Trying to monitor the effects of no VDROOP with a multimeter is like attempting gene splicing with a magnifying glass and a couple of nails. Without a fast scope the overshoot Tony mentions will never be seen. The VDROOP circuit is an elegant design because of its simplicity and cost effectiveness of eliminating what can be a catastrophic failure.

Properly implemented, VDROOP in no way hinders a 24/7 overclock. All one has to do is look through the DFI P35, X38/X48 threads to see the number of users successfully implementing VDROOP and C1E with their overclocks.
