I5 3570k OC HELP ASRock z77 extreme 4

Last response: in Overclocking
Share

Hi

I am looking to overclock my new Ivy Bridge i5 3570k with a ASRock z77 extreme 4 motherboard.
I know very little about OC and am very nervous about frying my CPU.

Newegg TV: Ivy Bridge OC Guide: http://www.youtube.com/watch?v=4mkGQhE1o2w&feature=rela...

I watched this video and at 7min in they talked about ASRock motherboards being equipped with a switch that would automatically bump up the cpu to 4.2GHz. How would I go about doing this with my motherboard? Is it safe, are there any risks at 4.2GHz. Will it automatically bump up my voltage to high and fry my CPU?

I have a Coolermaster Hyper 212 after market cooler.

Thanks In Advance!!

Hi and welcome to Tom's forum.

I suggest you avoid those overclocking videos, specially from newegg. The 1st step to star is read about it, what change and what not change, voltages configurations and those stuffs.

Basically, you need 1st know the BIOS and your components and then move on to change configurations.

Sorry for the late answer...I was busy.

You need find out the option in your BIO for rise the "multiplier" from 35 or "Auto" to 42 and disable all the saver power options.

I have exactly the same component (3570K, Z77 Ex4, 212) and just did the 1st OC on them. a very mild OC, 4Ghz.

here is a guide for exactly that motherboard / BIOS:

Its very detailed. For a mild overclock you only need to change a few settings in the BIOS and do some testing with Prime95 + HW monitor & cpu-z

I did the following

Offset mode
All Core=40
Additional Turbo Voltage: +0.004v
Offset Voltage: +0.005v
Enhanced Halt State (C1E): Enabled
CPU C3 State Support: Disabled
CPU C6 State Support: Disabled
Package C State Support: Disabled

Good guide! I'll shoot for a 4.0Ghz OC first, then try to bump it to 4.2Ghz. Did you have to raise your voltage to achieve 4.0Ghz?

only did the changes listed above.
Max voltage under load is 1.2 for 4Ghz
