Undervolting 960m?

I was wondering if anyone on here has been able to undervolt a 960m dGPU? I'm currently using a Dell XPS 15 9550, and I was able to undervolt both the CPU and the iGPU but I'm not able to undervolt the dGPU (960m). I downloaded MSI afterburner and I unlocked the voltage on there, but I can't open the voltage settings. Does anybody know why? I would love to get better temps on my dGPU because in some games I thermal throttle and it's a pain.

Have you replaced the thermal compound and blown all the dust out?

GPUs with the M at the back are all hardware locked on their voltage. Besides you need to flash the BIOS to undervolt the 9 series cards even if they are the desktop ones.

Really? That sucks... How would I go about flashing the bios? Or would that be too difficult and repasting the CPU and dGPU be my best option?

Not gonna change anything. You cant bypass hardware locks with software.

So I thought I'd update this thread. Earlier today I was able to successfully replace the thermal paste on both my CPU and GPU, the thermal paste job Dell did was horrible. After redoing the thermal paste and cleaning my PC out, and undervolting both the CPU and the iGPU, my temps a rock solid! After undervolting the CPU to -173.8mv and the iGPU to -176.8mv (I don't know how I got it to go this low honestly) the temps went down to 58c at idle. After redoing the thermal paste the idle temps went down to 38c! Then in Overwatch, my temps went from the high 70s to the low 60s!
