Hey guys I just have a quick question for you.

First when i ran at 4.0GHz i needed 1.40 Vcore,

Now after a few days i've gone back to stock settings and then I oc my 920 back to 3.2GHz, now first i needed 1.27500 Vcore for that to become stable but now I see I only need 1.10000 Vcore and I haven't changed any settings?

IS this because my cpu ran at 4.0GHz and is burned in now that I need less Vcore?
