Why do I need so much voltage for 3.0GHz?

post #1 of 3
Thread Starter 
Hey guys, I finally ended my OC'ing sessions cause I got tired! I'm 9 hour ORTHOS stable at 2.88GHz, vCore at 1.4v.

My question is, why is it that I needed to raise the cpu voltage to at least 1.45625v to get 3.0GHz when I can do 2.88GHz with just 1.4v? Is this just one of those ocassions that prove how every system is different? Cause I see many people with vCores in the 1.35's achieving 3.0GHz.

THanks for any input!

Depends on the chip more than anything, upto a point for every extra 50Mhz or so voltage requirements jumps up a lot to get it stable. I would be chuffed with your current OC to be honest.

Thanks, yeah I mean I'm happy and 100% satisfied with the 2.88GHz considering stock is just 1.8GHz. I just wanted to know why 3.0GHz was so unstable and yeah I guess is my CPU that can't do very high FSB....
