New to oc.net forums as I was interested in telling my story
I started off with an Intel 3930k and Gigabyte GA-X79-UD5.
This performed almost EXACTLY like the vcore curve someone else posted :
I ran 4.3GHz at 1.27v and couldn't do 4.5 unless I picked 1.41v as shown in the curve.
Unfortunately during this time the GB burning boards debacle started and I started hearing a VRM buzz coming from my board (got recordings haha).
This lead me to send back the GB board and order an Asus Rampage 4 Extreme.
Now strangely the R4E board clocked my chip to 4.5GHz at 1.32v 3hours prime stable as well as several LinX and IBT runs which passed with flying colors(just did moderate testing).
So I was all happy and stopped doing heavy lifting for a while and started more normal usage like watching movies etc.
Now after 2 days I suddenly had a 0x101 crash, so I was all huh ? retested prime and it locked up within a second.
I then had to increase my vcore all the way up to 1.41v to get it prime stable again...
I could call it cpu degredation but as it already ran at that speed before... can I really ?
Now running 4.3GHz at 1.27v again.
Didn't check my voltages using the OC key in the beginning so I am unable to comment if any of the "auto" voltages increased or decreased.
Obviously pretty annoyed because I really wanted that 4.5GHz but I guess I'm stuck with it as running 1.41v is unacceptable for me.Edited by Mafste - 1/3/12 at 2:30am
