Sorry for late reply. I switched back to XTU 6.5.2.38 (always check with "HWMonitor" that your undervolt is set when you reboot and back to windows). Throttlestop was a bit complicate. Here is my settings :



Incrising undervolt after "-0,070 V" didn't see package temperature improvement. This fix "Power Limit Throttling" too.

There are numerous tutorials online. While not specific to the G703, it still shows you where and what values you should aim for.

Just curious, what are your temps with your G703? When I had that laptop, it had one of the most robust cooling solutions in a laptop I have seen and temps were always in check. In my quest for every ounce of performance out of it, I determined that out of the box that particular laptop is pushed pretty much as quick as it can go. With the locked vbios, your only avenue to possibly squeeze out more performance is via undervolting. But even then, the gains are minimal. Unless you are seeing drastic drops in the GPU clocks under load with throttling, I doubt undervolting will gain you much.
