Hi everybody, this is my first post... ;)

I'm an Ubuntu user and I'm going to try to undervolt a Clarksfield i7 (720QM), should I expect problems patching the latest kernels?

Thanks in advance

Danilo

Hi everybody, anybody got this?

Code: Select all

cat /sys/devices/system/cpu/cpu0/cpufreq/phc_fids 
0 0 0 0 0 0 0
phc_vids is ok and I can eventually change it, but I suppose that no frequency id means that I can't really apply a voltage to a certain multiplier, and some tests I did seem to confirm that.

I even searched on google, but nobody seems to have this issue...

Any idea?

Thanks in advance.

In another thread you said you own a Core i, however anything more recent than Core2 is not supported.

phc-intel-pack-rev25 is out with refreshed kernel files. You might want to read the warning attached to it.
