I5 2500k - Gigabyte Z68XP-UD3P Overclocking

I just got this board/cpu combo and it works fine with 1 of my new sticks of Crucial Elite but sticking the other stick in even on its own makes the machine just cycle on and off, so i'm assuming that ram stick is faulty, since the other one works in any slot.
It's all running stock just now, although with cpu vcore voltage on auto it made it 1.39v lolz, stuck it at 1.2 for now manually, and not bothering overclocking till i get working ram!
Even at 1.39v @ stock it was only 20 odd across the 4 cores, gotta love water.

Try updating the bios. I had lots of power cycling until updating to the new beta bios and so far its been ok.
 
No idea the board is a pain for power recycling issues latest beta BIOS is meant to help and mine is better but its still a godawfull board to work with.
It does sound like faulty ram you have.
 
I just read this

I too was having this infinite post loop problem on my motherboard. What I finally realized, is when applying the xmp profile in the MB settings it says that the mem controller voltage goes up too, but after going into the voltage settings page and actually looking at the mem controller voltage the higher voltage is never applied . I manually set this to the xmp specified voltage and problem went away. no more post loop, no more random idle bsod.

It could well be the VTT/QPI voltage that's the problem, when set to auto it should use the voltages for the memory profile. However it doesn't and stays on about 1.050v or just over which is far to low. The kingston needs atleast 1.2v VTT/QPI, where'as the main volts still need to be set to your memory which I did anyway.

So look at your profile voltages for VTT and set them correctly not auto, usually it's about 1.2v vtt/qpi, i've set to 1.190v because it over volts slightly to 1.220v.

Will test the cold boot issue and see if it's fixed :)

Hopefully they will release a final bios. I don't see why not if this one is working ok. I flashed mine using the windows util and it worked perfect.
I have been doing some extensive fiddling today and not a cold boot in sight.
 
F7C is the worst bios i've ever used to get it working right with boot loops and a cold boot issue. The Bios still sets the VTT too low when set to AUTO and using xmp Profile 1, the vtt volts don't increase and have to be manually set. But with Bios F7C I had trouble even getting that far!

1. Made sure my bios was set to default settings and used my usb stick to flash to the new F7C.

2. I powered down the system as it told me too, took the psu cable out, pressed the power switch on the psu and system to clear out any left over voltage and also cleared the cmos.

3. Powered up the system and it instantly shut off with a cold boot issue, it did this again after that. So I took out the psu cable put it back in and tried again. I was able to get into Bios.

4. Set to Default settings and rebooted, It hung on the Bios logo so i hit the reset button. Apparently the reset button can cause awful boot loops which it did. It then ended up in a continues boot loop which never happened in any previous bios flash. I was finally able to get back into bios and again set it to default and then it worked.

5. As i was able to set it to default I then proceded to flash the backup bios.

6. Rebooted the system and back in bios it said failed on overclocked settings, even though I had not done any overclocking!. I also noticed again that the VTT voltage as still only at 1.056v when on auto with XMP profile 1.

7. Set my overclocked settings, set the voltages as they should be because VTT and Main memory voltage on Auto doesn't work I was able to get into windows.

I'm not the only one with this board that has either a continuous boot loop or a cold boot issue and before anyone says it's your overclock IT ISN'T. It can do it on default settings as I said in the earlier steps. I should not have to go through all these damn steps just to get the system to stop boot looping. The VTT/QPI issue needs to be fixed aswell.

My advice stick with F7B for now

Forgive the ignorance as I'm new at this, but I noticed the CPU Clock Ratio is only 33X, surely that means you're only running at 3.33Ghz?

No as i'm using INTEL BOOST TECH clocking, it boosts to 4.7ghz when needed :)

INTEL BOOST TECH [ ENABLED ]
RATIO 1 - 4 [ 47 ]

33X is the cpu default
