Over heating problems while over clocking?

How can I reduce over heating while I overclock?

Cpu profiles are about your best bet bro. And reducing needless overclocking.

.... also the UV (undervolted) kernel in the dev forum SHOULD reduce overheating.

Even then speeds over like 1.2ghz begin to get overvolted for stability. Also, none of the current GB roms have a dedicated UV kernel even though the stock one is very close to pershoots from what I've been reading (haven't looked at the voltage tables myself).

Oh right,... I assumed it was UV'd straight through,... but that makes sense that it could fail at higher clock speeds when UV'd. Let us know your findings if you take a butchers at the 2.3 kernel.

How hot is too hot in your opinion?

I have a profile with warning tone and underclock to 768 if it hits 40 degree. Thats Celsius though.

Kernel 2.6.32.27 – OC-UV-NEON_FP (1.516GHZ) – G2
-based off of HTC's vision-MR-2.6.32-g9ab3677 (developer.htc.com) and supplied vision_defconfig (2.6.32.17)
-merged up to kernel.org's 2.6.32.27
-merged in coolbh3k's oc patch
-frequency range is from 806 to 1516; default bootup is 245-806.
-undervolt all frequencies (max mv is 1300)
-merged in zinx's GAN_ETH wifi calling module modifications
-merged in a few changes from cyanogen's github.
-optimisations based off of .35 release from Nexus/DS.
-added/amended a few things to the config (-xtra (please see below and in github)).
Note:
This is a Work in Progress. Undervolt/Frequencies will be adjusted over the next coming weeks, as well as merging in further optimisations/tweaks from the DS/Nexus .35 release.

Experimental kernel with the BFS scheduler for the custom rom 160

I'm not responsible to any damage which is caused by applying this kernel (boot.img) to your phone ！
I've built a new kernel with BFS scheduler which is created by Con Kolivas (http://ck-hack.blogspot.com/) by patching genokolar's overclock kernel source (http://forum.xda-developers.com/showthread.php?t=1059029).
I've tested this new kernel on my phone, I'm running the custom rom 160 which is created by stockwell (http://forum.xda-developers.com/showthread.php?t=1059753), so far I'm quite impressed by the quick responsiveness of the phone even I set the cpu clock back to 800MHz in conservative mode.
Unfortunately the WiFi is not working, I hope later I can do factory reset to see if that will fix it, anyone willing to give it a trial and let me know the result is very appreciated !
Please note you may need to wipe the dalvik cache after install and reboot several times.
Updated : 2011-Jun-16
Looks like firefox adblock plus block my upload file.
I've tested this kernel several days, it works quite stable for me as long as you can boot it up, there may be a pop up says that system is not response during boot up, just ignore it.
There two things I found so far...
1. wifi is not working
2. battery drains out faster and warmer, I guess that's relate to overclock, if I set the clock back 800MHz, it seems ok.

What's the profit with a Brain **** Scheduler?

Cm7 uses the Bfs too.
Wikipedia says that that is speeding up the responsibility from your phone.
Sent from my Desire HD using XDA Premium App

But will it serve good purpose ?
What happens if they add a bogus algorithm instead of the brain **** one?

as soon as wifi is working i can try it and report bugs (if there are any)...

CM7 does not use BFS. We decided it was too buggy. It causes all sorts of instability on the Blade and other devices. Probably has a similar effect on the U8800 after a while

Using wiki as reference isn't the best.
However seeing that it does some bogus at points where the active thread of a normal priority process wants another time slice, and in ready block there is a lower priority process who wants a brief time slice it gives the time slice to the active thus allowing stupid **** ups. I guess its not good at all ?

Some good patches to add might be BFQ and the smartass CPU scheduler. Both seem to be stable and have good performance on my Blade and my Wildfire

Lol why sorry? Just clarifying that while CM may have used it in the past, no official CyanogenMod ROMs include it

BFS404 is pretty stable and I've been running it on my kernels for about a month and I have no complains, everything runs smooth, fast and battery friendly.

[Q] Why is Stock rooted so much smoother than CM7?

I've found that stock 1.3 rooted is a lot smoother in scrolling animations and such... Will CM7 ever attain this smoothness? Yes, i have tried both overclocked at 1.2-1.3 ghz

What version of CM7? Was it an SD card install?
Sent from my LG Optimus V using Tapatalk

I've noticed the opposite, as long as cm7 doesn't have too many apps installed.
Sent from my NookColor using xda premium

What sd card where you using? Not all are made the same.

I've used 7.0.3, 7.1RC1, and nightlies between around 140-165. All emmc

I don't deal with stock so can't tell how smoothness it is but it's a good sign.
If you like rooted stock ROM then go ahead and use it.

I like CM7, but I like the smoothness of stock. The bad thing is the missing features
Sent from my SCH-I500 using XDA App

I have the same problem. My theory is that CM7 is just missing hardware acceleration on the nook at this time (I think I remember reading this somewhere). Maybe a driver issue?

I thought they had that worked out in the first stable release? Maybe that was just video acceleration
Sent from my SCH-I500 using XDA App

Video is fixed, but that my be a different part of the driver.
(This is entirely speculation on my part, based on my somewhat sporadic - and decidedly incomplete - knowlage.) My guess: there are 3 parts to the video "card" driver. 2D hardware, 3D hardware, and coprocessor functions. When they fixed video, they probably got the coprocessor functions working, but not the 2D or 3D hardware.
There is a good chance I am wrong, so correct me if you know.
On a side note, why cant CM7 use the video driver from the stock FW? It's still a Linux kernel underneath so shouldn't the drivers work, or am I missing something completely?

That makes some sense, but games(at least angry birds haha) work okay... So I dont know.
On using the kernel from stock: they probably can't use the stock kernel, because stock is based on Froyo, and CM7 is Gingerbread

Almost none of the stock rom is open source. I'm pretty sure the stock video driver was never released.
On the topic of smoothness:
I have found CM7 to be much smoother than stock. It probably just depends on your set up.

I just installed 203, and its definitely faster. its nice to be using cm7 again. I missed the status bar. Its quite a bit smoother than the last time I used it. I can also see all apps in the market now, which is sooo nice

Everything is running great, except for the YouTube app. It isn't working for me on nightly 202 or 203

Can you post a link to this V6 super charger script?
Thanks!

UPDATED 03/21 [KERNEL] ~GamerZ Kernel~ [CPU-OC 2157MHz & GPU-OC 320MHz]

~GamerZ Kernel~ ​
By installing this your warranty is now void... wait a sec, wasn't it already void? Hmm...
Okay, up on my soap box for a minute:
Don't expect to be able to set your CPU to a ridiculously high clock and then every thing work right. I cannot tell you what the limits of what your CPU can handle are, because they are all different. I do however recommend keeping it at or under 1914MHz to avoid any RR's or FC's in the middle of your game. If you attempt to OC more than your CPU can handle your TouchPad will freeze up and restart with the default of 1188MHz, and don't worry it's still okay!
UPDATED:
Okay, I've updated the frequency tables with some new frequencies and lower voltages for better stability and battery life! I've also now updated the 2D and 3D GPU to 6 scalable frequencies including 2D frequencies up to 270MHz!
This is DEFINITELY worth the update!
Right now:
29 CPU Frequencies:
192,384,432,486,540,576,648,702,768,810,864,918,960,1026,1152,1188,1344,1440,1512,1566,1620,1674,1728,1836,1890,1914,2022,2103,2157
3 GPU Frequencies: (3D 320 & 2D 270)
More features to come in the far future...
How to install:
1) Download
2) Boot into Recovery
3) Flash
4) Reboot to GamerZ and set your desired frequency

could you make your kernel so thats it support NTFS usb mountin alot of devises suppourt it and i know its only a kernel issue for our TP i would be awsome continue you exellet work love your kernel finally a good kernel for our TP

Weird, no matter what I do I can't get the kernel to take. I'm on the latest fat n creamy, I boot into twrp, install the kernel but it doesn't take. I've installed a million things and am no stranger to this whole thing so I don't get it. Any ideas? I downloaded the CM9 file twice, no luck.

How will a custom kernel benefit me

What will a custom kernel do for me. I have been thinking about rooting but I do not want to flash a ROM. I am really loving stock. How will a kernel benefit me. I heard they have something to do with battery. How is that?

With a custom kernel you can do some really cool tinkering for example
- underclock (save battery)
-undervolt ( MAY save battery , but will def help with heat)
- change governor ( may help battery)
- change screen properties . I.e colours
- GPU over clock / under clock ( obvious)
Other cool performance tweaks as well

I'd go with franco's kernel for now.
All of them are new and may have bugs, but franco is a longtime kernel developer and he's the least likely to do stupid stuff or claim features that actually hurt performance or are just placebos.

Franco's kernels seem good. I use it on my N7, but I just wouldn't use it yet as he's working blind. Faux has some amazing battery saving kernels. Mathkid's kernels pretty well as well, I used to use his on the Nexus S back in the day.

Under clock can be done on a stock kernel just needs root. Custom kernel allows over clock doubt its needed though CPU is fast enough.
Different governors can be used on stock too but custom kernels may offer extra ones like smartass etc.
They may also add things like NTFS cifs run etc not available in stock.
Using Motleys kernel just now too soon to comment on improvements.

If stock is working for you, there's no reason to flash another, unless you have the itch.
The stock kernel is great, and undervolting is more trouble than it's worth if you're starting from scratch, unless tinkering with voltages is your thing, and there's zero need to overclock the N4 CPU or GPU IMO. There aren't a ton of options, yet, either. 3.4 is pretty young yet.

Agree. Franco is amazing and once he actually has the device he will only improve.

Yeah -- that was my other experience, I'm using franco's kernel and have been since day one.
Quite stable at least so far, no crazy changes.
