All it offers is "Offset mode", where I can tell it to do auto or +/- 50mV increments. Image below.

450

So maybe there is something that the pro3 gen3 is missing?

The manual for the Z68 pro3 gen3 also lacks any mention of fixed mode, or a load line calibration option.

That's pretty weak. I'm not in front of my own comp. at the moment but I'll check for you in the morning if someone else hasn't chimed in on this by then. thumb.gif

EDIT: Weird, I found this on some other person's Pro3 Gen3:
450
They have everything and for some reason, you don't. Did you update the BIOS?

If you have already updated your BIOS to version v1.2 here, then what you see is what you get.

Use offset mode like it says in my guide and try to get the best without the PLL Overvoltage and LLC. It will be tough but doable.

Editted the last two to tidy up.

Yes, I updated to 1.2 and the screenshot posted is dated before the 1.2 bios update was available, nearest I can figure is that they intentionally or accidentally removed those options in the update. I tried windows and instant flash bios update options just to rule out there being any oddness there.

For now, I've emailed ASrock about it, but their tech support is down until next month due to their newyear celebrations. My 4ghz overclock seems stable, the hottest I saw it get was 64c, and an average of 55c.

I need some tips/help with my OC. I was able to get it to 4.8GHz.... did 15 hours of Prime95. So I thought that it was pretty stable... BUT! i have an issue with the PC double starting after it's been off for a while. I will turn it on and 2 secs later, it will shutdown and start back up again. It will almost always end up at the blinking cursor and it won't boot up.

So I then cut the power and restart it again and it's fine. It happens every single time after it's been off for a while. If I restart it from windows or shutdown and start right after, it's fine. Anyone experience this?

I've tried offset and fixed voltage, setting different VTT and PLL voltages and nothing. I suspected my Ram, but have been able to do 5 runs of Memtest without any errors.

Any ideas?

I'm sorry you wasted so much time testing things before you came here. frown.gif

This issue is common among ASRock motherboards. Mine does it too sometimes. I'm not sure why it does it, but I know the motherboard is the culprit and that it is a common harmless issue.

Go back and put your settings the way you had them originally.

My suggestion would be to just change everything to Sleep mode that way your computer will turn off everything except the RAM (<1W of power usage) and save your OS to your RAM, and when you hit a key on your keyboard it will magically turn on instantly as if it never shut off. This should prevent you from experiencing the startup issue, and since you don't even have a internal PLL overvoltage option, you won't experience any Sleep issues either.

Well that both sucks and gives me relief that it's not something that is dying.

Now ANOTHER issue that I am having... is that several games will crash either when loading at the begining... loading in between levels... or when exiting. The worst is NFS The Run... which will crash and then I can kill it through the task manager, but will BSOD right after I kill it. It's usually that the driver has stopped working... with a 126 BSOD.

Any ideas on what could be causing this?

Hey all,

Just recently purchased my new rig. Loving it so far and having fun OCing it. Upgraded from a cheapy MSI board and Phenom II X3 720BE to this 2500k. Having trouble getting stable at 4.7GHz and want to push higher for fun but would like to leave it around 4.6-4.7 for daily use. After 15 mins prime 95 blend worker 4 gets an error. Help would be greatly appreciated. Thanks!
