overclocking epic 4g - Epic 4G Q&A, Help & Troubleshooting

What is the safest speed you can overclock the samsung epic 4g? I am using the Tegrak overclock right now, and I found out the ultimate can run up to 2ghz.

That doesn't work. You have to be using a custom kernel to overclock the Epic and it is only safe up to 1.4ghz.

FYI, complete newb to this stuff, so please bear with me. Are you saying that it takes a custom kernal for the Tegrak Ulitimate, or the the version I have right now? With the Tegrak Overclock, I put it at 1.3 and it seems noticably faster.

Tegrak ultimate shouldn't work at all, and you're lucky it didn't royally screw up your phone without a kernel with support for overclocking. Look in development and select a custom kernel to fit your tastes then download either SetCPU or OverClock widget and use one of them to raise the clock speed on your phone. I recommend either of those because they are tried and tested methods.

Weird, on the android market it says that it (the standard Tegrak) works with stock kernels, custom kernels, and custom roms. I checked before installing it and I just double checked it now

For the record, it has been a while since I played with my phone, but it's kernel right now is 2.6.32.9

Another thought; I've had setcpu for a while, but didn't find much use for it as the phone is already operating at 1GHZ, which is the max SetCPU will allow the phone to work.

Because there isn't a kernel that support OverClocking installed.Once you have an overclock-compatible kernel installed SetCPU can raise the CPU speed.

I see. Thanks for the info

Also, while tegrak may work I strongly recommend a custom kernel for added stability, along with overclock capabilities up to 1.4ghz (depending on if your phone can handle it) undervolting and other useful features.

Each phone is different. Some phones can handle 1.4ghz, others can't even handle 1.2ghz. You just have to test it out and see what your phone can handle.

It seemed to hand 1.3 just fine, but I still backed it down to 1.0 until I get the custom kernel for it.

Thank you

After reading the link to Twilite, I am interested in running the SyndicateROM Frozen. Any chance someone could walk me through the steps? I'm not being lazy and am doing research, just want to make sure I don't screw up my phone. I am at work right now, so I haven't even attempted to get Twilite yet. Perhaps getting the new rom would accomplish two things at once??
Edit: After some reading I think I will be ok, but if anyone wants to chime in then feel free.

Here you go man! http://www.youtube.com/watch?v=Wy2Et6qVGdo
I made this video and it should help you out. The twilight kernel comes with the syndicate rom so you don't need to flash it since it already comes with the rom.

Is there any truth to a post I read stating some kernels support Wifi Tether and others don't?

[Q] SetCPU

My SetCPU has only about 3-4 different frequency options between 806Mhz and 245 MHz. Is there any way to increase the number of options between these two frequencies?

U have to root your phone and flash some ROMs depending on which type of rom do you like, it comes with kernels for overclocking or you can flash one if you want to. Rooted stock rom doesn't have any compatible kernels it breaks some stuff so you really need to use a different rom..

Well if he's using SetCPU then he's already rooted, so he's got that covered.
OP as jojo stated, you need a custom kernel to allow overclocking. A lot of people seem to be fond of Pershoot's OC kernels, but I personally just use the one thats included with CM6 and now CM7. It allows an overclock up to 1.5ghz.

I think he's wanting to know how to add more underclock frequencies. It can be done but you have to decompile the kernel in order to do it and also have decent knowledge of voltage tables (since the purpose of underclocking is to save battery power you have to uv also). Probably well beyond most peoples comfort level however, if the op still wants to attempt it are numerous threads with info - just search for something like 'creating a custom kernel' or 'make a kernal'. One of them is located in the G2 development forum.
Oh ok thanks guys. Yeah, I have Pershoot's kernel so that is not a problem. I was trying to include more underclock frequencies, but if that means editing or creating my own kernel then forget it lol, I'm no expert on that.

There's a turbo ROM that can deep fry your G2 to 1.8ghz, and it has a lot more frequencies below 806.

Cpu

Im good on everything else except when it comes the CPU thing. I have no idea what the numbers mean when you set the CPU for some reason. To slow the phones resources when the screen is off right? Can anyone point me to the direction of an app that can do this? What about an app that turns the data off once I turn the screens off. A free one. Thank you and sorry if Im not making sense or sounding dumb

SetCPU can modify the processor speed and allow you to set a profiles. However, you're running Tiamat so if you haven't changed anything your default governor is smartass which has a built in screen off profile of 128min/384max.
As far as turning data off, check out ultimatejuice. There is a free version that is limited in what it does, but it might be worth paying for. Also, for battery saving, check out my EVO link in my sig for some undervolting mods.
You can set the cpu governor with a program called setCPU on the marketplace. You can further control the CPU by flashing another kernel. What ROM are you running? Stock? I would try the netarchy kernel (newest version) if you're running a sense-based ROM.. I've found it has phenomenal battery life (medium use i get 15-20hrs) and I'm overclocked to 1.152ghz.
A program called tasker can also make your data connection go off and back on with the screen. I'm unsure how to set the profile but I do know thats possible. Try looking around here: http://tasker.wikidot.com You should be able to find something about it.
EDIT: Nevermind about netarchy, did not see your signature on your ROM and kernel.
ok, so ur on aosp and tiamat. try changing governer to smartass. will give you much better battery life, and you won't have to worry about 'numbers'.
btw the numbers are the cycles per second, or the speed the cpu works at. i personally underclock to 537 (998 is stock) to save a bunch of battery, and it still runs perfectly fine for me (cm7 with tiamat)

Thanks everybody! ....Viperboy thanks for the info unfortunately I still have lots of questions haha. And yes I already been through all the viper undervoltings, 25 through INSANE! A question I have is with those vipervoltings, I assume they'll show different results depending on which kernel and rom i'm running correct? Plus im pretty much sticking with MIUI....I usually use the 25 vipervolting. Now I'm on tiamat v4.0.3. Are you saying sense I'm using tiamat its already set to smartass, so it'll be unnecessary to use the setcpu app? Also I like savZen to what's the default governor on that? Final question, turning the data off when the screen goes off using ultimatejuice unnecessary if I'm running tiamat? Sorry for the bombarding of questions thanks again

Yes, most of the scripts lower by a certain range. So it all depends on the kernel you are running. Some of my scripts (Extreme, Insane, v2 scripts) specify all the voltages so no matter what kernel you're running, it sets the voltages to exact values. If you can go lower than -25 and you're stable, do it!
I find SetCPU unnecessary. I only have it installed because I use it for testing my mods and things, but I that's the only reason. But smartass is good enough for me, no other governors give me as good batter life. Defauly governor on SZ is their own governor (SavagedZen) it's based on interactive, I believe. There is more info on their site.
Tiamat (or any kernel for that matter) don't turn off 3G when the screen is off. You would need an app to do that.

That, I totally agree with, but for he average user, few know how to set it correctly and they end up with a placebo effect, or more problems.

I couldn't agree more. Setting up a basic screen off profile with a conservative setting is useful, otherwise it actually gets in the way of already built in kernel benefits, actually undoing them in many cases. I stopped using setcpu a while ago and my battery life has not suffered at all.

The daemon is already part of the biild props so just go into the app oc beater and set your oc the hit set perm..if I can remember correctly it won't let you set voltages. If you use a diiferent rom yoj do have to flash the daemon script seperate but with the new beastmod melvin already put it in

Can I overclock with stock ROM?

I'm quite happy with the stock ROM. Is it possible to overclock it? Do I just need to install a overclockable kernel? Will I lose any functionality due to bugs/etc? What's the most reliable kernel for O/C?
Thanks,
Nick
It is possible to OC it only via a custom kernel.............so i recommend that you try the Dust kernel by einstein.frat
Yea he's right. what you need is only being rooted and recovery for flashing kernel..and of course a program which controls your cpu such as setcpu..
i recommend you kernel that cm7 used with last update. it supports 864mhz even and with no stuck( and battery drain )if you search for it on xda i am sure you will find..

In any way......DO NOT use the CM7 kernel...........an AOSP kernel is a bit different from the Stock(sense) one.................................it won't work
Thanks all. It looks like I'll give the dust kernel a try.
Are there preset CPU MHz settings for overclocking or is any integer value allowable? Most of the overclocking threads talk about 768Mhz, 806Mhz. My guess it's probably constrained by some clock multiplier factor.
oww i am happy to learn that
Plzzz reply which wills sbe the best overclock kernel for stock miui 12

[Q] Custom Kernel, Any Advantages?

I'm not really looking for anything in particular, I just like modding and improving my Nexus 7. Are there any true advantages to a custom kernel that will increase performance and productivity? I know there's kernels which allow overclocking, I'm not sure if it's worth it when in comparison with battery life. The Nexus 7 is already speedy enough, but is there a benefit to overclocking to maybe 1.7GHz or 1.8GHz CPU?

if you're on 4.3, I can highly recommend franco.kernel. Great battery life, and allows overclocking.
Benefits are overclocking aren't really that great, especially if you can run everything fine. However, it does come in handy if you're playing graphics-intensive games and there is a bit of stutter.

Saw something about this, thought it was kind of cool.
I'm currently running 4.4.2, came across Gangstar Vegas, and it's an amazing game, it just stutters a bit. What would be a good kernel, and clock speed for running the game more smoothly? I don't care about battery life much because I'll just change the clock speed when I'm dome playing.
I'd clock it to 2.0GHz, but I don't want yo overheat the device. Suggestions?

There's also an app in the Store which does the same thing but a) forgot the name (if I remember I will update this post) and b) it's not as low-level as this kernel and so I would assume it will use the battery even more than this. This ain't "free" as well, for the record
I think enabling volume button wake is also useful, as the volume rocker is much easier to find than the smaller power button. Not sure which kernel does that though.
