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....

Benchmarking results faux & trinity kernels on CM

This post has been edited because I added Mandrobench results because it utilization of both cores. Mandrobench scores were identical for both kernels. Running Mandrobench at 1500 more than once tended to overheat my phone and cause reboots and other signs of instability.
One thing is clear, if you run either Faux or Trinity kernel you must OC at least to 1100 or you take a huge hit on performance.
I ran 4 different benchmarks on every configuration of CM 10 times with the Faux and Trinity kernels. I normalized the results so that each benchmark was evenly weighted and so the numbers are better understood they were normalized so that CM with its own kernel scores 100. All other numbers are relative to that. The 4 benchmarks were Quadrant, Smartbench 2011, Linpack, and Mandrobench. The results are a bit surprising, I am attaching the spreadsheet so that anyone can check my methodology.
CM w/CM kernel 1000 MHz score 100
CM w/Faux kernel 1000 MHz score 77
CM w/Faux kernel 1100 MHz score 104
CM w/Faux kernel 1200 MHz score 114
CM w/Faux kernel 1300 MHz score 123
CM w/Faux kernel 1500 MHz score 138
CM w/Trinity kernel 1000 MHz score 85
CM w/Trinity kernel 1100 MHz score 116
CM w/Trinity kernel 1200 MHz score 124
CM w/Trinity kernel 1400 MHz score 140
CM w/Trinity kernel 1500 MHz score 147
Test for each configuration were started following a reboot with a battery charged over 60%. They were run sequentially the same way for each configuration. Each number above was the result of the averaging a total of 30 benchmarks.
Interesting note, the first couple Quadrant scores on each run were generally lower than the rest, result of caching by the phone perhaps? On certain configurations the Smartbench results fluctuated wildly producing unexpectedly low scores. Not sure what the reason for this fluctuation but it is repeatable, at least on my phone, but only on certain configurations.
This took a long time, I am sharing it because I found the results unexpected and that they might be useful to somebody. Not everyone is dumb enough to sit and run benchmarks all day. Would be interesting to know how close the numbers are ran on another phone. I am intentionally only providing the numbers and my methodology, I will leave it to someone smarter to explain them.

Add Mandrobench to the list... only app that utilizes TWO cores for its benchmarking (free too). Then we'll talk.

I agree, Mandrobench should have been included, I didn't originally because it has disappeared from the market. I have searched my back-ups and found the apk, so I will incorporated them into the experiment later today. It is my understanding that most current apps do not take advantage of the dual core, therefore the results from benchmarks that are not optimized for dual-core have significance.

Let me start by saying thanks! This undoubtedly took a very long time and it was nice of you to share the results with everyone. Did you use only ext3 or ext4 kernels or a combination of both?

I appreciate u sharing your results. Just a quick question. was ur battery life changed a lot while u overclocked it. Also what's the difference between ext4 and 3

Both kernels were ext4, made much easier to switch back and forth by the new version of clockwork.
Both of these are file systems and ext4 is newer and theoretically faster, probably more so on a computer where there are more read/writes to disc. I don't think any of these benchmarks test for this. Someone else may correct this as I don't know a lot about phones, I am a computer guy, and an out of date one at that.

Running consecutive benchmarks can kill a battery in 2 hours.
Battery life is a subjective, I haven't thought of a way to objectively test it. I feel I get the best battery life with CM with its own kernel or Eaglesblood Froyo. Bionix appears to eat batteries.
After seeing these results, I plan to run the Trinity UV11 kernel for awhile and see to see how good the battery life is. The performance increase appears significant for only OC to 1100 and I like the idea of getting the advantages of a little OC/UV without having to run Pimp my CPU.
I have gotten a clear increase (hours more idle time) by simply turning off 4G and only toggling it on when I need it. I use Pandora a lot and it ironically runs better at 2G when I am bicycling (less drops interruptions in the streaming as I move around).

Really? I found that these 2 kernels gave me better battery life then the stock cm7 kernel. Also can you add antutu benchmark to the list?

some one should run tests again
I tested Trinity vs Faux in AnTuTu and got pretty much same results on charger,but off charger Trinity got about 50 more (6000 off charger and 6125 while charging)
I use UV kernels clocked at 1100.
Switched to Faux because Trinity has bugs like reboot hangs the phone and sometimes waking up take a while. Also boot image and animations are not that nice and boot sound with kernel doesn't even seem to be working.....
Trinity 6004-6120
Faux 5918-6124
CM Stock around 5500

Why are you getting such low scores? Not OC'd maybe? I'm using Fauxs newest kernel and my Antutu score was 7566. Average scores around 7300-7600

Faux's newest kernel is ~1.5 correct?
He's probably using the Trinity battery saving kernel clocked at 1.1 and undervolted.
I use the Trinity 1.1GHz kernel and undervolt to -200mV (for the lower ones, leave the top three at stock for stability reasons) and I score around 6100 in Antutu.

That makes sense. I just did a benchmark @1.1ghz and I got 6007. Ya the Faux kernel max is @1.5ghz. Its undervolted too, not much, just enough to get great battery life.

I said in post that I use UV kernels clocked at 1100mhz
I now use Trinity Kernel because Faux did not have 216Mhz option in SetCPU. I also UVed by -25 for now and set charging profile to 400+ Mhz to avoid SoD
I wonder whats the difference in battery life if you use 1100Mhz or 1500Mhz ?

It's a significant difference. I don't have any data to back it up. But I've accidentally left it on the max after a benchmark and it would be in a free fall. Especially when playing a 3D game like MC3

I've tried using both Kernels as well as stock. Granted they both seem to run better then stock, I'm currently on Trinity with Standard Voltage, because the Under voltage versions of both Faux and trinity seemed to freeze on reboots for whatever reason. They both appear to run about the same set at 1100 which is what I've set to.

I'd like to say thank you for performing scientific and useful benchmarks!

Whats your CPU Profiles!

So I have...
My G2x Is running at 1gz\.4 I don't find a need to OV it...
The UV is set at -50 at 1gz and at 800 it is -100 and at 500 and 400 at -200mv.
What are your sets? I would like to see other people's choices. I will report on my battery life later. I can't today since I have been going into recovery mode all morning.
Ps. As profiles go...
I have screen off set to 800/400. I don't like it lagging when i turn my screen on.
I can run stress test easily with my settings. No hiccups or anything.
EDIT:
So I was asked what kernel I'm using... I will post my ROM + KErnel! and just to let you know, my G2x has never had any problems so that may be way my G2x can get -200 on 500 and 400
And I am using faux's CM7 Kernel Version 0.2.4
Full name:
"2.6.32.41-CM7-Faux123-v0.2.4
Mod version
CyanogenMod-EagleBlood_v1.2

Im new to setcpu, good thread for me to learn a bit more from other users...

How are you not getting reboot problems with 400 at -200mv? I'm using faux's froyo kernel and when I undervolt at -100mv i get rebooting problems

I replied to your comment in my main post, since other people may be interested in that and that will cause them not to scan the pages.

Bump :\ I would like input

so how is your battery life?

Bad. Something about those settings messed it up. I much prefer just using the custom rom default kernel its much better on the battery

My chip could only use faux's OC 1.2ghz, using the kernel OC 1.5 would cause my phone to boot loop. I could go stable @ faux OC 1.2 with minimum UV, getting qudrant score of atleast 3000 - 3500. Another kernel that i tried is MOrfic's, I can go stable up to 1.4 Ghz/minimum UV- quadrant of atleast 4000-4300. I believe i have what they say as the "weak chip" though running OC @ 1.4 ghz doesn't make it look weak. Thanks to the great DevS!

[Q] HTC Sensation 4G T-Mobile US Kernel above 1.5Ghz

Has anyone used any kernels for HTC Sensation 4g (TMO US) above 1.566Ghz?
I am currently using a ROM by Mike1986 and kernel witch took my phone to 1.566Ghz and i am loving it.
However, i am a big OC freak and i would like some pointers on any tested kernels above 1.566Ghz, preferably that work well with Mike1986's ROM as i find them to be most stable our of all i have tried (i have tried 3 different types).
Any input is highly appreciated and welcome. Thanks team.

I honestly don't see the benefits except lower battery life and a warmer device, I doubt you'll notice the speed difference past like 1GHz. All of the higher freqs seem pretty much the same and aren't really worth the bother with, use a governor that accesses higher freqs quicker and you won't be needing high freqs.

What governor would you suggest??? also, i know that when using you phone and maybe even playing games i wouldn't see much of a difference between the stock 1.2 Ghz vs 1.5 or 1.9Ghz but it's all about the bragging rights, lol. I like to go to my geeky friends and slappin’ a higher clock frequency than they have on their poor devices or silly I Phones. Also I have to tell you from my tests I do see Mike1986’s latest 3.6.7/4.1.7 Rom using much less battery life than stock Rom. I have noticed about a 10% improvement, maybe even more.
Also i do see a big improvement in Benchmarks. When i was using stock 1.2Ghz setting i was benchmarking much lower than the 1,5Ghz i am at now.
Thanks again for the input.

The benefit of custom ROMS and kernels, is that they are optimized to run well. Unless the chef sucks, most big name ROMS are optimized and more efficient.

I was running 1.2ghz for a while and whenever I'm playing Snes roms it would FC. After bumping it up to 1.72ghz it never did it again. Although 1.72ghz may be overkill for what I use my phone for but everything seems to be running extremely smooth.

I use conservative(810/192), super charger v6, ultra smooth rosie on 4.1.6. I haven't used benches, but they'll be low on this ROM since I'm assuming it's based on the Sense 3.5 leak for sensation.

[Q] Sensation overheat..

My battery overheats and gets up to 56C!!
Probably because i wiped the battery stats because after i did that it always warms up so much. My battery also drains very fast (after 30 minutes of playing 40% are gone).. Is there a way to fix this problem?

What ROM, firmware, kernel? Are you overclocked?

IMO your battery usage when playing games sounds normal enough to me.
I second what the above poster has said. Are you over locked? Also, I doubt wiping battery stats would make your phone run physically warmer than usual...

Haha 1.51ghz ?? The CPU runs at 1.5ghz by default lol (if u have XE ROM) there isnt no point overclocking by 0.01 ghz
Anyway, Update your ROM ARGD is on 6.6.2 now.. that might improve things.
Also, When playing games the phone does get hot, Mine does it too its normal. Even more so if you have a case covering up the back too !
dont panic you'll be fine, and if by any chance your phone catches fire and burns you.... You can sue HTC and get the newest release for life

Lol thanks for helping.. I can't wait for my phone to catch on fire now
and for some reason my cpu is 1.2 ghz by default. I know phones usually get hot while playing games but 56C is too much isn't it?

well under hardware information it will say 1.2ghz but the actual processor is a 1.5ghz, But it has been downclocked to 1.2 by HTC so they could release the XE version as a 'better, improved version' (which is bull****, Its the same phone)
I only mentioned the fire part cause it was in the news last week lol

i ran cpu benchmark it showed 1188 mhz..
