Part 2
We didn’t like where we were….so we took
off in another direction...
Determining which motherboard to choose and deciding whether we should opt
for an Intel or AMD platform was a source of much debate within our ranks.
We were intrigued by the
Albatron PX845PEV Pro motherboard which was
introduced about the time we started this project. By all accounts this
motherboard which is based on the Intel i845PE chipset was a great
overclockers, had a very nice feature set, and was well priced for what it
delivered. After reviewing the PX845PEV Pro, we knew it would become a
part of this project.

We decided to match a P4 2.4G Northwood and
a 256MB Corsair XMS3200C2 memory stick with the Albatron PX845PEV Pro
motherboard.

Well, now we were set, right? Wrong! Once
again the seeds of uncertainty reared their ugly head. We came to the
conclusion that we were not leveraging our CalPC server case to its full
capabilities. In order to maximize its full functionality, we just
“needed” another motherboard. Now that we decided to change course, we had
to decide on the next motherboard and platform to use. We concluded that
the nForce2 chipset was much too promising to pass up. We got our hands on
a Chaintech Zenith 7NJS motherboard which made our decision
an obvious one.

The processor of choice was the XP2600+
which runs at a 166 FSB at default. In order to take advantage of the
nForce2’s dual channel memory, we acquired 2 sticks of our favorite
memory; the Corsair 256MB 3200C2.
What was once a clear vision turned amorphous. Now it was regaining shape,
but there were so many decisions that still needed to be made…we were
still wandering in the dessert.
Part 3
Some one needs to establish some order. Time to lay down the law...
At
this point our salvage project had unofficially gone by the wayside. It
was time to regroup and decide what our driving principles and desired
outcomes would be. We decided on the following:
1. We
had to live up to the name ExtremeMhz and everything it implied. Our
focus was now on maximizing our dual system’s performance. We had already
taken some steps towards this end through our choice of motherboards,
processors, and memory.
2. Cooling
was going to be of primary importance. We wanted to experiment with the
newest water blocks on the market. In addition, we also wanted to try our
hand at the next level of cooling through the use of TECs (Peltiers) if at
all possible.
3. In
keeping with the theme that was now being established, our storage
subsystem had to perform at a level consistent with the rest of the
components.
4. For
aesthetic purposes, all components should be self contained where
possible.
5. Performance
was the name of the game for this project. Modifications were to be
limited to increasing functionality. Sorry, no windows or glowing fans
this time around.
6. The
sound of 2 systems operating concurrently with all the cooling we
envisioned could very conceivably lead to very uncomfortable noise levels,
therefore, every attempt would be made to balance performance and to
manage sound levels in order to make the user’s experience as enjoyable as
possible.
7. The
involvement of our faithful is important. We established a
Work Log for
this project where forum members were encouraged to participate in the
outcome.
8. We had to
differentiate ourselves through innovation.
