Undervolting Epic

Hello, I'm a noob with a quick question about undervolting. I am running SyndicateROM Frozen 1.0 EB13/EXT4 with the Twilight Zone kernel. I have the SetCPU.apk installed and I have some profiles and sliders set. I would like to undervolt to save some battery. Is this thing already undervolted? If so, is it only undervolted at 1.2GHz? Is there even a way for me to change anything relating to undervolting?
Thanks for any help.

Undervolting is something that needs to be coded into the kernel by the dev. The best way to save battery would b to use setcpu to a max of 1ghz. An overclocked/undervolted kernel will run at 1.2 ghz while using the same amount of juice that a norma kernel would use at 1ghz

and if they've done it right, which they have, 1Ghz will be using less battery than stock at 1Ghz. in theory the lower you set it the less battery you should use, but you dont directly change the undervolting settings, just the clock speed.

Much obliged.

I think that kernel only has undervolting enabled on 1ghz. So if you're on 1.2ghz it will only be overclocked without the undervolt...I think

I believe its undervolted at 1.2. Reason I say this is because I flashed the genecide kernal and set it at 1.2 ghz which I know is not undervolted on genecide only 1ghz is I believe and I got crappy battery. On the twilight kernal I'm set at 1.2 and getting great battery. That's just my observation so far.

I'm sorry, but you can't say that a great battery is caused simply by an undervolt at 1.2Ghz. The Twilight kernel, from my knowledge, is not undervolted at 1.2Ghz, only at 1.0Ghz. The great battery life you're getting out of the Twilight kernel is because of how it was coded and optimized. My 2 cents.

Twilight kernel is not undervolted on 1.2 ghz. Only 1.0. Read the thread

Overclocking

I would like to overclock my Dinc, I'm currently running skyraider 4.0 and have the stock kernel running right now. I wouldn't mind upgrading to a new kernel.. but all the ones I see give you about a 100Mhz overclock. This would be fine.. however I'm wondering if I could overclock to a potentially more unstable speed for a minimal amount of time.. are there any kernels that allow this? Also, what kernel would you recommend?
Thanks,

No kenel that i've seen on the inc have surpassed the clock speed of 1.2 ghz so no.

Why do you want to OC to 1.9?
Sent from an ice cream sandwich

For me the 1.9 ghz kernel is a bit unstable for every day use . But oc at 1.5cm kernel works much better and 100% sable and battery friendly if you use profile in setcpu.

Unfortunately, that varies by phone. Mine becomes unstable and 1.5GHZ

I have to say. If you gotta ask dont do it! Make sure you setup good profiles for heat or you run a serious risk of frying your phone! Good luck some people got lucky and have no problems running 1.9. My phone has no problem with that speed until for some reason i have yet to discover somthing makes it heat up at random times. After that happened a few times i decided 1.5 is plenty.

I thinks it's underclocked @ 1.9Mhz

Root the phone
Install ROM Manager from the Android Market
In ROM Manager, flash Clockworkmod Recovery
Also in ROM Manager, backup ROM ("nandroid" backup)
Download the kernel and put it on the SD card.
Flash kernel from Recovery
Get SetCPU or CPU Tuner to set the CPU clock
As already mentioned, if you want to OC that high, SetCPU profiles with temp failsafes, etc. are a must. You might want to start with lower CPU clock speeds.

kernel manager has it.

Yeah, it does. Unfortunately for me, it's stable for less than five blazingly-fast minutes Guess I'll stay at 1.5!

I think for a phone that was clocked at 800, 1.9 is far too risky. I have no factual basis to say that, just seems like common sense.
Sent from my HTC Vision using XDA Premium App

^I agree^ That doesn't seem logical....

I can't see OC our phones to 1.9 being good on any level. Seems like were trying to push the hardware a bit too far.

Is that how people are able to get Quadrant scores in the 2000+? I can't seem to get that high at all. I have been using pershoot's kernel with CM7...but now on nightly #91- using stock kernel now. I have been cautious on trying out this one...

Why would you want to clock it down to 1.9 MHz when the stock speed is 800 MHz? Even an XT-8086 ran at 5-10 MHz. An 8080 (the year was 1974) ran at 2.0 MHz.....

Lol, i think he meant GHz, typo =P..
As for quadrant, my DZ easily hits an average of 2100+ when OCed to 1.3GHz using Virtuous G-Lite 1.0.2. I really don't trust those benchmarks though, as long as the battery lasts and the UI is smooth, I can't really complain.

Well...ok, I was just trying to make sure I wasn't missing a step. I am happy with my phone's performance, so I will not be concerned about that anymore.

Bravo! I can't believe nobody else caught that.

1.9Ghz will sometimes cause my phone to either overheat or crash. I have it set to 1.516Ghz on Pershoot's kernel.

oc evo

Hey guys is it safe to use set cpu to oc evo? or what app would you recommend?

I use set CPU and it is safe to a certain point. If you overclock to far your phone will lock up and you will have to pull the battery. You have to experiment to see how far u can go. My phone is stable as a rock at 1152 MHz but gets llocked up at 1190 MHz so like i said experiement with it

614 mhz is the new OC! Try over clocking for sure but you see more profitable results under clocking. I do however use set cpu to OC when I am charging

Fellas,im looking to use SetCPU to OC my evo,i need a custom kernel i assume.two questions.
1.can i flash a custom kernel using the mount/unmount zip in recovery for my GodMode Synergy?
2.What Are Good Values,im trying to safely underclock to save battery life.

@gotheart, I strongly suggest freedom kernel by Lithid. There are bugs as it is in beta stage but he is an amazing developer and will implement an incredible kernel. He has one specifically for godmode so make sure you get that. He has versions that underVOLT the processor, using less battery. Though I would be cautious as some phones become very unstable with these changes.
Underclocking for CPU is variable... I like 614 MHz, some choose to go lower. I have noticed Sense ROMs (like synergy) are a bit more touchy with performance tweaks. For me, even in hot weather I need to bump my settings up, as my phone can't keep up with the heat.

Thanks so much man.i was a dev at one point..but i dunno jack about clocking cpu.lol.so youre saying 614,as in set the max value to 614 correct?and i sure will check out that kernel

Epic Touch 1ghz dual core or 1.5?

in my rooted room setcou and other tools shows the cpu as stock or base at 1.0ghz but will let me overclock it to 1.2 not 1.5 where it should be on stock rom it was stuck at one and on the sony ported one it will let me goto 1.6 but it get real hot and unstable at 1.5 whats the deal did we gt lied to on the cpu thats realy in the phone fior specs?

A stock Epic 4G Touch is 1.2 ghz.

It's 1.2 Dual core

thank you for some crazy reason i thought the factory specs was 1.5 but still dont explain why the os limits it to 1.0 if i didnt root it

T-Mo's is a 1.5 qualcomm, maybe that's what you were thinking of...

Sent from my SPH-D710 using xda premium

if ur running any custom rom with a battery saver script they most likely have it set to 1.0ghz sometimes even lower just regular usage i have it set to 800 and it runs smooth as silk ..if your not doing anything extreme you might never notice a difference by overclocking... actually im lying there is a deference the bugs that come with extreme overclocking not to mention the reduced life of your phone...but i think we're all guilty of overclocking just to do it.. and most of us just to brag about quadrant scores here's mine over clocked at 1.6 on performance with blendz rom but got really buggy

Very likely yes, although he may not know it.
