Hi,

So to preserve my Radeon HD 3650, I have two options:

1. Re-flash the radeon BIOS with a more adequate PowerPlay table,
which would contain a much lower frequencies for the memory and GPU.
2. Wait for the proper PowerPlay support in radeonhd.

Right?

I think power management is MANDATORY for graphics chips meant to be
embedded into laptops. Any way to put the pressure on AMD/ATI to open
up the documentation for such a feature?

Regards,
Ilyes Gouta.

Hi,

Is there a way to retrieve the GPU temp? Is there any embedded sensor
that can be read out?

Nope. Maybe the Linux Catalyst drivers do this though.


You should be worried about the shorter lifetime of the card due to high
temps.

Yeah, but we're not using any 2D/3D functionality/acceleration under
Linux, so the GPU shouldn't be that hot, is it?

It is hot. GPUs don't seem to have "idle calls" like CPUs. They run hot
all the time unless you reduce the clocks (Catalyst does this). The fan
would stay silent if it wasn't hot (it's BIOS controlled).
