Weird Problem with my Predator 15

Hi I have a weird problem with my 15" Predator (it has a i7 7700hq and a GTX1070). I undervolted my CPU by -0.100 for cooling reasons and it works great, but sometimes when the laptop goes into sleep mode somethigg weird seems to happen.

 

Oddly enough I never actually caught it happening, but it always happened after I left it in sleep mode for a bit and came back to it.

 

When I come back the screen is off, everything else is lit and the fans are working full speed (so it is extremely cool because nothing was running). When that happens I can't wake it up and have to hold down the power button to turn it off and then on again.

 

It may be the udnervolting (but it is only udnervolted a little bit), oddly nothing every happens while I work or game on the laptop. All games run stable and the temperatures are ok. If the undervolting was the problem it would show up during gaming etc right?

 

Does anyone have any idea what it could be?

 

Thanks!

    Well that sounds extremely bizarre, one thing you can do to help narrow things down is to wipe the undervolt (put it back to stock) temporarily and see if the problem persists.

    I will do that, I also updated the Bios to 1.11 (was 1.09) let's see if it helps, I hope it's not the undervolt, I like the current temperatures!

     

    Thanks for the help!

    If it's not solved by setting back the voltage to default values, it could be a driver problem as well.

     

    I would test without any usb devices attached and any other external devices. Updating all drvers could also help.

    I will try updating all the drivers, thanks! There is nothing connected (except for power) usually when it happens.

     

    Hmm speaking of, I don't think the problem has been happening without power attached but I couldn't swear to it. I'll keep an eye on it!

    maybe you'll find some hints in the windows events like a not loaded driver or so

    Any update on this? You can start working backwards from the most recent thing you have changed to help narrow it down.

    Hey, sorry I haven't had the issue again so far, but I can't say if it is fixed or if it will happen again, it didn not happen regularly but intermittently.

     

    I guess we can treat it as fixed until it happens again? The drivers were all up to date, so either it is not fixed or either updating the bios or disabling the udnervolting may have fixed it.

     

    In the Events log I have a warning about the processor being set to a limited performance state, about CldFlt not being supported and

     

    Windows error during fast startup "0xC00000D4".

     

    And about an unexpected reboot.

    How much is intermittently? Once a week?

    I have had the laptop since the 20.07.2017 and it happened maybe three or four times so far. As it only seems to happen when in sleep mode, and the laptop isn't in sleep mode regularly. I think I'll just let it stay in sleep mode for an hour on purpose and see what happens.

    I doubt that the problem comes from undervolting the CPU. If it was because of undervolting then this would happen every time when the CPU reaches max clock speed. It is most likely caused by some driver not compatible with windows 10. Update the killer network driver from killer network's website. This is the one which most likely can cause this type of errors and BSODs. Just to make sure that the culprit is not the undervolted CPU I suggest you to undervolt it with a bit less than 100mV, lets say 99mV, because 100mV(if your CPU is i7-7700hq) is the max voltage you can undervolt without having to underclock the CPU.

    Always post the following characterisitcs of the device:
    -Model number
    -Part number(not required, but helpful)
    -CPU
    -GPU
    -Operating system

    Helios 300 and Nitro 5 users DO NOT update the BIOS to version 1.22 if you don't want the keyboard's backlight to turn off after 30 seconds even when the device is plugged in.

    Alright, I'll see if I can update the killer driver. I didn't know that 100mV is the maximum you can undervolt without underclocking, can't go 99mV but will try 95 then! Thanks!

    Can you elaborate more on this? Mine is sitting at -0.120 without any underclocking.

    It depends from CPU to CPU. Every i7-7700hq can take different undervolting believe it or not. 100mV is the 'save' value, where it is certain that the system won't crash. It might be possible to undervolt it further, but there won't be any guarantee that the system won't crash.

    Oh yeah I know what you're talking about. Some of these chips can go up to -0.150!
