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

Looking for some battery life here. What would you recommend?
Sent from my HTC Vision using Tapatalk
Honestly, with the stock CM kernel I stretch out 18 hours easily with heavy usage (non-stop texting )
That is of course with NO profiles @ 806 MHz using the ondemand governor. If I need more power I just simply crank up the processor, no need to stay OCed all the time
With that said, 806 MHz is perfect, I experience no lag at all. So there really is no need to stay OCed at 1.5MHz unless you want to kill your battery
Hehe, I actually love you for UPGRADING from a crap NS to a G2

I got some lag on ADW EX at the stock speed, so I decided to melt it away with buttery OC goodness. I'll actually see how it lasts today, and if it's killing me I'll try clocking down until I get something acceptable. I was just wondering if there were any especially good UV kernels or anything of the like.

What kernel did you end up going with?
I use pershoot's kernel and get pretty good battery life for being overclocked at 1.5ghz.

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

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.

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.

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.....

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.

I posted this in the AOKP thread actually. I saw it fly past my twitter that it was updated for GalaxySII but figured it was for the international versions, or for that matter just non-sprint. But I updated it and it does indeed allow overclocking.
Yeah, pretty freaking sweet....cant wait to see how much more I can get out of the battery now.
I'll be even more excited when we have the source for the kernel. I would like to see some more governors available, such as Smartass. The three we have available, User Space, On Demand and Performance aren't really spectacular, though they do the job.

I subtracted 75mv from all of the voltages. So it is undervolted by 75mv. Definitely seeing longer battery life than yesterday, but the rom was also flashed yesterday, so it might just be settling in.
I have had numerous kernel panic lockups and spontaneous reboots trying to use tegrak at speeds and voltages that were perfectly stable on 2.3. I even tried to go a little higher on voltages. Still reboots. Think it just isn't ready for primetime yet.

Calkulins roms have the battery saver script in them that controls the CPU clock. Even if you over clock on Calkulins, it will go back to whatever his script says unless his script allows the app that your using to overclock.
His script disables if it sees any other app that controls cpu.

I would see absolutely no need to overclock this phone, but I can definitely get behind undervolting at stock speed. Neato.
just installed and oc'd to 1.3ghz, and undervolted by -75 for each frequency. Also, somewhat weird is that no benchmark shows a second core. Does AOKP not use both cores?

for undervolt if it is sysfs HAVS enabled you need to get vipermod. If it just says undervolt then it may have a pre-set undervolt determined by the dev.

On GB is was running this same setup and my battery life was nothing short of amazing. I had a good 15-24 hours depending on use.
best cm7 kernel?
i just recently started using mason. its pretty awesome. before that i used tiamat sbc also no problems. just try which ever ones you think you may like every couple days to see which one works best for you. i also give the kernel about 10 minutes to bake in every time before i unlock it. i dont know if thats been proven to help but it cant hurt and seems to work well for me.
I've been running mason sbc for about a week now. I had to use a combination of vipermod and smurfed out scripts to get the kernel set where I wanted it. I noticed the kernel was set for BFS by default, which I've never been a big fan of, due to its power consumption....so smurfed out let me set the scheduler to CFS, which is much more conservative and doesn't sacrifice any i/o speed, imho. Then I used vipermod to uv -25MHz so it wasn't such a battery-hog. Underclocked, undervolted, and set to CFS seems to be my winning combo!!! I get no less than 3 hours of constant screen time (streaming video, browsing the web, etc.) and enough standby to last me all day so I don't have to carry my charger with me anymore.
With every other android I've ever owned, setcpu does everything I've mentioned changing in this post...so when it wasn't working, I had no idea what to do.
Thanks so much guys!!! I couldn't have done it without all your help....HTC is in a world all its own in the android scene since they use so many different things that no other manufacturers do. It made me want to pull my hair out until you guys came along to help me out
