S2K Strobe P Control

Common Options : 0 to F (Hex numbers), 0h to Fh

Quick Review

This BIOS feature determines the P transistor drive strength of the S2K bus.

The P transistor drive strength is represented by Hex values from 0 to F (0 to 15 in decimal). The default P transistor drive strength differs from motherboard to motherboard. But the higher the drive strength, the greater the compensation for the motherboard's impedance on the S2K bus.

Due to the nature of this BIOS feature, it is possible to use it as an aid in overclocking the S2K bus. A higher P (and N) transistor drive strength may just be what you need to overclock the S2K bus higher than is normally possible. By raising the drive strength of the S2K bus, you can improve its stability at overclocked speeds.

Please be very, very circumspect when you increase the S2K drive strength with an overclocked processor as you may be irreversibly damage the processor!

Also, contrary to popular opinion, increasing the S2K drive strength will not improve the performance of your AMD processor. It is not a performance enhancing feature so you should not increase the P transistor drive strength unnecessarily.
