cpu voltage, tied to speed or fsb

Probably a really stupid novice question buuuut.

Is the voltage of the cpu tied the fsb that you're running, or the actual resulting cpu speed?

My situation:

I have a q6600, 400 fsb, x8 multiplier, 3200Mhz. 1.35v

Would increasing the multiplier 9 merit a voltage increase, or is that tied more to an fsb increase.

Or both?

Thanks.
 
CPU voltage is tied to stability and what current the CPU needs to be operational. The increase of the FSB may cause an increase in voltage requirements for the CPU to remain operational as more speed requires more resources to run. CPU speed is tied to the multiplication of the FSB and the multiplier, so therefore, the increase of either one that increases CPU speed increases the voltage requirements of the CPU.
 
its never a stupid question.

increase multiplie and fsb. see what you get and run tests after.

just a question also if you increase the cpu speed don't you have the par it with your ram also?

RAM can be run with a divider to the FSB so you can increase or decrease RAM speed relative to the FSB.
 
but decreasing the fsb to your ram makes your timings off doesn't it.

and raising it gets better timings but you gotta run test and then tighten the timings.

hmm whats interesting is that ok you OC your CPU to 3.0ghz. say 400sb x9. how much would you increase the fsb of ram so where you can run your computer safely?
 
the things both killab33 and Wazooty are all independant settings. over/under clocking a cpu does not change voltage supply, it can/will change the voltage requirement at certain clocks and that is a separate adjustment you can use to achieve different clocks. the same goes for memory if you overclock it you adjust the timings for the frequency you are looking to run it at, there is nothing automatic about it. also timings != frequency in regards to memory

tbh all this is what makes overclocking an art

None of that makes sense. Decreasing your FSB:RAM ratio doesn't make your timings off. In general, running memory faster means you have to loosen the timings to maintain stability.

There is no "unsafe" FSB:RAM ratio. You can set it to whatever you want as long as your memory is capable of running at the speed you set it to.
