Haha good lord. 1.27v for 4.6! I need 1.4v for my 4.6!
Sucks because temps are not an issue for me.
As far as running 4.6 GHz at v1.28, its been going for 15 minutes so far with max temp being 74c. If I can run it for 2 hours with a max at 75c, I'll be happy. I may even try for 8 hours, but seeing as I have to go out it might be better to wait.
Just as I'm typing this, it spiked to 76c before dropping... I'll still take it though!
