Laptop crashes when OC-ing. (ACER NItro AN515-41)

D1stRU3T0R

So I have an ACER NItro AN515-41, and when i'M overclocking the GPU, no matter how much or what, it's crashing MOSTLY when it's idle, BUT never crash when in games. So if i'm playing 5 hours, nothing happen, but when i play 2 hours, go out, and let my laptop idle for 1-2 min, it's crashing. I tried overclocking with powrt limit increased, I tried whiout touching power limit increase (so at 0%) and problem still happening. Maybe a BIOS problem, someone has a fix for it, or who is developing bioses for these laptops ? I would also request some CPU overclock, i found a very bad way to undervolt, so It can throttle less but still. Also, i can see VERY bad performances in games. Like 80FPS mm with Excavator CPU ? WHat is this ?

The internet often talks of stress testing and benchmarking after and overclock but as you've discovered you can also affect the other side of the spectrum while overclocking. Coming out of sleep mode, waking from idle, or just sitting at desktop can sometimes drop power levels to their most energy efficient. IF you've applied an undervolt you may be stable at 10-100% utilization. However, the 0-9% on the low end where you idle could be unstable (ie; not enough voltage). This is often the most difficult area to pinpoint in terms of stability, and changes of -0.005v could make the difference.

This is how I ended up at -0.115v undervolt personally. Try a slightly less aggressive undervolt and see if you still experience these low power level crashes.
