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.
