Cpu speeds after root

Wanted to start a thread so we can start tracking successful overclocks and underclocks.

tried setcpu, gave it su permissions, but dont have a setcpu.txt file for applicable speeds. tried to put droid speeds on it, but it somereason refuses to set?

did you autodetect?

after autodetect it gives a max of 600mhz ...
isn't that stock?

Pull it from Wes's github. He has it up to 998 from the looks of it

I thought there was a big hullaballoo over the G1 and overclocking and it was discovered that unless there's a kernel-level modification, the overclock widget doesn't actually overclock beyond the max the kernel says it can go(like, it will SAY it's OC'd but will still be running at stock)? Maybe the same kind of hack can be used from the G1 since it's still an ARM11 processor? Sorry about my non-specific rambling, I only have a very rudimentary understanding of this >.>
Perhaps a couple threads on the matter will help. These are threads about the actual kernel modification/hack that allows the OC'ing on the G1:
http://forum.xda-developers.com/showthread.php?t=666850
http://forum.xda-developers.com/showthread.php?t=679033
FWIW, there's no OC'ing on the Legend yet, and it uses the same processor as our beloved MTS. I'd love to be able to get more out of this device though, hope we see it soon
EDIT: It's also worth mentioning that in the beginning of the G1's life when people were "overclocking" it to 528mhz, it wasn't actually overclocking. It was only that the processor was UNDERclocked by the stock software to 300-something mhz and we were overriding it back up to the intended max speed of the processor, 528mhz. Only recently have people truly started OC'ing it beyond that with these kernel hacks. On the MTS, I appears that it STARTS at 600mhz, which is already the max intended speed of the processor. So if we want more we'll need these kernel hacks. I'm hoping we'll be able to get at least 800mhz and still be stable <3

it took the g1 a good deal of time to have one too right?

If some good developers come soon it should be possible to overclock the kernal maybe try porting from the hero that has many overclocked kernals thanks to behnaam

Hope you dont mind Wes
This is what i was speaking of. It looks like he is already working on it. i'm not a dev but i can tell that this rom in the making is going to come with some yummies.

thanks for the heads up man, I'm no dev either but that sounds awesome. I'm hoping to overclock this bad boy and get him just flying (not that he isn't already). I was searching for the power profile already on the Slide to see if it's possible to just rewrite the current file, but I can't seem to find exactly what I'm lookin for. Guess I'll just wait for a ROM update

The real trick will be to do what we did to the nexus . overclock undervolt

Stock Android 2.2 FROYO (Samsung Tablet)

As many of us know, Samsung Created a Galaxy S family brand (captivate,vibrant,epic,fascinate) along with a tablet.
The tablet boast the same features/specs as most of the Galaxy S Line
Froyo
480x800 resolution (Super AMOLED)
Camera resolutions -- 2048x1536 rear, 240x320 front front facing camera
S5PC110 Hummingbird at 1.0 Ghz (same CPU as the Galaxy S series phones)
Flashplayer
GPS, WiFi, Bluetooth
Swype
JavaScript 1.5 support
SyncML (Synchronization Markup Language) support

The tablet isn't out yet, but the FIRMWARE IS!
So here's Froyo for the tab http://www.multiupload.com/TZ88IED0TN
rar password is: samsung-firmwares.com
Lets see what you devs can dig out, for the improvement of our phones

GREAT FIND!!!! Can't wait to see what you guys can make of it. If most of the hardware is close enough to the same as far as the camera and what not we may even be able to port this, also I thought the tablet was supposed to have GSM radios in it as well. That would be fun lol. Good find though.

by the time this rom gets repackaged for the captivate, the official froyo rom will be released.

dont lose the faith buddy

two questions:
1) Has anyone tried to flash this yet just to see what it's like?
2) If someone has flashed it, have they been able to successfully revert to a stock captivate rom?
I'd love to be the guinea pig, but I wanna make sure this isn't a one-way deal
EDIT: Tried it, boots to a screen that looks like someone is trying to get a signal on an old tv with an antenna(grey and black lines). I didn't check if it went any further, just pulled the battery and flashed back to jh3

The tab has a 600x1024 resolution. Samsung firmwares web is wrong about this. This can be deduced from the dump of the fw. Apps are showing a 600x1024 layout, the shutdown animation pics all have a size of 600x1024 etc.

odd, all of the post install stuff looks for I9000 as well as the tablet... maybe this will flash to an I9000?

I agree, we should find an I9000 guinea pig, because the Galaxy S Tab is a Giant INT Galaxy S, as an Ipad is a giant itouch.

Already tried it on my GT-I9000, and i'm getting the same results as the others in this thread... aka it doesn't get post boot screen

I would be very surprised if just flashing this on the phones would work - the hardware must have enough differences that we'd need the get our drivers into the rom. If this was a source dump, then we'd be talking. It does bode well for Froyo on the phones if they have it working on the tablet already though.

Chit. I use my captivate like a tablet. I don't use it as a phone. I use my everyday phone the N1. I would love to have this ported to my captivate though. Then it will be my real samsung mini-tablet. LOL. Stupid me... I can wish though. I also wish someone could ported to our phones.

The resolution is 480x800 because Froyo doesn't support any higher.

I'll try to flash this and see what I can do. Not sure I'll be able to get too far, but I can at least try, right?

We are just about in the same boat lol. Although I do put my sim card in my Captivate at night and use it as a phone, I've never taken it out with me for a full day (my Nexus One has that duty for now).
Hopefully soon I will be able to get my Captivate set up the way I want it, then it can be my daily driver.

Yeah. Got the captivate and returned at first. I kind of wanted the bell vibrant. But thought about it little more and rebought the captivate. I waiting for cm6 on this thing. It will be so nice. I really like the galaxy s series. However, my trustee n1 will be with me for a while. Not until cm6 is available for the captivate.

maybe samsung made a custom build? i honestly have no idea as although the firmware they released points to 1024x600 you are right about froyo supporting only 800x480. weird

This may just be nonsense, but is there a .tar file with a stock i9000 kernel for one of the froyo builds? If so, might this work if someone flashed that .tar after this one? Just a thought.....
EDIT: Just for kicks, I flashed the stock captivate kernel after flashing the 2.2 tab rom, and I was able to get to the recovery menu where it failed to install/check for some package and wasn't able to complete the installation. Trying to boot afterwards resulted in my captivate being stuck at the at&t logo.....
EDIT2: Since I was doing something useless anyway, I flashed the xxjp3 froyo rom for the galaxy s,then the captivate kernel, and it goes into an infinite bootloop. Again, this was just for kicks. Flashed back to jh3 with no problems.

Ok... Well.... I managed to get into Recovery from flashing a stock zImage.tar.
What can I do from here? It won't get past the ATT logo otherwise...

You don't. You go back to your back up. Its a no go.

[INFO]A New Kind of Lag Fix

A fine fellow named supercurio over on the I9000 boards has found a way to do a FULL FILE SYSTEM REPLACEMENT. It just started beta testing and the results are VERY positive. He's indicated that he is interested in porting it to the other variants, so I wanted to make everyone aware.
This whole thing started in a bounty thread to fix the I/O issues on the SGS, so I was hoping maybe the Captivate community could go over there and throw some cash into the pot to sweeten the deal a bit and show our support for what he's doing- this will also hopefully increase the likelihood of a port =P
http://forum.xda-developers.com/showthread.php?t=748880
supercurio joins the discussion at the bottom of page 6
Of course if you haven't already, and are using one of the current lagfixes you might consider throwing a few bucks Tayutama and RyanZAs way as they've been absolutely instrumental in the process of getting this lag fix movement off the ground in the first place!
Tayutama's Donate Link
RyanZA's Donate Link
And lastly, a little something to get your mouths watering:
http://www.youtube.com/watch?v=Tc_PbQe1WVk
Launching and closing some games:
http://www.youtube.com/watch?v=cYcRq6ln0fc

This is a huge step in the right direction. In for this !

I'll be following this, as of course, ryan, tayutama zilch and I have been just waiting for a way to replace the damned rfs.

Wow that looks good, can't wait to help test out the beta. I'll be donating as it progresses along. Any word on when the beta will release?

Well right now the I9000 crowd is testing, he had a really limited beta release yesterday. I told him I've got a spare captivate for a couple days if he wants to run any bizarre experiments without fear of bricking, hopefully he'll take me up on it

I hope so, i'm running the I-9k JM1 rom on my captivate right now without a lag fix just cause and it works great! can't imagine the difference this will make.

This sounds like the lag fix I've been waiting for. Once it is out of private beta, and compiled for the Captivate, we need it added to SRE. Can someone get Samsung to add this to stock FroYo and ditch RFS for good.

[SOURCE] Supercurio's EXT4-based "Voodoo"Lag Fix
Picked this from the vibrant forums
Hey everyone,
Seems Supercurio has finally got a beta of his true fix for the lag on Samsung Galaxy S phones. The github is below.
DO NOT FLASH ON A CAPTIVATE until there is a Captivate version. This is posted to developers can take a look at the source code and start implementing it for the captivate.
http://github.com/voodoo-project/lagfix
Hopefully unhelpful or someone else can integrate this fix into his OC\Stock kernels, and we can enjoy our phones without the typical "galaxy s" lag/stuttering.
HUGE thanks to supercurio for all his hard work putting this together
EDIT: lol, guess he hasnt posted the source yet. the ramdisk is available in the download section.
Enjoy! Happy coding!

DO NOT flash this to your captivate. This is based on an I9000 kernel, so all the I9000 problems come with it. Wait for one of our devs to convert it over to stock Captivate.
It does however work using I9000 firmwares- I9000 kernel glitches still apply =P

Nope, just a patched kernel and a script should do it. This is the holy grail of lagfixes, I believe.

I am planning to flash this to my JM7 ROM once i get home lets see how that goes.

I'm running it from an I9000 ROM atm, but you HAVE to keep the I9000 kernel for it to function, you can't switch back to the Captivate one, and seeing as how there's no revert for this ATM this might not be for everyone
Also Rom Manager doesn't work with this =P

Calls and data work just fine. I'm using the I9000 kernel and a JG8 modem firmware (so I get 850 and 1900 mhz bands), it should still work with the stock captivate modem files too.
Basically you have to deal with reflashing a kernel whenever you want to run an update.zip and autorotate is boned

Evo Shift Merge?

From what I know, the Shift is the Sprint Version of the HTC Merge(or the other way around). And, since there is no Merge forum I could find, I came here. Is it possible to oc the device to 1ghz? Or, is it like the G2, where 800mhz is enough? Also, does it happen to have 512 mb of ram and a ffc? If so, Im dumping my droid 2 for the merge(unlocked bootloader ftw!)
Sent from my DROID2 using XDA Premium App

you can overclock to 1.51 ghz with it rooted and it is very smooth and very fast i can say i had many applications in back ground and still managed to go on the web and it was very quick still and play games with no problem very smooth.

The shift can be oc to 1.8 my friend and the g2 can do 2.1
No ffc tho sorry

He's asking about the Merge, guys. It SHOULD be very similar to the Shift, but nobody knows for absolute certain until they can get their hands on it. For the record, the 800 Mhz processor did everything i asked of it and then some at stock speed, I only overclock it because I can

Anyone got their hands on an HTC Merge yet? Mines definitely great at 800 MHz, and there is nothing i have come across where i felt more clock speed would've been better, and that too on stock rom. This includes some of the heaviest games graphics-wise available on the market. But since its still not officially out, Im still running it on stock as I have no idea how to root it and load custom recovery. As soon as we get custom recovery on this it is a given the performance will increase a lot with custom roms.

i think you have to wait for a stable app which doesnt have a problem with exynos 5420.
but come on what do you want to do with 3.0 Ghz processor
it is very unnecessary and "if it is even possible" it would just drain your battery, it won't give you a supersonic performance.

You would need a kernel with oc support and there aren't any out yet. You will just have to wait

You could say that I am. And yes, a few kernels run the note 2 up to 1.9 and 2.0. I personally run my own compiled kernel from the devil kernel's source. With a few editions of my own
Give it time. It will come, however 3.0 is not even reasonable. If we see an OC, you're probably looking like 2.5 at the max.

I would never say 3 is possible. Also I would not see a need to oc at the moment when is already smooth. More effective would be custom rom

having played around with many Samsung phones, I've always seen them get about 30 to 40 percent higher frequencies, hence why my Droid Charge was able to be overclocked to 1.3 gigahertz, and the Galaxy Note 2 was able to get over clocked to 2 gigahertz. we will probably see 2.8 has the highest stable
