* Well, not so fast. The Plundervolt attack made Intel recommend vendors to enable the "Overclocking Lock" flag in the bios (which despite the name, at least on normal locked cpus it just allowed voltage control). It [https://old.reddit.com/r/XMG_gg/comments/h0wuoh/cpu_undervolting_in_bios_setup_for_xmg_and/ wasn't] a ''hard'' requirement.. but this was just the path of least resistance for most. It's not really difficult to unlock with the usual [[Glossary talk:BIOS|bios tools]], but still.

* If for some reason you need to maximize memory frequency/bandwidth (whatever the crazy benchmark or the IGP troubles above), but memory multipliers aren't granular enough, one crafty expedient is to play with the BCLK

* Put aside the no-brainer improvements that always come with undervolting, in ''thermally cramped'' systems (especially low end laptops that may have a single heat pipe and fan for all components) additionally '''''underclocking''''' the CPU to afford more overclock headroom for GPU, or viceversa, can be a winning strategy depending on the application/game.

* Undervolting is probably the most no-brainer free-lunch improvement of them all, at least in ''thermally cramped'' systems (i.e. about every one that isn't a desktop with a <100W cpu)

* Wherever exhaust heat of CPU and GPU is shared on a single heatsink (e.g. most laptops with a common heat pipe and fan) '''''slowing down''''' the CPU to afford more thermal boost headroom for the GPU <s>or viceversa,</s> can be a winning strategy depending on the application/game/environment. When graphics is integrated on the same chip, I'm afraid [https://old.reddit.com/r/lowendgaming/comments/ebjval/improving_gpu_performance_on_the_celeron_n4100/ only] cpu underclocking is gonna be feasible.. Otherwise with a dedicated gpu there should be plenty of utilities to lower the TDP itself directly.
