My system:

CPU FX8320

MoBo Asus M5A97 LE R2.0

RAM 16GB DDR3 1600mhz

HDD 1TB Seagate 

PSU Corsair 80+ Bronze 750W

GPU Gigabyte GTX770 Windforce 4GB OC Edition

Heatsink Master Cooler Vortex Plus

My Question:

The information given about this chip when I bought it was that Turbo core boosts the CPU frequency to 4.0Ghz. I have the performance option in BIOS selected and it says that my CPU frequency is at 3.8Ghz. Not that Im complaining. What I use this computer for hardly puts any strain on this beast of a processor. I have yet to see this thing use more than 30% of its total power. I'm just trying to get an understanding of how these things work. Is Turbo core something that you can turn on or off? 

I dont believe in overclocking the chip but the Turbo core is advertised as a feature by the manufacturer. My philosophy is: if you want a faster chip, pay for one. Also, I feel the chip is designed to run a certain way and screwing with it outside of manufacturer specs is playing with fire. Is Turbo corec considered overclocking the chip? Will it void the warrenty?

It is not considered overclocking and will not void the warranty, but it also rarely will be used.

The FX-8320 has a base clock of 3.5 GHz. and 4.0 GHz. Turbo mode.

The newer CPUs and APUs have a very complicated internal control that varies the operating frequency dynamically based on the processors temp and load. As long as Turbo mode is enabled in your mobo BIOS, the CPU will use up to and including the 4.0 GHz. Turbo frequency under the right conditions. It may be for a split second or for several seconds as it changes constantly based on the complex algorithm.

As far as overclocking is concerned it's understood that ANY overclocking efforts immediately void the warranty because you are operating the CPU/APU/GPU beyond the mfgs. settings. With that in mind most quality PC hardware suppliers leave a safety margin in their products to insure long life. I personally have been overclocking CPUs for 15+ years and I have never had a CPU fail - ever. I don't go crazy with the overclocking or abuse the processor with excessive voltage or inadequate cooling like some folks do. Only those who are willing to accept damaged PC hardware and immediately loss of their warranty should consider overclocking.

Your CPU running in Turbo mode is not overclocking and it has no impact on your warranty. The Vishera based FX CPUs are powerful processors and great fun.



Technical ignorance is NOT a destiny it is a choice. Do your homework so that you can make technically informed decisions and not be duped by advertising hype or mis-information stated as fact when its not.

One thing you did not mention is that Turbo Core does not boost all the cores speeds. If it did it would probably draw more power than it was designed for. As long as the total power "envelope" is maintained there is no risk overheating the processor. Intel has a similar technolgy called Turbo Boost.
