Hi,
THe speed of the machine is determined by the CPU, so your system will
run @ 133 MHz. You can still try the slower memory, but you are
"overclocking" it from 100 to 133 MHz with all of the related problems,
like heat, instable working, errors, random hangups, etc. -- assuming it
does work at all.
There are some RAMs that were supposed to run @ 66 and run @ 100, as
well as 100 MHz RAMs that run at 133, but I suggest you to walk on the
safe side and purchase a new 133 MHz stick of RAM.
Why? Remember the saga of Celeron overclocking. A lot of Celerons-300
can be overclocked to 450 (a 33% increase), but only about 2-3% of
Celerons-400 (when they were still manufactured :) can be similarly
overclocked to 600. The reason is that Celerons-300, as the SDRAM-66, are
at the bottom of the same production line and have a much wider "safety
margin" that is used when overclocking. The faster chips (Celeron-400,
SDRAM-100) have a slim reserve of speed and, as a rule, can not be
reliably overclocked.
But the Celerons-400 can be overclocked "in between" -- between 400 and
600 there are 450 (60-70% success) and 500 MHz (10-20% success) steps.
With the memory, you don't have these intermediate values - you choose
either 100 or 133. So the chance of failure is higher.
But you can always try... Maybe you've the lucky stick of SDRAM :)
