Q6600 B3 on a P5B Dlx: delayed vdroop

[Timbosan]

I experienced something similar, but i wasnt running a quad, or the deluxe board. I was running an e6300 @ 3.43 GHz on a P5B vanilla. I also did the vdroop mod and also my vcore increased under load. At first everything was ok, but after one month, the vcore began "dropping" about 0.2v from the stable load voltage, whereupon the chip would fail. I tried (stupidly) increasing the vcore, but this only made the problem worse. I removed the vdroop mod, and even though i have to put up with horrible (0.07v) droop, i have stable voltage under load now. Because you are running a quad, it would put more strain in the board than my chip so you may have different or worse symptoms.
What you have to realise is by doing the vdroop mod you are putting a lot of strain on the voltage filtering capacitors on the mobo. They are not able to cope with the load and effectively buffer the vcore, and the vcore becomes unstable.
My advice - remove the vdroop mod and see if the problem is corrected. I know vdroop sucks, but at least it may be stable.
