Introduction

The Soyo SY-TISU is one of the first Intel Pentium 3 "Tualatin"-compatible boards to make it to market.

Unfortunately, we experienced quite a few problems testing it when it first arrived at our lab, which caused us to set it aside for a later time. Recently, though, we were quite happy to invite it back into out lab, at long last. Even though the SY-TISU hit the market only shortly after the original Intel reference board, it still manages to pack-in a fair number of Overclocking features. That just goes to show how competent Soyo's design team is; it takes a certain amount of moxy to put together an Overclockable board so shortly after a reference platform's introduction.

So, without further ado, onto the tests...

The Soyo SY-TISU is just as versatile as any other Tualatin board we've reviewed to date. It's entirely jumperless, with most of its functionality programmed and accessible through the BIOS.

The first BIOS feature to hit most users will of course be the "Soyo Combo Features" menu, for which it is possible to set the FSB frequency to between 66MHz and 255MHz in 1MHz increments.

Next, a second function allows the clock multiplier to be set to between 4X and 12X.

Finally, another option permits users to adjust the processor's Vcore voltage, as indicated by the table above.

Memory timing options - including the option to adjust the memory bus frequency - are located within the 'Advanced Features Setup" menu.

In short, the SY-TISU has been supplied with a fair range of Overclocking functions, and is well-equipped to take advantage of a CPU's true capabilities.
