AMD A-Series A10-7870K Kaveri Refresh APU Review

Overclocking the A10-7870K




You can overclock through AMD's Overdrive software in Windows, but I decided to use BIOS level overclocking for more consistent results. ASUS's UEFI is easy to use and there is already a built-in preset which will overclock your APU to 4.2GHz. I decided to overclock the memory with D.O.P.C, which once enabled will input the correct timings for your memory. I then went into ASUS's advanced mode and reduced the BLCK to 100MHz and set the memory divider to 24.00X and increased the CPU multiplier to 47x.





I did go into the DIGI+ Power Control menu to increase power limits, I increased most of them to their maximum just to make sure I didn't hinder power to the CPU. I set the CPU voltage to 1.48125, but you might chose a lower voltage if your cooling can't handle it. Many CPUs might not like higher voltages, but this CPU seemed to become more stable as I increased the voltage. I didn't touch the NB frequency or other voltages (DRAM voltage was automatically set by D.O.P.C), but you can tinker with those if you like. You are supposed to maintain a specific ratio between the NB and DRAM frequencies, so keep that in mind when overclocking.




This is the CPU-Z validation of the 4.7GHz/2400MHz overclock, I used this setup for the overclocking tests in the previous benchmarks.



Power Consumption


The TDP of the 7870K is 95W.




At stock, the power consumption at idle and at load are right where they should be, and overclocking the CPU doesn't prove to increase power consumption to crazy levels.
