Hello everyone, some time by now I flashed a custom Vbios (thank you Klem) on an Acer Predator 15 G9-591 and I started doing some tests about how far I could go overclocking the gtx 970m without running too hot. With the voltage up to 1150mV and something like 300 additional MHz for the core clock, in the strongest stress condition for both Gpu and Cpu ( i7-6700hq undervolted), the Gpu reaches a max temp of 85C (with some 86 spikes but never more than that). Considering that soon I'm going to relid both Cpu and Gpu and clean everything in the internals (laptop is 4 years old) I think I'm going to have some additional heatroom. I've already tested some further overclocking and I noticed that even if the temperatures remains under 93C (which is just for testing purposes, but after relidding temps could be nicer) graphical glitches occur and after some time most games crash. But my question is, could it be because of lack of power supply? The laptop charger provides 180W Could there be an increase in overclock margins with a 230W psu or something like that? (Obviously with the same 19.5V output) If anybody tried something like that on any laptop model, or knows the matter, I'd like to know
