Undervolting on laptops.

Honestly, I think this should be more of a thing. On both CPU and GPU. I know MSI afterburner can offer this, but there's no news on if that will continue to be developed since MSI and the Russian programmer were having issues with payment. Aside MSI's top tier laptops, very few OEM actually offer undervolting in the BIOS of tuning softwares. A lot comes down to silicon lottery but still, if you could shave 30mv off your cpu and drop 5c for no loss of performance? Who wouldn't? It would save battery too when not plugged in. Same goes for GPUs, saving mvs and optimising the curves could free up a bit of extra power for the VRAM, squeezing more mhz from that and keeping the GPU cooler...

I know most of the utilities would go over most peoples head, but for those who could or would use it, kinda sucks not having that option. Thoughts?

  • I think most higher-end gaming laptop companies already do some form of undervolting at the factory production line, AFAIK they apply a reasonable safe voltage that will work on all laptops and generate less heat,  then test them to make sure. Although it is a good idea on a personal level, most people aren't that confident in such things and so there isn't much market for it. Also I get a lot of weirdness with undervolting things so I just tend to stay away from it for good measure.

    Thats the thing with undervolting, its luck of the draw. If you get a HX or HS chip from AMD it normally runs similar voltages. I was chatting to a guy on reddit who undervolted his Strix AE about 30mv with UAFB and managed to use PBO/XFR to get higher peaks too. All stable. Yet my 6800H didn't like a 10mv reduction.

    It's kinda like overclocking, you have to do it bit by bit and stress test it. If you get lucky, you can get some gains. If not then you're stuck at stock.

    Some OEMs do, Lenovo had the hidden advanced BIOS and MSI do a full proper BIOS. I get it on budget laptops there's not much point as they're likely bottom bins, but the high end of mid tier and high tier laptops should offer more IMO.
