Been playing with it a bit and it's working. Thanks!
I tuned the LLC and the offset so that the load vcore is the same as it was before and it seems to be just as stable. The only difference now is that the spikes are gone and my idle vcore is low (since the offset is lower).
I didn't zero the offset. I turned it down by a lot though.
I didn't realize the LLC increased the base voltage as the load is increased. During the original i7 days, LLC only eliminated the vdroop (with very little overshoot). I turned off LLC because of the unwanted voltage spikes and the rumors that it was killing CPUs.
Now, LLC seems to actually increase the vcore - so I don't have to (as much). I guess SB is very different. (or at least the mobo...)
