Mostly likely it will run at the correct frequency but
merely not be able to make a positive ID on the CPU. It may
correctly display the operational speed, or may display
something *wrong*. For this reason it is necessary to
confirm the speed with alternate methods as mentioned
previously. It is least likely that it would run at 950
instead of 1000MHz. More like it would not POST at all, but
the odds are it will.

I cannot guarantee it, but think it is worth trying. If
there is a newer bios available you might want to update the
bios, particularly if the board has a relatively early bios
version. This may combat other bios issues in additon to
CPU identification.

"In general" such boards did support 1GHz CPU, within the
limit of the [no support for 133FSB with non-'A' KT133] it
was the issue you mentioned that they simply didn't have
that speed yet when the spec for the board was produced- and
with lesser board brands/support, they may not update their
specs for it later, and sometimes won't even fully disclose
the changes a particular bios incorporates if there's even a
newer bios available. After flashing a bios, clear CMOS.

No, KT133 non-"A" does not actually support 133FSB. It does
not matter if it has a jumper. Other non-supportive boards
also had such a jumper. Via originally had intended to be
able to get KT133 running up to 133FSB, but wasn't able to
and shipped out the chips they had at the time. LATER they
got 133FSB working right and this was the distinction of
KT133A.

Not so easy to assume, the board itself can be an issue even
when memory is spec'd higher, especially when a board looks
up SPD info and finds a module spec'd for (as an example)
CAS3 @ 133MHz but CAS2 @ 100MHz. In such cases there is the
potential for it to still be running the memory at most
aggressive CAS timing possible. Resolution if there were
this kind of problem is obviously different memory, or
manually setting a higher CAS #, or other things we need not
delve into at this time.
