Hey all. I'm using Xtreme Kernel and SetCPU and I'm wondering what are decent limits to downclocking and overclocking the processor. 1.3 GHZ is the SetCPUs max, but I feel 100MHZ would be too low to downclock to. would 300-400 MHZ be a good downclock limit? Specifically for low battery life profiles?
I shoot for 200-300mhz at the low end if I am running > 1ghz
Phone runs flawlessly with 200 at the low end. 100 causes too many problems.
Are you using a stock kernel to overclock or underclock or a custom kernel?
I was uable to find kernels for this phone.
Are there any?
Thanks
There were several different custom kernels for 2.1.
Can you name a few of the best ones and are there any for 2,2
Xtreme Kernel its the kernel I'm using. I many by limit as in high end limit. I ended up just trying it and 400 mhz is useable for low battery profiles.

Hi, im just about to flash leedroids 2.2.3 rom, which can oc to 1.8 ghz with setcpu, just wondering if there are any dangers in having it at this speed? anything to be aware of ?
It might fry your device, it might not, you never know. There's no need to run it at 1,8ghz. I'd recommend max 1,2ghz for daily use though everything runs smoot at 1ghz already.
If you overclock to 1.8Ghz you will increase the risks to fry your CPU(and hence, your device will be destroyed). Lol.
Also overclocking too high can drain your battery real fast. As per Hawks556, max 1.2Ghz would be fine.(perhaps it is almost to optimal)
I overclock mine at 1.16Ghz and it is already very smooth in LeeDrOid.
You may sometimes wish to overclock it until 1.8GHz is just to show off to your peers only. Maybe through quadrants. But later on make sure you underclock it back.
Cheers. =)
thanks for the help, lol whole thing just froze while i was reading it better underclock it lol : /
OC up to 1.5ghz should not harm your device.
Take a look at ths HTC Flyer: it has the same CPU as the DHD but it's set to 1.5ghz by default.
So there is no risk in overclocking up to 1.5ghz in my opinion.

I am trying to get the best battery life out of my device, but I am unsure what the best settings are for the kernel I use. I am using Chads newest from June 27th. Should I leave the kernel running at the stock speed 998 for max and then 128 for min? Or would you save more battery underclocking the max speed? If so, how much should one underclock it to?
Thanks for any help.
Your best bet is try different settings. I set my min at 128 and max i'll set it at the lower 900 or mid 800 settings for normal use to save battery life. If im playing a game i over clock it.
Using 844 max myself and never had an issue playing games. I've seen others underclock in the 600-700 range too. Just see how low you can go without sacrificing stability.
I'm running KT747 (Build 3/14/13) and I'm just wondering what this stuff is and does it affect my battery/performance, and if so how? Thanks to anyone that can help!
Overclocking speeds up main processor past 1.5ghz, kernal must support this function. Underclocking slows processor speed to whatever you set maximum under 1.5ghz. Under is good for saving battery, but can cause lag depending on how you use your phone. Governors control how the processor handles requests, such as opening an app, with on demand gov, processor ramps up quickly, with lagfree gov, processor kinda takes it time, which in return saves battery. If your not comfortable or understand this totally, be careful, search for guides on xda about overclocking and governors. Overclocking can cause bootloops, freezes, or other issues. I overclocked mine to 1.7ghz with no problem, but I'm running Agat kernal.

I am using ElementalX kernel on stock 4.4.4 android. I have to OC set to 1.944GHz currently. AnTuTu bench at 1.944GHz and 450MHz GPU gives me between 24-25k result. Now if I lower the CPU to 1.89GHz it drops to 21k. And if I go back to stock freq I get 19k. Something does not seem right in the test results as related to the frequencies. Question is this: Are there sweet spots in the frequency range for the CPU?
P.S. I know many people dislike benchmarks...I'm using it for comparative purposes...

It states it in the thread, having cpu at 1.9ghz is not economical with battery consumption and performance, it Is best at 1.7ghz

You should monitor your CPU temp and frequency while benching.
You would see that your CPU's temp probably goes above 70°C if not higher and so the kernel thermal throttling policies would downclock your CPU's max freq. in order to keep your CPU "cool".
If you first bench @ 1944MHz then bench @ a litle lower frequency and have very lower score then its not because of the lower freq. but because you did first heat up your CPU @ 1944 and when you re-run @ lower freq. your CPU is already very hot and so does a severe thermal throttling.
Last point : running your CPU @ 1944MHz is not good since thermal throttling while happen every now and then.
Not convinced?
Then simply launch the camera app and try to take a video of 5 mins...your CPU will become so hot that it will downclock to something ridiculously low and your recording will become jerky.
Hey was wondering if anyone knows off by hand the lowest we can undervolt our phones @ stock freq or what our stock voltages are? I undervolted mine recently and got amazing results but stability seems to vary, using overclock freqs @ 1.89 running @ 1.087 mv 1.83 @ 1.05mv 1.78 @ 1.0375 1.7 @ 1.025 mv I seem to be fully stable pulling 28905 scores on anutu, my friends s4 isn't even this fast was very impressed phones not even hot at all, but I really want to try to tweak the lower freq to help with battery life/temp
solution to the battery drain problem
Overclocking the CPU frequency will lead to battery drain as u know it yourself....don't download any of the battery savers as they are useless .....try Greenify....bcoz it works....and it just is too awesome.....
Undervolted and got these results with anutu, impressive, looks like undervolting gets good results
Stock Speeds 1.7ghz -> 1.050
Barely over Stock 1.78ghz -> 1.075
Mild overclock 1.836ghz -> 1.0875
Higher overclock 1.89ghz -> 1.100 (highest anutu score)
Pushing it 1.944 ghz -> 1.250 (yielded a score the same as 1.89ghz)
what kernel were you using here and ROM? thanks
