So this
600 at 2.0v may only last a couple of years under high usage which I
don't do anyway...

I ran SiSandra on the machine with original BIOS and it said max CPU
500mhz + now I`ve updated to the latest Rompaq released 22/08/1999
and now SiSandra says max CPU 950mhz + so that kinda confirms that a
Slot 1 100mhz Coppermine will run on this board. We already knew that
1.0ghz P3 Slot 1 worked but the question is what voltage will it
supply. I`ll check SiSandra for that info when I have my P3 600
installed.

I think it must run at 2.0v becuase on 22/08/1999 there were no
Coppermine CPU available and Compaq probably envisaged Intel would
stick with P3 Katmai Slot 1 CPU @ 2.0v up to 950mhz + what it does
prove is that my board now officially supports fsb/multipliers to run
950mhz + CPU whereas the old BIOS supported 500mhz + whether it would
of supported 600mhz I don't know but it certainly will now. The
voltage issue is probably why Compaq official max is P3 600mhz Katmai
although they will run Coppermine at 2.0v.

Of course when I say fsb/multiplier I mean multiplier becuase the fsb will
always be 100mhz max. I`ll get the "Unsupported CPU F1 to continue." message
becuase it won't recognise the Coppermine core officially.

I found the PC dumped with a modem and monitor and although I had to replace
the 3.2gb hard drive with a £ 6.50 6.4gb the £ 6.40 P3 600 100mhz fsb
upgrade will make it a very useable Windows XP machine (although the
ACPI/APM won't work) but it has full driver support.

It even had 128mb SDRAM installed and I think originally they came with 64mb
a friend gave me an extra 64mb he found dumped so I got 192mb in there (and
both sticks are PC100 +)

So for £ 12.90 I have a P3 600 192mb 6.4gb Modem CD/Floppy on eBay they
start at around £ 18.50 delivered for P3 450 64mb 6.4gb CD/Floppy no modem.
I normally build my own PCs out of standard hardware but my PCs aren't
available at the moment and there's a nice feeling to taking something out
of the trash and upgrading unexpectedly (as its a crappy Compaq I thought)
it to a reasonable spec for as little £ as possible.

I know this can work for other Compaqs of similar age which may also have
the 440bx chipset and P2 266 - P2 450 an upgrade to 1ghz + maybe desirable
if you like the machine so much you still use it in this day and age.
