And that the computer is somewhat less likely to give you the right
answer, particularly where complex calculations are concerned. (Note: if
this could be a problem, you should get a computer with ECC memory,
since non-ECC memory also very occasionally returns the wrong answer.)

Except that to the best of my knowledge, they didn’t sell a 510 MHz
Celeron: the closest were 500 MHz and 533 MHz. It looks like the
computer has already been somewhat overclocked (or possibly
underclocked).
This Celeron is almost certainly one of the Mendocino family (check the
model name line in /proc/cpuinfo), which is essentially a Pentium II
with a different cache system. Intel never sold any of these processors
at speeds above 533 MHz, despite considerable commercial pressure to do
so, so I’d doubt it can be made to go much further anyway.
Hope this helps,
James.
