    Asus P5B PCI-E 16x running as 1x Issue

    Anyone remember a fix?

    I have run through the search but can't find anything difinitive. Ideally I don't want to change the BIOS, I am sure I read somewhere to increase the voltage a bit on the NB? But I can't find it anywhere now to double check!

    CPU-Z reports it as running a link width of only 1x.

    Cheers
