You could underclock the 550 to 450, which would give the most stable
AFAIK, the 550 is not multiplier-fixed so you should be fine.
just run the 550 cpu at 100 x 4.5.
If you have adequate cooling and a beefy power supply (like 30+ Amps at 5v),
you could increase the core voltage by a notch and bring the FSB up to the
likes of 110mhz or higher until the system becomes unstable.
Then you would attain your 2x 495mhz status :)

Subject: [ILUG] Mixing processors?
I've a Dual PII/PIII board. At the moment I've two PII 350 processors in it.
I've had a 550 PIII for a while but didn't think it would be better than two
PII 350's. I've now got a 450 PIII and was wondering if I could
over/underclock them? I was thinking that underclocking the 550 down to 450
would be safer.
The other thing I was considering was splitting the difference and running
them at 500Mhz, but I'm worried about over heating?
Or would I be better just holding out until I could find a matching 550 Mhz
