I currently have a hero and my gf just got the EVO and the battery life is pretty rough on it of course like we all know but i just flashed an under-volt kernal and it seems to work very well, is this possible yet for the EVO? Here are the links below about the topic

Kernal for HTC Hero w/undervolt
http://forum.xda-developers.com/showthread.php?t=722073
AFAIK, most of the kernals we already have available undervolt the CPU.
okay, sorry im a noob to the EVO, as of yet i dont own one, i have a very good undestanding how ever thing works with my hero. So like the latest Fresh Rom for the EVO, has undervolt?

Fresh Rom is a ROM, not a kernel. The kernel that comes with Fresh Rom by default is the stock HTC kernel which has no undervolting. You have to flash an alternate kernel after you flash the ROM which will allow undervolting.
There are a few kernels from which to choose from available here.

There are several threads in her in the dev section here with various kernels for the hero. I use Damage Control 3.2.3 ROM and therefore use a kernel from the developers there. However there is another thread (not ROM related per-se) that goes deeper into the different kernels that are available and being worked on. If you prefer another ROM search those threads... Since the release of the complete source code recently several dev's are tweaking the kernels to integrate with their ROM's.
Seek and yee shall find... (If you go to the DamageControl link, Look for info on post #2. You will have to scroll a bit because it's a beast as is the size of the thread.
I think Baked Snack ROM does the most undervolting. He said he has undervolted it so low with stability.
That ROM does wonders to your battery... let me just say that.
I'm new to kernel flashing. I have been playing around with snap and kings kernel. I don't have a problem flashing snap, but once I have it installed it works fine for awhile, but then it reboots itself or goes into a state where it won't turn on and I have to pull the battery. I tried 7.6 both bfs and cfs and the same thing happens. I also tried 7.5 but once I flashed it nothing showed up in the apps to install.
For kings kernel I flashed it and it booted up fine but it seemed to freeze up and I couldn't unlock my phone after the boot.
Am I doing something wrong when I am flashing these? I am running the nightlies of cyanogen. Also, What are some other kernels that work well with cm?
Thanks!!!
Kernals seem to be a taste for the phone itself and not the rom...
My Evo doesnt seem to like any other kernals than stock I have tried many rom/kernal combos and the only way i get no issues and best battery is to run stock kernal
I ran fresh with netarchy and kings like some others-that had great battery and mine just drained fast so I am done with the kernal swapping for now and jut keep playing with roms.... Trying out Virusrom right now not bad so far
Try wiping the cache and dalvik cache before flashing the new kernels. That might help.
Another thing that might help is posting this in the right section. More people with the knowledge and good insight that you need will be more apt to answer you in the Q&A section.
I've tried clearing everything including data but it still would self reboot
the snap kernels do not work with the recent versions (nightlies) of CM.
The framework has been redone, and you will freeze.
You have to use the stock kernel.
Ziggy just made an AOSP kernel, but its buggy.
Toast has a .35 kernel that works good on the new frame work.
I just was able to use a different kernel of kings. It really doesn't enhance quadrant scores, but im want to see what it does to the battery. Where can I download toast.
Also, I noticed that now my unlock screen is different from my wall paper. Is that a kernel issue?
Check to make sure SetCPU is disabled (or any other overclocking utility), and wipe your cache/dalvik. If all else fails, go with the Snap 7.6 failsafe method.
Kings AOSP #1 has worked best for me using cm nightlies. I have easily doubled my battery life. Has anybody else had success with any other kernels? Is toast an AOSP kernel?
as TheJoker and drmacinyasha commented...
snap and king use the .32 kernel. snap http://forum.xda-developers.com/showthread.php?t=733099
cm6 nightly is currently using .34 kernel
Toast has a .35 test1 kernel available for CM6 (http://forum.xda-developers.com/showthread.php?t=735596)
ziggy has a kernel as well. (http://forum.xda-developers.com/showthread.php?t=819402)
zendroid has a kernel - http://forum.xda-developers.com/showthread.php?t=831021
turn off setcpu until after you reboot with the new kernel. don't forget to read the kernel threads OP for possible hints on setcpu configs (ie: snap7.6 works well with conservative governor)
yes they are all AOSP.
i would not advise a newbie to play with the snap or king kernels until the .35 revisions have been released. this is due to changes in the Framework.apk file. you are likely to find that a current CM6nightly w/ the snap7.6 kernel = no bluetooth. new kernels should be hitting shelves very soon. personally, i'm looking forward to loading up the snap kernel once its done cooking, i really liked that kernel.
most are just fine with the stock kernel
many have commented positively on the toast test1 kernel (aside from a hang issue at startup)
ziggy & zen have a bit of work to do on their kernels it seems.
once .35 is 'done' you'll find a bunch of movement on the the kernel threads.

Thanks! this really helped. This may be a dumb question, but where do you find out what kernel runs with the ROMS. eg .35
I really want to find a good combination that gives me good battery life and performance. so will snap 7.6 work with cm 6.1 rc 1 rom?
I saw for CM6.1 the stock kernel is the best. I have gotten the best performance, battery life, and bug free with the stock kernel.
Snap 7.6 would get stuck on the splash screen and required several battery pulls.
Toast .35 works good, but after about an hour or two for some reason it brings my fps cap down to 37, so all my scrolling and games run like ****.
Wait for Snap 9 or the official toast .35 kernel. Stock is just fine.
I was bored last night and tried cm 6.1 with snap 7.6 just for fun, but it seems to be working fine. The boot was quick too, it was on the cyanogen boot image for about 3 seconds before it started up. Quadrant scores are in the mid 2000s. No problems with anything else so far.
Is there a snap website or channel log? I can only fined directories.
Hi, Currently running Sense(less) rEVOlution 2.0 with Kernel #4, is there a better kernel for better battery life? I like this combo very much but I think the battery could be better
Also looking for a true senseless, AOSP gingerbread rom with gapps included, or at least flashable, any suggestions?
Thanks
Try lous #8....closest thing to whst ur talkin about would b skyraider athena, that and the other 5 gingerbread roms in development

If you haven't tried chad's incredikernel:
http://chad0989.dyndns.org/2.6.32.27-incredikernel-12232010-plus25v.zip
then I suggest you give it a go.
Use it without setCPU, at least at first. It has one built in so you really don't need one, if you find it too sluggish or you think you can set it better then put it on after you gave the whole Kernel a good run without it.
I find this Kernel very fast and the best for battery life that I've tried.

Not many of those. Really CM7 is the only one I've found worthy of flashing.
Try the RC1
(If you go with AOSP then you will need a different kernel than listed above)
Thanks guys for the replies.
I will try #8 tonight, also on chad's Kernels I have read the same and will be trying that one as well. I'm really liking Senseless 2.0 with Launcher pro Plus
Yeah I understand that with a sense rom you have to have a sense Kernel and with AOSP rom an AOSP kernel. Question though. IF i did decide to try and AOSP ROM, that AOSP rom should/would come with a new Kernel right? Just don't flash Lou's stuff/sense kernel after that.. only flash another AOSP Kernel. Is that right?
I have the Droidx so this Kernel stuff is new to me lol.. still learning.

You got it Most/all ROMs for the Inc come with a kernel included. I personally like the one CM7 RC1 comes with, gives me great battery life
Ziggy's 12111 beta
If I flash to incredikernel from Lou's #4 I just need to wide delvic cache correct?
Just tried Nil's Business gingersense rom. I like it. Doesn't seem to be as sanppy as CM 7 but maybe it will show the 3G bars correctly. I don't have enough posts to pose this question in the Nil's thread so I'll post it here. Can you overclock with this ROM? I know you can't use setcpu. If so, what is a recommended ROM?
No you cannot overclock, as it's the stock kernel. I don't understand the last part of the question, If so what is a recommended ROM...? Do you mean kernel? I know there were a couple of people in that thread the said Hydra's and someone else's kernel worked for Nils' ROM, but I haven't seen a post updating how stable/unstable it is.
Sorry, I meant kernel. I switched away from Nils' as it was missing a few features I wanted. I had CM 7 for a while but now I am back to Virtuous.
Once the GingerSense kernel source code is released, it's game on for custom kernels.
I hope I don't get flamed for asking. We all know that the stock Kernal is stable and seems to be working for every ROM. Can someone with more knowledge than I have append SBC code to the stock kernal so we can get some SBC lovin?
I believe they're working on it because the official kernel source just got released.
I think a lot of the work is being done to enhance the kernal by adding in UV, CPU governors, OC, etc, first which is pretty awesome, but I guess I'm just looking for SBC+ stock kernal.
