Hi,

so i got myself a Omen 17-an136ng with i7 8750H and GTX1070 two days ago, undervolted -125mV using Throttlestop and ran Prime95 to test stability.

After about 20-25min the Laptop shut the screen off and i had to reboot.

After reboot and voltage reset the Laptop continued to shut the screen off randomly but seemed to be still working (sound notifications still there when un/plugging USB devices).

I just could not get a videosignal, not even the HDMI port was working. After trying to resolve the issue for another hour it completely refused to start up. I returned it to the shop i bought it from and luckily got a replacement unit.

Now i'm curious about what went wrong: Was it a faulty gtx1070? If yes why does it die on Prime95?

Max CPU temperature was 79°C while stress testing (max heat test). Was the undervolting too much?

I don't want an exact answer but some opinions would be nice, especially since i'm a little bit discouraged to try and undervolt my replacement unit.

Thanks in advance for all replies.

Undervolting typically would not cause damage, just potential stability issues. Bad unit is likely the cause. TJunction for the CPU is 100C, running up to 80C is plenty safe.
