Undervolting core i7 on Z11?

Heya,

First things first: The new Z is the best laptop I've owned so far. End of story. Had MBP, MBA, AW m15x and several Dells, but nothing like this.

Second:
Im not a big fan of hardware overclocking/undervolting (anymore). (Referring to the " Insyde hacking" thread.)

Ok, with that in mind; how do I software undervolt the mobile core i7 processor?

Tried good old RMClock, which doesn't work. (It hasn't been updated for years, so I didn't expect it to).

CPUgenie... didn't work.

Crystal CPUID.. didn't work.

Now I'm out of own ideas, started searching. The only thing related to my "problem" (which actually isn't a problem, I'm just a big fan of undervolting and want it that way), is this thread:

ThrottleStop thread here on NBR.
Downloaded it, tried it... doesn't work. I don't get access to the voltages.

So.... basicly I'm out of suggestions.

Go!

Edit: CPU-Z screenshot gives same low amount of information as most other programs. They don't read all the information correcly, it seems? Big "Hmmmm?".

 

Unfortunately, it is impossible to undervolt Nehalem/Westmere generation CPUs by software means.

Intel has completely removed VID control from the MSR registers, so it is impossible to change it. It is even impossible to read the current voltages actually because Intel completely changed the meaning of the MSR control register and removed the VID/FID information alltogether.

Nehalem/Westmere CPUs have advanced dynamic overclocking abilities, which also require full voltage control by the CPU. Unfortunate consequence is that we are not able to control the voltage of the CPU with software / drivers.

Also, this hides the differences between LV/ULV/SV versions of the CPU - while in Core 2 it was possible to get the standard voltage CPU to the TDP envelope of "Low Voltage" CPU this is now impossible.

The only way to undervolt Nehalem/Westmere CPUs now is by manual VRM override if the motherboard and BIOS/EFI support it. This is clearly a suboptimal solution and it is not possible in majority of notebook boards - this feature is usually present only on enthusiast-class desktop motherboards like models from ASUS, Gigabyte, DFI, etc...

 

Good, clear answer. Thanks!
