Overclocking the FSB question

[DashK]

Hello,

I have a little overclocking question regarding the FSB. What else on the motherboard runs overclocked besides the CPU and the PCI slots? Because I don't want to damage anything else on my board, because I'm going to the a P4 DDR board, because I hear they have PCI Locking/Dividers so the PCI slots can stay at normal speeds, even when the FSB is overclocked.

That way I can run a modest overclock on the FSB and not worry about my PCI cards frying, but would anything else like HDD's or CDRom drives, memory (I think memory does from what I hear) etc run overclocked?

Thanks for any help.

System RAM does.
Most good quality RAM will be able to handle it.

Thanks, do the IDE devices overclock too? Can this be dangerous, and how do you keep them at their normal speeds?

yes everything is somewhat dependent on your fsb, some motherboards allow you the option of changing fsb but giving you still a low number for pci bus. Your agp(video card) is also dependent on your fsb. Most of the time it is 2/3 for agp and 1/3 for pci(or keeping the agp as close to 66 and pci to 33). Raising either to much could hurt your components of your system. But it all depends on what motherboard you have and how much you overclock.

pci bus is on a 1/4 divider

O/C FSB O/C the entire system bus. There is not way to keep those PCI bus at normal spec of u O/C. Most modern PCI components could take a safe 37.5 Mhz (1/4 PCI divisor) & AGP card would take 75 Mhz (1/2 divisor). Based on this, u can at least O/C the FSB to 150 safe.

Depends, some motherboards allow the division to be different then oc fsb oc the pci also
on my mobo, athlon not p4, i can oc my fsb for cpu and ram but underclock my pci. I can set it to 150/150/30. or depending on division i can set it to 166/166/33 or 200/200/33.

when u overclock ur fsb so does everything else unless u have a good divider that keeps them in spec. theres only 3 separate parts to ur FSB, ur agp, memory, and pci. most likely ur video card runs on the agp, then u have your memeory, now everything else runs on the pci.. example: harddrive, cdrom, keyboard, usb, etc. if u overclock ur fsb u will overclock the other stuff as well. but if u have a good divider, u will be able to overclock ur FSB but leave ur pci at its norm.
