    Unhappy ASRock X79 Extreme 4 Rebooting when under stress

    Hi all I have a new build computer which when I play games or run a stress test the computer will reboot after 20 minutes (But runs perfectly fine with normal browsing etc). I use furmark for GPU stress testing, I am currently running Memtest86+ to check RAM then I will be using Prime95 to test CPU. So far the only information I can provide is

    Please bear in Mind I upgraded from a Intel Corei7 920D, Gigabyte X58-UD3R Using all but the RAM below and didnt have problems

    Case: Corsair Graphite Series 600T (2x200mm Fans and 120mm rear fan)
    Mainboard: Asus X79 Extreme 4 (Bios 2.10) All drivers installed from Disk
    CPU: Intel 3820 Core i7 3.6ghz (Stock Clock with Aftermarket Cooler)
    Graphics: XFX Radeon HD5970X2 Black Edition (with Arctic Cooling Accelero Extreme Kit, 12.8 drivers with Manual Fan control @ 100%)
    PSU: OCX Extreme Gamer 850watt
    GFX: G.Skill 1600mhz DDR3 (16GB) Quad Channel Kit
    HDD: OCZ Vertex 3 120GB, Samsung 1TB x2 RAID0

    Tests Carried Out
    FurMark : Random Crashing (With Case Sides On)
    FurMark : Fine (With Case Sides Off)
    Prime95 : No Errors
    FurMark + Prime95 : Fine (With Case Sides Off)
    Memtest86+ : Passed
    ATi Clock Test : Passed
    3D Mark : Passed
    3D Mark DX11 Stress Test : Passed



    Temps whilst testing

    CPU MAX Temp :72'c
    GPU 1 MAX Temp :68'c
    GPU 2 MAX Temp :65'c
    Mainboard MAX Temp: 46'c


    Any ideas? Thanks guys

    Don't know what the problem is really ...

    As you said, only crashes under Furmark with case closed.

    Bad ventilation or bad VGA cooler (needs reseating?), etc.

    Which Prime95 tests were run and for how long?
    Have you checked windows Event Viewer to see if there are any problems shortly before each reboot?
    Were there any BSOD's just before your system rebooted?
    Have you disabled auto reboot when a BSOD happens?
    Where are the 200mm fans mounted?
    What is the setup for each fan? Intake? Exhaust?
    Can you test with another power supply?
    Can you temporarily install an internal cooling fan provide better cooling for your video cards?

    Repeat your case closed tests with only one video card installed.
    If there are no problems, remove the installed video card and test with the other video card.
    If there are no errors with both single card tests, underclock both cards by ~10% - 15% to see if this helps.

    Many Thanks for your comments. Strange thing it seems to be working now. I moved the GFX card to the top PCI-E slot, I've plugged in the additional X-Fire power to the mainboard and used 2 power rails to power the gfx card instead of 1. I have the sides on the case atm. So far I played 4 games approx 30-40 minutes a session and seems fine.

    Answers to the questions

    Which Prime95 tests were run and for how long?
    I just clicked on File then Start and it auto sets all cores and maxes all to 100%
    Have you checked windows Event Viewer to see if there are any problems shortly before each reboot?
    All that is shown in the event log is loss of power un scheduled reboot occurred
    Were there any BSOD's just before your system rebooted?
    No BSOD. The whole system including the power supply shut down. Then all came back on like a first time boot.
    Have you disabled auto reboot when a BSOD happens?
    Not tried this yet. Will set it when I go home tonight.
    Where are the 200mm fans mounted?
    I have 1 on the top of the case acting as an exhaust, and 1 at the front of the case as an Intake.
    What is the setup for each fan? Intake? Exhaust?
    I have 2 exhaust fans which are 200mm at the top of the case, the 120mm at the very back of the case next to the I/O panel.
    I have 1 200mm fan at the front as an intake.
    I have made my own fan for outside of the case which are 1 120mm with 2x 80mm blowing the air away from the top of the case so no heat builds up.

    Can you test with another power supply?
    I dont have a spare at the moment, but it works fine with my old main board.
    Can you temporarily install an internal cooling fan provide better cooling for your video cards?
    I dont have any spare fans, but my arctic cooling kit has 3 hi rpm fans working at 100% keeping the GPU at 39'C at idle 77'C at 100% load on both GPUs

    It looks like your power supply's OCP (Over Current Protection) kicked in to quickly shut down the psu and system to prevent too much current being used by the limited power delivery system's capacity to your video cards. Your system is probably OK now that you are providing additional needed power via the motherboard power connector.

    Sorry for the complex wording, it's been a very long day.

    Any ideas? Thanks guys
    i was just having this problem with my asrock extreme 6.. i fixed it by putting the SB fan on level 3 speed.. im not sure if you have a south bridge with a fan on the extreme 4 but check in your ASRockAXTU program to see if the SB fan is even on.. if not turn it to whatever level you want.. level 3 is about 2600 rpm.. I hope this helps, it helped me
