    i7 6700k instability

    aeunexcore

      Hi, first of all, I would like to show you what I have on my system.

       

      CPU: i7 6700k

      Motherboard: Asus z170 Pro Gaming

      PSU: EVGA SuperNOVA 850w gold

      RAM: Corsair Vengeance LPX 2666MHz (2x8GB) Black

      GPU: MSI GeForce GTX980

       

      I am already desperate.  I kept on getting "CLOCK_WATCHDOG_TIMEOUT" and "WHEA_UNCORRECTABLE_ERROR" BSODs for the past two weeks on my computer since powering it up.  It's supposedly a newly built system using my SSD+HHD and GTX980 from my old AMD system.  I tried resetting the CMOS to see if that will fix my issue but unfortunately, it didn't.  I'm still getting some random freezes and reboots when i'm not doing anything heavy like gaming or stress testing.  It freezes randomly where the sounds get stuck and it throws a blue screen error of one of those that I mentioned above.  I already tried changing the first pair of DIMMs (Corsair Dominator Platinum 3000MHz 2x8GB) I had and i'm still getting some blue screens.  Everything is at stock speed with the only changes I did was to manually set the CPU voltage in my BIOS to 1.200v.  XMP is disabled as well.  I want to know if my CPU is the one that is deffective.  I've been spending so much time on trying to figure out what's wrong with my system.

          Hello aeunexcore:
           
          In this case in order to fix the problem the first thing to do will be to set the BIOS to default values, the fact that you change the voltage could be the reason why this problem is happening,
           
          Please try a BIOS update to the latest version of the board and also install the latest drivers, you can get them from the following link, you just need to choose the operating system:
           
          https://www.asus.com/Motherboards/Z170-PRO-GAMING/HelpDesk_Download/
           
          Also, please test the PC using just one memory stick, try this with all the sticks to rule out a possible memory problem.
           
          Do you have the option to use a different SSD or hard drive?
           
          For testing purposes please test the PC without the video card.
           
          Remember that the top speed for the memory is 2133MHz, is the memory RAM working at that speed?
           
           At this point it is hard to tell what might be the problem with the PC, could be the motherboard or could be the board, do you have the option to test the board with a different motherboard, or test your motherboard with a different processor?
           
          Maybe there is a PC repair store close to you where they might be able to do that for you.
           
          Any questions, please let me know.

            I am having the same issue.  I believe the cause on my 6700k is the CPU itself.  Troubleshooting below

             

            Receiving various BSOD crash errors.  Including clock watchdog timeout.

            Specs:

            Graphics Card: PNY 1080 GTX

            Mother Board: ASUS Maximus VII Hero

            RAM: Corsair dominator platinum DDR4 3000MHZ

            Power: 1200w Silent Pro Gold

             

            Troubleshooting:

            - Tested without video card still BSOD

            - Reset Board to factory defaults. Still BSOD

            - Swapped out Ram to known working ram in another machine and tried one stick.  Still recieving BSOD

            - Tried replacing each computer part out with a known working part.  Still received BSOD until switching I7 with a known working CPU.  BSOD then stopped occuring.

            - Tested faulty I7 in another known working machine and BSOD started to occur in known working machine.

             

             

            Tried doing a warranty replacement but the system appears to be down

                  I have the same problem, also I did lots of tests. My PC is completely new ... I have replaced the GPU, PSU, RAM Motherbourd I always make the same mistake (Whea_Uncorrectable_Error).
                  I got an improvement by changing the value of the Vcore.
                  I think it's faulty CPU (i7-6700K) I asked the replacement. As soon as I will update. Greetings to all

                    Thank you very much for letting us know that information.
                     
                    Yes, after swapping all those parts, and trying the troubleshoot steps recommended above, if the problem remains then it seems to be a problem with the processor itself.
                     
                    The processor has 3 years of warranty, if you are interested in the replacement, please get in contact directly with us through chat, email, phone or online support, you just need to select processor on product type and you will get those options:

                        I just sent mine yesterday to get replaced.  If I remember correctly, it will take 2-3 weeks until you get the replacement part after they received the one you wanted to get replaced.

                            Hello there,

                             

                            Even though it is a little bit ridiculous, but would you please or have chances to have a try on motherboard rather than ASUS? I guess that might be some problems occur from the compatibility problems arose by firmware, special features, even though it is listed in the their supported processor list.

                             

                            Best Regards,

                            Aaron Janagewen

                              I replaced the Asus motherboard Gigabyte ... I replaced power supply, RAM, video card (all new) updated bios. always I get the same error. I Posted processor to the retailer. I will keep you informed as soon as I get a replacement. Thanks for everything

                                  Got the new i7-6700k processor, installed ... the PC is working perfectly. I'm overjoyed. I confirm that it was the failed CPU. Disappeared entirely the fault. Thank you all for the support.
