I5 2500k - Gigabyte Z68XP-UD3P Overclocking

"The core hardware architecture of Intel Active Management Technology (Intel AMT) is resident in firmware. The micro-controller within the chipset's graphics and memory controller (MCH) hub houses the Management Engine (ME) firmware, which implements various services on behalf of management applications. Additionally, flash memory houses system BIOS, code used by the management engine, and a third-party data store (3PDS) that enables applications to store information as needed in non-volatile memory."

Hmm so even though the PLL overvoltage on Disabled cured it for me, it's now on enabled :D :D, they think it was memory related because of a bad firmware or old out of date. No wonder people had trouble even when swapped to other brands!
 
I'm at 4.6GHZ for now completely stable, 4.7GHZ is also stable however i've dropped to 4.6 for lower volts and temps. No noticable difference in games ;)
 
Hmm well F7e is your best bet however, for 4.8ghz you'll need atleast 1.4v+ some have had to have it at 1.425 for 4.8 but this is upto you and i'll not be responsible for any damage to your cpu ;). Oh and use Intel Burn test LATEST version, if your system is stable with intel burn test that's far better than prime. Make sure your temps don't go over 77 in Intel Burn Test. Run 10 loops standard - high - Very high ( temps will be higher with IBT!)
 
Still to high that's some 4C above me and only 4.5 :(

I've got to 4.7GHZ at only 79C MAX intel burn test, generally though it's 76 and much lower in prime
 
Had two cold boots yesterday first time since last month over 20 days!, however on checking gigabyte they've removed the bios as faulty and gone back to F6!

Seem to be having a slight problem with mine. When in windows my computer is completely stable, stays at good temps and have run a burn in test for 2 hours on max settings.

Just seems that sometimes when I go to turn my computer on in the mornings it will occasionally not cold boot (Switches off mid turning on and then display's a message saying it failed to boot which may be due to overclocking) for no apparent reason seeing as I have already determined it is stable by running tests.

This is a common problem i'm afraid with gigabyte Z68/P67 boards, here's a tip!. When it shut's off on it's own as you boot up, pull the psu cable out for 1sec and put it back in. It should automaticly boot up on it's own and not shut off while staying stable. On the rare occasion it does it again, pull that psu cable out.

There is the odd member here who blame everything other than the board or bios just ignore em, gigabyte know it's an issue and have put out lots of beta bios's trying to fix it.

Also Neil when you had your cold boot issues previously when the system would shut off while booting then start fine after did you get a message about overclocking settings when it happend. I get this problem but am yet to try the new bios (F7)/also the PLL overcoltage fix

Thanks

I did with the previous beta yes but not with F7E, however if I do get any cold boots I just pull the psu cable out when it shuts off then put it back in. I've only had one or two cold boots in over a month which is fine with me :)
 
It was down to a firmware issue on the chipset, thus because the computer shut itself off it detects that it was an overclock problem which it wasn't, you could get it at default settings too :(. However even if you update to F7 the new bios you still may get a cold boot at some point. But what ever you do don't let it restart on it's own straight away just pull that psu cable out and put it back in then let it boot.

Oh and back up the other bios too when it's all started up correctly after flashing! :D
