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?

    Well, people who don't have the knowledge about clocking or those that fear they might damage their laptops. To some, that's advanced knowledge.

    Some people just don't care enough to bother with it.

    Some would even prefer overclocking - I mean, who would underclock their gear? That's for plebs. Laughing

    I agree there are benefits to it and I would definitely reach out for that if I were saving my battery or doing low-intensity work. Gaming? I'd prefer my laptop to run the games the best it can.

    Undervolting and undercloxking are very different things though. Underclocking lowers your clocks and will keep the factory voltage curve. Undervolting aims to keep your clocks the same while using less voltage to do so.

    It's very much a luck of the draw thing, if you get a top tier piece of silicon in terms of lottery, you could say drop 20/30mv reduce your temps and keep your frequency the same.

    With Ryzen chips, if you're lucky you can use that as a core offset then PBO will see if it can squeeze a higher frequency at the same maximum voltage. So normal frequencies use less voltage and save power, but then if you're using everything it has the the ceiling it will take those 20/30mv and raise the frequency ceiling.

    I get its not for novices, but if you want to optimise your gear then its an awesome option to have.
