Hi guys,
i've undervolted my A6-4400M CPU and have pretty good results, but i noticed that the CPU doesn't switch to the lowest P-State (9x = 900MHz), even if it has 0% load.
It uses all of the other P-States, depending on load and windows-energy-options.
Actually, since i undervolted it, the "turbo-state" can run all the time.
Back to topic:
1.)
Do you have any explanations why it doesn't use all P-States?
Any solutions?
I could probably replace one of the P-States to form a "new" idle-P-State (20x and 17x are quite redundant imo.), but i don't know if it would use this state then..
Bonus Questions:
2.)
I searched through the entire internet, but i didn't find anything to undervolt my GPU (7520g of the APU) - MSI-Afterburner doesn't let me change anything.
Do you know any tools?
3.)
Is it worth to try undervolting the NB of my Laptop?
Are the voltages usually very sensitive or is there room for some undervolting?
(I know NB doesn't take a lot of power, but on a Laptop every Watt counts
)
Information:
Windows 7 x64
Lenovo N586, 2*4GB DDR3-Ram
A6-4400M APU (2*2,7GHz / 3,2GHz boost) + 7520g GPU
AMD Chipset
Undervolting tool: AMDMsrTweaker (command line)
I would really appreciate your help.
