I'm looking for some help getting my overclock higher. I'm fairly new to overclocking and I'm not quite sure where the problem is. Some of my voltages (i.e. VCore) are not necessarily at the values that are required by 3.60 GHz. In other words, I've raised some of them in order to give myself some overhead as I try to get the clock higher. That being said, my current setup is 24+ hours stable in OCCT and Prime95, with temperatures at ~40 C at full load. 45 C in IntelBurnTest. I'm not entirely sure what I can get this system to on air or when I might start to see diminishing returns due to heat, but I'd like to be able to run 4 GHz without any stability issues. If more information is needed, please let me know and I'll be happy to provide it.
My system is as follows:
