Motherboard offerings are really beginning to get overwhelming.  Why is this you ask?  Well, for starters Intel finally has true competition with AMD firmly perched in the heart of its mainstream PC product offering.  With a well rounded and entirely new platform now entrenched in the market place, there are easily 2X the number of motherboard flavors available from any given manufacturer.  Not to mention the fact that VIA has proven itself to be a formidable opponent to Intel in the chipset market, offering solutions for both CPU platforms.

As a result, the testers at Hot Hardware have their hands full with new products to test.  What a wonderful problem to have.  This is a look at the AMD side of the fence.  Soyo, long known for its high quality Intel based motherboard offering, has recently released a long awaited VIA Apollo KT133 based motherboard.  Sporting AGP4X and ATA66, the SY-K7VTA has been eagerly anticipated as a Socket A solution from a manufacturer known for catering to the high end.  Let's see if it hits this mark.

Specifications / Features Of The Soyo SY-K7VTA
Standard issue VIA based product but where's that #6  PCI Slot?

    One game port

Let's run down the short list.  AGP4X, ATA66, PC133 Memory Support, On Board AC97 Audio and PC Health Monitoring are all standard fare for the VIA KT133 chipset.  Soyo pretty much went by the book with this board.  It does offer a comprehensive CPU Setup in the BIOS which provides for some ability to over-clock.  We'll take a look at this shortly.  However, beyond that there is not a lot that makes this board stand out.  There is no ability to set the CPU multiplier as we have seen on a select few boards available currently. 

Finally, Soyo decided to configure the SY-K7VTA in a 5 PCI / 1 ISA setup.  6 PCI slots would have been preferred and it is quickly becoming the norm with most recent generations of chipsets supporting this configuration.


Soyo does a very nice job however, of providing excellent filtering and signal conditioning with its abundance capacitors and chokes (the round torroidal magnets with copper wire windings on them, you see in the above shots ) around the CPU socket and other areas of the board.  This board should prove to be very stable as a result.  We'll provide more detail in the following pages in that regard.

The BIOS is sort of the "heart" of any motherboard giving you critical control over the performance and setup of a given system.  Let's look at what Soyo brought to the KT133 party in this area.
