[Q] Recommended SetCPU Settings for HTC Desire

I want to over clock my HTC Desire using Set CPU
What should my max over clocking be , and what temperature should my CPU run at to be safe ?
I'm currently using the RCMixHD kernel.

Depends on your kernel.
Also, li-ion batteries are designed for use around 20c-60c, but as it goes past 40c, I think it has higher discharge rate.

Depends on your phone & kernel combo - 1113 Mhz is stable for the most of the people.
I suggest playing around with and test it - 1113+ is OK for some, but if you'll get reboots and the phone gets hot, then it is not recommended.
Also if you are OCing, you'll get more power, but worse battery life.

wont it consume more battery ??

I have Coutts 2.6.38 kernel and it allows me to underclock to 128MHz and 1190MHz overclock and I use ondemand since games don't like other governers. The underclock is bloody great to have as it consumes bugger all battery life and kind of balances out the overclock. However, as nagypapi said, you might not be able to get these speeds since your phone might get hot or reboot. I think people fail to realise that not all devices are the same and what works for one person, might not work for another.

Max. clock should depend on kernel support(if the kernel supports it, then that's your maximum clock). As for temperature, I have a profile on SetCPU which down-clocks the CPU when the temperature reading goes above 36 degree celsius. All other times it works between 806MHz-245MHz OnDemand.

Sort of goes without saying that the higher the CPU cycles the more battery juice your phone will consume and the quicker your battery will drain. I use GingerVillain which supports speeds 128Mhz - 1113mhz and using Richard Trips 2.0b OC kernel (based 2.6.37.4) seems to keep battery alive for a good 24hrs. If it's any help my SetCPU profiles are as follows :
On Charge : 128-1113 performance govenor
Sleep/Standby : 128-576 conservative
Battery < 100% : 128-998 performance
Battery < 75% : 128-883 ondemand
Battery < 30% : 128-652 ondemand
Failsafe Temp > 45.1c : 128-768 conservative
Seems to give me a good balance of speed and battery life, but would be interested to hear from anyone else that thinks my settings are wrong, always looking to improve my phone!

I would like to try this settings, but could you please also add priorities for each setting?
Also what is your main governor? (when you startup SetCPU)
Other thing i dont understand why people use such high cpu freq for battery charging (when its charging and im never using phone then, isnt it better to put some low freq. and power saving profile?)
Same about Standy/Screen off.

128 is too low, it makes my phone slow, 245 is better IMO.

set 245 for screen off only ... Its not meant to make your phone quick its meant to conserve battery lol

I know it, but weird, when I set the lowest value to 128, my phone's reaction become laggy, but 245 has no such problem. Maybe it's affected by kernel or rom.
sorry for my poor english

I know some roms/kernels have issues with dropping to 128 but my rom seems quite happy with it. I use higher CPU on charge and with battery above 75% to give me the performance when I have the most charge. When my phone boots it will adjust CPU according to battery life or charging profile. The settings seems to work fine for me although battery does drain quicker when I have it fully charged but that's my own fault for setting the performance govenor when I have high charge!

I'm using your way! thanks!

No!
Using any CPU frequency that is not default ( underclocked or overclocked ) requires testing and manipulating the various variables. The CPU needs to be in sync with the GPU and the other parameters. Needs modifications in the kernel itself. The device is not made to run at those frequencies. You will burn your device, sooner or later.

What is the best setting for SetCpu?

Guys! What is the best setting for Set Cpu? I need to conserve battery. My battery lasts about 12 hours. Im using a Reflex S 2.04 rom but i shifted to Leedroid 2.4.1. My settings are 768 On demand and 245 max 245 min on demand for powersave.
What is smart ass? How does it affect the system?

On SetCpu, I run overclocked 1200 till under 80%
Then about 80
700 at 70% battery
600 at 50%
I don't wish to run lower, as the desire gets a little wonky below 500mhz
3 profiles. I can get 3 days battery

I use no frills CPU - oc 1114, ondemand governor 245-1114.
Get about 12 he's heavy use, up to 2 days light. Today I have done 3+ hrs train journey with music, browsing and SMS, checked mail, now hanging about on this forum! 41% left.

All other governors are ****. Just use ondemand.
Im set at 128-1190 ondemand.

Why?
I use smartass @128-768 Mhz.

remember to use screen off feature (saves a lot of battery)

I've been meaning to ask for a while but what's the difference between the governors, such as ondemand smartass etc...? Thanks. Dan.

Because they don't work well. When you need CPU power they tend to lag and it takes that little extra longer which does my head in. Whether it's just me I don't know but it is so annoying. I have noticed it when playing games like RoboDefence. That's why I stick to ondemand because it actually works.

for the sleep off what is the best setting? screen off 245 max 245 min on demand? or 245 max 128min smart ass?

With smartass you do not have to set a profile for screen off. Smartass uses automatically the min cpu-frequency you set. So if you set smartass for screen off, you have two "screen off"-profiles. I think that could cause problems. You should set the screen-off-profile on [email protected] to avoid waking up problems, which can occur with this min 128 and max 245 for screen off-profile.

+1 Agree totally
Ondemand is the only governor which doesnt make my phone lag.

From SetCPU-Website:
ondemand – Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see “up threshold” in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed.
conservative – Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery.
performance – Available in most kernels. It will keep the CPU running at the “max” set value at all times. This is a bit more efficient than simply setting “max” and “min” to the same value and using ondemand because the system will not waste resources scanning for CPU load.
powersave – Available in some kernels. It will keep the CPU running at the “min” set value at all times.
userspace – A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor.

smartass governor – is based on the concept of the interactive governor.
I have always agreed that in theory the way interactive works – by taking over the idle loop – is very attractive. I have never managed to tweak it so it would behave decently in real life. Smartass is a complete rewrite of the code plus more. I think its a success. Performance is on par with the “old” minmax and I think smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies.
Smartass will also cap the max frequency when sleeping to 352Mhz (or if your min frequency is higher than 352 – why?! – it will cap it to your min frequency). Lets take for example the 528/176 kernel, it will sleep at 352/176. No need for sleep profiles any more!

[Q] CPU Profiles - using Smartass v2

Seen a lot of conflicting comments stating using smartass governor means there is no need for profiles to be setup and can actually be detriment to the battery life and speed of phone.
Is this true or could I benefit from setting up profiles to get my usage optimised.

Below is a quote which will explain you everything about smartass governor
From it's developer:
"smartass governor - is based on the concept of the interactive governor. I have always agreed that in theory the way interactive works - by taking over the idle loop - is very attractive.

Governors - I/O - Freq questions - combos

So I have started playing around with those. I searched over google for some awsners but since my brain started bleeding i tought i'd create thread. ( hey I work overnight, I should be sleeping).
So far it looks like this (On CM9 stable with Darkside 6.1)
Prio 100
Screen off 540-192 ON DEMAND
Prio 90
BAT > 122F 756-384 ON DEMAND
Prio 85
Charging ANY 1728 - 1026 BADASS
Prio 82
IN CALL 1080 - 384 ON DEMAND
I/O NOOP
Prio 80
APP CHROME 1512 - 1026 ON DEMAND
I/O NOOP
Battery > 10% 1782 - 1092 BADASS
I/O NOOP
So not sue if the combo of screen on screen off is ok...Also Should i ALWAYS set a I/O Scheduler ??
Thank you for your time

Batt > 10% 1728-192 BADASS I/O NOOP
Not sure on when or how to use NOOP. Also, not sure about my screen off/ on combo
Should noop be always ON ? Looking for Good battery life since mostly texting and fooling around the phone. Games at times.

Your setup looks good. Not sure about you Chrome profile, why have the min so high? I like having my screen off at that exact range, exept on conservative As for the i/o scheduler, it depends on the kernel. Im using TDJ;s also, and he recommended noop on his, so thats what I use
Setcpu
100
Screen off 540-192 conservative
99
In Call 1188-192 badass
98
Battery <=15% 1026-192 badass
97
Screen on 1512-192 badass
Battery lasts all day, no juicedefender, on AOKP, lets me switch to 2G on screen off.
I play games and xda app, get an easy 4 hours screen time

Will try it with conservative on Screen Off...Tought i read somewere it's better to keep it on Demand so you dont have bugs when going on ?

On AOKP ICS, havent noticed any bugs due or SOD (Sleep of Death) I get an easy 20hrs batt life with moderate use

So far 1:30 screen up time, played games and such. Still at 60% Bat. Prety damn good and i use a screen lock pattern wich must drain a bit more.

[q]setting cpu frequency

In rom control > cpu frequency?
What value have i set on min and max?
What type i have to set on governor?
What type i have to set on IO scheduler?
All setting cpu freq depend on what?
[ROM][AOKP][JB][RC]ARC S[Build 5]
[KERNEL][FUSION v3.7]

Have min and max set as the highest or 1.4 . set governor as performance, and have 'noop' as IO. Of course, the frequency entirely depends on what you want from your phone - best performance with high battery drain, laggy as hell performance with best battery life, or somwhere in the middle

[ROM][AOKP][JB][RC]ARC S[Build 5]
[KERNEL][FUSION v3.7]

the higher the frequency/value, the faster and better performance your phone will have. So depending on how slow/fast you want your phone, set the frequency/value to the appropriate/corresponding level of performance

Basicly you have to experiment with the cpu freq in order to determine the best freq for your desire (gaming,smoothines,battery drain)
As for guvernors - Performance will always keep it at max freq so it drains ur batttery like hell
- Smartass will use lower freq and less the max freq so its the best for battery life and smoothines in my experience.
If you used search you would have found -> gouvernors info
Gouvernor Infos
AS for I/o sched -Noop has the best ratio for perfo/batt life.
Performance sheeet comparison of sched and guvernors

Better set Interactive because performence eats battery

cpu
what the best cpu ferequency for arc s?
for bettey battery life?
what is governor?
what is i/o schedual?
ihave a problen in set cpu
i set the cpu for an app , and when i go to app and after close the app , don't back ferequency to values that i set in the main screen
and the ferequency set to maximum
