FWIW, the Tyan S1832 board is also known as the Tiger 100; keep that in mind as you read this...
I saw NO provision to overclock the CPUs though BIOS / CMOS settings, so don't count on being able to do that. Page 35 in the .PDF manual shows that the Tyan board requires the use of SPD (Serial Presence Detect) SDRAM, so that could present a problem if you don't already have SPD SDRAM that you KNOW will work with this board.
There is also an "addendum" for the board, which you can read here:

Tyan makes great products, but this board doesn't seem to be designed for overclocking.
According to this page:
http://www.tyan.com/support/html/PentiumII_III_PPGA.html
the S1832 board won't take a Pentium III faster than 600MHz, UNLESS you happen to find a revision F (or later) version of the board. The "Rev. F" (and later) boards can accept the PIII Coppermine CPU with 100 MHz FSB up to 850MHz; the Tyan S1834 board (note the different number) works with 100MHz FSB Coppermine CPUs up to 1GHz, and also accepts 133MHz FSB Coppermine CPUs up to 933MHz. That board is known as the Tiger 133.
You can download the .PDF manual (in case you want to store it on your harddrive) from this link:

The latest version of the BIOS can be downloaded here:

Keep in mind that Coppermine CPUs (with 256KB full-speed L2 cache) run at a LOWER voltage (1.65V) than the older (2.0V) Katmai CPUs (which have 512KB of L2 cache running at half of the chip-speed), so if you install Coppermine CPUs on one of the early boards (BEFORE Rev. F), you will probably destroy them. If you DO find a Rev. F board, which supports the Coppermine 1.65V CPUs, you could probably install 1GHz CPUs, but they wouldn't run faster than 850MHz, which is the top speed setting for the Tiger 100 board...
If you already have two 1GHZ PIII CPUs, your best option might be to look for a Tiger 133 board, but make sure to get the proper SPD SDRAM for it, and don't expect to overclock it.
Good luck; hope this helps you decide what to do next...
