AMD Overdrive Overclocking questions

[Whosonicus]

What does the Turbo Clock Control do, and how is it different to the normal "Clock/Voltage" page?

 

 

What is CPU VID and NB VID? Should I increase this as I increase the multiplier on the Core?

 

How would you know if the CPU has a great Power:Performance ratio? (Voltage: Multiplier)

 

 

Should I disable anything about the processor in the BIOS? (Anything that would prevent my CPU from overclocking)

Overclocking via the bios is much more reliable then overdrive, but the turo boost boosts the cores past the default frequency when only some of the cores are being used. Cpu VID is most likely the cpu voltage.

I found nothing about Overclocking in my BIOS....

For Turbo boost, should I disable this when overclocking?

Turbo clock control lets you adjust the boost states of your CPU (3.7 and 4.0GHz in its factory configuration). Hence,  you can adjust those states independently of the rest if you want. 

 

The clock/voltage page is to adjust the base  clock (3.4 by default) on which all 4 cores operate. 

 

CPU VID is the cpu voltage as requested by the cpu to operate at its base clock (the other states have their own voltages). Increase it only if your computer is unstable at the desired multiplier (run a stress test such as OCCT to find out). 

 

NB controls the North Bridge voltage,  and CPU NB controls the voltage of the IMC. Don't mess with them if you are only overclocking the CPU, especially if doing so through the multiplier. 

 

Many people would tell you to disable a number of things. In my experience,  though, the only thing that truly interfere with stable overclocks is the turbo core mode,  since it's hard ti get the relative increases in clocks and voltages right.

The power saving features are mostly harmless, despite many people suggesting to disable them as well.

Yes,  and anything related to "spread spectrum" and "APM" or something like that,  since those are power management tools that only work well when the cpu runs at stock values.
