FX-8350 vs. Core i5-3470 CPU Review

Overclocking

The FX processors have their clock multiplier unlocked, allowing you to overclock them by changing this parameter. With the FX-8350, which runs internally at 4 GHz multiplying a base clock of 200 MHz by 20, we could increase the clock multiplier to 22 and the base clock to 212 MHz, resulting in an internal clock rate of 4,664 MHz, a 16.6% increase over the CPU default clock rate.

Then we replaced the stock cooler with AMD’s liquid cooling solution, and we were able to increase the CPU multiplier to 22.5 and the base clock to 213 MHz, resulting in an internal clock rate of 4,792 MHz, a 19.8% increase over the CPU default clock rate.

In both cases, we increased the CPU voltage to 1.4000 V (from 1.348 V), the CPU-NB voltage to 1.4000 V (from 1.187 V), and the CPU VDDA voltage to 2.8000 V (from 2.490 V).

With more time and patience, you may be able to achieve even better results than we did.
