This evening we will be taking a look at the new KT3 Ultra
ARU motherboard from MSI. This is the first of what
will surely become a long line of motherboards to
incorporate the new VIA®
KT333 chipset. The new chipset offers a number of new
features to help propel its performance beyond that of the
popular KT266A. In addition, the system comes with the
VIA® VT8233A Southbridge
chipset which brings a number of new standards to the table
claim to fame of the new
VIA® KT333 Chipset is the
added support for PC2700 DDR RAM, allowing for 2.7GB of
memory bandwidth at 333MHz. Coupled with the Northbridge, the VIA®
VT8233A Southbridge offers support for USB 2.0, which
increases transfers from 12Mb per second with USB 1.1 to
400Mb per second with USB 2.0. The new ATA133 standard
is also incorporated into
the Southbridge, providing IDE burst rates of up to 133MBs
per second with ATA133 compliant hard drives installed.
MSI is one of the first
motherboard manufacturers to incorporate VIA's new chipset.
What they came up with is a motherboard that offers both
performance and new features that should make it a stand-out
product in an otherwise crowded market. It's
quite obvious from the start that MSI has taken great
strides to put together a complete system. So, let's
take a look at the details of this new KT333 based
motherboard and then we'll go over its features in more

The MSI KT3 Ultra-ARU is one impressive board right out of
the gate. With a plethora of features and a spiffy red
PCB, the board immediately grabs your attention with its
quality appearance and craftsmanship. It is clear that
MSI has taken the extra step here to assure customer
satisfaction. The package comes with a good complement
of utilities and support software as well as all hardware
needed to take full advantage of the system's potential.
The Drivers/Software CD has a clean and easy to follow menu
that gives you easy access to all of the software on the
disk. Whether you need to install drivers or want to
try some of the utilities included on the disk, it is all
easily accessed through an intuitive menu.
Live Update BIOS
One of the more
helpful applications included on the CD is the MSI Live
Update Utility. Live Update checks the systems current
BIOS and driver versions and notifies you if any updated
versions are available. With a simple click, all of
the files needed are downloaded and installed in one smooth
I must say that
I do have mixed feelings about this. Downloading
drivers is one thing, but downloading and updating the BIOS
through Windows sounds a bit risky to me. When you
flash the BIOS from a boot disk, minimal system functions
are running, minimizing the potential for something to go
wrong. If the BIOS is updated while Windows is
running, there are a lot of variables that could effect the
flash, which would render the board useless. We did run the Live Update during testing and it worked
flawlessly. However, we've heard stories of other
readers who have used similar utilities with other products
and they killed their board, even though the process
appeared to complete without error. When it comes to
flashing the BIOS, I recommend using the boot disk technique
to play it safe. Regardless, especially for the novice
users out there, this is a nice complement to the product.
has put together a fine package to accompany a fine looking
motherboard but we all know that you can't judge a book by
its cover. So let us roll up our sleeves and delve a
