I think yours may have been more pronounced, and by upping the vdimm you got it to where mine was; slightly present.

The thing is, my Maximus II Formula does not do it, even when using less vdimm that I was on the deluxe, and the same vcore, vFSB, vNB and vSB.

What vFSB & vNB are you using on your board?

One thing you could try - raise the vFSB a little. Try to keep the maximum vdiff between the vFSB and vNB less than 0.12v, such that the vNB is no more than 0.12v higher than your vFSB.
Thanks CryptiK...yes, what you described is exactly the symptom I have. I've got vNB at 1.24v and vFSB set at 1.14...but I haven't touched vFSB at all thinking I had it maxed. Read the intel spec sheet again, though, and it says you can go to 1.26v on vFSB...so I can try bumping that and see if that helps...but, yes, that power drop always give me the feeling it's going to fail post...and then it does sometimes.
