Linux noobe exploring the possibilities of Ubuntu.
My question is, how to undervolt my Dell E6530 with a core i7-3720QM? I'm running Ubuntu 16.04LTS (Loving it!) and read the posts on here relevant to my question. They suggest installing TLP, which I have done. Reading the TLP documents, undervolting with TLP requires installing PHC. Running through the PHC install it is apparent there is not a version suitable for the later model core i Intel CPUs as they use P-states. PHC would also not install for my Kernel version (4.4)
From PHC wiki page "Note: Current Intel core i CPUs use Intel P-states instead of acpi_cpufreq and are therefor not compatible with PHC."
So if PHC (and therefore TLP?) can't be used to undervolt, how do I do it on the more current generations of Intel CPUs? (or just my Ivy bridge gen)
To be clear I'm looking at a pure undervolt, not just changing frequencies (although the flexibility to do both is desirable).
Thanks in advance for any and all help, Nigel
