Umm....Hope this is the right forum.
My ABIT BE-6 mobo says it will only run up to 533 Mhz FSB, but can I use a CPU w/ an 800 Mhz FSB? Is there any way to make them compatible? ANy help would be greatly appreciated!

The chip would only run @ 2/3s normal speed. If we are talking prescott here, the power requirements would kill the board. If we are talking P4c, spend the money on an IS7 mobo from Abit. That chip is worth it.

The simple answer is that you're screwed. If your mobo doesn't support it then you need a new mobo.

The more complicated answer is that <i>maybe</i>, if your board supports overclocking well enough, you <i>might</i> be able to push it to an 800MHz FSB even though it doesn't <i>officially</i> support it. Some mobos even boasted this ability for a while. (Why, I'm not sure.) So if you really want to try taking that risk (and it is a risk because it's not guaranteed to work) then check your BIOS and see if you can even set the FSB to 800MHz in there. If so, then <i>maybe</i> you can get lucky.

Otherwise, yeah, it's time for a new mobo. And if you need a new mobo to go with your new CPU then you might as well consider AMD as well as Intel.

If u dont already have the CPU, and u want to upgrade...there a simple easier/cheaper solution...

Scrap the P4...buy the DFI NF4 Lanparty MOBO and an AMD Athlon 64 3000+ Venice...

Done and done...

Or you could buy my Soyo board which supports 800fsb which i'm running a p4-m in which is only using 400fsb, and you could send me yours for free. => That would work out great for me! lol.

Well, since he'd be paying me for the board...and i'd be getting his for free...then i'd be ahead.

Then since the soyo board doesn't oc...i can't raise the fsb at all. However i can raise the fsb on his board. So...i'm getting money and a faster computer.

BE-6? You mean the Slot-1 board? Only supported 133MHz bus by overclocking.

If you meant the BE-7, it MIGHT be able to overclock to 200MHz bus (QDR800 bus), but then again, probably not.

Running an 800 bus CPU on it will underclock the thing. Do you already have a CPU?
