What do you think of this Vcore stabilizer? - Page 2

Yes, if they aren't at least as good it wouldn't help, and could hurt, matters. (hence the Sanyo OSCON, Rubycon and Vishay equivalent suggestion for the cap type)

The vcore stabilizer is intended to reduce (or suppress) the drop from 1.13V idle and 1.03V load, both stabilized.

Ah, the drop isn't transitory (temporary), under load it drops and stays that much lower? Sounds like the HIP's auto droop "feature", lol.

Oops, I meant 2.13V at iddle, and 2.03V under load.

The undershoot under load is from 2.03V to 1.95V, 0.08V undershoot.
The overshoot at iddle is 2.23V from 2.13V, 0.1V overshoot.

If I could stabilize the voltage between load and iddle, that would reduce by 0.1V all the variations.

Total excursion today: 2.23 - 1.95 = 0.28V.
With the stabilizer: 0.18V.
