Many thanks for that, Wes - no success I'm afraid.
Your first suggestion resulted in locking-up and I had to reset the CMOS.
The maximum multiplier available in BIOS set-up is 12.5 and above. Using
this, I still get the CPU reported as a 1300MHz thunderbird. Thus, I get the
same result whether I employ user-defined or not.

So, in other words, as long as you keep the FSB at 100, everything works.
And anytime you set the fsb to 133 it fails, even if you chonge the
multiplier to let's say 9? If that's the case, it's not the cpu. It's more
than likely your ram now working at the speeds you have it set for. The
ram bus follows the FSB, so when you raise the FSB fromm 100 to 133, the
ram bus speed increases to 133 also. And your ram isn't working at that
speed. It could just be bad ram that won't operate at 133MHz, but it could
also be how you have the ram set up in the dram section of the bios. And
it moght be the PSU too.

Forgive my ignorance , but I do not understand what you mean by looking
at my ram/timings. I've got 768 of 133 RAM. Any other suggestions would
be welcome.

Pull all the ram except 1 stick. Manually set the ram settings to the
slowest, cas 3, 80ns (I think). Now set the cpu multiplier to 9 and the
FSB to 133 and see if it works? If not, try a different ram, repeat. I
assume there's lots of ram tutorials on the web, try and find one.
