What exactly is FSB voltage?

Someone just asked me what FSB voltage is, and I said I really don't know.

Could someone please tell me what FSB Voltage is and what it affects?

FSB voltage is the northbridge voltage, which controls the cpu, memory and agp/pci-e parts of the motherboard. You often need to nudge this up a bit to overclock more. Increasing the voltage on this will make it run hotter, so you need to keep an eye on the temperatures.

Is there not a way of keeping the pci-e slots the same voltage?

For example, if you wanted to only overclock your CPU.

Don't confuse FSB with chipset or HTT. Very different things.

Also, chipset is not northbridge.

I haven't used a motherboard which adjusts the PCI-E slots themselves. They should always run at correct voltage. You can overclock the 'FSB' of the PCI-E slots, e.g. 100Mhz -> 105MHz can help when overclocking the system generally.
