I did my CPU OCing with a 1:2 divider on. I am guessing that at half the speed of my CPU my ram wasn't the issue
Not only did I use a 1:2 divider I even pushed my vcore up to about 1.7 just to see if it would allow me to go higher and the stupid thing maxed out completely at about 2.81 ghz and was hardly able to even boot into windows letalone be remotely stable.
God hates me thats all there is to it.
And I have no money cause I used it all up on my crap OCing chip and the rest of my setup.
I need to make a smiley that holds a gun up to its head and pulls the trigger.
EDIT: I think I have a 5:6 mem divider set to even handle my crappy 2.7ghz OC
