GIGABYTE A75-UD4H AMD APU Overclocking

Overclocking greatly varies due to what hardware is being used and who is doing the overclocking. Always remember that no two pieces of hardware will perform the same, so our results will differ from what you might be able to get. The AMD A8-3850 was cooled by an Ultra Carbon X5, this is a pretty basic CPU cooler, so we’d expect this overclock to be easily reached by anyone!

Here is a CPU-Z v1.58 screen shot of the AMD A8-3850 APU to see what we are going to be overclocking. The processor has a base clock of 100MHz with a multiplier of 29. This is a locked multiplier, so you can lower the multiplier in the BIOS, but you cannot increase it. That means for overclocking we are limited to just increasing the base clock frequency in the motherboards BIOS.

It doesn’t take much tweaking to get a solid overclock with the AMD A8-3850 APU. Other than our Bclk, the only other setting that we had to adjust within the GIGABYTE A75-UD4H system BIOS was our core voltage, once we increased the core voltage to 1.512V we were able to increase the Bclk to 135MHz for a final CPU speed of 3915MHz. This isn’t the first time that we have hit this speed, when we did our overclocking on the ASUS F1A75-V Pro we were able to hit the same results. It seems that this particular processor is limited to a Bclk of 135MHz with ~1.5V.
