P67A-UD5 issue! "The system has experienced boot failures because of overclock"

[diegodiniz]

Hey guys. I´m Brazilian and i dont speak english very well but i will try ok? Need your help!

My rig is:

i7 2600k
GA P67A-UD5
8GB Corsair Vengeance 8-8-8-24 (model CMZ8GX3M2A1600C8)
Corsair 75w TX
HD 5870
Noctua NH-U12p SE2

Im using the F6 BIOS from gigabyte. I dont have any problems with the overclock. I overclock the CPU to 4.2Ghz and i dont have BSOD´s. The over is rock solid but when I turn the power OFF or when I clean my PC...the BIOS show this message:


"The system has experienced boot failures because of overclocking or changes of voltages. Last settings in this page may not coincide with current H/W states."

After that..the system return to STOCK !!! That happen 3 times already! I dont know why this is happenning. My overclock is stable...my memory modules are OK. But the system always return to stock when i turn off the power of power supply. Can you guys please Help me???

PS1.: I try to use the new BIOS (F7) from the website but I get a lot of BSOD´s with it and i come back to the F6 BIOS.
Ps2.: I already put a new Lithium battery on the motherboard.(dont work)
Ps3.: I already make the BIOS SWAP...pressing CTRL + F12 to put the F6 BIOS instead F2. (dont work)

PLEASE HELP!

Hi and welcome to the Gigabyte Forum.

The first thing i would want to check is the memory. Please follow these instructions exactly.

I would suggest that you download and run the latest version of  Memtest86+ to check your RAM first.

Memtest86+        http://www.memtest.org/

Insert one stick of memory in slot 1 and run Memtest on it for at least 10 complete loops/cycles and if there are no errors then swap it over with the next one and continue untill you have checked all  modules.
 
If you have any errors the module is faulty.

If you have any faulty modules you will have to return the whole kit as they are matched.

Post back when you have done that with the results.

I already did these memory tests with NO ERRORS. Memory modules are OK. I see other guys with the same problem. This could be a  BIOS problem from gigabyte??? A new BIOS can solve this issue???

Look my memory specs at CPU-Z. Im using them at stock. 1600 cas 8-8-8-24

Try running the memory in DDR3_1 and DDR3_3 instead.

Try running the memory in DDR3_1 and DDR3_3 instead.

I cant..because the fans of Noctua dont let it happen. Only the 2nd and the 4th slots are available! Sorry for my bad english but..this is a memory trouble??? Only the memory can cause this issue or something else can cause this too

There are several things that can cause it but I am trying to elimate them as we go. The Noctua fan can be move upwards to give space for the DDR3_1 module to fit.
