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.

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.

V14 kernel

I started this thread because i want to be able to use Sparksco kernel v14 but it freezes when its set to 1.0GHZ I been running v10 as my daily kernel and its bottomline on my top list of kernels. Any help will be much appreciated, im on the latest nightly CM255, i had to revert back to v10 because i need speed to check emails and surf the internet...If theres another update for the V14 in the future i hope that can be a fix or its probably my setup that prevents me from reaching any higher speeds, overall Sparksco you the man!!! By the way ICS devs yall get mad props peace...

I use sparks v14 kernel on cm nightly 255 clocked right under 1ghz using smartass governer no problem. I did a full wipe of everything, and formatted system before install of everything of course. Edit: I clocked it to 2ghz and no freezes here. Did you do a full wipe before the install of the ROM/kernel?

I'm going to have to give that a shot homie...

Kernel v14 is more geared for battery saving. I haven't updated the voltages yet because I'm not compiling gingerbread anymore, rather been working on getting a stable ICS rom build before I do more work on it. As soon as we get ICS gingerbread will be a thing of the past. Kernel v14 works good for some and v10 for others. I like v14 because of the battery I've been able to get on 122mhz min and 998mhz max. But if you up the min to the next highest setting (230mhz) you shouldn't get any lockups. Or even try 307mhz.
Edit: looks like 307mhz min is the only clock speed that allows me to overclock to 2ghz and not have any lockups. I'm also on cm nightly 255 pzguzman, and I always keep it on smartass governor.
P.S. The mods should be able to move this thread no problem without removing the comments or thread.
Sent from my PG06100 using xda premium

Yeah, forgot to mention as sparks said, at 2ghz the min is at 307mhz.

Oh okay i see Sparksco thanks for clarifying the setup, i dont mean to steer anybody in the wrong direction especially from working on a ICS BUILD which is the most highly anticipated OS for android. But im going to flash v14 and try out the setting and will get back and let you know thanx homie...

No luck but its amazing how you guys achieve the speeds... Tried the settings but my phone cant handle the pressure lol...Im gonna stick with this kernel tho... My bad for posting this thread in the wrong section its a rookie mistake...

It worked i only needed to do a full wipe, thanx homie...

By the way Sparksco i got your setup on my rom, fully functional overclocked at the max with no feezes, thanx homie...

YOU'RE USING THE WRONG GOVERNOR MIN/MAX SETTINGS
For example:
IF I want to get 2ghz out of my phone I use the performance governor and use min/max of 2ghz.
OR:
I would use:
Gov: Smartass
Min CPU: 300mhz
Max CPU: 1.5ghz
You would freeze too if you were a CPU constantly going from 100mhz to 2000mhz all the time!

Smartass2 was made for the HTC Sensation which is a dual core gsm phone much like the Evo 3D (but cdma instead). I could never get it to clock passed 1.4ghz so I don't think it likes our phones much. It's a great concept but the normal old smartass still works much better for the shift.

FWIW I am hitting 2.0Ghz with no lockups or anything. I previously had been using ScaryStable for a while and anything past 1.6Ghz would lock right up nearly immediately.

Again, it depends on the governor and the min cpu. I ran scary stable at 1.9ghz for 24 hours+ straight, no lockups.

for the heck of it I ran it @ the min of like 1something hz for the low and 2.0 max just to see how it ran, and it was solid.

I understand but say you ran scary at min 100mhz and max 1.9ghz with a gov of ondemand, that would freeze for sure on any phone.

Quadrant scores!!!

Hey guys with all the quadrant scores being posted everywhere, I haven't seen a topic dedicated to these alone. So that's what this thread is for. Here are the rules:
Rule 1: when you post a quadrant please tell everyone what Rom/Kernel you are running so if anyone wishes to follow your steps they may do so.
Rule 2: Please merge your posts if your going to post one after another or simply edit your post and update it to maintain order.
That's it. Thanks guys and here is my quadrant. AOKP 40.1 devil .97 with v6 super charger and kak

Hey azuma how did you get your CPU so high? Also I need you to test something for me. Antutu tels me I'm pulling over 3200 in a quad. But quad pro tells me just over 2600. I'm unsure which to believe

Seems like you started this thread so we could show off each of our own tweaks and roms. I came here for a little advice too. That way I could see some big performance increases to my phone.
(first screen capture)
old rom: AOKP 40
old kernel: devil .79
old CPU governor: smartassv2
min-max frequency: 200-1400
(second screen capture)
Current rom: AOKP 40
Current kernel: devil .79
Current CPU governor: conservative
min-max frequency: 100-1400
I was curious I used the ROM setting built into the AOKP rom to set the cpu frequency, but should i use devil kernel config or manager or nstools. or is that just for live OC? My cpu frequency is set at boot. My quadrant scores are pretty low. Any tips for a noob?

Yeak I got a couple for ya.
Go to settings, Developer settings, then put a check mark in Force GPU Rendering Make sure the Max CPU is 1400 low is 100 Governer I have set to conservative, ZRam is set for 100mb. Try those settings and reboot before you test again

Ok I believe the Force GPU rendering definitely made the biggest difference. My 2d and 3d scores jumped up. I updated my post. For some reason in the ROM controls it took a couple tries for the new cpu and governor settings to stick after reboot.

MunkyDrunky that still seems a little low considering what everyone else is pulling. Try this as well. And I'll include the files from my phone when I get to my computer with instructions.
Get if not already had toolbox
And go to performance and SD card boost. Change the value to 2480 (I think it is. It will give you a preferred high set)
Go to app manager and freeze any constantly running services that you would normally use such as yahoo mail Facebook etc. And use the mobile web versions to help save ram. I'll include v6, 3G, and a few other files you'll need as well.
After the SD boost and app freeze reboot phone into recovery and wipe cache and dalvik. Then reboot and try your test again.

I should say my running apps are usually not many. Right now its Rom Control, Android keyboard, Maps, Nova Launcher, and Rom Toolbox, and Superuser. I test my gps a lot with Maps. Otherwise I dont have a lot running since this isnt my daily use phone. I want it to be again but want to get it flying first.
Thank you for the good advice and help. Trying SD boost now...will try v6 and 3g speed boost later

I use v6 supercharger, sd boost, and app quarantine while at 1300 MHz and I still only get around 1500...I feel like that's pretty low for AOKP MS6 with devil right?

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

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.

I'd be careful about recommending a kernel where the developer is doing so blindly. Honestly its very irresponsible. Unless he's got a device that's 99.9% identical, i cant recommended it.

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.

I'd be careful about recommending a kernel where the developer is doing so blindly. Honestly its very irresponsible. Unless he's got a device that's 99.9% identical, i cant recommended it.

As someone who is using Franco's kernel at the moment, I can recommend it strongly. It's running very well :good:

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.
