P3B-F motherboard

[Steve]

Hello,

I am new to this group. So if this has been posted before I apologize. A
friend of mine gave me a computer with a P3B-F motherboard with an Intel 450
MHZ 100 MHZ FSB Slot 1 processor in it. I would like to get an 800 MHZ 100
MHZ FSB Slot 1 to replace the old processor. I recently flashed the BIOS to
Revision 1008 beta 4. However after poking around in the BIOS settings, I
noticed that the lowest core CPU voltage setting is 2.0 volts. The 800 MHZ
processor needs a core voltage around 1.7 volts. Will this make any
difference? Thanks in advance.

I'm sure from a theoretical perspective, it's not good to exceed the
recommended voltage of a cpu. In the long term, it may shorten the life of
a CPU. But from a practical/realistic perspective, the cpu should be able to
take that kind of voltage. The cpu may run a little hotter than it could
run at. You do it at your risk, but there are probably tonnes of people
that run it at so high voltage levels. Perhaps, it would help to get better
cooling in the machine.

The lowest voltage setting is just 2.0 volts because the board doesn't
allow you to undervolt (stupid asus boards are all like that, at least
the newer ones). But if you insert a different cpu the lowest voltage
setting will be different.
That said, if you have a really old board (pcb) revision (below 1.03), I
believe they are kinda rare, then chances are your onboard voltage
regulator will not go down below 1.8V, and in such a case it will not
work with a slot1 coppermine processor, at least not without hardware
modifications (cause the voltage regulator will shut down if it sees a
VID coding it doesn't understand).

I have a really old P3B-F, running a 800MHz Coppermine, and the CPU's
voltage is at 1.696v based on CPU-Z.

Do you know what revision your motherboard is?

Always cracks me up to see a post like this about an asus BX
motherboard running a PII and being handed off to someone else.

People have NO IDEA what they've got or what to do with it.
