Overclocking I7-4770K with MSI Z87 G75 BIOS

LittleKat · Apr 7, 2014

Hello everyone ^_^

I'm new to CPU overclocking and wonder if anyone can give me some hints on how to overclock the I7-4770K with MSI Z87-G65 BIOS @ 4.4Ghz. As of this moment, I'm reading articles about overclocks to find out more about it. Hopefully by the time I got some replies on this thread I will be able to understand and but em in action! ~_^

What I'm looking for exactly:

CPU Multiplier: 44, CPU Frequency 4400. (Just figured out about this)
CPU Ring Ratio:39 (3900)
CPU Voltage ? (1.2 or...?)
CPU Ring Voltage ?
System Agent Voltage ? (+?)
Anything else that I missed?

I had the following programs for testing:

- Prime95: Test for stable overclocks.
- CPUz: List current clock speeds and stuff.
- CPUID HWMonitor: Temperature.
- Command Center and MSI Extreme Tuning Utility: something extra but quite useful.
- All drivers and BIOS are up-to-date.

Thanks for dropping by & have a wonderful day! ~^_^~

overclock.net has a great guide for gigabyte motherboards. Still full of detail for other boards.

Quick and dirty. vcore 1.25 get you to about 4.3Ghz, 1.3v 4.5-4.6, 1.35v 4.7-4.8 Ghz, and you have to have fantastic cooling to handle 1.35 volts, so be wary.

You've already reached the point where the ring ratio should be increased along with a nudge to the Ring voltage.

Vin (power supplied to the VRMs for the CPU) is another important value. 1.7-1.8 for 4.5Ghz, 1.9-2.0 for higher.

Mind that there is a wide range of Haswell performance. My chip is particularly terrible at overclocking temps, but very stable.

Here is a guide that I found to be very useful: http://www.tomshardware.com/forum/id-1722630/intel-god-quick-dirty-guide-4ghz-haswell.html
