    WHEA Errors on Skylake NUCs NUC6i5SYK/H and NUC6i3SYK/H

    cvare

      Just to keep consistent, I'm going to point this to the FAQ, here.

          Hi cvare,

           

          Good to know this issue is being investigated. I have two SKL NUCs and luckily am not affected (but I did downgrade to 0028 after noticing the fan issue and always kept an eye on temps). But I have a suggestion: Why not collect the failing NUCs from all the people who have reported problems (and send them replacements)? This way you'd have a nice sample size and don't need to try to recreate the problem. You could then have the NUCs analyzed. Some may have failed due to overheating (fan issue which I reported first, over a month ago), some may have other issues.

           

          Best regards,

          Stefan

            Hi Cvare,


            Bought my machine about 10 days ago, and after several days started this WHEA_UNCORRECTABLE_ERROR to appear.

            My machine spec is NUC6i5SYH having:

            2 X Corsair 8GB DDR4 2133Mhz CL15 SODIMM

            1 X Transcend MTS800 TS128GMTS800 128GB SSD M.2 2280 SATA

            1 X Western Digital Scorpio Blue WD5000LPCX 500GB 5400RPM

            I'm running Windows 10 Pro 64bit, but the problem exists (on my machine) also with Win 8.1 Pro x64.

             

            I updated the BIOS to 0036, it seems that it fixed the fan issue and the temp stays well under 50C (with the error it reached 85), but without any success about the WHEA error, it really annoyed me cause it happened every several minutes, it was impossible to work with the computer.

             

            After browsing the net I found out a solution that worked for me, at least works without even one occurence since last night, where it happened every several minutes when it did.

            1) Open start menu with right click and select "Power Options".

            2) Click on the "Choose what the power buttons do" (on the upper left pane)

            3) Click "Change setting which are currently unavailable".

            4) Below the "Shutdown settings" uncheck "Turn on fast startup (recommended)" - on my machine this was checked by default.

            5) Save settings exit and reboot.

             

            I hope it really fixed the issue, but who knows, as it started (after several days of operation) the first time it could come back again.

            Anyway, it is definitely a HW/FW bug, probably related to the power management. I hope Intel will make all efoorts to fix this quickly, cause it looks like very epidemic issue.

              Hello cvare ,

               

              Thank you for the information you have shared with us and Zohar we appreciate you have taken the time to kindly let us know how you solved this problem on you NUC.

               

              Hopefully a solution will come up soon to correct this issue for everyone.

               

              Best wishes,

                When you were getting the WHEA error, do you remember what the error code was? I found this on an MSDN site. Hope it helps.

                  Has anyone tried booting into Windows 10 Safe Mode to see if the WHEA error still appears? It would be interesting to see if maybe a driver or a cumulative update for Windows 10 may be causing the issues. I would try it but I have never seen the WHEA error on any of the NUCs I have used.

                    Agreed, thanks Zohar!

                     

                    One more question, you said this is on 2 different systems, "the problem exists (on my machine) also with Win 8.1 Pro x64." is that a NUC as well?

                     

                    Thanks!

                      Hi MrMitch,

                      I have seen this message same days ago Re: NUC6i5SYH and WHEA about windows 10 safe mode and WHEA

                        Yes MrMitch,

                        When it was occuring it did also in SAFE MODE.

                          Yes Cvare,

                          I did that on the very same machine, I needed to know if it is a problem of Win 10 or is it a hw/machine problem.

                          It looks like what I did helped, it did not crash even a single time since.

                              I have the latest update 36
                              But still the problem , which is that the machine does not work !!
                              Is this a problem only on Windows ??
                              Or is it on all systems ?
                              I'm from Saudi Arabia Which way to return the device to the company ?
                              Thank you

                                Since this week I'm getting WHEA error in Win 10 pro. As soon as I get to win 10 home screen, the error appears and reboots the nuc, and this loop goes on forever. Sometimes it doesn't even get beyond the bios nuc posting. I updated the nuc to the latest 036 bios and problem persists. Also followed suggestion to uncheck memory setting trip optimisation.

                                My nuc6i5syh was manufactured Jan 7th 2016. Is has installed 2 x 8gb hyper x 2133mhz ram modules, a crucial 500gb SSD and a 1TB WD Red HDD.

                                  Looks like this has nothing to do with update from BIOS 33 to 36?, i am worried about updating mine. I am not getting the error, just other small issues.
