  Introduction and Specifications

For most people Soyo Computer Inc. needs no introduction; they've been making innovative and excellent quality motherboards since 1985.  For others Soyo may be a little unfamiliar, because after all, their biggest market is the Asian market since they are based in Taiwan.  Over the years Soyo has been building a bigger name for itself in the North American market and with their latest motherboard, they are surely going to make a big splash, especially amongst overclockers.

This motherboard, as you may have already guessed is the Soyo SY-6BA+III motherboard.  This is Soyo's successor to the popular SY-6BA which was also based on the i440BX AGPset.  So as you can imagine, with a second generation board combined with Soyo's excellent motherboard design skills and the proven performance and reliability of the i440BX AGPset, you've got a potential masterpiece.

Let's begin by taking a look at this board's impressive feature set:

Taking a look at the above specs, this board looks like a regular Slot-1 BX motherboard, perhaps with the exception that it is one of the few boards that has both 5 PCI slots and 4 DIMM slots.  It is also one of the only boards which has an extensive set of hardware monitoring features.  While this already looks like a great board, the beauty of it doesn't start to show until you take a closer look...
