Chaintech uses the standard Phoenix AWARD BIOS with little modification. The POST screen has the clock speed of the CPU, memory speed and timings. It's pretty cool to see the information at boot, as you want to make sure the CPU is actually running at the expected clock speeds. Another nice touch is the inclusion of a POST code, allowing for easy troubleshooting of problems. If an error occurs, the POST code will reveal the likely culprit.

Overclocked
I fooled around with overclocking on the Chaintech nForce4 Ultra board a bit. With the stock AMD Athlon cooler, I was successfully able to overclock the CPU to 2.6GHz. While this isn't a big overclock, the problem is with the CPU in question, more than the board itself. The AMD 4000+ we use in every day testing doesn't overclock that well, making even a 100MHz overclock an ok look.
