I dug the CPUs out of the carton and looked closely at them.
One CPU is clearly marked
750/256/100/1.65v
which I assume is a 750MHz w/256 K cache, 100MHz
Yup.
The other is marked
RB80526P4600256
7007A330-1672
That's an Intel order code, which AFAIK doesn't tell you any more than
core speed and cache (which you've correctly interpreted) unless you can
find it at intel.com (I couldn't).
All Intel CPUs should have an sSpec number on them somewhere - 5
character alphanumeric, first character "S". Find those, then plug them
in at processorfinder.intel.com for all the gory details.
I beleive this is a 600 MHz and I'm interpreting the 256 to be the same as
in the 750. But the voltage? I'm guessing 3.30v -- Is this correct?
Can't be. A 600Mhz PIII has either a Katmai (2.0v) or Coppermine
(1.6-1.8v) core.
If one is 3.3v and the other is 1.65v then these two CPUs will definitely
not work on a dual board, right?
IME a voltage difference is not a problem as dual boards typically have
separate Vcore regulators for each CPU and are therefore able to honour
mismatched VID requests.
