It looks like I can't push my old GTX 650 2GB beyond +50 MHz without hitting the upper core voltage limit. Afterburner allows me to reach higher speeds, but I'm limited by the maximum core voltage afterburner permits. Every time I encounter instability, lowering the core frequency helps and keeps temperatures low (around 60°C on the Heaven test). If I could raise the core voltage past +62 mV, I’m confident it would stabilize at least at +100 MHz with temperatures around 65–70°C. Also, I understand this isn’t the main issue, but my power level is disabled and shows no values.

In the Afterburner configuration, turn on "Unlock voltage control"

It's secured within the BIOS and only BIOS modification tools can handle it, but this is quite risky. VRMs remain unchanged.
