Hi,
We many "PowerEdge R620" servers used as Database servers.
We are unable to enable Hyper Threading on these servers.
It is enabled in BIOS , CPU supports it , not disabled in boot loader

Question
1) How to enable Hyper Threading
2) How to get / set Max Boot or Tubro CPU Speed ( Turbo Boost is enabled in BIOS )
3) How to change match / enable Memory speed what it is capable of
