As you can see here, Soltek gives us quite a few options to play with in the SL-K8TPro-939 BIOS, though we would have liked to see more memory tweaks. You can also adjust HyperTransport speeds as well as tweak your AGP settings.

In the Frequency/Voltage Control section you can modify the CPU multiplier in whole values only, no half multiplier options. Motherboard clock speed can be adjusted from 200-300 MHz in 1 MHz increments. Maximum CPU voltage is 1.7V, AGP is 1.8V, memory is 2.8V and Northbridge is 2.8V.
