    I believe your mean multithreading. I also believe multithreading should be enabled at the bios level.

    **EDIT **

    Logical Processor
    The logical processor feature is based on Intel’s simultaneous multithreading (SMT) technology. SMT enabled systems appear to the operating system as having twice as many processor cores as they actually do by ascribing two “logical” cores to each physical core. SMT can improve performance by assigning threads to each logical core; logical cores execute their threads by sharing the physical cores’ resources.
    To enable the logical processor feature in the server BIOS, select F2 on the server boot up screen and then select the following options:
    Processor Settings -> Logical Processor, Values=Enabled (default), Disabled
