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

[xfullboost]

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

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.

I set the VccIO to 1.175 on Friday (30th), the problem persisted. Next the twin packs of RAM where indeed mismatched on the dual channels, I put the same serial numbers on the same channel.

My computer seems better, it didnt instantly shut off for a day or two, but this morning it did it again.

The computer booted and loaded windows 7, 20 seconds letter it restarted itself without any warning.

Its still randomly doing instant shut downs. I don't know what the hell is going on.

Is their a program that can log what my computer is doing, so i can check that log after a shut down?

May I suggest that you do a full clean install of your OS. If it was hardware you would be getting a Microsoft error report each time your system rebooted saying your system has experienced a unexpected shut down, are you getting that message. If yes then there is an error report being generated. You are able to access that report.

Yes I am getting the message before windows boots stating my computer shut down improperly. I select the option to start windows as normal.

I'd be willing to do fresh install if we are confident it will fix the problem. I recently re-installed windows7 about 3 weeks ago.

I am viewing my error reporting. I cant make much sense of it, perhaps I can export it and have someone more experienced than I am take a look?

Please do provide the error report we might be able to help isolate what is causing the issue.

here is an archive of my windows event logs. uploaded to my asus webstorage account.

It looks like your NIC (Gigabit LAN) is the cause.

Remove your LAN cable and run your PC for a few days and see if the problem continues. Or swap out the LAN port you are using and try that.

OK, I switched to the other gigabit lan port. Im curious as to what you saw in the error report that lead you to that. Its all Chinese to me.

We'll see how she responds...

Its been fine for 2 days, and it just now shut off instantly. I was gaming for 4 hours, i then was streaming a tvshow on netflix while extracting a large zip file.

while i doubt that has anything to do with it, it will shut off randomly at any time, doing any task.



i doubt that has anything to d

The two incidents are not related. Your NIC was showing as the cause for many of the shut downs. Hence the two days of no problems once you had swapped NIC.

This latest shutdown is to do with thermal load. Basically you were doing two things that required huge amounts of CPU resource. CPU working hard = heat being produced. Your temps as 66 pointed out are not ideal.

Reseat your cooler and see if your temps improve.
