OC/UV Guide - Fascinate Q&A, Help & Troubleshooting

Hey fellow newbies,
I'm looking for a guide to easily know about the whole overclocking / undervolting stuff.
I'm running CM7 with Glitch's Kernel, and I wanna do more...any links would be awesome.

Me too. I don't get how you know which voltages are not stable when it crashes

Its a rather primitive method but I set my desired oc settings and apply for now only, lets say 1200mhz to start since samsung put code for that setting in the newest release its pretty safe to say most phones will oc to this speed.
At this point I will run quadrant, then turn my camera/video on , make a test call and a few other things to put the phone under a good load and see if it freezes...if not I will increase oc and repeat the steps until it freezes...on cm7 mine will oc to 1500 but freezes at 1600. I then reboot and reset to my previously highest oc, then I try different schedulers and governors and run quadrant till I get the best score. (on demand with deadline seems to be the best for my phone) I then will go and try uv the first unstable oc and try uv'ing it to see if I can get a higher oc to run stable, if and when I gain any higher oc, I then try uv'ing my lowest steps 100, and 200 to gain some battery...this time though allowing the phone to go to deep sleep seeing if it will then wake back up...once i uv as much as possible and its stable I will apply for now...run it for a full day and will apply on boot if I run the whole day with out problems...this is just how I do it...hope it helps!

[Q] Over Clocking Kernels

Samsung Fascinate CDMA
Rooted MIUI 1.9.16
Did a brief search here looking to understand how to operate overclocking kernals, but find it/me relatively limited.
I have installed and ran Glitch v11 and v12, played around with HL to LL, and made adjustments to undervoltage utilizing Pimp My CPU and Voltage Control. I have also ran Tweak (though not really a kernal).
My question is this,
am I overclocking when I reduce voltage on Mhz's above 1,000?
If not, could someone point me to, or explain how to achieve overclocking on our phones, and
which kernel and governor do you prefer for overclocking?
As an ammended note, I've installed Tegrak Overclock, but am still looking for a user guide...
Thank you for your time.
If you're the running the glitch kernel...use voltage control, not tegrak overclock...over clocking is when you turn the CPU speed above its normal speed..anything over 1GHz.
under volting is when you turn down the voltage frequency to achieve better battery life...
Any one clock speed may perform more or less stable with different under volting unfortunately all of our phones will vary in performance so one setting that works for one may not be the best for another so experimentation is really the best option...this applies for schedulers and governors as well.
I personally overclock as high as I can until it freezes or crashes..then I go 1 setting down...I then try undervolting different steps observing the stability of my phone...when I find what I like,I run it for a few days, then if its still nice and stable I will apply on boot.
The different leakage values are affected by the hardware quality of the chips in our phones which also vary..I start with high and see how high I can overclock..note the setting, then try medium..see how high I can overclock and so on...just as a reference..high leakage creates the most heat and is the least efficient, but works for most phones, while low leakage is the most efficient and generates the least heat and will work with not as many phones

Efan450,
Thanks.
How do you over-clock using Glitch and Voltage Control? I see that Voltage Control goes up to 1,300Mhz, but it's at 0 above 1,000Mhz and can be dropped down to -200mV. Is overclocking just the process of decreasing that voltage on Mhz's above 1,000Mhz's

come on man.. Clock speed (mhz) and undervolting are 2 completely different things.. Forget the voltage.. No changing the voltage is NOT overclocking.. You overclock by changing your maximum clock above 1000mhz which is stock for this phone.. Try long pressing 1200mhz and selecting set as max.. Now your overclocked to 1200mhz..
Sent from the fascinate that holds the record benchmark on antutu
No decreasing the voltage is simply undervolting whether it's over 1000 or under. The idea behind undervolting is increasing battery life, but you can't necessarily go and set each level to the maximum undervolt (200) you half to see what works. Increasing the processor speed is overclocking, stock speed is 1000 so anything over that is over clocked. As far as how far as how far you can over clock depends mostly on 2 things, 1. the kernel your using, ( for example if it shows 1300 in the list that means thats all that specific kernel supports) 2. It varys greatly between phones. For example with glitch you can overclock to 1700 but very few phones can run that high for longer than a few minutes!
Hope that helps.
Sent from my SCH-I500 using xda premium
Yes.. And the fact you say your running glitch and your max oc is only 1300 my guess is you broke your kernel with tegrak overclocks module.. Delete tegrak and stop downloading overclock apps. or any other root app unless you know fully the consequences first.. If after deleting tegrak, and rebooting, if your voltage control don't show a maximum clock of 1700 mhz, then you will need to reflash your glitch kernel

Neh4pres,
Yeah, I kind of feel like a heel. For some reason, I had a brain fart when looking in the 'General' section of Voltage Control. I see now how to overclock.
Regarding ost #6:
When I flashed MIUI 1.9.16, I did not install any kernel; so it was kind of a half truth in that while running 1.9.9 I did have Glitch installd. Nevertheless, I still have Voltage Control installed.
mkropf,
I see that now, and thought as such earlier, but needed some clarification.
Having so many issues with Glitch and 1.9.9, I'm hesitant to install Glitch, but interested to see if it runs better on the newer MIUI...
Thank you two for answering my newbie questions.

Re-installed Glitch v12 ML last night and have it overclocked @ 1,200 with no under-voltage...yet. Want to see any adverse effects.
I started at 1,300 and it locked up then rebooted within 5 minutes.
A concern I have is that now my phone will not Auto Rotate to Landscape even though I have Auto-Rotate 'on' in Settings.
I've scoured Sixstrings Glitch thread to no avail. Though it's not needed anymore, I also flashed the cleaning script just to see if it would make a difference.
Is there a work around or fix for this?
Make sure you're on the latest 9/15 version of the kernel. Anything before that will kill all of your phone's sensors.

Yeah, locking and rebooting was while using the older version of Glitch v12. With the 9/15 dated Glitch I'm at 1300 now with the following settings:

1300 -25
1200 -25
1000 -50
800 -50
400 -75

1.2GHz is the best I say if you want good battery with a higher frequency. 1.4GHz is the best for anyone who uses their phone alot. Samsung did add 1.2GHz overclock in their source.

Back to running MIUI without Glitch.
Things that make you go, Hmmm?
For some reason, every time I accessed the keyboard for Google+, it hung, then froze, and 3 of the four times rebooted. The fourth time I needed to remove the battery to reboot. So I re-flashed MIUI 1.9.16 (effectively removing Glitch) and have 0 problems.
Bummer, I like Glitch too.

You wouldn't want to use my voltages, I put everything way lower than anybody else does or recommends and am just lucky that it is stable for me but it causes the sleep of death for anyone else.
For comparison, just run JT's kernel for a bit and then flash glitch and try it... once you play with OC/UV and voodoo color you won't be able to go back. (you'll be able to but you'd have to be insane.)

Undervolting and profiles. And xda not pushing notifications

Undervolting and profiles.
I have tried a crap ton of different undervolting setting, but none work
Also the profiles in set cpu don't seem to work for me. I have a few of them set and it always sits on the top one I need some guidence with both please!
Another thing my xda premium app isn't pushing my notafications yes its set
Sent from my MB860 using xda premium
Undervolting is a delicate process. It takes time to find the max undervolt that is stable. With that being said, try undervolting everything by the lowest amount which is -25mv. Check to see if that is stable. If so proceed to go further. Remember lower freq will typically undervolt farther than higher frequencies.
As far as profiles go your probably not using the priority values right. The higher priority is what determines which profile setcpu uses. So for instance if you want a safeguard against overheating, you could set the profile for when the cpu goes above 55C to throttle the processor way down. If you set this profile to 100(max) it will overide all other profiles at 98, 99, 75, 50...etc. Also this may be obvious to some but be sure to tick(enable) the profiles button. If thats not ticked then it doesnt matter how many profiles you have set up. It simply wont use them.

Sent from my MB860 using xda premium
Glad your getting some results. If it restarts even once it means at least one of your undervolted freq isn't stable. With your settings I would wager its in the uper freq considering your undervolt in the lower freq isn't too extreme. You might try decreasing the undervolt for your upper freq to -50 -50 -50 starting at the top. Might help to stabilize bc higher freq just require more voltage. If that proves to be stable continue trying to reduce the lower freq as much as possible. Mainly bc if you set your profiles right(screen off is the most important really) your phone will spend the majority of its time on the 200mhz freq. Thus the more undervolt on that freq should theoretically give the most benefit from undervolting. This is just all from personal experience. I'm no guru. Just spent way too much time adjusting voltages on phones . And of course having the upper freq undervolted as much as possible cant hurt either.

First off, regarding SetCpu and over / undercloking, dev has said it'll only underclock/overclock ONE core at a time. It's a bug and he's working on it from what I understand. If both cores are needed to be in use at the same time, no over / underclocking will be applied. Secondly, profiles work as they should in SetCpu, so that's a problem on your end. Third, the undervolting can't be more than 100mv differnce between jumps. See screen shot.

Yea Im skeptical about not setcpu not having support for dual cores... Did some searching on the net and couldnt find anything to support that. As far as not the tegra 2 not being able to do over 100mv jumps. That's not true. My lowest frequency is 600mv (-150) and my next frequency is at 750mv. That's a 150mv difference right there... And I'm completely stable. Its entirely dependent on your processor. They are all different and respond differently to undervolting. You just have to find what works for you. Generally though the lesser the jumps in voltage will give you more stability.
a good kernal helps too im useing faux123 v2.0 0C1.3 its undervolts quite well

SetCPU settings for Motorola Photon.

Anyone have a ultimate setting for saving battery life in SETCPU for the Motorola Photon?
Bump.. Just bought it myself will read more into it... But if someone has a quick down and dirty on settings for the photon would be appreciated... I did do some initial settings but felt the screen was getting too hot so I aborted the settings I applied.
I stopped using setcpu back when i had an HTC hero (2009). You really don't need it imo lol. Wanna save battery, use an undervolt kernel or turn off mobile data when you're not using it. You could also turn off auto background data sync.
Will look into it, just seemed that the percentage based rules looked attractive inthe program.. Always nice to be able to apply less than rules, greater than etc..
And if you're drinkin' well, you know
That you're my friend and I say
I think I'll have myself a beer
Don't think an app can control our cpu. I've tried setting frequencies only to have them ignored, pretty sure some programs will have the under volt ignored.

Its all based on the personal preference man. If you feel the need to use it go ahead. Myself, I don't think its necessary. I mean it's good for setting profiles in different situations (screen on/off,charging etc). Most of the time the kernels baked in settings are good enough but some people combine a custom kernel with setcpu for maximum control over CPU. Setcpu is absolutely pointless unless you're running a custom kernel. Plus if you use cyanogen roms it will allow you to set CPU values within the rom. Again, these are just my thoughts on it man.
Well I'm in the process of trying to get CM9 working, so I guess I wouldn't need it.
Thanks for the clarification.
Can I ask, how did you UV your cpu ? is it somewhere within the setcpu, or it comes from the kernel ? I really don't understand about ocing/uving an android phone, thx.

Custom kernels will allow you to over clock or undervolt. Set CPU just allows you to set clock speed upon boot along with custom profiles. If you install a kernel that allows undervolting it should have the custom values baked in. Again, use set CPU if you please. Joker has a set of custom kernels both uv/oc. I'm using his 1.3 oc kernel for CM7 at the moment but I'm only clocked at 1.2 just testing out. So far its amazing.

Doesn't voltage control also work? When I was using my Epic4g, i preferred voltage control over setcpu since it does both: OC and UV.
However, I'd agree with kennypow3rs that i dont think any of it is necesary with the Photon. It's quite fast already and the battery life is amazing. I hacked my Epic 4g like crazy, through 10 ROMs, OC/UV, Eclair through GB, and I have to say, it was a waste of my time. I am now extremely happy to have the Photon, stock and rooted.

I prefer to use this instead of the ones built in to cm7/9, personal preference i guess.
But the only real reason i use it is for the profiles feature. Which i set my phone to screen off to max at 216mhz(wish i could auto disable while using Pandora), then to any time below 100% battery to max 750mhz (with jokers kernel that disables the 2nd core) and then finely to run full speed when its plugged in.

Funny, I have been using SetCPU until Kennypow3rs said something. Although it worked, I have ROM Toolbox Pro. I figured out yesterday, It does all that performance crap and more. Matter fact, I got 15 hours out of my battery (Granted, 7 of those hours I was sleep!)

Changing Voltage

Are there any benefits for doing so and if so, what are the best sets for it???
Sent from my MB860 using xda premium
yes battery life can be improved significant also with the overclocked kernal you need higher voltages to remain stable.
Just to make sure you know you need to have a custom kernel flashed such as faux's kernel to do either of these things.
As for values it really is a by phone thing some people will be able to drop voltages quite a buy while other can't drop at all typically though at lower clock speed voltage can be drop much more on my phone at 1000mhz it has a 50mV drop but at 216 its a 275mV drop

Okay, I understand you. At this moment I have the 1.3 kernel from faux. I know some people said that certain voltages can crash your phone, so I wanted to make sure I had help before I messed something up.
*EDIT*
I have it set to 1.1 mhz

Use SetCPU. A good way to undervolt is to decrease all clock speeds by 25mV to start. Play around with your phone and games to see if anything freezes up. Then keep lowering 25mV at a time until you start seeing instability, then put it back up 25mV to where it is stable and you should be pretty good.

Quick tip: Before you start messing with voltage settings go to SetCPU's main screen and press Menu>Safe Mode Instructions>Extract Zip.
I hardly ever see this mentioned, but if for any reason you select "Set at Boot" when testing out settings and get stuck in a bootloop, flashing the zip that is extracted will put you in "Safe Mode" and none of your settings will be applied, allowing you to correct the unstable ones.
Thank you all for your help. I have the voltage clocked at 1125mv from 1200mv (1200mhz) mv and 500mv from 750mv (216mhz). Everything seems to be running smoothly, but haven't been able to run an appropriate test for battery life yet.

Attention overclocked users!

I planned to overclock my phone by flashing a custom kernel, my main target is rage kernel it seems like everybody likes it.
But first, is it that hard to unlock a bootloader? Could someone give a simple instructions step by step how to unlock bl?
And to overclocked users out there, what is the stable MHz that you can set on boot? In my mind, 1.2ghz overclocked set on boot is enough is it stable?
Because I remember my old LG optimus one, I can go to from 600mhz to 800mhz and its stable to set on boot.
What about mini pro? What is the stable frequency have you set on boot?
The most important is, to the overclocked users, do you notice any improve speed in games or on any part of the phone? If it still feels the same, I don't see any point of flashing a custom kernel.
Thanks

nice.. thread title made like this is some kind of important notice or such
Bootloader unlocking is in my tutorial. Whether easy or not, depends on the person, we cannot say how hard will it be for you.
Isn't the 1 GHz CPU really slow, that you want to overclock? I use that frequency whole day: gaming, chatting, music etc - never had lag problems.

Yeah I found out that 1ghz are really slow lately especially for high quality games and that's why I want to overclock.
Thanks, will check out your tutorial later.
Btw, what is your stable frequency to be set on boot? I read others can put 1.4 GHz stable on boot
edit: just checked your tutorial and its awesome! never noticed it before
btw your #8 tutorial. "8. Enabling WiFi Dual Band and Burst Mode" can that fix my wifi problems?

I keep my CPU at 1 GHz, don't need higher as I do not have any lag problems.
I don't know about WiFi.

There is no allways stable over clock. Every device has its own limits. Some Max out @ 1100 MHz stable and some could get 1400 MHz. Stock clocks are allways stable. Anything else is trial and error.

You can try 1.2gh or 1.1ghz with 1225mv voltage setting coupled with SIO or deadline I/O setting. My current is 1ghz stock frequency with noop I/O. Smooth gaming and browsing on shadowgun, samurai vengence, temple run.
Downside if you oc your phone; the battery drain will be faster than the usual rate.
