Re: [tlug] silicon cash eater

It is interesting that my first response to computer issues is usually:


when the solution can often be found in software settings…. that maxcpus=x line of 9 characters possibly saved me a few ¥10,000 bills…
My wallet thanks this list… ;)

Wonder if under clocking it would reduce the power consumption? Then I wouldn’t  need to do much at all. I suppose before any change it would be good to source a power meter and see if this machine is really the culprit for excess power consumption. Maybe its the i7 running 24/7 at full load right next to it…. ;)

Not as much as chopping off some cores, that's the reason the U or T
series from Intel always have high freq + SMT and less cores.
(Or you can see them shipping inefficient desktop cpus)



Interesting idea. How does one go about chopping off cores? In BIOS, or through Linux?

BIOS answer: 

Linux Answer:
by editing during boot up the grub kernel with maxcpus=   e.g.
kernel  /boot/vmlinuz-2.6.22-14-generic root=UUID=a8a39729-9d2a-425b-b84b-ecc5c7dad104 ro quiet maxcpus=1
In Windows:
setting a max process speed = 50% in power settings in windows

Nice idea, I will give that some thought.
