Root Overclocking Limit?

It hasn't been reliably tested in a scientific way. I am sure plenty of people have anecdotal evidence one way or another. I haven't seen anything that tests it long term, or uses anything but the phone to test it.
 
To overclock you will need a overclock kernel for the ROM you are using, CM7, Stock, or MIUI. The highest clock speed on most up to date kernels is 2GHz, but you should do some trial and error. Find a min and maximum clock speeds that is right for you, good battery life but enough speed for daily use. Every processor is not the same, but 1.5Ghz and below is pretty safe clock speeds, 1.6Ghz and above might be unstable(more often random reboots) for some phones(every processor is made differently).

I would agree you are probably right that 1.5 or so should be OK to do safely. BUT....

There hasn't been any long term testing of it in any way using something besides the internal temp sensor. To really know for sure there has to be some testing done with the correct tools and all of that. Really all we have now is guesswork and anecdotal evidence (i.e. rough testing done using only the phone, like I stated in my first post).

If you want to guarantee that your processor won't be fried, it is best not to overclock at all right now. As there is no guarantee that it will be safe at any speed if you do. Although it is probably safe to overclock it a bit.
 
We assume 1.5Ghz is the thresh hold because of the majority of triumph users that random reboot at 1.6Ghz compared to 1.5Ghz, and also looking at 2nd gen snapdragon stock max clock speed. Though the likeliness of your processor getting fried is unlikely for a normal overclocked android user, unless you are doing crazy(double the stock max clock speed) clock speeds. Example, to long on 1.8Ghz - 2Ghz, when our stock max is 1Ghz...

I agree (I run mine at 1.4), but like I said it is all guesswork and the OP asked specifically how high they could clock it without damaging the processor. We don't know for sure. Even if the chance is small it is still there. I'm not trying to argue or anything, just making it clear that we only have decent anecdotal evidence that 1.4-1.5 is usually safe. Also the phone isn't that old, so there are no long term tests and I don't think many have been done in high temperature (i.e. it's freaking hot outside) situations.
 
Like everyone else said it just depends on your phones hardware. Mine runs great at 1.6 Ghz but if I raise it to 1.7 or higher my phone goes crazy. Wish I could run at 2Ghz consistently though :cool:. Alot faster then most dual cores.
 
Just like in the desktop PC world, overclocking has diminishing returns too. CPU isn't always the bottleneck in a computer system. It still has to wait for memory reads/writes to complete, or network speeds & ping times can affect real world performance. Having higher clock speeds could just mean it's spending more cycles waiting around for another component.
 
Smh at you guys. I can't overclock my OV to 800 mhz without it rebooting immediately. Guess that's one of the magical wonders of the triumph. :D

I came from an OV so know what it's like, 800 Mhz on the MT is faster than 800 Mhz on the OV still since the MT has a more modern architecture CPU and built on a smaller die size (so it's more power efficient too) :D
 
If you're going to overclock, don't forget to undervolt. I'm going to test each frequency above 1024 MHz to see what the minimum voltage is for each. It should be safe to be left overclocked if it's at least undervolted. As long as you don't have the processor min on 1.8 and max on 1.8, you should be fine. I'm going to make a new thread with my tested minimum undervolting values, and also monitor the temperature for each frequency to see any changes, if any.
 
I started playing great little war game and crashed after about 10 mins. Gonna go down to 1.5 for now. Didn't even think about under volting. Your thread some be interesting thou.
 
For playing music and surfing or whatever other minor task, it is stable at 1.7 or 1.8. Now when the 3d games come out, that's a different story.
 
I installed the no frills CPU and the Max is 1.024 GHz is that the highest it can go I know they were talking about going 1.5 or higher... were is the kernel I can flash the I can use CPU settings

This is the Kernel for MIUI

http://androidforums.com/triumph-al...oc-v1-5-kernel-tickerguy-cm7-11-19-build.html
This is the Kernel for CM7

Just flash these zips in clockwork like you normally would to anything else,after you flash these kernels there should be more options in cyanogenmod settings> Performance >Cpu setting,although you will need to install no frills-cpu or set cpu in MIUI.

I also have an overclocked CM7 and Stock ROM kernel, and there is a Speed Demon kernel for MIUI that are all using the same overclocking tables.

They are all listed under kernels in the root guide I linked. Check them out and decide for yourself.
 
on my defy i used a program called milestone overclock which requires root of coarse and i could overclock the processor to 1.2Ghz and a vsel of 80 which is still stable
