Generally, it is best if your motherboard vendor has a list of
supported CPUs. Sometimes a newer BIOS is required to make them
work (microcode patch update, parsing corrections, or the fix for
reading a 3.0 as a 2.8GHz etc). I frequently try to advise people,
by examining the entries at processorfinder.intel.com , but
that doesn't cover any motherboard quirks.
A 3.0E has the same TDP (thermal design power) rating as the 2.4A,
so the same Vcore converter should work with both. The 3.0E
Prescott will require more Vcore, as set by the VID signals
(no problem there). So, your MSI board may be BIOS limited, and
you'll need to look on the MSI site, to see if they provide the
amount of detail needed. You can always plug it in and try it.
The worst that will happen, is a lot of beeping, and/or no video.
What is the deal with Prescotts ? Higher leakage current, due to
smaller transistors. That wastes power without doing any useful
computing work. Prescott also has a deeper pipeline, so more
stages running at core speed. Prescott in S478 is a lot like
the early Pentium4, it looked like a loser, but was much
better when it ran at higher frequencies. So the architecture is
suited for higher operating speeds (i.e. you are paying for the
infrastructure of a 4GHz+ processor, but without running at
that speed.) But for owners of S478 motherboards, the only way
to find out, will be by using S775 LGA packaged processors. So,
you won't get to enjoy whatever benefit the Prescott may have to
offer at speeds greater than 4GHz. The extra signals on the S775
socket are there to handle more current.
