What is best practice for overclocking / undervolting a 50xx in Linux?

[arisu]

Just for input - Myself and a couple others have found that lowering the memory clocks is actually more efficient. I haven't seen any testing on newere hardware, but the idea is that anything since Turing has more than enough memory bandwidth and there is little if anything to be gained. BUT driving the memory clocks up uses more power, and that power (if running power limited) could be used to increase clocks more, or simply just not use the power for something already fast enough. It might be worth some testing when using locked clocks.

As for the undervolting, it seems to be covered. But for the ultimate in how to get hard data to make your decisions, the thread below has some great ideas.

Lowering memory clocks is only helpful for certain WUs. The ones that require a lot of VRAM and show sustained >20% memory usage will probably benefit from an increased memory clock. But it really depends.
