I'm a little bit confused with my system/CPU and why I can't get it to overclock very much. It seems the most I can overclock my i5 4670K to is 4Ghz. Any higher and the PC acts up, freezes or resets. It won't even let me increase the voltage either. I tried increasing it by a tiny amount - from 1.000 V to 1.005 and I instantly get a 'blue screen of death'.
I understand that results vary from computer to computer when overclocking components, but could there be something else I'm missing in this case? I mean, the system won't even let me TRY increasing the voltage a tiny amount to experiment. Could my PSU be partially responsible too?
Also, it seems with every GPU I've bought, I've never been able to overclock them by very much, and the results have yielded no improvements to game performance from I can tell.
Those autotunes usually don't result in that great of an overclock, it is best to do it manually. Also, it is a good idea to clear cmos by either removing the battery or using the clear cmos jumper on the motherboard, it makes sure you don't miss any settings when returning to stock configurations.
Okay. I'm still concerned about the Vrin/CPU Input Voltage part as I can't increase it to what that guide says. Also, some of the names of the different voltages in that guide are either missing from mine or they're named differently, so I'm not 100% sure.
From the screenshots I've provided, could someone clarify which ones need to be changed and to what? It would be much appreciated.
Could my PSU be the cause of not being able to increase/decrease my voltage? I don't understand. My motherboard is a 'Z'97 model and my CPU is a i5 4670'K' chip. Overclocking should not be a problem. Maybe the PSU isn't powerful enough? "/
