newbie member here needing help with overclocking my evo. i am very familiar with loading custom roms but for some reason i can not find any step by step guides to overclocking. i am running the fresh evo rom with king kernel 9. i downloaded the supersonic zip and tried installing it from recovery, and my phone wouldnt reboot past the first "htc evo4g" screen. just kept rebooting into that screen. any help would be appreciated. and if i posted this in the wrong place there is no need for assholes telling me. im new here.
What was in the supersonic zip? What exactly were you trying to flash?
The easiest way would be to get setcpu, and then adjst the values.
Just get setcpu from the market. Overclock away.

As teh roxx asked, what was the 'supersonic zip' that you flashed? I am not familiar with it. Is it something specific to fresh's rom? From the point you're at now, your best bet will be to restore a nandroid backup (if you have one) to get you back to where you were before you flashed the 'supersonic.zip'. If you don't have a nandroid backup to restore, you're most likely going to have to re flash your rom, if you are indeed completely stuck at the splash screen. Have you tried wiping cache and dalvik cache, then rebooting agaain? If it just hangs at the splash, restore nandroid or reflash the rom. Thats basically the only option to ge t you up again.
And I don't really overclock at all, but I believe you just need a kernel that supports overclocking, and use an app like SetCpu or OS monitor to change the clock speed. Never check the setting 'set on boot' until you're sure that the changes you've made are running stable.
Just flash cm7 it has cpu governor built in

Why do you want to overclock your device?
In all likelihood, you should expect only an improvement in CPU frequency of about 12%.
However, you should consider what the potential consequences of that could be. Although there are certain tolerances included, you should consider that consistently operating at higher frequencies could negatively affect the durability and/or longevity of your device's CPU. If additional cooling were something that you could add, then perhaps thermal thresholds would not be an issue. Because smearing thermal paste everywhere is not an option, you should consider another option.
The advantage of a custom ROM is that in some cases it's designed with profiled-governors and absent bloatware that tends to prematurely drain your battery and decrease overall performance.
I am not convinced an increase from 984 MHz to 1113 MHz is worth being tethered to an AC outlet.

+1 on this. I've played with numerous ways, always seem to go back with just the Rom and the kernel.

okay, I used to use set cpu... then I read that set cpu actually kills your batttery, so I stopped using it.
currently i'm using VirusRom anthraX RC1 with 2.6.32.15-king-havs-OcUV-aosp
should I be using set cpu?
+1. also, the first time i used it, i oc'ed all the way and instantly got a reboot. is this the starting point in the infinite reboot cycle? i had that problem happen to my last evo.... not fun

bump, help us.
I am thinking the dconfig file virus has will work on Anthrax..use it on Airborne and REVolution roms of his, along with SetCPU, and getting good results.

Its entirely up to you. If you feel you phone isn't fast enough for you then OC it. SetCPU is required to overclock. If you don't overclock then you don't need setcpu. You will most likely have better battery life if you don't overclock. I run mine both ways I oveclock for a while then run stock for a while. Battery life is better at stock speeds.
My advise when playing with setcpu is to uncheck the set on boot just encase you set it too high. Take baby steps don't just jack it up all the way. Also I think some kernels can use a configuration file, I don't know anything about that.
I am currently on CM 7 with Tiamats latest non sbc kernel and am considering trying out Vipers scripts to improve battery life, but in doing so, hoping to not negatively impact the performance. I don't know much about what settings to change once I have flashed the script and was hoping someone could suggest what changes I should make (if any are needed, does the script automatically change the default voltages?) I get a little nervous changing things when I don't really know what I am doing. Basically, please let me know what to change to get the best battery life possible without noticeably compromising performance.

yeha just flash -25mv at a time. and then if it gets laggy I would just get into recovery wiper dalvik/cache and then reflash the kernel. Then get into vipermod and flash the last stable undervolt value.
i lowered by 50 mv and my battery life has increased so much and i dont notice a performance change
Ok, just to clarify, am I choosing lower all voltages by 25mv per time, or just choosing to lower the max voltage 25mv per time. I guess I am not clear on that part. Also, do I need to reset these values each time I reboot my phone? Seems to me, my numbers reset after a reboot, does this make sense?

Hello, glad to have another user. A few things... 1) We aren't that scary in the EVO thread, you can always ask questions there 2) If you go to my site, there is an FAQ that should explain everything you need to know. 3) You want to lower all voltages, that's the easiest way to do it. You can get more advanced and set custom values for min or max if you want. Your changes won't stick after a reboot unless you select "Save changes". I would recommend not doing that until you have played around with the phone after lowering voltages to make sure your phone is stable. What can happen is that if you lower them too much and save changes, you phone might run ok for a little bit and then freeze. Then, you will go into a never ending bootloop (solved by flashing the reset .zip on my site)
I hope this clears it up a little bit for you
In the past week have just rooted my inc2, flashed OMGB rom and Tiamat 1.1.0 kernel. I also loaded SetCPU from the market. I can't go over 1.036ghz without the phone locking up and having to do a battery pull. When the phone is back on I only have a few seconds to open SetCPU and lower the OC rate or the phone will lock again. I wiped cache/davlik cache before flashing kernel. What am I doing wrong? I have seen in the Tiamat thread in the development forum that people are going as high as 1.9ghz with out a problem. I would only like to get 1.2ghz to 1.3ghz because I read that this is a safe range. I do have have the governor set at Smartass. Thank you for your input.

Go back to the kernel thread look for the voltage table. The voltage levels are too low at the overclock levels, that what's causing your freeze ups. Use incredicontrol app from the market to adjust the voltage levels. You want to mirror the settings to match those of the previous version of the kernel

Thanks tnez, I found chads post about incredicontrol and sounded like it only worked on ver 1.0.4, will it work on ver 1.1.0 also.
How bad is this freezing for the phone? If I ever get really stuck will booting into recovery and reflashing omgb fix it or using the nandroid backup I created before flashing the kernel? Still new to all the rooting and custom roms and kernels, lots of fun but still have the fear of bricking the phone.
I'm fairly new myself but have been using SetCPU for a while. Make sure the "Set on Boot" option is unchecked until you find a setting that will work for your phone. As far as the nandroid, restore is your friend!! lol I've made many mistakes in the past that have totally locked up my phone and the restore option from recovery has saved me every time. There is always a chance that you can damage your phone but as time has gone by the devs have really made that possibility minimal

The app works on any kernel that supports adjustable voltages.
Both methods will work to undo things. Either restore or re flash the rom. But like stated above don't select the set on boot option until you find settings that work good on your phone.

Thanks again tnez, I installed incredicontrol and made the changes to the voltages so far so good. I have gone to 1.19ghz with no problems after the voltage changes. Is there app that can be used to test for stability or is just using the phone the way to test for stability.

You can do it by use....open up different apps very quick and switch between them...basically trying to over load the phone by making it multi task at a high level. set cpu also has a built in stress test under the info tab, run that for a few mins. I usually do the stress test for 3-5 mins followed by a quadrant test.

In regards to Tiamat, there have been a ton of people say that downgrading back to 1.0.4 Tiamat fixed the issue of the phone locking up when overclocked. If all else fails from what you have been recommended, try that!

voltages just need to be changed and made to match 1.0.4 for the kernel to run like a champ

Hi guys,
I'm a bit of a noob so please bear with me. I recently rooted my phone (SGH-I747M Telus), I have CWM recovery installed. I was interested in overclocking so I installed this kernel on my stock rooted rom (I installed the "sammy" one). I also cleared the delvik cache, cache, and fixed permissions before rebooting. Now I'm having a weird problem with video playback. I get these bleep like sounds, like you might hear on a spaceship, lol. The normal audio plays in addition to these sounds. Yet, regular audio plays fine (mp3s), same with youtube. So, my question is, why? Is there any way of fixing this? I'd rather not play around the stock ROM. I made a backup before doing anything and recently tried to restore the boot, but I got an invalid md5 check.
-JC
Okay, I was able to fix my problem by flashing the stock at&t kernel... but I would still like to be able to overclock... is there another kernel that I can try or a way to fix the problem with the kernel I already tried? Thanks.
If you still want to try previous kernel your problem might be because of heavy undervolting , kernel creator posted this voltage chart.
You can experiment by increasing voltage and see if that helps.
Or you can just try this faux kernel , its pretty good also, we don't have many kernel choices for Samsung based roms at this early development cycle.

Thanks for the reply... but I was able to fix the problem. It was something wrong with the settings of SetCPU which I installed earlier. I changed it from on demand to performance and now all is well. Now I have a question about battery life. Will overclocking drain battery a lot faster? I imagine it would only make a difference if I was doing CPU intensive things.

Well.. performance setting makes it so that your CPU runs 100% all the time. I don't think that will be battery friendly . Overclock generally uses more power and battery longevity will depend on your usage.
You can try messing with setcpu settings. Try Conservative, then limit minimum speed to 384 and max to your preference. Try your movie again.
Current kernels and setcpu are a bit quirky.
I had the same issues on ktoonsez Sammy. Ended up back at stock AT&T. I've heard it's an issue with many of the kernels but a fix is on the way. Couldn't find a way to get rid of it, but that's not to say it can't be done. Don't have much time to tinker right now.

Its a known issue on ktoonsez kernel. Flash faux's kernel, it has the same features (as well as GPU OC) and doesn't have the audio issue.
I am new to the whole idea of undervolting. I have previously overclocked my phone's but never undervolted. Is there a how to guide anywhere in the forums that i failed to find, if not can someone explain the steps and settings that they found stable on their phones with out a significant performance decrease. I am already rooted and have an overclock/undervolt kernal installed. I apologize if i missed this topic in a search.
Sent from my SGH-I747M using xda app-developers app
First step would be to go to the kernel thread and see how/what app should be used for the under volt/governor/i/o scheduler settings and install that. Different kernel makers may want you to use different methods.
Second, under volt settings will be different for every phone as the hardware is different. The best way is to take down every frequency 25mV at a time and do not use set at boot or any option like that. The reason for this is that you need to make sure your phone will be stable. If you set at boot and go too far and your phone reboots, you may be stuck in a boot loop and have to reinstall your ROM. After trying your phone for awhile and it seems stable reduce the voltage again and try it out continuing these steps until your phone becomes unstable/reboots/lags then raise your voltages the next step up. Try again for a bit and if all is well then you can utilize the set at boot option.
Remember every phone is different, only lower your voltages till what is good for you, doesn't matter if someone else with same ROM kernel can under volt further, they just have different hardware.
