CPU overclocking question - Captivate General

With 4.0.4 i can only overclock to 1.28GHz - why?
With 4.1 - 4.2 - 4.3 i can over clock to 1.40GHz - why?
Also, whats the best app to use for overclocking?

1. Check your voltage. Higher voltage = higher ceiling IN GENERAL (other cases apply).
2. Non. Zip. They're all the same, doesn't matter.

Mainly because of different CPU voltages set to each OC step in different kernels.
There is no best app for overclocking. Use Semaphore Manager for Semaphore kernel, Devil Kernel Manager for Devil kernel, Gear Tools for Gear kernel. Everything else does the same thing. Also, Live OC will give you better performance gain, but worse battery drain and potential stability issues. Step OC will give you higher CPU frequency, less performance gain and less battery drain. To avoid stability issues don't chase max frequencies, but better play with CPU governors and I/O schedulers and you'll see that OC is not so important.
Try Step OC 1.2GHz (safe), Lagfree CPU governor, Min 400MHz, ROW I/O scheduler, zRAM disabled - gives best performance on most ROMs.

Non Overclocked kernel

I want to make sure I'm not trippin', I've searched all thru the dev forum, and I don't see a non overclocked kernel. everyone complains about battery life but they are using a kernel that wasn't geared for battery life. oc kernels are for performance and bragging rights. we need a stock kernel with uv and ram optimization along with battery optimization mods

Why not just not overclock? Also, the kernel that comes in Inspired Ace isn't overclockable.
There are many battery saving options! If you have the Leedroid kernel, in setcpu you have the option of running your proccesor at Powersave, performance,smartass and so on...this is also in a few other kernels but I am not sure which ones at the moment.
And if you are really hyped up on saving battery, shutoff haptic feedback, turn of data when you are not using it, lower screen brightness, Use a task killer to kill stray apps(if you were playing angry birds kill it afterwards).
These are a few things you can do that will increase your battery life significantly...
With an overclock capable kernel, you can underclock. I run mine at 921 MHz and don't notice any performance hit. I've tweaked the undervolt to as low as I can get away with. I get pretty awesome battery life that way.
Before you ask, I'm using a kernel I compiled myself from HTC's latest linux source for the Inspire. It's essentially stock with only the addition of the frequency table and hooks for OC/UV.

This.
Simply underclocking will solve your problems. I prefer to run @1.4 Ghz. I have everything optimized for speed & efficiency and still don't lose in battery performance.
Running CM7 with LordMod UE 2.6 kernel and smartass CPU governor, I can set the max speed to 768mhz with very little performance hit noticed. I might just keep it that way, haven't decided yet. Scrolling is still smooth, Angry Birds is still smooth. The cool thing about running max 768mhz with the pinky undervolt script is the CPU voltage never goes above 900mv.
I'm running CM7 with nightly 91 and on my Vibrant, they made a kernel that was stock uv no oc and u could use it all day, literally....

[KERNEL AOSP] Thalamus 2.6.35.14 mod

This kernel uses AOSP camera driver so it's most likely compatible only with Redux 2.0 (tested) and Oxygen (not tested)
Before you do anything- make a backup
It's my lame attempt (I'm a modder, not a dev) to get more battery life without loosing stability of original kernel.
Kernel is based on current thalamus 2.6.35.14 sources
What is changed (mod8):
-Vdd levels sysfs interface is back, this time seems to be stable
-default voltages for CPU clocks <700 MHz are lowered a bit- keep this in mind when playing with UV
-headphone volume boosted a little- needs to be tested
-more optimized compilation- kernel should use CPU in more efficient way (and kernel is 500 bytes smaller )
-big thanks to paul8944 for testing
What is changed (mod7):
-removed sysfs Vdd levels interface- it seems that it was responsible for instability and FC's in mod6
-USB transfer speed is higher (was ~800kB/s, now ~2MB/s for write operations)
What is changed (mod6):
-added sysfs Vdd levels interface- VDD_MIN is set to 800 mV, VDD_MAX to 1300 mV, step is 25 mV (this works fine with IncrediControl)
-available governors: ondemand, powersave, conservative, performance and smartassV2
-conservative governor is tweaked a little (should be a little less conservative)
-USB transfer speed tweak- needs testing
-other fixes
What is changed (mod5)
-lowered minimum cpu clock to 128 MHz
-more clock speeds are available up to 1113 MHz
-added smartass and smartassV2 governors
-tinyRCU replaced with preemtive tinyRCU
-enabled call recording (not tested)
-many other fixes and improvements mainly form ch33kybutt's and elevendroids' sources
Note about smartass governor- after longer period of inactivity you have to press Power button for about 2 seconds to wake up the phone
Installation:
-make a nandroid backup (just in case)
-put zip on SD card and flash in recovery, I suggest also wiping dalvik-cache (just in case)
Download:
thalamus 2.6.35.14 mod8
md5: E526C99D4326F5B11D02DB60FEFA169F
Previous versions:
thalamus 2.6.35.14 mod7 (description above), md5: 7AB623BCC5E28D9BC8A012EDD9E9BBC7
Mod6 is not available due to instability
thalamus 2.6.35.14 mod5 (description above), md5: 7DC3E94E56FD00C49FEB5C713033DE33
thalamus 2.6.35.14 mod4 (128 MHz min cpu clock, default governors set, non-preemptive TinyRCU) md5: E7DD4637D8838A6E1A64E763C8A4D549
Kernel sources available on Github
I'll give it a try, seems good. I have one question and one suggestion:
the question is: what are the reasons to enable / disable the intermediate frequencies? I don't know if it can save battery, become more stable or what. But the original kernel with only 6 frequencies available works very fine for me
and the suggestion is to add the syscf interface for being able to change the voltages. It could save some battery life if our Desire stands it (mine does even at 800 mV )
i flashed mod5 over mod4, with the result of non working wifi, then switched back to mod4 -> turned wifi off (read your post in the redux2-thread, but i didn't use tb), flashed again, no wifi. now on mod4.

I was not satisfied with default cpu clock table
-128 MHz uses ~20 mA of current less than 245- it's about 10% saving for iddle not locked phone
-for me 691 MHz max clock is really enough for my needs, it was not available in stock version
-more speeds make governors able to better match cpu speed (and save some juice)
-there are some performance fans so why not enable also 1113?

Looking what caused this, I'm not sure if it's wlan driver or preemtive tinyRCU (not present in mod4)
Download temporarily removed
EDIT:
It was wlan driver.
Corrected, reuploaded package

Apologies for this noob question as im a Desire HD user and spend all my time in there. But i installed MIUI rom on my brothers Desire yesterday. Will this kernel work with MIUI, which is an AOSP rom?

I never touched MIUI kernel so I can't tell.
MIUI framework is quite heavily modified, I can't tell if drivers included in Thalamus kernel will work with it or not

Yes it work! But without camera. MIUI needs the 720p camera drivers.
Does this kernel include the conservative governor? I think you mentioned somewhere you removed it.
I find the conservative governor perfect for a screen off profile, that governor would be a reason to try it.

Yes, conservative was removed. IMO smartass replaces it's functionality but it is not as laggy when raising cpu clock.

Too bad, with screen off laggy behaviour when raising the CPU-clock is exactly what I want.
With the conservative governor reaction to the power button is instant, smartass was really irritating me when pushing the power button the days I tried it.
I used setcpu with a screen off profile with conservative and ondemand with screen on (on gingervillain) which was just perfect.
I think that the best settings for a screen off profile is to use the same governor as with screen on (it takes a few seconds to change the governor so it can be a bit laggy)
I use ondemand 245/245 with screen off and ondemand 768/245 with screen on.
And of course, if min and max are the same value, it doesn't matter what governor you are using.

I use the FTP server with screen off, a script that functions as webserver to name two examples. So I need it to be possible for the CPU to be at more than minimal speed.
Then conservative should be a good option, but still thinking that there must be no much difference if you use ondemand.
I also don't like smartass

You're probably right, but isn't tweaking for 1% battery saving part of the fun?
So which governors do you think should be in kernel? I don't want to include all available

I couldn't agree more
I think that the most used governors are conservative, ondemand, interactive and smartass (don't know about the new governos: smartass2 and others)
But for me, having ondemand it's enough

Do you want a dedicated build?
So as for now governors will be ondemand, performance, conservative, powersave (even more conservative than conservative ) and smartass- more likely v2.
I plan to release mod6 when I'll implement SVS

Trying Glados kernel, need questions answered

So I've been using Morfics Trinity kernels since I got my NS back because they are just awesome, but I once Ezekeel released a kernel I wanted to try something new, I just have a few questions, I am running Quadrant and hitting half the IO as morfics kernels, running Bionix 1.5 which has the IO patch in it so I'm wondering why it's so low.
I have it to Live OC to 110 which gives the same 220mhz bus as Morfics kernels unless I'm mistaken, why is the IO so low compared to morfics and as far as the ARM voltages and INT voltages, what do they control exactly and what is the lowest safest voltage for most NS'. I'm using NSTools for all these mods.
There is a thread on voltages in the dev section, but it will vary from device to device. The lowest safe voltage for yours may be stock, or may be much lower. You could pick one voltage at one freq and lower it by five. Run like that for a few hours. if problem free, pick the next freq and lower that by five... It'll take a while but you'll be more certain of the limits.

its not only about cpu and bus/gpu speeds, otherwise all the kernels here would be at the same performance levels. each of our wonderful developers adds their own recipe of optimizations too. plus it matters how they are compiled(toolchains), kernel versions, and more.

How to set fernel faux

Hello, I flashed ARHD 6.5.5 with faux kernel.
I want to know how to set this kernel with System Tuner or Faux Clock.
My smartphone is Sensation XE. Thanks
Actually is set:
max clock 1,512 ghz
min clock 192 mhz
governer on demand
global voltage 0mV
GPU IO Fraction 33
I don't understand your question. What do you want to set, the CPU frequency or the voltage?
Faux in its kernel thread write : "For frequency control and voltage adjustments use SystemTuner by 3C or FauxClock app by Romanbb". What it mean?What can i do with this apps?Can i get better performance setting this values?
Thanks
Hi,
With this app you can test different frequency from 1.52 to 1.8 Ghz.
You can see witch one is better for your usage and batterie life ...

It means you can overclock/underclock and undrevolt.
Overclocking can lead to better performance, unvolting may increase battery life a little.
Ok, but in your opinion which is the best combination?
What happens if i set the governer performance?i don't see any difference!

I'm still experimenting really, I leave it at 1.5GHz but I've undervolted by about 50 but haven't really noticed that much difference in battery life.
For governor I just stick to On Demand. Here's an explanation of governors: http://forum.xda-developers.com/showthread.php?t=1369817
maybe is better if i keep the stock kernel
now i reflash with stock.
IMO to have a custom kernel with default setting have no sense!

Antutu and CPU guvernors.

Wanted to show difference between different CPU governors in Trckster Mode and how they affect performance. Note that phone is only slightly overclocked so this IS NOT competition.
First image is with CPU governor ON DEMAND
http://postimg.org/image/ntw6iyts7/
Second screenshot is same overclock ONLY change is that CPU governor is changed to INTERACTIVE
http://postimg.org/image/huxvhbjhv/
As you can see difference is rather big 1100 point in Antutu just by changing governor. Phone is on stock ROM with Phantom Kernel 4.5 overclocked to 1242 MHz. .
