effect of overclocking on peripherals

[Jimmi]

is it possible to find out how overclocking the FSB is effecting my peripheral cards?
if so HOW??
thanx

I can be wrong but incresaing the FSB is increasing the PCI-Voltages i think. But if this is true, then how is possible to increase the FSB from 133 to 150 for example? If my theorie would be true, than the PCI cards should to be burn!, right? That means my theorie is just a bullshit :lol:

Hey, you're pretty close tersagun. First off, the raising the FSB will also raise the AGP and PCI bus speeds. Therefore, say you overclock your FSB to 133 from 100, then using a 3/1 and 3/2 divider for your PCI and AGP buses respectively, you'll get 44MHz PCI and 89MHz AGP. Now if your mobo has say, a 4/1 and 2/1 for the PCI and AGP, then you'll be running in spec. Otherwise you'll be running over, therefore possibly damamging your cards in the PCI and/or AGP slots and also your mobo.

It raises the clock rate, not the voltage, and normally doesn't hurt the card even if it pushes the card so far as to cause severe system crashes. While most cards handle 41MHz, some can only go 38MHz, and a few can handle 45MHz.

Hýmmm. So you say that i can configure the PCI and AGP bus speeds via BIOS?

Well, if your mobo has the dividers to change, then yes. Some mobo s also have the ability to lock the PCI/AGP buses at paricular speeds, so you don't run into these troubles.
