Idle: howto draw less power

[Tony Williams]

Ubuntu is the O/S and my rig pulls 100W from the wall

RAM 2x4 1333mhz = 7.6 GiB
CPU: AMD Phenom(tm) II X4 955 Processor × 4
GFX: Gallium 0.4 on AMD RS880
PRI HDD IS from HP MS 250GB but I have SDD M4 too
MOBO is: ASUS m4a785TD-evo

mobo is my sisters, cpu I was gunna give to her and use her old one being just a dual one unless I need cpu power. Has +4 HDD (more needed but SATA is ful up also its 3gb/s. Got GFX cards but see small point atm HD4470+HD5450 (or6450) passive cooled.

(ideally quietier and more passive - swapping CPU fan for bigger and need fan controller)

Any advice on when idle how to save power? closing the GUI? close VMs? Can I power off 3 cores and run one? and underclock?

The most important thing is to check Cool'n'quiet is enabled in the BIOS, followed by undervolting (and underclocking if you can spare the processing power). Make sure to check stability in the usual ways.

After that you're well into diminishing returns, but have a search around for linux power saving guides (e.g.).

I have a higher end sys which idles 200w. Any idea how low I can go with wattage on here? Maybe setting a RASP PI + HDD's insted but lpan on sat+ipcam. Might test the HP Microserverl;

Is your PSU 80 Plus?

Hi, if you leave your PC on 24/7 and don,t use it for periods of time even overnight you might considur using Advanced Power Options in your OS > Win 7 -

To access your Windows 7 power management plan, go to > Start and type > power options in the search field. Under > Control Panel pick the top result, i.e. > Power Options.

Windows 7 offers three standard power plans: Balanced, Power saver, and High performance.

Sleep Modes Explained -

In the actual Sleep mode, the computer doesn’t turn off completely and still uses a lot of energy to power the RAM. Monitor and hard disk are turned off, but as soon as you touch the mouse, the computer wakes up.

Hibernate means that the computer essentially turns off, but first the RAM is saved on the hard drive. When you reboot the computer, the RAM is loaded from the hard drive, so that you can continue where you left. This procedure can take a minute or two.

Hybrid Sleep is a mix of sleep and hibernate. The computer will go into sleep mode, but it will also save the RAM to the hard disk. If the battery runs out or power fails while during hybrid sleep, the computer will reboot as if it had been in hibernate.

Wake Timers allow the computer to be woken from sleep or hibernate, for example in response to a scheduled task (set respective trigger condition). This can be used to run backups and other remote tasks during the night.

Great answer but you missed this;

Ubuntu is the O/S and my rig pulls 100W from the wall

To run your PC at 100w per hour based on if one unit of electricity costs 14.1p?

To change watts to kilowatts divide by 1000
100/1000 = 0.1

14.1p x 0.1 = 1.41p per hour to run.

If the light bulb is on for 4 hours every evening, how much will it cost a week?

1.41 x 4 x 7=39.48 = 39p a week to the nearest penny.

How much is this a year?

39.48 x 52 = 2052.96p = £20.53 to the nearest penny.

So it costs £20.53, based on that over the year it uses very little, do you have other device's running when using the PC?

The most common one is the TV, switch then off if you want to lower your electric bill.

The only other thing you can do is power down if you leave your PC for long periods or get rid of it.
