    WHEA error - looks it's CPU-related

    rado77

      Hi guys,

       

      so after today's hard googling I found some infos where WHEA issue with Skylake CPUs were related to CPU directly. As my suggestions here - for a while helps to poeple disabling 1 CPU core. By disabling 1 core system doesn't show WHEA error for some "unknown" time. User is also able to install new OS without freezings, bluescreens and so on. But this solution is only temporary.

      But - people solved WHEA error by replacing CPU. We (NUC-guys) cannot do it because CPU is soldered on motherboard. But it really looks that WHEA is caused by some CPU internal damage, but not by any component on motherboard

          Wow !!!

           

          If this is the case, this is huge .....

           

          Was the info CPU specific or did it refer to i3's and i5's ?

           

          We really need INTEL to comment on this !!

           

          What was the source of the info Rado?

            I found that info on 2 or 3 different forums. And WHEA was allways solved by replacing CPU Skylake- desktop processors. And also by my recommendation - when 1 or 2 WHEA-guys disabled 2nd core in BIOS, their NUC was working without WHEA error next 2-3 days. After that time the same issue so it affects also 1st core

             

            But the question is: what damaged CPU? CPU itself? Or something outside CPU = something on motherboard? So what's bad? Please vote :-)

            1, CPU

            2, CPU and something on MB

            3, something on MB

             

            :-)

              hehehe, you forgot:

              4. something in front of the NUC

               

               

              no, just a joke, nice find out... because of 2./3. if the one who have to replace the CPU uses different motherboards, then we could be sure it's 1.

                Yes, they had different MBs. I don't know exact manufacturers, but in 1 case it was Gigabyte. But I don't think it's directly Skylake's problem...those were desktop CPUs, not mobile CPUs. I think that these CPUs are used in many notebooks without problem. So it must be problem on board, but it probably destroy also CPU (because it worked ok few days on 1 core...)

                 

                So situation is like this:

                1, something broke on motherboard

                2, it destroys something in CPU

                3, CPU displays WHEA error (not because damaged component on board, but because of own internal damage)

                *that component on motherboard maybe isn't damaged completely, it can be damaged only partialy. And I have feeling that it have something to do with voltage/powering core(s), Maybe when it fails, it sends too high voltage to CPU and burn something inside CPU... but this is really question for Intel

                  Sorry, I’m not sure about this… I have to ask what’s about some issue at some Skylake CPU like this http://www.pcworld.com/article/3021023/hardware/how-to-test-your-pc-for-the-skylake-bug.html (btw: I done the test for 3 hours at my NUC6i5 without any problem)… I don’t know about which kind of Skylake CPU you're talking at post #1 (it doesn’t sounds like NB soc’s if you talk about MB from Gigabyte at post #4)… maybe Intel have a problem with 14-nm-FinFET ? It wouldn’t be the first CPU from Intel with problems…

                  e.g.

                  https://en.wikipedia.org/wiki/Pentium_FDIV_bug

                  or chip-set http://www.notebookcheck.net/Intel-s-defective-Sandy-Bridge-Chipsets-Status-Report.45596.0.html

                  and one more argument is, that they replaced the CPU and everything is fine (of course you could be right and a problem “outside” of the CPU, after a while, damage the CPU (like a bad chip-set ))…

                    But that's different problem. All Skylakes had problem with that bug. I ran Prime95 long time and without issue. That's other thing that WHEA issue. I think we have solved it in some of BIOS-es (I don;t know in which). I wrote that people solved WHEA_UNCORRECTABLE_ERROR boot loop by replacing CPU. If they received WHEA again after some time...I don't know. Maybe yes

                      Chip failure suicide or murder?  Chip or no some component is being murdered.
