[gentoo-user] Front side bus setting

[gentoo-user] Front side bus setting

[Grant]

Does anyone know of a way to set your system's front side bus speed in
software?  My Dell motherboard and BIOS don't seem to have any
facility for it, and I've heard there is a utility in Windows that
will allow you to set it.

Isn't there a jumper or two on the circuit board that you should dis/connect 
according to the MoBo's manual to effect this?  MoBos that don't have either 
a BIOS menu choice or a jumper set up and rely on a software hack perhaps 
mean that they are not meant to run (reliably) at anything other than default 
speeds - on the other hand it may just mean that HP/Dell/etc. were providing 
something cheap & cheerful with my granny in mind and couldn't be bothered to 
fic their buggy BIOS'.  With Gentoo compiling its own software the demands 
placed on a machine are somewhat more onerous than that seen by a typical 
M$Windoze setup.

The Dell motherboard detects the CPU's FSB and sets it that way.  The
board officially supports 66/100/133.  My Celeron 700 runs at 66FSB,
but I'd like to try 100FSB so my memory will run at full speed and I
can see if the CPU can handle 1050 (10.5x multiplier).

Does anyone know of a way to set the FSB in software?

aaahhh, I don't think you want to do this...  My (perhaps limited)
understanding tells em that running a 66MHz chip at 100MHz blow it sky
high.

Although according to this web site[1] that's ok for celerons.  I'd make
sure you have some pretty decent cooling though - ie. water cooling, or
move to Alaska.

If all you want to do is run the RAM faster, what you usually have is a
FSB to RAM multiplier (can't remember what it's called - my overclocking
days are long gone :)  Which allows you to run the ram at 100 or 133...

Not me!  My best recommendation would be to buy a really good
overclocking motherboard - one with all these features in the bios.  You
should be able to get S370 mbs on ebay for cheap.
