I've been on the TB for about a year now, coming from a Samsung Vibrant...one thing that I've always had questions about is how to properly OC a kernel especially on the TB. I've used Imo's lean kernel and i usually just set the kernel to a stable 1.4 through Terminal Emulator. However, I would like to used Ziggy's kernel on Skyraider Zeus and i'd like to know if there are any guides on the forums or online that can point me in the right direction as to how to properly OC while keeping things stable. I've looked online and google'd like a fiend but I can't find anything definitive that I can keep coming back to. Any help would be greatly appreciated guys.

Hi
I'm wanting to build myself a custom rom for my HTC Evo 4G that's main purpose will just to be fast. I already know how to theme, but when it comes to making a rom faster I'm lost. I'm planing on using teshxx's RUU 3.70.651.1 OTA 2.2 Froyo stock rom as my base because I like Froyo more then Gingerbread.
I was wondering if anyone knows of any guides about making fast roms? I know using the rom kitchen and zipaligning the rom is one way to speed it up, but I'm looking for other ways.
I searched XDA but was unable to find a thread about it, but maybe I didn't search hard enough. Well thanks in advanced, all answers are appreciated.
It's not like you can flip a switch on a ROM to instantly make it faster. The ROMs that are faster than stock took a lot of work to make them that way. Kernel patches, optimized code. These aren't simple things.
I run the Evo myself. The fastest ROMs I've found for it are Salvage-Mod and CM7. They're about the same in speed, but Salvage is a little more "bare". CM7 has a few extra features that Salvage hasn't integrated (like different lockscreens and T-Mobile theme support).
You can try a different kernel. Tiamat and Savaged-Zen are both good. And you can try CFS vs BFS. Some phones don't run BFS stable for some reason. On my phone BFS gives me a noticeable improvement on responsiveness.
Right now I'm running Savaged-Zen 2.2.0 BFS with CM 7.0.3, using the SavagedZen governer at 128-1190 MHz, and it's about the fastest combination I've found so far.
I'm struggling to recognize the benefit of a custom kernel on prime.
Also, Revolver has piqued my interest. I've seen other posts that are similar to this, but not quite as detailed as i'd like.
What does a custom kernel bring you? I have Prime 1.8.4 and haven't even really recognized the difference between in and the stock firmware.
Please be patient, i'm new to the Android OS.
So, to rehash, im looking for information on:
The benefits of Prime.
The benefits of a custom kernel + prime or revolver.
The benefits of Revolver.
Revolver + a custom kernel.
I'm appreciate the fact that you guys may not have time to indulge a noob like me. If anyone can help me find the resources i need, i'd greatly greatly greatly appreciate it!!!!
The guides & how-to's on this site are amazing, and i realize that most of this stuff is geared toward developers (i plan on developing, and have just begun my studies. I shall be as amazing as you all one day!!!) but i'm missing quite a bit of information. Few of the guides i've seen speak of what the software actually is/is intended to do/be, or how it's different.
P.S. If anyone has any idea if there is a ROM/ Android dev wiki, i'd appreciate the location of it.
If not, i think ill start one!
I saw a thread that kinda talked about what a kernel is, but I think, for me, I use Clemsyn kernel because it allows me to overclock (overclocking at 1400~1504 atm) up to 1600ghz. That lets your tablet run faster than the factory setting (which sets it lower for less chance of a burn out). Other than that, I don't really know either and I'd like to hear some replies too =D.
its basically similar to the benefits of a custom rom. it lets you...
1) overclock
2) adds support for kernel modules like ntfs, cifs, 3g.....
3) can allow for optimizations
clemsyn is always playing with bus speeds and memory timings to squeeze the most performance out of the tablet. he also adds modules and functionality like the poster above said.
I like custom roms because they do awesome things, like compile tun and cifs support into the kernel. now, i have been on prime for some time, but a lot of things seemed to be a little snappier over the stock rom.
i don't bother overclocking.

okay, im new to the inspire but i have an honest question for those of you who are very experienced with the hardware and available linux kernels for cm7 on the inspire/DHD.
Please dont turn this into a quarrell of sorts, what im looking for is A. which kernel do you prefer to use whilst running cm7 on your inspire? B. why do you prefer this kernel over stock, or the other available kernels for our devices and C. are there any specific features that are available/active in the specified kernel that led to your decision.
I know how to read OP's, and I have read the OP's of both kernels mentioned here (BUUUTTTT please feel free to mention any compatible kernel with cm7 in this thread) but there are a lot of good/cool things going on with every kernel it seems, my main problem is i havent EVER seen my inspire lag... so i have nothing to compare performance to other than my galaxy s i had prior to this inspire that i had to tweak for weeks to get running half as smooth as ANY rom ive used on this inspire.
I'm currently on nightly 252 running TalonACE with the v6 supercharger script set to my usual setup (like 72mb ram is the highest oom value with the HTK launcher or die-hard launcher or whatever he calls it now) and I dont know what to do with myself! My phone is running so well that i cant figure out anything to flash to "improve" on anything because it seems this phone runs... well.. perfect all the time!
One more thing, if anybody has gotten ShadowGun (tegra2 optimized) to run on any particular kernel without freezing the phone (using CF3D of course) please share the CF3D settings used and kernel used to achieve such, my crappy laggy captivate could play shadowgun smoothly for hours with pretty much 1/2 the ram and power of this inspire and I would like to actually get it to run longer than 2.5 minutes
any and all input encouraged!
Threads like this will always lead to a flame war on which is best. That is why they are not allowed.

Why is the overclocking area on my Captivate greyed out after installing cm9 latest nightly???
I honestly do not have the time to read hundreds of pages of forums to see if someone has allready had this issue.
Of course i tried searches.
It happens on any cm9 nightly, not just the latest one.
I want to be back at 1.2ghz. being stuck at 1ghz. is rediculous to me after being so spoiled. (lots of google earth, gaming and other stuff that a higher clock speed helps with)
If I have to I will just go back to 2.3.7 and a swift 1.3ghz. MAX
BUT it seems like I should be able to overclock using CM9 on my captivate.
Please do not explain the system settings and performance yadda yadda yadda, anymore, i am obviously familiar enough with an android device to know how to use system settings etc. if i can root and install custom roms i can read and point and click as well.
Sorry for the frustruation but i seriously can not deal with anymore nonsense and 80 diff. pieces of broken info from people that only "heard from some guy" about how to do all this.
Thank you in advance... forever learning"!"

Were you using Glitch before, or some other custom kernel? I didn't think cyanogen's stock kernel supported overclock. If you install a new nightly you have to reinstall your overclocking kernel.
I have been using cyanogenmod only. I never purposefully installed a custom kernel then the rom. Just used Odin to root/clockwork and so forth. Never heard of Glitch. Through out all of my custom rom experiences with the captivate I have been able to use the sys. settings or osmonitor to overclock to a max of 1.3ghz. I have tried miui or whatever its called for about five minutes. other than that just cm6/7, then updated to cm9. in the past whatever kernel i had, stayed in effect, i guess.
I will do a search for custom kernels for cm9 on captivate.
I havent seen any yet, but who knows. I am used to simply stunning roms and the moto droid one. That was great! SS/chevy~ would always have links to the latest kernels avail. for the current builds etc. Good job too.
SO... the search continues.
*Mystery: If I cant even change cpu settings in osmonitor (up or down), yet it lets me enable root mode, what does that mean? The greyed out overclocking area in perfomance settings (up or down)???
I need to learn more"!"
As mentioned, glitch kernel b6 is a great ics kernel. Flash over CM9 and install nstools from the market to control all the kernel settings such as oc/uv, voltages etc etc.
Sent from my glitched ICS Captivate using XDA App
The options are greyed out because the stock kernel currently doesn't support overclocking. Glitch is awesome, and Semaphore kernel is pretty nice too.
Sent from my CM9 ICS i897 Captivate
IcyGlitch for OC, and Semaphore for 400MB mem.
Well Glitch has 387 MB of free RAM
both kernels are good
I want my 13 MB! They are unused so occupying them is unforgivable. IcyGlitch is solid kernel, and I hope 400MB will be added.

I recently rooted my Mytouch 4G Slide (s-off) and have been trying out several roms, my favorite of which are: Blue6IX's Bulletproof rom, Virtuous Primadonna, and Virtuous Inquisition. I like all of these, since each have their benefits over the other. Bulletproof is more solid and maintains the ability to use all stock features, most importantly the camera. The Virtuous roms are both visually more exciting (Inquisition is an ICS style rom), BUT the camera crashes if you even try certain camera features or some random things fail like trying to send a photo via text. All those pros and cons aside, the main feature keeping me on Virtuous Inquisition is the overclock kernel. It overclocks up to 1.7Ghz, and that's damn cool if you ask me.
Since the Virtuous roms have so many issues, I want to be able to use a rom like Bulletproof and still be able to overclock it. I looked all over this forum for overclock info/kernels and found just 2 threads. One was an older one by Romanbb called Kanged (still available for download), the other was from Blue6IX including several variations of kernels (but none of the download links exist anymore).
Then I did some more research on the kernel used in the Inquisition rom. Everything I read pointed to a developer that, apparently, only has overclock kernels for the HTC Sensation (can't think of his name at the moment). This seemed a little strange that a kernel for a different phone would be compatible with mine.
So this is where I reached a dead end with even more questions than I started with:
Are overclock kernels specific to each device? In other words: if I found one for a Sensation or whatever, would I be able to use it with my MT4GS?
Since Romanbb's "Kanged" OC kernel seems to be the only one still available for the MT4GS, would it still be compatible with newer roms? And for that matter, does is have to be used with a particular version of Android, or Sense vs ICS?
You see, I don't know enough about overclock kernels (or even kernels, themselves) to know all the right questions to ask in this situation. All I know is that Bulletproof has the stability I want, while Inquisition has the speed I need. And before I go cutting & pasting bits and pieces of one rom into another, I'd like to know what I should be doing or if I'm even on the right path. So maybe someone can point me in the right direction and help me to understand compatibility of oc kernels & how they can/can't be implemented. Also, where the hell do I even find oc kernels for this model of phone?
Thanks in advance to anyone who can help me to understand all of this. And I apologize in advance for any headache my abundance of questions and lack-of-understanding may cause.
All of the ICS/JB roms that use the v3 kernel by TeamDS are overclocked to 1.7ghz as well. Oh and don't flash a Sensation kernel...you wont boot. Also I'm not sure but I think the latest bulletproof (v1.1) has overclock to 1.7
Edit btw this belongs in the general because this is a question

I'll check those out. I've noticed there's a common trend between all ICS roms for the MT4GS: they all have the same camera failures as well as plenty of other random issues, although some have more than others. So I'm hesitant about trying any ICS roms older than a couple months, since it seems that a truly stable ICS rom for this phone with minimal issues doesnt exist yet. But yes, I will check it out.
As for Bulletproof, if it does have overclock then something is wrong because I tried SetCPU (several others as well) and I wasn't able to set a max frequency higher than 1200-ish mhz (or 1100 something?). No matter what I tried the frequency stayed at stock settings. Thats why I'm trying to find out where to find a compatible oc kernel and how to install/flash it on top of a rom that didn't originally have an oc kernel.
With the Virtuous Inquisition rom that I'm currently on, it allows a max of 1728mhz which is great. Although for some reason whenever I set up a new profile within SetCPU or even change the Min/Max settings, the setting doesn't have an effect on the actual frequency longer than a couple seconds before reverting back to default. And I tried disabling Perflock but I get "Error: Misc Exception.. ". Which brings me back to my original thought about the kernel used in this rom; I found the name of the dev and kernel version used in this rom: "SebastianFM -Sensation 3.0.13 kernel". When I looked up that guy's kernels, they all seem to be exclusively for the Sensation, but his kernels are being used in this Inquisition rom that is compatible for the Sensation, Evo3D, and MT4GS. So the fact that this (apparently) is a Sensation kernel might explain why my settings in SetCPU have no effect and I'm unable to disable Perflock.
Still though, it would be nice to get the best of both worlds; stable rom, fast-as-hell kernel.

Thanks. Didn't know that, I figured this was a development-related question so the "Development" section made sense, and I made sure I labeled it with a "( ? )" to avoid any confusion. My mistake, I suppose. And although I've been a long time reader of this forum, I didn't set up an account til last fall and hadn't actually started a thread til now. Now I know. Soo, is there a way to move this thread and I'm just not seeing it?

No, you are not allowed to move threads, even if you created them.
The post was reported, and the thread moved. For future reference, you can do this as well - but also for future reference, no questions should ever be in the Development section. Thanks!
