Overclocking Overclocking problem

I recently got my overclock stable on my i7-2600k at 4.2ghz and 1.28v. It passed prime for 10 hours so I stopped it and shut the computer down and went to bed. I turned it back on a few days later and I was greeted by this wonderful message

This seems to happen every time I OC. It works for a while, and then this happens, the mobo loads the default settings, and I have to start all over.
My mobo is a GIGABYTE GA-Z68X-UD3H-B3, and if there is any other info I could provide that would help just let me know, im at work atm and will be off in a couple hours, so it might take a while

 

Just a point, I've OC'd my 2600 to 4.2GHz by just turning up the multiplier value and it's been completely fine if thats as far as you wanna take it..

 

may b add a Little to QPI/vtt voltage as i think stock is 1.050v so manually set it as u have 16GB ram it may help with stability
also update bios to newest and back up bios helps with stability

I got an error like that when my CMOS battery died with my old mobo. If overclock is stable in windows you could try replacing the battery to see if it helps.

 

Its a common problem with gigabyte boards. Mine does it when not overclocked

 

I've seen errors at just over 23 hours and wouldn't call a system stable until it had at least reached 24. On the other hand if your system is only on for 10 hours at a time then it may be acceptable.

 

Its a common problem with gigabyte boards. wont use them for overclocking anymore

 

Yeah, this is what I've heard, especially with my board in particular. Wish I would have known about this site before I bought all the parts. Ha

 

FWIW, I dont think my computer is on for even 4 hours at a time these days lol

 

Latest bios?

 

Thats my problem. I had it at 4.2 for a while and thats when this happened the first time, about 2 months ago i believe. Ive also tried 4 even and 4.5 and the same thing keeps happening

 

I will be updating the bios later today to see if that helps at all, i just have to find my usb stick lol

 

Apparently the issue has been ironed with for z77

 

Double check the pins on the socket are not bent as this has been known to cause these probs as well
