Flyer is running Senseless v4 HC 3.2.1 rom (based off Virtuous Rom) and it is fairly smooth but would like to try and speed it up as fast as possible and still remain stable.
Question #1: The rom is packaged with an HTC kernel (assuming stock). Is this capable of being overclocked or do I need a custom kernel such as Leedroid?
Question #2: If/when I get the proper kernel to allow overclocking does anyone want to share their SetCPU settings? Or recommend a different way to overclock?
Because of the age of this device just want to milk every last bit of speed from it until it dies.
A month and no reply. *BUMP*
I am now on oc 1.86/384 smartass v2 leedroid kernel. Going well ve not experience kernel panic and no overheating. Have not tried any higher as this is good enough. Cheers

1) Stock kernel will not allow you to overclock, you need a custom kernel.
2) Every individual device and processor is different. By definition, another person's CPU may be capable of certain overclock speeds, where yours will not (or vice versa). For that reason, another person's SetCPU settings aren't going to do you much good. Just start stepping up the CPU clock a bit at a time, and use the device for a while and see if it functions properly with no errors. Just like overclocking anything else.

Thanks for the reply.
Problem now is it looks as though the rom I have currently is packaged with the a stock HTC kernel. Cannot find a working link to either Leedroid's HC kernel or any other custom kernels.
**EDIT...NM, link is working now. Go figure**

I know for the droid there are lots of custom kernels that use very low voltages for high speeds. Do we have custom kernels like this?
The processor in our phone is that of the original 2g/3g iPhone, the 528mhz Qualcomm (that should have been updated 3 years ago).
The processor in the Droid is the same as the iPhone 3gs (except 550mhz clocked instead of 600mhz).
The Droid processor has a floating point co-processor (sort of) which is why the Linpack scores are WAY higher than ours (it doesn't actually mean the phone is faster, it just does certain floating point operations faster).
The Droid processor is also SEVERELY underclocked, probably for power reasons. There is more of a demand in the Droid crowd to control power usage while still increasing speed (hence the low-voltage kernels, etc). "Lower voltages" are found by using different ways to multiply the frequency, but in a processor like ours, we are limited in the different speeds we can multiply (not to mention a ceiling of reasonable operation being usually 800mhz or below).
See, some people want their droids to be at 800mhz. They want that great battery life, to keep things cool, and a small performance boost.
Some want to go up to 1300mhz, maybe because they play games, or because the think they're cool, or whatever. That requires different methods for overclocking (depending on which exact speeds) and uses a lot more juice. You could use a 1300mhz kernel and keep it down around 800mhz (or whatever specific speeds the kernel allows), but that kernel might not be built for low voltage - you might just be still multiplying a number that keeps your voltage high, instead of the 800mhz Kernel that only goes so high, but keeps things easier on the battery.
Our Eris processors are more limited. Pretty much, you want your Eris OC'd (usually to the 700+mhz somewhere is all you get), or you don't. If you don't want it OC'd, you just don't install SetCPU. If you do, you install and use it (or whatever other overclocking app/widget you want).
To use your Eris low voltage, you pretty much need to stay 480mhz or lower. I keep my sleep SetCPU Profile at 122mhz-480mhz. VERY good on battery, and it throttles up to 480mhz (so the phone rings faster) when it's time for a call to come in.
Some Kernels have some things enabled (netfilter for wifi tethering and other things, a2sd enabled, overclocking, etc - depending on how it's put together). It's probably best to have a kernel that allows everything, since with our processors, there's not much of a power drain penalty (none that I know of in fact) for having a different kernel, and just running at 528mhz. I notice no battery difference at 806mhz in fact, it's a matter of having SetCPU profiles (or whatever) set up correctly and effectively.
Here are a few Kernels you might find (but most are incorporated in ROMs already, so you'll virtually NEVER have to flash it - except that I use Ivan's Eris_Official 1.0 ROM with zanfur's beautiful v3 kernel - it works perfectly at 806mhz on my Eris).

The point is that for us, it's not that useful to flash kernels. Most of the ROMs you'll download (even the most 'basic' ones) have all the goodies enabled on the Kernel.
Different phone, different hardware, different ballgame.
God damn. Best answer I could have hoped for. Seriously thanks a ton man, that was everything I could have wanted to know thoroughly explained.
nvm. answered my own question hah
I'm on Conap's new CFS Kernel. I multitask a lot so that's the kernel for me. Everything feels more responsive. Like 1.5x the responsiveness from the (I think) BFS kernel nonsensikal comes with. I typed all of this without even a hint of lag.

I appreciate the work being done on o/c kernals, but coming from Droid X, there where some great o/c apps that where easy to use, and could change voltages on the fly, making it easy to get the most out of a stable o/c. Will there be such a thing for the TB?
Setcpu.
Coming from droid2 I know what you mean, but we didn't have a custom kernel so were had workarounds. Which is why you had to change once already booted. Not sure if this can be done on tb.
I assume its probably better to havea custom kernel than setting after boot.

I have setcpu, but that doesnt allow for overclocking, just clocking down from whatever the max of the kernal is. And AFAIK you cant change the voltage, but maybe Im mistaken about that.
I really like Quickclock advance, you could change voltage by % tailoring it to your exact cpu.

Um, sure it does... Assuming that you have an overclocked kernel loaded (the stock kernel is not overclockable), setCPU can control the overclocking of said kernel.
you need an overclocked kernel before you can use set cpu to overclock

Set CPU allows you to overclock if your kernel supports it. When you open SetCPU and then select "Autodetect", what it does is check which speeds the kernel supports and lets you pick that from the list.
I can't talk for everyone but a LOT of people (including me) use SetCPU to overclock.
You said you came from the Droid X, the kernel was not able to be changed out because of the locked bootloader, if I'm correct. That's where Quickclock advance came in, it was made to overclock the stock kernel.
On the Thunderbolt you can change the kernel with an overclocked one and use SetCPU.
I realize setcpu can overclock up to the max allowed by the kernal, what Im saying is an app that allows to go beyond that, and manipulate the voltage. I am running at 1.2GHz right now, it runs up to 1.5 fine, except when I get a call it will reboot. If I had a little leeway on voltage, maybe I could get it stable at 1.5.
It would be easier to just o/c in app, then try this kernal, change, dont like, the try another kernal....
No point to use a work around when we can use the real thing.
For the people that maintained root through the update; are you able to use an app like setcpu or something to underclock the newly overclocked kernel?
Why would you want to underclock it?

to improve battery live, but really undervolting would be more useful.
for underclocking, the companion core works much better and is very effecient for standby/basic use senarios.
undervolt won't work until we can flash custom kernels, which need a custom recovery to flash them, which needs an unlocked bootloader.
i don't think apps like setcpu know how to deal with tegra3's 4+1 core setup right now, someone can correct me if i'm wrong
My guess is that the UV/UC battery gains are going to be quite small with the ninja core taking the majority of the strain. There should be some kernel source from nvidia which indicates what the transition is from the different states - maybe the best gain would come from locking out the G processors.
I saw some LP <->G switching info in dmesg with a pre-ICS version, but it seems not to be there any more...
Well the reason I asked was because I'm one of the people who gets nothing but boot loops after the ics update. After trying everything, I was wondering if this could be done, which would narrow the issue down to a kernel problem.

Hello! i am in the process of overclocking my thunderbolt in order to get better performance with the eternity rom, and i was wondering what you guys oc your phones to? and if you do, what program/setting do you use to do so? (i plan to use a script in init after have found suitable settings)
I, personally, find it pointless to OC the Thunderbolt. The phone is fast and smooth enough for me on the stock speed, plus the battery life is bad enough without adding more strain to it.
However, if you insist on OC'ing, 1.2GHz is a safe bet. Some people can get to 1.4GHz, but then you run into freezing and random reboots. Also remember that individual phones handle overclocking differently. Where one phone can run perfect at 1.4GHz, another might freeze instantly when going that high.
Good OC'ing programs include SetCPU, No Frills CPU, and ROM Toolbox.
I don't overclock. That being said i have OC'd my phone b4 i have had it up to 1.8 Ghz stable, but it doesnt seem to make anything run faster. I use the Thundershed version of CM7 and its super fast. I dont think it could get much faster. and without overclocking i get better battery life.
thanks for the info actually ended up going with the lean kernel which is oc'd on the kernel level, works fairly well

Leankernel is tops. I use battsaver mode which is stock speed and undervolted. Smooth as butter on my phone.

I found a solution to fix the Doom kernel reboots for those who are unable to download stock roms from HTC (Rogers Customers). Requires CWM Recovery.
1. Download stock kernel here - http://www.box.com/s/7dc3bf2adc9e2f05b717
2. Unzip archive
3. Move Zip file to SD card
4. Reboot into bootloader fastboot reboot-bootloader
5. Flash the img file fastboot flash boot name.img
6. Go into CWM and install the zip.
This solved my problem, hopefully it works for you guys too.
This should work on ALL devices not just Rogers
it doesn't actually solve the kernel issues...
your just replacing him.
i still think his kernel has a lot more potential than the stock.
It fixed my issue.
I care more about having a functional tablet than a kernel that may have more potential but is buggy as hell.
i agree. and i'm running the stock as well.. just wished the doomlord one would work as well.
Hi there,
Noob user here.
I got HTC JetStream from previous owner with doomlord Kernel on it.
Tablet is constantly crashing for no logical reason which leads me to believe that the kernel is causing this issue.
I would like to flash back to the stock kernel only as my device (Rogers) is running a stock image.
I am having difficulties to follow your instructions.
Wold somebody be so kind to post more detailed process steps to complete this kernel flashing back to stock.
Thank you very much.
I had the same random reboots using Doom's kernel until i overclocked it to the maximum. It's been almost 2 weeks since i experienced any reboots....
Sent from my Inspire 4G using xda premium
could you be more specific?
did you set both the minimum and the maximum to the maximum?
did u change the voltage?
Yes I changed the min & max all the way to max.. not sure if it will have some long term effects on my tablet, but it's been working great for a while now.

lol... so the "solution" to the DooM kernel reboots is to not use the DooM kernel. Brilliant.
If I find some time this weekend, I'll try maxing out the O/C though and see how it goes, as I do find the DooM kernel snappier, even at stock speeds.

You do realize that by doing that you are running your kernel at max speed constantly which means additional heat, stress and wear on all systems?

No, it won't run at max speed constantly unless I set the governor to "performance" mode. In "interactive" mode, which I believe is the default, it will still clock the CPU at its minimum value until the tablet needs more CPU resources, such as when scrolling, loading a webpage, playing a game, etc.
But yes, I'm aware of the risks of overclocking. I've overclocked every HTC device I've had very few problems (my One XL has exhibited some bootloops, so I've stopped O/C'ing it.)

I'm running 1.83 ghz ondemand with also the lowest setting for the min freq setting. I will increase it to 1.944ghz ondemand as the max setting and increase my min setting to 756Mhz on deadline, and see if the reboots stop, otherwise I will have to install the stock kernal.
I am just wondering if I install the stock kernel on top of my OziMood rom, if this will cause Rom problems?
Any thoughts on this?

I have mine on max: 1.62 ghz , min: 594 onDemand and it hasn't crashed in two or three days. So we'll see. Now to answer your question, if you want to flash back to stock on that Rom you'll have to install the stock WiFi modules from recovery. After that everything should work normally.

Thanks for that.
So far, I haven't had anymore reboots.
Increasing the minimum seems helpful.
I get plenty of battery life, so I am really happy about this for now.
Just a quick update.
I've been running 1.944 GHz as my high setting and 756 GHz as my low setting for some time now and I have to say, no reboots, no lag, super fast and stable.
