IIRC, most people hit mid-70s @ 4.5ghz....I hit 80C @ 4.4ghz!! No fair! mad.gif My voltage is very low though...I might just need to redo TIM and reset heatsink, but lazy. lol.

O well..just the luck of the draw. Silicon lottery.

FYI - I updated my previous post. I talked about the stress test settings I used...you might want to try it, and see if you are still stable - if you have time...but I think you are fine. Maybe just to IBT for 20 rounds (quick stress test) if you don't want to redo Prime95 for 12 hours with high RAM usage.

Hello, it would be my first time to overclock my newly purchased asrock z68 extreme 3 gen 3 with 2600k and I was wondering what the guide meant by increasing and decreasing the voltage?
Does setting -0.005v to -0.004v considered increasing? or decreasing?

The undervolting method seems the perfect method for me since I don't plan to push my cpu to its limits. At least, not yet. I'm totally content with 4.5ghz. So, my other question is would it make a difference if I take two or three steps to get to 4.5 ghz? I mean do 4ghz then 4.5ghz. Is 4.5ghz considered a mild overclock as mentioned in this guide?

Thank you very much. Have a great day!

4.5ghz is the standard target most people can hit with some BIOS tweaking (with decent temps). 4.2ghz is target with stock BIOS settings (default voltage).

-0.005v to -0.004v is an increase...since the voltage is not dropping as low...cpu voltage will be slightly higher at -0.004.

Yeah I think you can skip around a little..no real harm as long as you don't set cpu voltage extremely high or cause overheating.. There is no need to find stability ever 100mhz increase...but maybe just make sure you can boot into windows at 4.2, 4.3, 4.4, and at 4.5 than start testing for stability. Someone correct me if I am wrong...

Thank you, malik86.

I tried the undervolting method but it failed to boot windows (vista home premium 64). RIght now, I'm at x37 using the incremental method.

I do have another question regarding Core Voltage and LLC. In the guide, it says to choose between LLC2 or LL3 depending on which is closer to the BIOS vCore. My guess is the Core Voltage displayed in CPU-Z is the actual voltage but where or how do I find out the BIOS voltage? Thanks for the time.

i would at least run IBT a couple runs or prime for 5-10 mins to make sure you dont instant BSOD at load tongue.gif but i agree, theres really no need to test for 12+ hr every tweak you do

here you go malikq? I don't know if I did this right or anything... lol it wouldn't let me run it in maximum for some reason... said cannot use all RAM or something

but anyways, how am I doing? smile.gif

oh and btw, temps never touched 70C smile.gifthumb.gif

Oh its a i5 2500k smile.gif still quite nice though, you should be able to get that stable at 4.8 ish without too much issues smile.gif

yeah right now it's stable at 4.5 smile.gif

Great guide and thread. Good hardware user friendly too. It's my first time to overclock a cpu and I didn't break something in the process.

I followed everything in the first post except I didn't touch on the DRAM Configuration menu/settings. I first used the undervolting method, which is offset to -0.005 and multiplier to 45, but it hanged during the first vista loading screen. Then, I went on the starting off method with offset set to 0.005 starting with multiplier to x34. Prime95 blend went with errors and warnings up to x44. But, once I set the multiplier to x45, the same thing happened. It hanged on the first vista loading screen. I guessed it has something to do with offset so I increase it 0.010. Same thing. So I guess I was wrong.

If I'm happy with x44 right now, do I have to set any parameter? Or just leave the offset to 0.005 and all that was mentioned in the guide?

Another question, what was preventing the cpu on getting to x45?

My vcore and temps when I started with x34 are 1.21 and 54c max. On x44, it was 1.27 and 66c on 10 minutes of Prime95 blend. Right now, on over an hour with Prime95 blend, its 1.28 and 71c.

Thank you very much for the awesome help!
