It is now about two years ago that I have developed a patch to set
the TMDS frequency for Radeon cards. A similar patch for Nouveau and for
the Windows ATI driver does already exist. The patch has been proven to
work well in the long term at least with the Radeon R5 230 and the
Radeon HD 6570. Other people have given positive reports as well (Radeon
HD 6970, Radeon HD 6770, see:
https://bugs.freedesktop.org/show_bug.cgi?id=93885#c24) though not as
extensively as John Reinhard with the HD 6570.
Many cards do not show heat issues at all when overclocking the TMDS.
- and even if a card did Nouveau developers have told me that it would
hardly be possible to damage a card with this. The reason why Radeon
developers did not want to assimilate it seems to be business interest
as they have told me frankly. The patch is safe and has been proven
useful (since then many people with positive experience have linked to
my site) - so why do we not include it for Debian?
