I was wondering why everyone says dont go over 1.3Volts when overclocking the 4790k. What does high volts do to cause damage to your cpu? and when is it acceptable to go over 1.3volts?
I've over clocked my i7 4790k to 4.8GHz with 1.285Volts. my idle temps are around 29-35C. While stressing the CPU the temps are around 65-70C. If I raise the voltage to 1.3 and raise the frequency to 4.9 the temps stay near the same, but after 3 seconds of stressing the CPU it blue screens. I'm trying to achieve the highest over clock possible for my cpu with this cooler. Is it blue screening because the Voltage is to low for 4.9GHz? if so would it be save to raise it even though everyone says dont raise it above 1.3Volts? Or is 4.8GHz the very best possible overclock I can get?
Overclocking made possible with overvolting is a law of diminishing returns. You constantly need a lot more voltage to get ever smaller increases, resulting in boatloads of heat. It looks like you've already found the sweet spot for your particular CPU. I'd be happy with that.
Any ways 4.8ghz is the best i can get. I was trying to get 4.9ghz but i had to get the volts up to 1.325 and it wasnt stable at all. Im pretty sure i could get 4.9ghz if i had the volts to 1.330 or 1.335, but i dont feel comfortable doing that especially since im new to overclocking. Like what you guys said, ill count 4.8ghz as a win.
