Sometimes when I boot into the bios. It freezes. I mean it literally freezes in bios even when not overclocked.

My CPU is now stable at 4.0Ghz but I want it likes 4.4Ghz. But even when i set the automatic OC preset to 4.2Ghz and run Prime95 it freezes the very moment on stress. Why is that? Do I need to manually play will the settings and how? All I know is the preset settings that it will automatically adjust everything Clock and Volts.

Someone own a Asrock Z87 Pro 3 out there that could enlighten me? I want my CPU clocked higher since I get temps on speed fan not exceeding 25 degrees..

P.S.: I have an Hyper 212 Evo plus and a NT-H1 thermal paste that was used into it.

Your oc is not stable. I do not recommend using auto oc software. It typically helps you run a stable oc but at the cost of overheating. Learn your chip. Manually overclocking takes more time but you get so much more out of it. Here's a good place to start learning about your type of board:

I will see if I can find a detailed step by step guide but that's something you can google in the mean time as well. It's not as simple as inputting what others have done. You have to be methodical and be willing to take the time to refine slowly and surely. Once all is set you must simply use your system as you typically would...

You have to be methodical and be willing to take the time to refine slowly and surely. Once all is set you must simply use your system as you typically would day to day and it may be 1 week or 1 month in when you try to play a game, update bios, etc where you find that another setting must be changed to be more stable. This includes scaling back your oc to increasing your vcore or llc. As you study and try it will make more sense.

I will update this post as I find you more info. Hope this at least helps you get going in the right direction. Remember if you aren't patient then overclocking may just not be for you. I would then recommend going to default settings so you can at least have a working computer.

UPDATE: I'm having trouble finding a guide specific to your motherboard. Here's a general quick guidline.

Your terminology may differ but when you go into your bios try starting here:

Note: For you since your cpu is freezing set to optimize defaults first before trying this. If you have to reset bios you can jump cmos (this is as simple as removing the coin looking battery for 1min and replacing). Once your computer and mobo are set back to factory default the freezing at bios etc should stop and you can now perform the following to start learning your chip:

(terminology extracted and adapted from Asus and may be labeled differently)
Ai Overclock Tuner ► Manual

BCLK/PEG Frequency ► 100.0

AsRock MultiCore Enhancement ► Disabled

Turbo Ratio ► Manual

Ratio Synchronizing Control ► Enabled

1-Core Ratio Limit ► Desired Overclock (42 = 4.2GHz or 45 = 4.5GHz for example)

Internal PLL Overvoltage ► Enabled (Disabled if you want to keep Sleep Mode)

Memory Frequency ► Your rated RAM frequency

EPU Power Saving Mode ► Disabled

CPU Voltage ► Manual Mode

CPU Manual Voltage ► 1.2000 (The image indicates a certain voltage, do NOT assume this voltage will work with your chip!) All chips require different voltages for every clock! Even stock, chips vary in the voltage needed to run that!)

CPU C6 Report ► Disabled

Package C State Support ► Disabled

If you take the time and do all this you will know much better how your chip behaves. If it feels uneasy that's normal because this is all brand new to you. Just remember you can always put everything back to default. The tricky part is being methodical and patient to see what works for your chip.

Here's the actual guide to a different board/chip that I derived this from:

http://www.overclock.net/t/1291703/ivy-bridge-overclocking-guide-asus-motherboards

All the concepts apply the same. If you can find a better guide that's actually asrock and better yet your same exact board then by all means...

Until then I wanted to give you a quick list to reference so you have an idea what to try. I empathize you not being able to use your rig. Again, hope this all helps!

Thanks,

Justin S.

UPDATE2:

Here's a link to a haswell asrock guide:

http://www.overclock.net/t/1411077/haswell-overclocking-guide-with-statistics

I'm off to take care of some personal business and don't have the time to review that but I glanced at it and you may want to try it instead if it makes you more comfortable. Have fun!

Could you still help me on this? I saw a guy post with an ASRock mobo but the higher end the Extereme6 and has 4770k he hits failure at 4.2Ghz using the preset althought he didnt mention a freeze but still we almost are in the same scenario.

Could you help me walk through this overclocking thingy? I ma very new to this and I thought its easy as clicking a button. I didnt know its like cooking where you need the right ingredients to get the perfect taste.

First, keep it simple, just shoot for a modest oc and see if you can learn how to make that stable. If successful, watch the temps to gauge what it will take to get a higher oc.

Also, did you put it back to default or not yet first?

In any event, so, shoot for say 4.2 Ghz. Set the vcore a little high (temps will be too but it will be more stable) to something like 1.25V. You may need more or less but we don't know at this point. If you have a poor oc chip you may even need 1.3V but maybe you have a good chip and it needs only 1.1V. We don't know yet so start in the middle at 1.25V.

Keep all else auto and see if your system runs without hanging, crashing, bsod etc. Now, stress test it lightly. What I mean by this is download intel burn test and run on standard mode and be ready to click stop if your temps shoot past 90c at all (100c is way too high and your chip may start to throttle which isn't harmful but not good and gets too close to burning your chip; throttling is there to prevent chip burn but you obviously don't want to be there). If your temps stay below 80c then you have an ok chip for this oc. If they are shooting past it you will need to learn how to play with the other settings more carefully to get this under control and your chip isn't great for oc but at least works for this oc.

To keep it simple that's all your homework for now. Before turning this into a 6 page tutorial please read up where you can on some of the basics. It may be that something else is causing issues rather than instability on the oc only. However you haven't communicated anything to indicate otherwise so we'll start here for now.

If it works then we'll talk about how we can start stepping things down for the same oc and lower our temps. Once stable then you can contemplate what it will take to increase the oc and will be much more knowledgeable at this point. Until then just get this first part going.

If it isn't working then we have to go even lower and you just have a really weak oc chip unless again it's some other unstated problem with your system (ram, mobo, psu, gpu, drivers, bios update needed etc.) Speaking of which make sure your bios is up to date if you haven't already. When I first started, overlooking this and then doing it made a world of difference.
