This should be looked into.
Overclocking (CPU and RAM)
=========================
Coreboot could be modified to support overclocking. Here is an example
patch on gerrit (not merged in main):
<https://review.coreboot.org/c/coreboot/+/42547>
Coreboot can also be used to load custom SPDs for the RAM if you want to get
into re-binning (as it's called. Thank you Riku for telling me that this is
what it's actually called). Useful if you want to quickly test.
Libreboot is starting to support machines where some users may want to start
overclocking their CPU/GPU/RAM.
As for GPU overclocking: usually there are programs you can run for this in
your operating system, but sometimes on laptops with dgpu, the VGA ROM might
limit it in some way.
This article is from someone who modified the VGA ROM on their AMD Radeon
graphics chip, in a laptop:
<https://habr.com/en/articles/232265/?_x_tr_hist=true> - it is an example of
the sort of thing lbmk could automate, when auto-downloading those VGA ROMs,
on certain machines. NOTE: Page is in Russian, use a translator.
The type of people (enthusiasts) that like Libreboot would be into this sort
of thing. It may be interesting to study, especially on haswell machines.
Haswell

interesting video on alienware laptop (haswell), and there are other examples.
those machines, whether they get ported to coreboot or not, could be used
to study what affect those options have: take dumps of hardware logs using
various utils, before and after, to study what change those settings actually
makes. this could reverse engineered to then add those options in coreboot.
haswell overclocking would be very useful to have, on libreboot machines,
because you can get some still-very-nice CPUs for these machines.
