Re: P4 2.8 FSB 800 overclock. Any ideas?

<<"The Springdale chipsets are reckoned to be the poorer cousin of the

helped matters here."

This way they were able to increase the FSB without increasing the
effective core speed, by using a lower multiplier. For example, 10x285
would yield 2850MHz much in the same way that 14x200 would yield a
comparable 2800MHz.

In overclocking, there are many limits to be aware of. FSB speeds,
core speeds, voltage levels, memory timings, power consumption, heat
generation... the list is endless. Some of them are fairly obvious,
but others are a bit tricky to isolate. The relationship between FSB
and ultimate CPU speed can be one of these tricky things.

What motherboard were they using that allowed them them to change the
multiplier?

Asus P4P800, but keep in mind you won't be able to adjust the
multiplier unless you have an unlocked CPU. These are hard for normal
consumers to get ahold of as they are typically sent to reviewers as
preproduction samples from Intel.

You make a very interesting point in that the stock ASUS P4P Deluxe is the
motherboard in question, and it has no capability to change the multiplier.
So now the question is what is a "semi-unlocked processor", and how would
that make any difference anyway?
