Interested in overclocking my cpu. I have heard of people doing this at 1.2 GHz and still maintain stability and good battery life. Currently installed is Kernel version 2.6.32.9 after granting SetCPU su permission (and checking always allow) I find that the max overclock is at 1 GHz. Obvioulsy this is not a Kernel that can be overclocked. I tried installing some random Kernel I found online using Odin. This however failed during install and "bricked" my phone. I was able to Odin back to stock, re-root, and re-flash this ROM. Does anyone know of a Kernel that will work with this ROM and allow me to overclock? I really like this ROM so far and I want to keep it!
Thanks in advance,
Your best bet may be searching the Epic's wiki page for kernals. The sticky link is located in each of the Epic's forums.

there aren't any kernels right now for froyo because of no source from samsung/sprint
we have to wait till official 2.2 drops
Thanks I appreciate it iSaint! Is it worth flashing a 2.1 ROM and Kernel so that I can overclock or do you think that overclocking is overated and that this midNIGHT 3.1 (which is blazing fast compared to stock) is fast enough!...... I guess will I notice a huge difference after overclocking to 1.2 GHz?

no problem...if you want stability and speed then you cant argue with ACS syndicate 2.1 but i use MidNight which IMO is very fast and i've had zero problems with it so far there isn't really that much of a difference to me on 1.2-1 GHz but test them out and decide what you like 8)
Looks like I'll just stick with midNIGHT 3.1 for awhile. Any tweeks you know of that will improve speed and performance?

the no journaling mod but i think that flashes with the rom(not sure)
and i delete anything i dont use before i flash the zip
open it up system/app just dont delete anything important or necessary things i delete are (swype,browser i replace with dolphin,launcher2,live wallpapers) thats all i do bro
Thanks a lot, I've allready flashed the no journalling mod. But thanks anyway. All in all midNight is blazing fast and I'm very happy with that ROM. Have a good day!

2 cents here.
Personally 2.1 oc'd to 1.3 ghz on acs gave me more speed than midnight 3.1. Rummaging through the phone the advantages of rfs over ext4 are evident. But Playing games and multitasking goes to 2.1 acs @1.3 ghz for me. The phone flies at 1.3. Just try it. you have nothing to lose and you can easily flash back.
Ill definately give that a try. Is that 2.1 include the gps fix?

Hi all,
My Galaxy S i9000 will arrive tomorrow and I'd like to be prepared how to and which kernel to flash.
I'll probably just flash JVQ, the latest official Gingerbread 2.3.4 ROM. But I can't decide which kernel to use. My main priority is the performance and safety (by this I mean recovery options).
I have found two kernels which might fit my needs.
First of all SpeedMod Gingerbread. It has EXT4 lagfix and sound improvements etc. It seems good to me.
There are no instructions for this one, but my guess is to just flash the .tar with ODIN as PDA?
Second I have found CF-Root. There are clear instructions so I don't need help how to, but is this a good option as a kernel?
What kernel do you think is the best for the Gingerbread ROM JVQ?
Also, what about CWM? How do I boot into this recovery? Does it replace the default recovery?
Sorry for the noob questions, but as you see I'm quiet uncertain about these things, though I've read alot.
Thanks
Stock JVQ ?
Why won't you flash a custom ROM ? For example you could install Insanity's, Darky's, etc... which are sort of "packages" containing everything you are looking for.
Each one of them have a specific forum in Dev, with flashing explanations.
As for kernels, if I ever needed to change, I'd go for Glitch.
I would wait and use cf root when its released and if your not happy with the speed then use an oc kernal.there are many packages that will be available for all the mods you want in the themes section.this way you will be as close to stock as possible avoiding any unwanted issues
Sent from my GT-I9000 using XDA App
I've considered Darky's 10.1, but I dunno, I don't like the green colors and everything.
Insanity and glitch look cool. I must have overlooked this ROM, I might consider it. Thanks for the tip
Stock with CF-Root seems to be the fastest in Quadrant. I'm in doubt.
bro i think u have to keep Cf-root i install jvq and put Speedmod in it but u cant image it doesnot contain Superuser and cmw after that i install Cf-root it really better then speedmod this time not always.........i hope u can go with cf root
Have you considered other kernels like Semaphore, Galaxian or Talon?
All of these have OC/UV capabilities, EXT 4 and more performance tweaks than CF-Root itself.
Speedmod is currently undergoing major developments (less stable versions being tested). You can wait until it has a stable version before flashing.
And you can buy Voodoo control plus if you want great sound.
I know Talon has Voodoo sound v9 built in. So, take your pick
For stock JVQ I recommend to use stock kernel until the custom kernels have updated JVQ initframs.
Sent from my GT-I9000 using XDA App
I'll look intro Talon. I won't overclock my device as I want it too last as long as possible The Voodoo stuff seems interesting. Would it work if I just flashed it over CF-Root? Guess not. I would have to flash the stock kernel and then Talon again?
With the latest stock JVQ I'm getting 1400 score in Quadrant, kinda low. I'm now attempting to convert to ext4, but the system folder has too less space, trying to move some apps.
Edit:
With everything converted to ext4 I now have 2300, that's better I'll leave it like this I think. I'm fine. Thanks for the tips
In that case i would recommend to use Talon 0.3.1 without OC.

Semaphore and Talon - my favourites!
Just rooted. Im new to the droid world, so im curious, can i get a low voltage kernel? A friend has Savage Zen and brags about battery life, but would it be compatible with my default-rooted rom? Also can i backup the kernel? Thanks.
Btw i tried googling but every time i got a good lead the links were dead

If you are referring to a rooted, stock HTC Sense ROM, no, do not use SavagedZen. It is only for AOSP ROMs.
AOSP - Android Open Source Project (vanilla, like on the Nexus)
Sense - HTC's UI
You cannot use a Sense kernel on an AOSP ROM, or an AOSP kernel on a Sense ROM.
(All Gingerbread)
AOSP Kernels:
Tiamat
SavagedZen
Cyanogenmod (kernel)
Godmode
PoonKang
I know that Tiamat and SavagedZen have HAVS and can be undervolted using Vipermod. Cyanogenmod, Godmode and Poonkang may come undervolted, but they do not have HAVS so you cannot adjust it.
Sense Kernels:
Freedom by Lithid
Golden Monkey by Netarchy
ChopSuey by barnacles10
Stock HTC
None of these kernels have HAVS (Freedom used to, but it was causing issues so he took it out). Golden Monkey, ChopSuey, and Freedom can come undervolted by certain degrees, it depends on which version of the kernel you download.
I can't think of any way to back up a kernel except for nandroiding system, but I am probably wrong. Just go into recovery, wipe cache and dalvik and flash a new kernel if you have any issues.
There is a good study guide in I think Q&A stickied, telling all that you need to know about kernels. I advise you to read it. Link: http://forum.xda-developers.com/showthread.php?t=894880

You can usually recover a bad kernel by flashing to back to the stock kernel and wiping cache and dalvik. Its usually worked for me, but depends on how much the custom kernel changed things.
To OP, go check out Kernel Manager in the market. It takes a good amount of the guesswork out of kernel flashing.
I say go with chopsuey 9.1 ill say its really good left my phone off charger for 8 hours while i slept was at 41% before and when i woke up it was still at 41% i mean does it get anybetter than that
Thanks for the help. Really in depth and helpful advice . Using freedom aggressive kernel now. Still testing to see if it helped. Great forums.

What radio you using or are you not having the LTE drop out?
Benzo rom + Vindicator kernel make my N6 the device it was meant to be. Hydra kernel is not bad either.
If you've taken the steps needed to flash a custom kernel, why not just nandroid your stock build and try some rom's? I'm assuming you have a custom recovery in place if you'r playing with kernels. You don't like it, restore back to stock in less then 5 minutes. I personally have not had any issues of note on the kernels and rom I mentioned. I did have issues on other combinations, but no harm done.
The functionality additions are light years ahead of what stock offers; custom drop down tiles, privacy settings, customizations, themes, etc.

Pretty much any kernel is going to give better battery life just out of the box before any tweaking. UV by -25 and u already are saving battery. Most kernels fix memory leaks and such too. Then there's the added benefit of extra optional features like OC/UC and wake gestures.
We have another post for ROM. Why do we not have another post for Kernel ?
As we can see, we have more than 5 kernels that are from XDA developer or someone else. But which one is really good for your ROM and which one still keep updating ?
I have been using OP5T for 2 months. Have used so many kernels but i still got stuck in those and do not know which is more stable. I am planning to use the kernel from Blu_Spark. Is that good ?
Post your favourite kernel and tell everybody why you use that. It will help newbie to pick what they want.
I am using Flash kernel at the moment but I have already tried Blu, franko, arter, ElementalX etc, but honestly for me it's difficult to see any difference since this phone have already a great battery life and great speed. On my previous phone (S8) the custom kernel gives a big advantage since the phone have tons of bloat and and isn't running stock like Android.

I have tried Blu and Franco for now and both have been very good. I really think kernel performance depends on the combo with the ROM as well as your device. I'm on Liquid Remix with Franco currently but I may give Resurrection Remix a try with Flash. If I had more time, I'd flash every ROM with every kernel to get a feel for all the possibilities LOL. :good:
For me Franco and flash kernel are the Best.... Now with ob3 with Franco kernel
Enviado desde mi ONEPLUS A5010 mediante Tapatalk
Did the Franco improve battery or performance? Someone Tried the Boeffla?
At the moment, both Flash Kernel and RenderKernel are great options in my opinion. I have tried most of the other kernels on xda and if you are looking specifically for smoothness/speed, these are the two you should test first. I do not run battery cycles; everyones daily use scenario really differs too much.
Flash Kernel currently has some kernel features I need (Kcal support & wakelock blocker) while RenderKernel does not have these features quite yet. While it lacks in some features, RenderKernel is undoubtedly the smoothest kernel for 5T right now.
I am on a 5T with OOS 5.0.3.
I like Franco but recently some custom ROMs have WIFI cannot turn on problem after I flash Franco kernel.
:fingers-crossed:

I haven't really played around with Kernel choices much.
I use and appreciate the professionalism of ElementalX kernel.
With it's options to adjust for extreme brightness, it quickly became a favorite a couple years ago and I've just stuck with it since.
Now most devs are adding high brightness to their kernels.
I guess I can start checking other kernels out.
I do like that ElementalX stays very stockish, reliable.
I can pretty much flash it and feel confident nothing weird will pop up over the next few days.

ElementalX, Franco, and flash were all my go-to kernels back in the 6p days (just a few months ago, lol), so it's hard to pick, especially since they all ended up on the 5t. Right now I'm on exkernel though I am partial to flash. Battery life is amazing on all 3, but the overclock on ex just adds that extra bit of smoothness that I've never experienced before. Call it placebo but I just love this kernel (exkernel).
any more input?
im curious to know if fsync affects battery performance at all, can someone also test this out if you are on a kernel that enables disabling the fsync feature

Technically it should improve performance when using the phone, but it won't be noticeable.

Does flashing a custom kernel solves Google play services battery drain?
Do I need custom recovery and root to flash a custom kernel? I'm not willing to play with kernel adiutor so I'm not really interested in rooting

Custom kernel has nothing to do with google play services. You need custom recovery to flash a kernel, but most kernels for op5t are "flash & forget" which mean there is no reason to change the setting of the kernel.

maybe not Google play services specifically, but with my latest phone (zuk z2), kernel was directly related to deep sleep
stock OOS/kernel has a serious issue with Google PS in terms of deep sleep. Besides that, I dont feel any need to flash a custom kernel. SOT is incredible already, and performance is really fluid.

If you are OK then there is no need to flash a kernel. If an app is crap (like Google services or facebook) the kernel can't do miracles and its not kernels job to control wakelocks of user apps
