Status of linux-PHC

Post by tliketea » Wed 3. Apr 2013, 23:33

Howdy and hello everyone!

First and foremost I want to say, that I am a "longterm user" of linux-PHC and think this is a great and still very important project ...

Now, everything was good for me till a few months back, when I got a new laptop with an i3-2350M (Sandybridge). It's not so good anymore, because I think these processors are not supported by linux-PHC.

My question is: will it always be like this, i.e. because it's not technically possible to undervolt iCore CPUs anymore? If there's no technical reason, how can I support you guys to get things going again? :-)

Thanks + cheers,
T

As far as I know Intel removed the possibility to undervolt via software. (Or they hide it very well. ;-) ) If your BIOS doesn't have the option to set different voltages (e.g. offset), you have to live with it.

AFAIK, you can't do it on the processor, only if we can actually access the Voltage Regulator Module (on the motherboard) We might be able to scale down the voltages... I'm afraid it won't be possible otherwise. (Unless there is some secret, hidden Intel feature that no-one has located yet...)

The same here, I spent some time on that, but seems no way to do that, up to now.

Cheers
