Hello everyone, I just had one quick question (I'm also very new to Android in general so I don't want to do anything to make my phone un-useable). Does Setcpu work with samsung fascinate root and clockwork mod? I heard some people say theres a seperate application to underclock and overclock the fascinate, but then again i do not think they knew what they were talking about. Is there a better program than setcpu?
Sorry if this has already been posted. I know its been posted in other forums for different phones, but didn't find one for the fascinate.

setcpu is the only and the best overclocking app. If u want to be able to overclock ur phone us have to flash jt1134s 1.2ghz voodoo kernel then use can use setcpu to overclock to 1.2ghz!
sent from my fascinate rooted and ocl'd to 1.2ghz with voodoo

SetCPU is the most popular one. You'll need root to even use SetCPU. And you'll need CWM to flash the OC Kernels. If you dont OC SetCPU is pointless
On that note.
SetCPU must be ran on conservative and with no profiles and no load on boot.
If you do reboot your phone, mine reverts back to 800, so I need to manually change it to 1200.
Do u have to set both min & Max to 1200???
no just the max

Not pointless. You can always underclock to spare your battery life

Yes, of course you are right. Actually the other day I forgot to slide sliders up from 800 to 1200 and I was getting really good battery life for like 2 hours my % only dropped 1% and I was like wow.
Im just pleased as punch that there are OC/UV kernels out, its the best of both worlds.
Actually my battery life is above average it seems; either that or my usage is below average so Im not draining it as much. I'd gladly mildly overvolt to something like 1350mV if it meant I'd be rock solid stable at say 1.4Ghz
BTW, jt I heard you might be getting out the kernel speed chase after these 1.2Ghz's? Just don't feel like chasing 1.3 or 1.4?
I am running Dirrk's D012 LV 1200 Kernel with SetCPU
Luckily, the LV runs EXTREMELY smooth on my phone..
So smooth, that for the past day now I have been able to run with "set on boot" and constant restarts on my phone..and with Profiles for Screen Off, Temp (probably wont get there), and Charging. I can say that I have had no problems with my profiles and set on boot. Then again, I don't want to contribute to hurting anyone's phone
Just thought I'd let everyone know how my phone (and potentially others) can seem to handle profiles and set on boot.

No problems with set on boot here either. I keep it on.
so how do i use setcpu/what are the steps i need to take?

Install it, tell it to auto detect, set the max where you want, leave the min at 100, and then leave it alone.

I was hoping to get some help. I have installed jt's 1200 voodoo kernal, and I can't seem to get Setcpu to clock at 1200. It still says that the max is 800, however, on the slide it is only giving me the option to goto 528. Bellow are my facts, any help would be great!
Facts:
1. flashed jt's overclocked voodoo use clockwork, but did it through "install ROM from sd card". I am not sure if this is correct, but it seems to be running voodoo.
2. I have no idea how I need to have Setcpu set up.
I feel like I am blindfolded and I am trying to wack at a pinata.
thanks.
Edit: never mind...even a blind folded monkey hits the pinata every now and then
I dont know if anyone is having this problem but on pretty much any rom/bootloader combination my tablet will only run at stock speeds and if the rom is overclocked on first boot my tablet just wont boot at all, I know some processors are slower than others but is it really likely that mine maxes at 1 GHZ? If i use setcpu to OC when a rom is running smoothly it will run fine for about 1-2 minutes or until i needs a lot of cpu then it just freezes. Any ideas to fix this, or just help understanding what is going on would be appreciated. My CDMA hero overclocks just fine and crashes instantly if i go too far unlike the tablet.
I know that this will sound like a stupid question, but are you certain that you've loaded a kernel that allows for overclocking?
what rom/kernel combinations have you tried?
Calkulin Clemsyn combo is what I'm using, and the overclocking appears to be working fine with Clemsyn's kernel.
Try CPU master from market. The free version works fine. Should do what your looking for. I have the paid version of Set CPU and it has never worked on gtab for me.

Well, I'm surprised no one before me has tried to make this clear yet. Pershoot's kernels are written for setcpu. Clemsyn's kernels are written for cpu master. Make sure you use the right cpu app.

Im installing that now, hopefully it works, it should, ive only tried setcpu to this point.
EDIT: nope, it still locks up, maybe my tablet just wont go that fast?

Not all chips can be overclocked to the extreme. A few can't handle it at all. Try some small increases at first to see if your chip can handle it.
I've also had some luck with finicky chips using PimpMyCPU with Celmsyn's kernel since it allows you to set specific speed and voltage combinations (Not sure if CPU Master allows that... never used it). So you might give that a try.

me to Calkulin Clemsyn combo is what I'm using, and the overclocking appears to be working fine with Clemsyn's kernel. from 1k to 1.5 k and works great and I am using CPU master also
Are you clearing davlik cash between each kernel switch?

Only his latest kernels have worked with it. Setcpu didn't get on there end of the process until late may-ish, I believe, when they finally supported tegra2. Still CPU master works with pershoots kernels too. Its basically a re-branded copy of setcpu anyway.
No matter what combo of app/kernel/rom it wont go to 1200 and not lock so im just thinking its one of the slower tegras, which sucks but oh well

That's just it. It's not written anywhere before I wrote it. It's like masturbation. It's not really written anywhere for a 12 year old to learn about. Eventually, they all figure it out on their own... or they become the 40 yr old virgin.
Not positive it will work but for desktops, back when I overclocked religiously, instability could be helped by raising voltages. But it might increase heat which also leads to more instability. Lucky for us, tegra 2 is low voltage.
Just flashed faux's newest kernel, and it has undervolting.
I'm wondering if anyone has experience with this or has a guide for it.
I just want to maximize its potential.

there is no specific guide. Unfortunately every CPU is different so the values you can use to undervolt will be different. Check out Faux's Thread Around page 50. There should be some info there.
Read Faux's kernel thread. There are several settings that people have posted and some info on how they tested their phone.

Just have to play around with it. Usually start off with the lower frequencies and see if stable. Then continue up.
Good rule of thumbs are the higher freq, the less you should undervolt.
Another important thing is uncheck Set on Boot. Last thing you want is for it to be unstable and you're stuck in a reboot loop cause it keeps setting itself.
I've been interested in trying to undervolt now with all the kernel talk. I tried once, but never got it to work, and now, I have the same problem. No matter what kernel I use, the voltage options are not available on multiple different cpu control apps. I tried incredicontrol, setCPU, Voltage control, antutu (only one at a time, uninstalled after nothing worked). This is with both sebastians and DSB's kernels, and on ViperROM, Business Sense4, and Neos crazy ((((x)))) rom. Nothing. I flashed the Global RUU before all this, as I was on the .10 leak, and since I was messing around so much, felt like a clean start on a fresh RUU install was a decent idea. I can control the CPU speeds just fine, no problems with that, and also did check that the kernels did in fact flash. Order of flashing I tried: Rom, boot up once, back to recovery, flash cache and dalvick, flash kernel, reboot. Also tried not wiping caches', and also flashing everything at the same time, no luck, still no voltage controls.
Also, not as important, but I would love to get it working, Sebastians kernel says it has OTG working, but I can't seem to get that to work either. If it matters, I'm trying to get a cannon camera to work with Chainfire's Remote Release app. The only thing I'm unsure about this, is if I need to add power from a USB hub, like Sebastian talks about needing for a usb stick on the Sensation.
Anywho, thanks if anyone can help.

Haven't tried it myself yet, only tip I've seen is make sure you're selecting CPU1 first before setting voltages and they'll stick.

I never understand why it's cpu1 since cpu0 should be the one that's adjusted since it's the one mainly used. pretty dumb to make the 2nd CPU as cpu0.
It really shouldn't matter what cpu core is set first.
The most probable reason you are unable to undervolt is because there isn't a kernel that supports it yet as far as i know.
correct me if i am wrong.

Don't know the reasoning for it, just what I've seen in dsb's kernel thread.
So, if I get what you guys are throwing down.... I should see sliders for both cores? I do not, I get one slider.... deeerrp, actually, I just tried the app "System Tweaks". It is telling me cpu1 is offline, but that app is actually letting me undervolt. So now the question is... how do I get cpu 1 up and running?

Ok, I must just need to read up on this further. I forced both cores online, and at least now I know they both come on. I'll poke around for recommended settings.
Anyone got any info on usb OTG? That would be super swell if I could get that up and running.

I've found questions about apps and how to do this or that to a kernel with an app. Here's my two cents:
Make a simple script. They're not hard to slap together and there's plenty of stuff on XDA and the internet to help you along. You can set your governor, governor parameters, voltages, clock speeds, all that jazz and a WHOLE lot more than most of these apps will do. Plus, you don't have some resource sucking app running eating away at the performance benefits a custom kernel brings.
I am coming from the Droid X where we were not able to change the Kernal. So all this Kernal stuff is kind of new to me. I finally rooted yesterday and am running viper with LK DNA .94... So what is the best app to use for tuning the Kernal? Is this necessary? Is their a thread where I can read up on this?
Thanks for your help
Either use trickster mod or system tuner.
You can lower the voltage(save battery), up the clock speed and change the governer(change performance/battery life), etc.

There are a few to choose from, but system tuner works well. Keep in mind though that it is completely optional to overclock/undervolt, and the kernels work well as is. Overclocking too high can damage the phone (I recommend not going over the stock 1.5GHz unless you know what your doing), and undervolting can make the phone crash frequently. If your read up on a few guides it can be done completely safely, but you may find you prefer to leave the kernel's default settings as they are known to be safe and stable and are already optimized over the stock kernel.
