Hello, I have an intel core i5 750 cpu + asrock p55 pro motherboard and I want to overclock my i5 to 3,6-4GHz and I am just confused with this board's voltages. I am coming from msi p55 gd65 where only 1.264 vcore (1.200v after vdrop) could do 3.6ghz. Now I see that this board requiers pll and other stuff increasing. Anyone having this combination of mobo and cpu could help me. I just don't know what is safe and what isn't safe with this board in therms of voltages. Also to mention that I got Noctua NH-D14 and HAF 922 case. Thankyou
I would suggest max PLL of around 1.9V and VTT (QPI or whatever your board calls it) of 1.35V. Let me know if there's any other voltages you're unsure of.
To add on to Uxon's post, maximum PLL recommended by Intel is 1.98V and max vcore is 1.4V. Having said that, the MSI board you had ( and the one I currently have ) suggests a maximum safe for PLL at 2.05V and vcore at 1.45V so you still have plenty of volts to play with I'd put your VTT at 1.2ish and PLL at 1.86ish as they're the settings I use for 3.8GHz. You could probably go lower than that as well if you can be bothered to stress test every time you change a voltage
