I5 2500k - Gigabyte Z68XP-UD3P Overclocking

Just been having a play today and found something. If I use the Hyper X Ram and set the voltage to 1.5v it will cold boot, If I set it to 1.6v it's fine and that's how I have been running for a few days now with no issues.
If I use the Corsair Vengeance LP Ram I can use 1.5v and it does not cold boot and seems to be fine although I have not done any extensive testing but the Hyper X at 1.5v fails upon a re-start or powering from cold.

???
 
:D :D

Back to the drawing board lol

No cold boot in two days, only thing i've done is increased the room temp before booting the system but again could be placebo!, need a weeks test atleast
 
EDIT : I think I was on F6 before when the cold boot issue started appearing, F7+ was flashed to try and fix the problem!

Wonder if the 1.30 board version comes with F5?

when you guys are saying cold are you literally refering to cold? I really don't think the temperature has anything to do with it, I've experienced coldbugs whilst using phase but the difference between a warm or cold house surely isn't going to affect it?

This sounds like cold boot as in boot from switched off.

Anyway, have any of you tried discharging the static from the board before starting it? I've had that cause me endless issues on an old DFI board, basically turn off the PSU switch then hold down the power button for a few seconds, you can often see the fans spins up temporarily with that much stores power in the PSU/board then when thats stopped it means its completely discharged.

Then flick the PSU back on and go from there.

Maybe this board is holding too much of a static charge which is why pulling the ATX cable/kettle plug/CMOS battery seems to fix it? That would be a problem as it would be hardware not BIOS related..

Anyway, I've had mine 2 months and it goes on and back off every day and sits switched off overnight, clocked to 4ghz but has been higher.

Had corsair vengeance in it and a couple of days ago put 8gb of the tactical tracer in there and never a boot issue? Weird.. I'm normally plagued by this sort of thing!
 
"Cold boot" means that the computer must be turned off then when it is turned back on it will "cold boot".Read more

warm-boot procedure usually does not go through the complete boot process; generally, it skips the power-on self test (POST) to save time

and Matt my system has the plugged turned off and taken out of the wall, I'll discharge any left over voltage like you said but i'm highly doubtful of that being the issue..

Clutching at straws comes to mind :p
 
yes thats what i took a cold boot to mean, ie booting from powered off rather than restarting but you said about warming a room up?

and yeah, it may well be clutching at straws but it was a very real straw that made a whole batch of s939 DFI boards very difficult to restart, so much so it put me off switching my pc off for ages.

I have disabled the internal graphics and no longer use HDD caching.
 
^ So the only differences are Internal Graphics, which is set to disable if a graphics card is in use and I'm using HDD Caching

ALSO Smart fan is disabled as I want them to run at max speed all the time :D
 
Interesting, thanks MOOGLEYS :)

Going to try disabling EXTREME MEMORY PROFILE X.M.P and will test, if it cold boots it's not that :)

One step at a time :)
