Do i have to use a pencil or whatever and close the bridges or something to increase the fsb? Curently my fsb is 100 and pci is 33 ...100/33 I would like to increase it. i have a 1ghz tbird. 3dmark showed my cpumarks to be very low comparted to other users.

thanks!

No pencil trick needed for FSB overclocking. Connecting the bridges is to enable multiplier adjustments.

Taylorm: Because of the chipset's DDR FSB, you can only oc the FSB slightly. Usually 110 is as high as it goes, I have heard of lucky people that have gotten 115+ (very rare though). Gl

We AMD users are using DDR clocked motherboards. The FSB is running with the data double pumped so 100Mhz FSB gets 200Mhz performance (That's the theory) This makes FSB overclocking not as feasible as before.

Usually the maximum stable FSB for current KT133 boards is about 110-115Mhz.
