I just couldn't help but wonder what this baby can do with a little
overclocking. Posting solid numbers at its default settings we could
only hope that the Barton would allow overclocking. So off we go
into the Tyan Trinity KT400's Bios to poke around and see what we
can do with the Barton to unlock even more performance. Keeping
in mind that AMD will be offering a 3000+ we could only imagine
what its performance would be. After playing around with the Barton
we found that we could change the multiplier of the Barton with
the Tyan platform via the bios as well as adjust the FSB up to 200Mhz
if the Barton would handle it. The Tyan platform was running rock
solid through all the benchmarks with out a hitch. Feeling confident
in our test platform we started our journey in overclocking the
Barton 2800+. First we pushed the FSB up and we found that the system
would post with the FSB pushed up to 190 Mhz. However the system
would hang when loading the Operating System. So after playing around
a while we found that the Barton and the Trinity KT400 ran completely
stable at 12 x 185 with a the Vcore running at 1.75v. So we ran
a complete round of benchmarks for comparison to our default results.
The Barton runs 2073 Mhz default but with the FSB pushed to 185
Mhz put the Barton right at 2220Mhz. Not to bad that's an over all
gain of 147 Mhz Processor and 37 Mhz bus speed (DDR). Our Barton
2800+ was being pushed to the edge of stability or was it. Never
having been able to leave well enough alone we started twisting
on the ears of the Barton to see exactly what we could get out of
it. Changing our overclocking method of just adding Vcore voltage
while pushing up the FSB we decided to push UP the processor Multiplier
while backing down from the 185 FSB settings. To our delight we
found that we were able to run the Barton with a Multiplier of 13.5,
a FSB speed of 173 Mhz and the Vcore running at 1.75v. This was
our limit for complete system stability. We were able to run the
FSB higher but we would encounter random crashes of programs and
system lockups. A system that isn't completely stable under any
condition doesn't do anybody any good. A system that is able to
post an awesome benchmark result is nice but if it hangs while you
are online fragging your buddies or headed into turn four during
a League race it isn't worth having. Running the Barton with a 1.75
Vcore and 13.5 x 173 Mhz the system was a rock and never crashed
or hung. This put the Barton running at 2335 Mhz. That was an over
all gain of 262 Mhz core speed. I did have one concern with overclocking
the Barton and adding .10 of a volt to the Vcore. That concern was
core temps and would our heatsink handle the Barton with its ears
twisted from overclocking. The answer to this question was simple,
YES. After about 15 minutes of testing the core temps were running
43c under full load. Not bad really considering what the Barton
was being put through. Below are our complete results from overclocking
the Barton. We have included both overclock setups as in some situations
having the extra 12 MHz FSB proved better than having the extra
89 Mhz processor speed.

Final Impressions
After running the Barton through the paces it is easy to see how
the 512k L2 cache has helped increase the overall performance of
the processor. Posting solid numbers throughout all of our benchmarks
and then crushing these numbers with solid over-clockability the
Barton looks to be a force to be reckoned with. An old saying came
to mind while we were tweaking the Barton to the limits of its stability,
"Too much, too much is never enough" and that holds true
for the Barton and its 512 L2 cache. As I said in the beginning
those of you that decided not to upgrade when AMD released the 26/27/2800+
processors your ship may have just came in. The Barton 2800+ looks
to be a sweet upgrade option and its performance increase will be
noticed not only in workstation applications but in gaming environments
as well. Running in a Windows XP Professional environment the Barton
chewed its way through every benchmark we could throw at it and
then was happy to provide us with hours of flawless gaming. During
this evaluation period our system ran 24/7 just like the rest of
my systems. When we were not running benchmarks the system it was
being used to prepare this review, countless hours of UT2003 were
played and with the release of Unreal II and Nascar Racing 2003
Season the system never sat idle in the evenings. Of course everyone
has to sleep from time to time and even then the Barton was pulling
duty as a member of the AthlonXP Folding@Home Team. AMD has done
them selves proud, as this time they just didn't take a current
model processor and crank up the speed. This time AMD has released
a real performer.
