Your reply was most helpful, the tech docs that I come across often
don't describe components and their functions in layman's terms and are
therefore a bit offputting.

So, pins BF0, BF1 and BF2(if connected) on my MMX CPU are concerned with
clock frequency multiplication, and I hazard a guess that there is
nothing I can do to disable the multiplier limit - x3.5 in this case, as
this is probably set within the package during manufacture.
A x4 multiplier would be useful in my overclocking activities, but
soldering a Mobile Pentium to my motherboard is not an option I would
consider, I just don't see it working.   

SPGA - Sintered?
Does it refer to a ceramic case?.

I'll do some more reading.
Cheers,
