I'm reading that to help with ringing, Intel connects the clock signal to a pull-up of VCore for one clock cycle on 0->1 transitions -- then it is removed and the signal settles to VTT. (Seems like this will help rise rate also.)

If VTT is already ~Vcore, this won't have much effect?
Seems like it'll have reduced noise margin because it'll have more ring?
