Here in the SL-K8AN-RL's Advanced Chipset Features we can adjust the motherboard frequency in 1 MHz increments up to 250 MHz.

We can also independently raise the AGP speed to 100 MHz again in 1 MHz increments. You can change the AGP Aperture size, AGP Rate and HyperTransport functions.

Unfortunately we're not able to change memory timings, only frequency.

The Soltek SL-K8AN-RL is not for the overclocker as the board does not offer any form of multiplier control and voltages are a bit on the low side. Max CPU voltage is 1.55V, AGP voltage 1.8V, DIMM voltage 2.8V and the 1.6V Select is 1.9V ironically.
