    New Skylake build problems

    Hello users of Hexus,

    Since I put together my Skylake build I've been having persistent problems with my computer crashing. Most guides I have checked about overclocking Skylake say the baseline overclock anyone should be able to get is 4.5GHz. Well this didn't work for me so I have gone all the way down to 4.2GHz but there is still freezes, only when I'm playing games. I have ran RealBench and the AIDA64 CPU stability test everytime I run realbench and come back my computer is just frozen, the monitor is still on but I can interact at all even when pressing CTRL + ALT + DEL. I've asked around and no one seems to be able to help me, so here is some useful information about what I have and what I have done.

    Motherboard: MSI z170A Krait Gaming board
    CPU: Intel i5 - 6600k 3.5GHz (overclocked at the minute to 4.2GHz)
    OS: Windows 10 Fresh install
    GPU: Nvidia GeForce GTX 680 2Gb
    SSD: Samsung 850 Pro 256Gb
    Heatsink: Dark Rock Pro 3

    Firstly I Overclocked to 4.5GHz at 1.325v, this obviously became unstable when I ran stability tests so I flashed the Bios and updated it just incase, still unstable and freezing. Just so you know, no CPU temp went over 60 degrees at all on any tests so I'm sure heat is not the problem.

    I then went back in and tried 4.3GHz, lowered the voltage a little still crashed so I went back to 4.2GHz voltage is at 1.3v but when I was playing CS:GO earlier it froze again, I checked temps and nothing seemed to be high. General browsing no issues no extreme heat or glitches but there is one thing that is confusing me a little. AIDA64 is not showing the right voltage, no matter what I change it too in the BIOS it stays at 1.170v - 1.185v it won't change... CPUZ shows 1.285v but not the set 1.30v so I don't know if the CPU is getting enough power or not, I don't want to mess much with the voltage as I'm afraid to damage the CPU.

    I haven't touched the base clock or anything like that just the multiplier at 42 and the voltage. If you need any information off of me please just ask, I really need to get to the bottom of this so I can see whether it's due to faulty hardware, thanks.

    Here is the event viewer log also http://imgur.com/fJ0eqd7 the critical is me pressing the power button to restart.

    Thanks guys.

    The first thing to check is whether it's stable at stock speeds. If it's not then it's likely faulty hardware of some sort.

    Re: New Skylake build problems

    Agree with the previous post. Test if you are stable at stock. Then go from there by eliminating individual elements.

    Cooling is fine you said so, that can be taken off from your list.
    CPU, RAM, SSD/HDD, drivers, PSU, GPU or the combination of any of them.

    Let us know what do you find

    Re: New Skylake build problems

    You're going about overclocking the wrong way around really - you should ideally go up bit by bit and test at each stage, then increase voltage carefully when necessary. Just because one CPU with the same model number reaches a certain clock speed does not mean yours will do the same.

    Also, you don't have to have a thermal issue to hit an overclocking wall, there are other factors which come into play and again, it will differ from CPU to CPU.

    But yeah, to check for faults you want to be at stock settings. A CPU not hitting a desired overclock isn't considered a fault.

    I have to agree, go back to stock levels and go up in little increments. Test each overclock until you find a stable one. If you still a overclocker beginner there are plenty of tutorials on youtube.

    Re: New Skylake build problems

    It's only come up once before, so, what's your PSU? It comes across as a power stability problem.

    If you have 100% stability without overclocking anything, for like 8-12 hours, probably encoding video, then you've got the golden key to try an overclock. Without knowing if the system is stable at stock (and if not it could be a lot of things, almost any single part) speeds it's harder to help you.

    Make sure you have the latest bios and it's at defaults for your first test (bar XMP, boot related options, etc).
