Does your 6820HK have cores that are 5c or higher than the others?

  1. Yes, I have a 6820HK that has 1 or more cores with a high temperature differential, greater than 5c.

    You were concerned enough to test and verify, which is good, now you know :)

    A lot of people are not very concerned now or they don't know. But later down the road, maybe they want to try overclocking for extending the life of the laptop. Then it is all too late bro:no: It's bad enough with soldered i7... But even worse when it does not function as intended.

    Hey all. i just got my 15 R3 6820/1070 Today and after a few Firestrike benchmarks i noticed That some of my core temps are 20c apart

    Core #0 91c
    Core #1 79c
    Core#2 86c
    Core#3 71c
    Package 91c

    Im kinda lost on what i should do here? I guess the only thing there is to do is contact dell and ask for a CPU replacement?.

    Cheers.

    Thats a faulty CPU. Repaste will help, but in your case its hardware.
    Send dell a screeenshot and get a replacement.

    Would you recommend getting a replacement Laptop or just making them come and replace CPU/Motherboard? and then if possible get them to use my thermal paste.

    Thanks :)

    They wont replace the CPU/motherboard for you. Even if they did why would you do that when you can get a fresh one.
    20 C differential has to be replaced.
    Repasting the new one will help.

    Ah okay thanks :) It was just because ive been waiting for 3-4 weeks for it to arrive and dont want to wait again for a replacement but if that is the only option i guess that will do.

    Even though this is a 6820HK centric thread, I can definetly say Intel's binning for mobile CPUs has been horrible at least since Haswell if not before.
    My laptop has a 4710HQ, which I recently unlocked. And here's what it shows on Heavy Loads

    While on lighter loads I get this:

    A difference like this is most definetly not good and it's clear they are still doing it with "Higher tier" mobile CPUs
