Multiplier vs FSB: Will the FSB change more?

[Sudo Chocolate]

So I am getting into overclocking and it seems that the multiplier*fsb=speed. The FSB is what  connects the chipset to CPU and other stuff so would changing the FSB affect things other than the clockspeed of the CPU?

 

Thanks,

If you change both base clock and multiplier, you'll get bigger overclock. But I'd suggest changing the multiplier only unless you're familiar with overclocking. Base Clock would be in 100MHz and your multiplier (depends on your CPU, this may vary) let's say 35MHz it means (Base clock * Multiplier) 3500MHz which means 3.5GHz, change the multiplier only (suggestion) for example crank it to 40 so it becomes 4000MHz which means 4.0GHz.

Yes, it does change the frequency of other things like PCIe lanes. I do not advise using it to overclock. Yes you are correct. Your frequency is FSB*multiplier.

It's not really called front side bus anymore it's just called base clock and changing the baseclock is really not recommended because it's the main system clock that most of the hardware uses as a reference. In most computers the baseclock is 100Mhz and the CPU uses a multiplier to determine the overall CPU clockspeed. You really shouldn't mess with baseclock because it doesn't just overclock CPU and memory it also controls things like SATA and PCI-e and if your system is not 100% rock solid stable changing the baseclock could (in extreme cases) corrupt your entire drive pool or cause your GPU or other expansion cards to become unstable even if there is nothing wrong with them.

 

Basically if you're looking to overclock your CPU just use the multiplier and keep the baseclock at default settings (100Mhz).

 

happy tweaking!

The reason I need to change the FSB is because I am tinkering with an old laptop that is not unlocked. And yes, I know that it is stupid.

If I mess stuff up it is not a big deal and I just want to see what I can do.

 

Thanks for the replys! It really clears some stuff up.
