Maximus IV extreme-z z68 restarts instantly under load in a loop

Hello, this is my first post here. I stumbeled upon this site while searching for a solution to my problem.

Problem #1: Everything shuts off instantly after 10-15minutes of gaming or benchmarking. System reboots then....
Problem #2: Everything shuts off immediatly 5 seconds after the START button is pressed. This can repeat up to 4 times before finally posting and booting windows.

Nothing is overclocked. the only setting I changed was the ram speed to 1866mhz.

I've monitored my temperatures for my CPU and GPU's. Those three temps are well within normal. Under load CPU temp average between all cores is 59c. GPU1 is 80c GPU2 is 70c.

I really cant remember if I breadboarded the motherboard, I think I did but honestly I can't remember.

The last two instances happened after 10minutes of playing Arma 2 and Battlefield 3.

I would like to know if the motherboard could be causing this issue, or if its something else.

This computer was put together in January 2012.

System:
ASUS Maximus Extreme-Z Z68 (optimum default settings)
Intel i7 2700k stock clocked
Corsair Dominator GT 2gb x 4 DDR3 8-9-8-24 1.64v
Sapphire Radeon HD6970 with aftermarket air cooler (in lane 1) bridged crossfire-X
Sapphire Radeon HD6970 with aftermarket air cooler (in lane 4)
OCZ Vertex3 MAXIOPS 120gb
OCZ Vertex3 MAXIOPS 120gb in RAID
Windows 7 Home Premium 64bit
Single custom CPU water cooling loop.
PC Power&Cooling Silencer MK II 950w (89a on single rail)
Xigmatek Elysium case.

So if you have any ideas, anything at all, please leave a reply.


Thanks

Friend exactly the same happened to me when I changed the speed of memories
from AUTO to 1600MHz (which is the speed of the my memories)
Now read this, to see if it helps you solve the problem:

Hello

Well your system is overclocked of course, the DDR ram 🙂 And I would suggest that is where we should start looking for a possible cause.

Could you please download Memtest86+ ver 4.2 (There is a USB stick version) and run memtest on your ram.

Please post back once you have successfully completed two cycles of the Memtest

Cheers

Yes - go into BIOS and F5 enter
Then select the XMP Profile
F10 enter
Run Memetest and then report back once you have passed the test. 🙂

Memtest passed with flying colors.

Still sounds temperature related to me. Test the cards by only installing one at a time and doing some gaming. Inspect the motherboard for loose heatsinks. Use a temperature monitor that will give you readings on individual cores to see if any of the cores is substantially hotter than another.

Core0 - 60c
Core1 - 68c
Core2 - 70c
Core3 - 67c

CPU - 62c
CPU Socket - 44c
Motherboard - 30c

My computer seemingly shuts off completely randomly. So mImageaking changes one a time takes awhile to know if it changed anything.

70'C and you are on water loop and no OC ? Something is wrong for sure, what kind of Water cooling you have ?

The sticks are 1.65V, so make sure VccIO is at least 1.175V (1.175V might work better than 1.2V). 1.65V is not the best for Sandy.
Also you are using 2 twin packs, so don't get them mixed up and try your PC with just one set installed.
