Sorry, I could have been more specific in my question. I have a server with
2 Xeon PIIIs already in and there were 2 more Xeons available to buy. These
have the same stepping as the ones I already have, but a different (bigger)
cache size. I was refered to Intel's Processor Specification Update by an
earlier post, but this seemed non-comittal on the question of differing
cache sizes, so I asked the question. I've bought the two extra processors
now, and I'll be happy if they work as if they are two more of what I
already have.

Thanks for your reply.
