The default reset value of the MSR is 0. If BIOS doesn't intialize

initialize the MSR with value of 7 for balance between performance
and energy savings
Is there a noticeable performance or energy savings difference? If so, I
guess this will some time depend on the load or some other setting (like
a laptop that is or is not connected to the power supply)?
Bye,
