no much higher is not possible, I can get to 4.4 at a vcore of 1.437 in the bios, but that wont give me much more performance compared to 4.2 in gaming, I don't think it will give more performance then 4.0, just like to overclock but for more then 4.4 I need to much vcore, I think about 1.50.
just whant to now what you think of getting my temps down, with settings is best to use
