CPU Clock Mutlipler in BIOS?

[Guest]

Archived from groups: alt.comp.periphs.mainboard.shuttle (More info?)

Hi everyone,

I have an SS51G v2.0 loaded with the latest FS51SB0l BIOS. The problem
is that I have a 2.8GHz P4 CPU but when it boots up, it only boots up
at 1.4GHz (100 x 14). Where in BIOS do I set it to run at 2.8GHz? I
have noticed that others have a multiplier of 18 so why is mine only
14?

Any help is appreciated.
Thanks.

Check your manual. You're running at the wrong memory bus speed. If the
multiplier is 14, you should be running at much faster then 100mhz. 14x200
=2800. I'm not sure what it is for that particular board or cpu but it's
not 100.

I was bored so looked it up.

It says your cpu should be running at 21x133mhz front side bus.

EGK, do you know the difference between memory bus speed and FSB speed?
I guess that the guy's BIOS is picking up the wrong fsb at boot time.
This happens a lot with shuttles especially if the cpu is a Prescott. I
have an st62K + 3.0 GHz (200 x 15) Prescott & it often boots at 2.49
GHz (166 x 15)

The Front side buss speed is the speed the cpu communicates with the RAM.
