Asus P4B and Northwood 1.6A

[Rhianntp]

I need a little help understanding something about this board...
the cpu frequency setting is the bus speed right?.. ok...
if i want to overclock this cpu i need to raise this setting.. my question is at what point do i need to change the cpu/ memory frequency ratio thing to 3/4 insted of 1/1... or does leaving it at auto automatically switch for me...?
also does anyone have any info on which FSB setting corrispond to ceratin agp/ pci bus speeds?.... my tusl2 shows the numbers int he bios.. but on p4b they dont ....
and whats a safe operating temp for this MB & CPU?
id really appreciate any info yall might have..

ill gladly post my O/C results here afte i figure these issues out..


thanks

I keep mine at 3:4 till 132 hz, the board automatically puts it to 1:1 at 133hz and higher, if you get instability problems, change it back to 1:1, good luck!

ok... i have a P4B and 1.6A

i set it to manual in bios and set clock to 124Mhz... and using turbo1 mode... everything else is on auto... runs great @ 1980 MHz
am i assuming right that turbo1 mode is running my pci and agp within spec?
when i play quake 3 for a bit the cpu temp pushes to 50C... other wise its about 42C....
does all this sound good??

I've got a P4B266-C, and I'll be damned if both the BIOS and AsusProbe report a 40 degree processor. It never EVER changes, no matter WHAT I run or how fast I bump up my CPU. Has anyone gotten this working correctly?

Use Motherboard Monitor 5, Sensor 1 use Asus 2, Sensor 2 use Asus 1 , mine doesn't read 40C anymore when these are used.

i have that same problem with asus probe, it always says my proc temp is 40, the motherboard temp changes as the ambient air changes. is it just the program or is the reading true?

Well I have a P4B not to be confused with the P4B266. Not sure if this helps but I found the CPU/AGP/PCI ratios listed on page 2-19 section 3 figure 2-24, in the manual if you can believe it.
