Previous Overclock settings have failed

[SMR]

Hi,

 

2 weeks ago I decided I was overclocking my 4690K running on my MSI Gaming 5. Got it to 4.2 Ghz without problems at first and test benched it for 10/12 hours with intel tuning utility.

 

Then my system shut down on me while I was just doing.. almost nothing, like just browsing the interwebs.

 

Anyway, after that I "underclocked" it to 4.0Ghz (just so I can say I passed the 4.0 limit) and the same problem occurred  while the system was at idle. 

 

I also usually start my PC before leaving in the morning to access it via teamviewer during the day. But I noticed that this week it was offline for 2 days in a rows to discover after work that my overclocking settings have failed..

 

I am at work right now but i think I ran 4.2Ghz at 1.22V and I can't remember at what voltage I ran it at 4.0. I based my voltage on the spreadsheet found on the forum for the Haswell overclocking guide thread. 

 

What I don't understand is that my overclocks settings seems really safe, I mean 4Ghz for a CPU that have stock turbo set at 3.9 isn't high.. at all. 

 

Also, PC never shut down when I was gaming, rendering video or playing 1080p video.

 

I'm confused. 

 

What can it be ?

 

Thank you all .

Sometimes odd things can trigger a failure of an OC, you should try bumping your voltage and seeing if it continues to crash.

I have my i5 4690k at 4GHz at roughly 1.2v, somewhere near there, and mine is fine doing anything and never had a problem.

 

But as @Ostwind said, there are many things that could cause a overclock to fail and you dont know what it is.

what i would do is run stock and check if it turns off,maybe the OC isnt the issue D:

Hmm maybe mobo is picky on settings, will try to update BIOS version. Or at least check if there is an update and if it change anything significant.

I'll try to restore the OC settings to stock. I didn't have problem while not overclocked, but yeah i'll try.

Seems like a BIOS instability to me more than anything else. Update the BIOS and check again. I figure the problem will be solved.

Check stock settings.

 

Also, adaptive voltage can be to blame sometimes.

4GHz @ 1.2V? That's a bit high tbh.

Yes it will be my first step.

I ran adaptive voltage, what should I set if not this ?

 

I know I already thought about the voltage being too high but I can't remember if I lowered it, and now that I changed a couple of time I can't exactly say what voltage I was running at 4.2, but thank I'll keep that in mind.

Bios updated, passed from v1.0 to 1.9 lol Might explain why it was so instable. 2 days and counting without any interruption @ 4.0GHz
