Root Set CPU for root users

[DesirableHTC]

I'm thinking of installing this app, as the rom that I'm using allows to be over clocked and under clocked, i believe. What i want to know is, what is it all about? i have seen the terms mentioned and all that, but I'm not entirely sure what its all to do with, what will the advantages be? and what is the best way to use it?

Thanks

If you under clock the cpu things will run a bit slower, but you will have a little longer battery life & in theory the cpu will last longer.
If you overclock the cpu then everything is the opposte to what i have just stated.

Cheers mate, doesn't sound like there is much point to it then..... I would have thought it would be best to leave the cpu to do its thing?

Always best m8 unless you are into overclocking, tried it on the pc a couple of times but you tend to get system instabilities.
Under clocking can be advantageous if your battery life is crap though

The best 2 uses of it are:

- ondemand cpu scaling.
This is automatic. Basically it will underclock when the phone needs less power. Saving you battery, but performing just as fast.

- Mega underclock when screen off.
Things can go as slow as they want when your screen is off, so no need for all that power!


You can't overclock unless you have flashed an overclocked kernel. If you haven't, then set cpu is simply a tool to save you battery, yet keeping the same level of performance, as such i highly recommend using it. There is simply no good reason not to use it.

battery life is quite good actually..... in fact, i have had this same rom on for 2 whole days now!! NeYoPhyTe 1.7.1 I just love it, smooth, fast (1500+ Quadrant) bug free battery life is cushty. I have a rom that is waiting in the wings, but personally, i don't think it has a chance at the moment!! lol BTW, its the "get frost" ROM. I have been looking for a good non-sense rom and that one looks nice.....

Thanks Lekky, i might give it another try. I had it installed earlier, but cos i didnt know what to do with it i just uninstalled it.

I am using the same rom as you got to admit it is fast.

literally open it, select ondemand from the scaling dropdown, tick set on boot, and thats it.

If you want the screen off underclocking then go to the profiles tab, add profile:

condition: screen off
max: set to minimum allowed
min: set to min allowed
govenor: ondemand
priority: whatever (this is used to give a priority when using more than 1 profile at the same time)

voila, untick notifications in the profiles section to remove the notification icon btw

I tried this, with pretty much the exact settings given above, and it lagged everything up for a few seconds after unlocking. Couldn't stand it. In the end I decided my battery life was fine anyway (six hours on aeroplane mode uses 1%) and just gave up on it.

I love this app. Set my clock speed stupidly low for when the screen is off.

One issue I find though, when I reboot, I have to disable perflock, then disable and enable profiles (the general profiles not individual ones) before it will underclock as per my set conditions.

Its an annoyance but no big deal.

Using it in a widget locker / launcherpro environment with battery conditions set incrementally for almost every 10% of battery (down to 50%), I don't find it detrimental to performance during standard home screen navigation or application launches.

turn up the maximum value for the screen off profile. find the lowest max that will give you no lag and use that. Its like 1 minutes work and it will save you battery

Seriously!! ... how have you managed this?
Best I can get is 5% to 7% on aeroplane mode for 8hour period.

I have tried this mate, but i cant add a profile.... how do i add a profile mate?

Cheers

Yeah i know mate, but i cant find an option to make a new profile....? when i click on profiles there is just a list Charging / sleep/stand by / battery profiles / power / power / fail-safe profile. But i cant see anywhere to create a new profile...?

depends whether you know how to overclock properly or not though..

personally, i haven't got the faintest clue how to overclock whilst keeping stability, but the company that made my pc have overclocked the cpu from 2.9 to 4.2 GHz

I bumped my pc up from 2.4 to 2.8 GHz was ok till i ran a game then crashed,
still a lot depends on what settings you can access etc.
Holds up pretty well on smartphones too, i would be interested to see how high the snapdragon cpu could be clocked while remaining stable though.

the whole handset is running pretty hot anyway, so I wouldn't want to go too high

Got to admit the specs on the handset made my first 3 pc's specs look sick.
still its always nice to know what a cpu is capable of to know how hard it is being worked as standard.

you're probably using an old version, on mine there is an add profile button, maybe try pressing menu on yours or something

I did indeed have an old version of SetCPU lekky. I have now got the latest version and set the profile as you stated, Thanks.

 

[lekky]

no probs

Seems to be my current ROM, my battery pretty much doubled after installing it. This is Psychosis 2.1. Usually my battery drops 1-2% over night on Aeroplane. It's a pretty clean install too, I don't fill my phone with apps. The only notable service I have running is Tasker (which is doing nothing except disabling Aeroplane and Silent at 07:00).

I will try SetCPU again some time, with an increased screen off maximum set. But honestly I doubt it will make much difference to my current setup.

 

[Kev23]

Thanks Tunga, think i'll give that ROM an install and see what happens.

 

[Tunga]

Note that after 3.0 he changed the base ROM from NextSense to LeeDroid. I wouldn't have thought that will matter but it's possible. I haven't tried 3.0+ so not certain.
