    Intel i5 6600K random lockup Freeze or BSOD...

    sahafiec

      Hi to all!

       

      firstly here is my configuration:
      Intel i5 6600k at stock speeds

      Asus Z170 ROG VIII Gene (latest bios 1504)

      Corsair DDR4 16GB (2x8GB) 2400MHz (CMK16GX4M2A2400C14)

      EVGA GTX980 SC (at stock speed)

       

      I am experiencing random system freezes and BSODs. The screen locks up and the sound is stuck or it is just BSOD.

      I already started a thread over at Tenforums and did a lot of troubleshooting but nothing really helped.

      most of the time the issue happens while just browsing the internet, playing some flashgame in the browser etc.

      it can randomly happen with listening to music with wmp or aimp or just while starting a portable application from usb drive.

      it's really very random and unpredictable, that makes it very difficult to analyze - but the issue is there in the background all the time.

       

      I'm running Windows 10 Pro and have the all the latest bios and drivers installed.

      there is no manual overclock except the ram running on XMP profile at 2400MHz (instead of 2133Mhz).

       

      how is it possible that Intel's Skylake can not handle ram at 2400MHz while Z170 chipset advertises speeds at >3000MHz.

       

      Thank you in advance for the help and advices,

      Sahin

          Hi,

           

          From what I saw on asus website, they have a firmware update for that asmedia controller.

          It is not enough to disable Asmedia usb in bios, You need to remove the drivers if there is a problem with them.

          I have ddr4 3200 and I have no problem with it. Only problem is the video drivers. Intel support team is working hard I think for those drivers as it seems they have a lot of problems.

          So there is no problem with the high speed. Your Ram speed is low compared to mine.

          First of all if you have a intel hd 530 igp enabled, uninstall all drivers and then disable it in bios. Then check if you still have same problems.

          If problem still persist try change video drivers, try older or newer drivers because from what i saw there are some buggy drivers for some nvidia cards.

          Also there is a possibility that a driver from an external device that you install to create problems on your system.

          If you can't fix the problem, there may be a problem with the cpu and the way your cooler is mounted on it. There are lots of posts on internet about fragility of new skylake cpus. People managed to damage the cpu because the mounting system of the cooler they mounted on it had no springs and they screwed it to tight.

          I hope some of these advices will help you to fix the problem.

          All i can do is wishing you good luck in finding it

            Hi Ronin,

             

            thanks for the fast reply and the suggestions.

             

            prior to disabling the ASMedia controller in the bios I uninstalled the driver under Windows 10.

            I suspected the driver as causing the issues but it was not that.

             

            furthermore I have never used the iGPU, it's disabled in the bios and I never installed driver for that.

            I always use my PCIE video card from the beginning on, driver version did not have much (if any) impact on the issue.

            no matter that I always use the latest, inbstalling only the driver and Physx as a clean install.

             

            I'm using a CM Hyper 212 EVO and I payed attention not to screw it too tight.

            I can even rotate the cooler slightly so it doesn't apply too much pressure on the cpu.

             

            on one side there are plenty of guys like you using ram >3000MHz with no issue.

            on the other hand there are a lot of user failing even at SPD settings.

            and some people like me get troubles as soon as they enable XMP.

            but we all have something in common: Skylake cpu and chipset - the rams doesn't really seem to matter much.

             

            after reading some other threads I'm almost sure I have the same issue, just not as severe as some others.

            Asus Z170 Gene strange memory issues...

              Try to increase voltages on PCH+1.0V to 1.110, VCCIO to 1.115, VCCSA to 1.25, and check if the Memory voltage is correct. All those voltages are connected to system stability when the memory is overclocked or with tight timings.

              These voltages I think should be enough for DDR4 2600.

                I've been through all that stuff many times Ronin, I've been troubleshooting for months.

                it came out that no driver is causing an issue and my rams are also failure free.

                 

                while some actions increased stability a bit there doesn't seem to be a permanent solution.

                this leads me to the Skylake C-State problem mentioned in lots of threads.

                the symptoms are almost same as mines...

                  Your RAM model isn't listed in ASUS' QVL for your mainboard, so you can't expect it to work flawlessly (if at all).

                  Try a supported model and check if the problem persists.

                    all the troubleshooting described in the threads above was done with the ram CMK16GX4M4A2400C14 (4x4GB), which is on the Asus QVL list.

                    after finding no solution and suspecting the ram I switched to the CMK16GX2M4A2400C14 (2x8GB).

                    although I have less issues now the main problem is not gone, it's just more random than before.

                    that made me think I was facing at least two issues rather than one, if one was the ram the second one seems to be the Skylake C-States.

                    at least that's my status today...

                      One thing I've observed with several Z170 chipset-based systems is, they can be VERY picky when it comes to RAM.

                      I've even had a case where a RAM model listed in the board manufacturer's QVL caused a freezing scenario just like the one you (and many others) are facing, although every RAM test I conducted didn't indicate any error, with the sole exception of a few errors in MemTest86+'s test 13 (Rowhammer; < 10 errors over a period of ~ 5 hrs).

                      In this particular case, switching to a different RAM brand / model fixed it. But to obtain that insight was a painful odyssey of trial & error on both hardware and software level.

                        I agree completely and I even would do it if I owned a ram store myself.

                         

                        Skylake is definitely very picky regarding ram, that's why I originally bought a ram suggested in both QVL lists, Asus and Corsair.

                        but even that did not help at all as I see now, my current ram (not in QVL) performans better than the first one.


                        I tested the ram over 9 hours with zero errors (MemTest86+), run Windows Driver Verifier over 72 hours etc. (both more than once)

                        it is an issue that is very difficult to troubleshoot for me as it's random and the only way for me to provoke it a bit is using XMP.

                        even then it may take a week to happen, but one day it will happen for sure. that's really annoying and disturbing to know.

                         

                        for me stability is much more important than performance, that's why I bought ram just one step over SPD speeds.

                          My only problem is with internet explorer. Is the only one that gives me some kind of errors, but I searched over internet and those errors are from graphic driver ...  It seems that there is some kind of memory leak in driver and when there are many pictures, videos on a webpage in ie, in a certain scenario it crashes. This happens all times on facebook when scrolling down thru all those pictures and videos, but only in IE.

                          On other applicatios or games it is strange but is all ok, well with the exceptions of the games that the driver is not optimized for.

                          I tested with a discrete graphic card, and those errors are gone ...

                          I will buy a video card as soon as the new generation comes out (hope they are ok and don't get me into more troubles).

                          Only way that I can get a blue screen is if the voltages are not set correct when using XMP.

                            My system is on Asrock Z170 Extreme 7+ and i7 6700k, and Corsair 2x8 GB 3200 CMK16GX4M2B3200C16R which is not even specified on asrock memory support list but is working.

                            Only problem was with the first bios. When I was setting memory on XMP system was not even booting. That's when I started experimenting with voltages.

                            On the next bioses they fixed the problem, and with default settings and xmp I didn't have any issues except those I described in the previous post.

                            At the moment I have set voltages manually because I saw that the voltages that are set by the mainboard do not correspond with the ones I see in HWinfo ...

                              actually they all should work as long as they stick to Intel's XMP design rules and specifications.

                              but what if Intel is the actual trouble cause?!

                                  Hi Esteban,

                                  In my previous posts I already included the link to my thread on Tenforums regarding the BSODs.

                                  I'm regularly updating the thread as soon as there is something to report, there are also test results and log files included.

                                  Recently I mostly got the "IRQ_NOT_LESS_OR_EQUAL" and the very last one being of type "MEMORY_MANAGEMENT".

                                  The only thing I didn't try out yet that can think of is to apply higher vcore on the cpu, keeping the frequency on stock level.

                                  I'm not sure if it would help, but something for sure makes my system loose stability at one point and it's not the ram.

                                  It is the second ram kit I have similar issues with so I think ram could be eliminated as a cause.

                                    From what I see in the last HWinfo u posted (I recommend update it), I think VCCSA is low for DDR4 2400. Also I don't see VCCIO.

                                    And CPU OC PLL is on auto or u decreased voltage ? On my mainboard I didn't even touched that voltage, and I think normally should be 0.950 if I am not wrong.

                                    VCCSA and VCCIO are crucial for memory stability if you use XMP.

                                    VCCPRIM 1.0 I think is PCH +1.0 on my HWinfo. That one should have increase voltage also and I see that you have it on standard voltage...

                                    It seems that either your mainboard is not setting correct voltages for the memory you have, or you have set manually wrong voltages.

                                    Please do a bios reset, and update HWinfo.

                                    Your memory has low timings I think on XMP settings and needs more voltage on those points.

                                    And stop checking your hdd. Your system has stability problems mainly from wrong voltages
