Overclocking i5-4690k to 4.0GHz

[EvooHD]

Hello, im interesting to overclocking my i5-4690k 3.5GHz base clock to 4.0GHz

Motherboard i have is: MSI Z97 GAMING 3
the only things is that i have Intel stock cooler running at 95% almost maximum speed. So its cools everything down, right now i have 3.5GHz at 95%


I wondering if i can do 4.0GHz?? and if i can, how much i need increase Vcore voltage? or mybe there are Autotune option on MSI?

Upgrade your cooler first of all. After that, you probably only need to go into the BIOS and change the little field that says Multiplier 35 to 40.

Yeah get a better cooler. I have a 4670K and all I did was bump the multiplier to x42, didn't need to mess with voltage at all. CPU is overclocked from BIOS, not from a program like MSI AB.

See how far you can go without having to bump the vCore, I'd advise against touching the voltage on stock cooling..

Also, leave the cache multiplier where it is for now - I spent a long time trying to figure that one out!

4590K @ 4.6GHz here
