Hi all.I don't have the 45nm chip myself.But a friend has one and is reporting the same problems as the threads here.He or I didn't have any answers.But I did suggest to him to do what I used to do if I had voltage fluctuations on my 3.3volt rail.Shut off the pc,Turn off the power,unplug the big 24 pin connector.Then plug it back in and fire up pc.Then my 3.3 v. was back to normal.Now what does that have to whats happening here?I don't know if it'll work or if will do anything at all.But there was mention of a power supply change by someone and the problem went away.So all I can say is maybe try it and see if it works.My friend is going to try and report back to me if he sees any differance.Good Luck Guys.
