clock, as we got reports from other editors of being able to increase the base clock up to 133 MHz, and some even above that. So, if you are into overclocking, you should carefully pick the motherboard to go with your AMD A-Series CPU.
