I5 2500k - Gigabyte Z68XP-UD3P Overclocking

I have now changed my RAM to Corsair Vengeance low profile 1.5V from Kingston Grey 1.65V and so far using F6 bios have not had any problems. I have done a few hours of fiddling and what usually would make the board cold boot has not.
Will give it a few days and see if it happens again. ??

I've got this mobo and I've had no problems at all. I've got my i5 2500k running at 4.8ghz stable @ 1.37v. It must be your CPU, I think 10% of overclocking is down to your mob and 90% of it is your CPU.

Hi there what is your settings on this mobo? After reading these forums and post I am really worried about the cold boot issue. Since you didn't have any and if you don't mind can you post us your settings?

Maybe the others have their settings set wrong somewhere.

lol ;) We don't have any wrong settings, Sgt Takleberry is way off just read this thread

p.s Haven't had a cold boot in two days now ;)

It just seems like that the cold boot is related to unstable overclocks.

And seeing your settings I find them a bit unstable just looking at it. Especially setting most of them on Auto.

You can never trust Auto.

I havn't done OC for a while but it just seems that the settings you have set in the first page seemed a bit hmm not based on much understading of what each and one of them does.

I remember the days when each settings had to be set and played around till we get the best OC.

If the settings are not correct then booting can be a problem and for Auto to kick in the right settings then you are going to be looping constantly and hoping for the best.

Having not overclocked this mother board due to the fear or cold boot. I have not had any issues so far shutting on and off, restart on and off to intsall a lot of software and updates.

If it is just a cold boot problem in genearal then I would have encountered it by now.

I am running on F6.

I will look further at the overclock settings for the i5 with this motherboard.

Bit of a small update from gigabyte -

p.s No cold boot in two days and YES the overclock is stable despite what hsiaolc thinks! :)

Its just the way I feel with experince. Not saying that you don't have any. But for OC systems to be stable usually I like to turn of EIST and C1E off completely. But you've left it at auto. I saw that a lot of people have used what you have posted and it is just my feeling that when the system is switching from off to on the setting is not stable enough.

Just like I was trying to OC today at 4.3 and all IBT passed with 20 loops and 20 min in on Prime 95 and all is fine but suddenly the screen went blank and I thought this is going to be bad.

Like I predicted it went to sleep mode because I forgot to change the setting in windows and what did it do? It went on a forever loop. But I was not worried or paniced and just press power switch till it turned off. Pull plug and reset comos and back to bios normally.

Went to windows and swtiched all those power saving mode off and 7 hours in Prime 95 still solid and I feel it is solid when I turn it off and on.

So when certain things left at hmmm Auto it is less desirable because you never know when it will turn on you.

But hey thats just my two cents and with so many using your temeplate I can't feel that they don't know what they are doing and showing up with an overclock screen at 1.045v. That is not really what it should be it is only at 1.045v because the cpu already stepped down and so did the voltage and people wonder why their oc is not working properly when they tunr it on and off.

People expect their OC to be done and dusted with just a change of multiplier and then the system will take care of itself. Well it doesn't work that way.
One did in this forum and he is using brute force of voltage to maintain his stablity.

I am at 4.3 with 1.265V applied to it. But still testing once I am 100% happy then I will post my settings. In the mean time, I dont' have cold boots etc and the ones that did happen it was my own fault to let go sleep or when playing around with the lowest Vcore possible.
 
It is true what you say about AUTO that you don't know if it's off or on but gigabyte assured me that when it's set to auto it's most likely ON unless it's been disabled. Auto = ON. As for the cold boots they are happening to people if it's at default or overclocked, some have it even on optimized bios settings. It's just so sporadic, but I did read that turning off the bios logo and quick boot is a better way about things.

Need more updates really

EDIT : I'll put them to ON just to be on the safe side, I want the cpu to downclock which it is doing which shows AUTO is working :D

I have just bought Gigabyte z68x-UD5 motherboard and after reading few threads regards to boot loop for cold boot issues i don't know if i have made right choice.

Is this problem common with all the gigabyte Z68 chip motherboards?
