What are the reasons for trying different Kernels? I have Flashed to Darky's 7.5 and I am not big into playing games on my phone just basic Calling,Texting some simple games. Are there some Big advantages I could benefit from if I OC/UV with different Kernel?
Thanks

Overclocking will make the phone faster and undervolting will give you better battery life as you crank up your processor speed but both can mess with your phone as you get toward extremes on both ends. Overclock too much and your phone goes crazy. Undervolt too much and you get sleeping death and stuff like that.
With the type of user you are I would recommend xcal's kernel, a 2.2.1 rom and do not enable the lagfix, which I believe Darky's rom fits the bill. You will not notice a difference in performance and you won't have to deal with an issues relating to oc/uv. If you are a hardcore gamer then you might need to oc but I play asphalt 5 all the time with neither and never have any issues with lag or stutter.

Thanks for reply. I just love to tinker with things so though I will probably not fool with changing Kernel now I am sure I'll get the itch and try it once to see how I like OC and UV at some point......
Thanks again
I would suggest glitterballs kernel, it is based on 2.2.1 source, uses voodoo which you can choose to disable, and is oc to 1200 but you can opt not to oc. I find it to be very stable

I am getting ready to Flash Darky's 7.7(I have 7.5 now). I think I read that 7.7 has Voodoo enabled when you Flash(before you had to Disable Lag fix to get Voodoo). Will glitterballs kernel work with 7.7 and Voodoo already installed? Also is this the the glitterball you talking about?

Speedmod kernel that just came out is good and snappy. Its a battery sipper too!!! And no OC/UV.

I have read that a lot of guys really liking Speedmod but if I read correctly you can't have Voodoo running and Voodoo runs with Darky 7.7 Flash automatically. I am sure there a way to disable Voodoo in 7.7 I just need to find out how. Or I can be completely wrong about SpeedMod and Voodoo.

Yes, the kernel is still based on the i9000 JPX source release. Hopefully we get real source soon.
Main Features:
NEAR STOCK BATTERY!!! (Thanks Morfic!)
Overclock up to 1.4Ghz.
BLN (Backlight Notifications).. A basic app is included to turn it on if you want it
Voodoo lagfix v5
Voodoo Sound v4
Many parts of the "speedmod" patch from the i9000 forum
OC is based on raspdep's OC patches, also from the i9000 forum
Various speed tweaks
CIFS/SMB and NFS support compiled in (no modules)
Tunnel support compiled in (no modules)
Changes since 3.2:
New boot logo. (Thanks Alexia!)
Added battery drain fix in standby discovered by Morfic. Should be about the same battery as stock now.
Voltages and frequency scaling have been adjusted to more quickly jump to higher frequencies and come down slower. Improves response time while you use the phone.
The Voltage Control app has the correct voltages, I recommend leaving the lower speeds alone to start with. Going too low can cause the sleep of death. That's why they are as high as they are. NOTE: The voltage control app does not control the available states they way the older ones do. That screen is useless, ignore it. Set your max and scheduler if you wish, and the voltages if you want to change them.
SetCPU.... If you want to use it, you can have it set min/max. If you set profiles, don't set the max under 800. The phone needs 800 to be available. I use a screen off profile at 100-800 just to keep the OC disabled while sleeping. No reason it should need to really crank up the speed if I'm not looking at it. SetCPU is NOT required, I'm offering this as a tip for fans of that application.
The kernel has proven stable for a number of testers so far. If you get crashes, disable any OC/UV settings and try again. I recommend you only change one setting at a time, and NOT set at boot until you have run for a while to ensure you can run stable at that voltage/speed.
Great job testing it out now. Edit: screen is a little dark but the kernel is super smooth

I am considering flashing this new kernel but have a couple of questions I would like to ask first. I am currently on Bionix V 1.21 and love it. Is this kernel compatible with Bionix V 1.21? It appears that this kernel is Voodoo enabled so I presume I would not have to disable voodoo. If I decide to go back to the Kb1 with voodoo enabled which I believe is the stock kernel for Bionix V 1.21 would i just flash the kernel( is is available on TW forum?)or would I have to flash the whole rom again? I would think I would not have to but want to be sure before I leap. I would not like to have to ask for help for problems that could have been avoided by reading and asking questions. Any and all help is greatly appreciated.
Is it ok to not use set cpu? Will this kernel will oc over 1000?

Im not sure if you have to disable voodoo or not .. probably not but don’t take my word for it and no you do not have to flash the whole rom again, just the kernel. Thanks for not clogging up the forums. Lol I know its hard to ask questions in the vibrant forums, (cause you'll get beaten to death with mean comments) but ask them anyway, someone will answer eventually. Ignore the whiny, ungrateful 2 year olds that somehow wandered onto this forum...

It is compatible with Bionix 1.2.1, that's what I developed it on.
If you have the red voodoo recovery, there is no need to disable voodoo for flashing. Generally speaking, kernels can be flashed without disabling voodoo in any case.
This is what iv'e done, I've lowered my Volts on some clocks, 1000 and up, and I was wondering should/can I use setcpu for profiles?
Answers to COMMON questions:
1. Can I flash this over Voodoo or RFS (stock)
You do NOT need to disable Voodoo. Flash right over Voodoo or RFS kernels. Make sure you are not running JFS though. JFS is not supported
2. How is stability? Does it crash? Sleep of death? etc?
Stability on this is AMAZING. It will not crash unless you overclock/undervolt and your settings are unstable. If that is the case, you know its your settings.
3. Do I need SetCPU to overclock?
You do not need to use SetCPU (You can if you want to). Use the Voltage Control App to overclock.
4. How do I overclock? Can I use this without an overclock?
By default, the kernel will boot to 1.0Ghz. To OVERCLOCk to 1.4Ghz (or lower) you need to use the app that this kernel installs during the flash. The app is called "Voltage Controll" and can be found in your app drawer after the flash
5. What is the battery life?
Battery life should be close to stock now. The battery drain issue that was present in the I9000-based kernels earlier has been solved.
6. Does this support BLN (Back-light-notificaations)?
Yes. You need the BLN control app from the market to use it.
7. How do I use Voodoo sound? What is it?
Voodoo sound is a vast improvement to the sound quality of your phone. To use it, download the Voodoo Control app from the Market.
8. What ROMs is this compatible with?
This is compatible with ALL Vibrant Froyo ROMS. This means 2.2 ROMS made for the Vibrant. 2.2.1 is not yet tested but should theoretically work.
I hope this helps.

You can use setcpu for profiles, just keep 800Mhz available. The phone will likely crash if you don't. I set a screen off profile of 100-800 to keep the oc disabled when I don't need it, as 800 is a lower voltage.
Hint with voltages, try to keep 1000 and higher at the SAME voltage. Changing the voltage too often can cause instability as the voltage regulator doesn't adjust as fast as we would like sometimes. OC makes this worse as you need a higher voltage to maintain a stable CPU at the higher frequency. The kernel is set to jump to 1000, then to the max set clock speed. Setting 1000 to the higher voltage gives us some extra time to stabilize the new voltage before the just into the OC speeds.

Thanks for your kind words and the donation. I'm glad you find my work useful.
just flashed this..
and a few questions ive never used OC before..
What does VOODOO Sound really do?
I set my thing on SetCPU as 1.4ghz as max and .1 as low with conservative.
then a profile with screen off and on conservative.
will those save battery?

SetCPU by itself will NOT overclock. You need to use the Voltage app that comes with the kernel. See my above post with the Common questions.
I'd like any of the kernels developers gave me a clue about an issue im having with all custom i9000 based kernels (eugene's and TW's). The problem is with line2 voip app which calls isn't heard in the other end when running these kernels, but in stock/voodoo it works just fine. Please any of you have an idea of what could be going wrong?
thanks.
Okay tested so far, everything is working good (undervolted to about 175 for lower clocks 100-1000 and 75 for higher clocked 1200-1400)
Don't try this, as every phone can't handle some things, i'm just stating.
EDIT: I'm seriously stupid, how do I remove the settings again? I know it's in system/ something
Edit: NEVERMIND fixed
I've never used an OC kernel, was thinking of giving it a try. If I decide its not for me is this like removing a voodoo injected kernel, disable, then flash a diff kernel then delete files?

Hello to everybody who has taken the time out to help me with my question!
Thanks to the devs also that make this happen.
Ok i have been elsewhere since i have gotten my UK gt-i9000 (playing with cfw on ps3)
i have since returned and thought i would give it a go.
i would like to know what kernel i can use which will push my i9000 to the highest oc frequencies as i am only finding kernels that are limited.
either a kernel with no limit to oc
or mabey a the highest known kernel
Thanks for your help guys
Don't mind helping you out here
KERNEL][VoodooSnd4-VSF-OC-TRCU-BFQ-ZRAM] Super Optimized Kernel 4_8_1 STABLE [02-28]:
OC frequencies (1200-1300-1400-1500-1600)
this is the highest possible as far as I know.
if you want true speed in 3d games go for darky 9.4 with damiangto
his new beta kernel can go to 1280, which should be enough for most people. Together with some undervolting, your battery keeps some juice left and your phone stays under the 45 degrees.
post of the kernel: http://forum.xda-developers.com/showpost.php?p=12331961&postcount=3069
His normal stable kernel goes to 1200 mhz, which can be considered safe. and its still really fast.
So far my advice
1.2GHz laststufo's 4.8.3
Hello,
So im willing to try some kernels for my Nexus to see whats the best for my needs.
I want to compare the stock kernel to the leankernel, franco kernel and the ElementalX kernel.
Comperasion criterias:
1. Faster booting
2. Fastest performence as possible without hurting battery life in comparison to the stock kernel.
3. Better battery life as possible without hurting performence in comparison to the stock kernel.
So how can i compare those kernels? should i just flash each kernel and use AnTuTu Benchmark and Better Battery Stats on each one of them?
Choosing the best kernel for me is to give a try for each one and see for myslef - i know that. But i want to see the stats in front of me to reasure im picking the best one and also beacuse iv'e used the chroma and euphoria roms which use leankernel and franco kernel but im not sure the difference is noticeable by eye.
Also, feel free to share your current kernel and opinion about it

1. Stop watch
2 & 3: Not really possible. To give to performance, takes from battery and vice versa. You give 1 to performance, you take 1 from battery. There are no magic settings that allow you to give 1 to performance and only take 0.5 from battery.
I hope the attached image helps to explain that
There are also other things to factor like the governor, scheduling, hot plug support , etc.
For example elementalX has its own Governor and I'm not sure it will even default itself to be used. You will need some type of kernel configuration tool to enable it .
There is also how YOU are using your phone. Just too many variables to consider

Yeah for sure.
I always say that because kernel x performs more than kernel y out-of-the-box, it doesn't mean you can't set kernel y up to perform like x... It's just a trade off whichever way you go.
My personal advice is find a kernel that has the features you want, then configure the governor with the bias you want to see. I always go for Elementalx. @flar2 sets the best balance of battery and performance in my opinion, though I always alter my settings to suit my needs anyway
