    The drivers I am using do not respond to any PowerMizer settings in the registry. Is there any manual way of controlling the PCI-E 2.0 Bus speed? I'd like to keep it at 1x when I want to. Is there any way of doing this?

    You can downclock it with setfsb, though most of your devices will go crazy.

    Maybe ask a user called Nando4 about that, there is a small chance that you could use bar-edit to set the port to 1x.

    Power saving I think.

    I strongly suggest sending a PM to nando4. He knows a lot about this.

    Yes, Power Savings by switching it to 1x from 16x as well as potentially being able to run the PCI-E Bus at v2.0 instead of just v1.1 for this mobo suports it. This could potentially help overclocking/overvolting etc.
