[Q] Overclock question

I am using Setcpu on my motorola droid with rooted FRG22. Why wont it let me overclock it higher than 800mhz??? I'm kinda new to doing this and wondering if I'm doing anything wrong. Thank you

[A] Overclock answer
Yes you have SetCPU and your phone is rooted. However, you're missing one more piece to the puzzle. In order for you to clock over 800Hz you have to install a kernal cooresponding to the voltage and what you want to overclock it to. I recommend you googling(haha) p3designs and choose a kernal you want to try. Instructions are on the site as to how to install. I currently have a low voltage of 125Mhz overclocked at 1Ghz. Hope that helps

Question for you Stephen, with you running 1.2Ghz on your droid, has there been any istances of freezing thus far? I was tempted to go higher, though I stuck with 1Ghz to be safe.

The right approach to overclocking is not how fast can you go, but how low can you tolerate? Most Droids are stable to 1.2 ghz. Some can go higher, some can't. I'm running the "stock" 1ghz kernel that comes with Sapphire rom. However, I have it choked back to 800mhz. This gives me 36 hours of battery life on light-moderate use, (3G off, wifi on) but also lag-free performance.

This is chevys 1.25 medium voltage, only reboots were with watching movies online.

The links for the kernals over at p3designs don't seem to be working for me. Does anyone have some overclocking kernels they could post?

I understand what you mean. I've done the trial between 800Mhz and 1Ghz. I have emulators now and I liked the performance on the 1Ghz more because of the speed, so I kept it on 1Ghz. I haven't had any battery drainage issue and all. I liked my low voltage 1Ghz kernal.

Is this the site you tried accessing the kernals? I did a test and downloaded the kernal zip fine.

That does sound impressive. I'm curious to try that out even more so now.

[Q] Benefits of OC/UV

What are the benefits of OC/UV (particularly for CM7)?
I know of improved performance due to OC, but what does UV do in regards to performance. Also, how does an OC/UV kernel compare to one without the option?

your processor doesn't need as much voltage as the stock settings--undervolting lets you save battery
personally i want to know.. do you have to UV to OC?

You can do either or both but don't have to do both. At some point UVing will cause a crash. Right before that point it can cause performance issues. See the link below for instructions on how to find an optimal UV level to maximize battery savings and performance.
http://forum.xda-developers.com/showpost.php?p=10936691&postcount=1102
OCing improves speed but can also cause stability issues. For a captivate this usually isn't a problem until you get past 1.2 ghz. After that, it depends on the kernel but I have yet to find a kernel that is completely stable past 1.2 ghz under stressful conditions. Samsung designed the processor to handle 1.2 ghz and in theory it can go up to at least 1.6.

Like everyone before me has said, OC will make your processor work more (which will eat up more battery, and send the temps a bit higher).
UV is a way to "fix" that problem by controlling the voltage used by each Mhz/Ghz range. The mini guide that QuarkGluonSoup posted is a great way to start off.
Most Captivates start have random errors past 1.2Ghz, but the highest I've seen (stable) are 1.4Ghz.

Odd as it sounds, my battery life on CM7 is close to 50% better when it is OC'ed to 1.2 ghz and UV'ed than it was on the froyo ROMs under the same conditions.

That really is odd :S I think I'll try it myself.

[Q] Overclocking ?

I have a question: why I can't overclock my SGS past 1.2 ghz. When I try to set for example 1.3 or 1.4 it freezes and I take out the battery in order to make it work again. Is there something I do wrong, is it a general problem with more SGSs? If somebody can , I really appreciate. Thanks

it is a kernel thing.
the kernel has to support those frequencies.
Sent from my GT-I9000 using XDA Premium App

I tried with tegrak overclocking with voodoo kernel (the application itself doesn't need a kernal that supports those frequencies) and with Supe Optimized Kernel (1.4 ghz) and voltage control and setcpu and is the same result:freezing.

Not every cpu is capable of stable overclocking past a certain threshold. You have probably hit the max speed your cpu can maintain.

I agree with you but then why there are other people with the same phone as me that can overclock them at 1.4 ghz?

With CM7 or miui and either bilboa or zacharius kernel you can overclock to 1300 but I haven't found a kernel that allows 1400 either, I think those that are doing it are hacking the CPU settings themselves.
My phone gets really hot at 1300 running apps like dungeon defender so 1400 might just be a bit too much

I am using Darky's 9.3 ROM but my problem is that i can't even touch 1300 mhz because my phone freezes.

Maybe a dumb question, but, do you overvolt as well as overclock? Maybe the cpu isnt getting enough juice?

+1... not sure if there is much benefit at all to undervolting.. it just seems to make it immediately less stable...
can someone shed some light?
I've seen someone test this on another forum somewhere, and the difference the undervolting makes to the battery length is negligible..

The principles of ovetclocking a PC also aplly to phones. Undervolting reduces the power available to the CPU. Undervolt a little and you'll save a little power. Undervolt.too much and the CPU won't get enough power to do basic functions hence freezing.
Every CPU has a limit to which you can over clock. You can overvolt to a point but then then the CPU reaches its limit.
From what I understand (read in another post) the hummingbird processors are not suited to overclocking. Where the arm such as that in the Motorola milestone clock really well. (You can oc a 600mhz milestone to 1ghz before you start seeing instability)
Hope this helped.

I understand the intention of undervolting as i am pretty good with PCs. Got my good old i7 overclocked constantly. But undervolting on the SGS has yet to show me any definitive advantages.

[Q] Fastest Captivate 2.3 Rom?

Which of the current 2.3 ROMs is considered the fastest/most responsive? Or which ROM would be considered the fastest based on the mods & tweaks used by the developers? I'm not to versed in the technical side of things to discern which tweaks/mods/kernels/etc give way to the most stability, speed, and response and would like the community's opinions on the matter.

Probably CM7, I just started using it and there is never any lag. I haven't even OC'd it yet. This also comes with the price of having to live off a wall charger though.
Sent from my SGH-I897 using XDA App

If you mean fastest in clock speeds, then thats a balance betwen rawr clock and how much battery life you can get out of it. Keep in mind these phones clock easily 1.2ghz-1.3ghz no issues past that you need to increase the voltage. So you can in theory get 1.6ghz-1.8ghz but you will live next to a charger. If you mean fastest on how it feels Id have to say Continuum moved awesome few months back (haven't used it in a while) Atomic Fusion if the ext4 version comes out. But there you should just test them out.
On a side not if you want to OC your phone and not have to pay for the oc app, then Id suggest you stick to I9000 ports or AOSP's like CM7 or MIUI. Native roms like Cognition 5, Atomic Fusion and Nuclear Fusion need Tegrak for OC/UV.

Which of the I9000s seem to run the fastest/smoothest? I've been looking at Dlev and Darky but how does Apex/Symply GS II/Mosaic/Sensation compare?

I actually read in the Glitch kernel thread that when overclocking, higher voltages doesn't always mean more stability. I'm OC'd at 1.5ghz right now really stable and I was UV'd at -50mv but I just dropped it to -75mv to see if its stable there. I'll keep dropping it till I have issues.
Oh yeah, and CM7's battery life has got WAY better over time, so I'm not having to worry about charging all the time either.

From my experience to maintain a stable phone i over volt the "step" that's overclocked, and then undervolt the other "steps". Im by no means a expert nor is there a full proof way to do it. Each phone kinda reacts differently on the overclocking past 1.2-1.3ghz.

Which of the I9000 roms should theoretically run faster due to the tweaks/mods used by the developers without the need to overclock?

There if no need to overclock for daily use. Only if you are playing very demanding games. And only during those games.
As for fastest rom....have a search this question gets asked a lot with always the same answer and result:
There is no best rom, all phones are different as well as tastes, what's best for me on my device may not be on yours. Flash and try a few and make you own decision...

CM7 is fastest but Display and Sound quality is not as good as stock ROM .

Before school started for me and i couldnt access a charger when i wanted to, i used MIUI at a stable 1.6 GHz ALL of the time with odemand govenor and i got like 18 hours with moderate use, on Glitch V12! And you dont need to overvolt for higher speeds i have tested it and its better to undervolt higher clocks, i get better battery and performance!

For the 10th time Each phone reacts differently to Overclocking. There is no sure way to get it OC/Uv. On my phone past 1.2ghz i need to over volt.

Lower cpu voltages.
#Note, seems screen is eating more battery than CPU. Will investigate.#
Plan for V5
More governors, possible UV compatible with Xan's Voltage Control app.
If you have suggestions, ideas, please give me them.
I do plan on more governors (maybe smartass, interactive, ect....) more io schedulers (bfq, ect...) and anything else that comes my way.
Special thanks to those who have gone before me and helped my learn what I have: gtg465x, LinuxBozo, and Entropy512 for everything that I've learned from them in the Infuse 4G forums, Excaliburinhand for encouraging me to start my own kernel, CallMeAria, Urabewe, tylerwagler and gtg465x again for what they've done here before me... and to you for choosing this kernel (I know... Video game cheezy, but it's true. )
Git is below, it is under the wagler kernel git as it was what I forked and am pushing to. I decided it's time to get started with this.
And please remember, thanks button is good as is fueling my insanity. If you look at my Infusion kernels, I do recognize my "Insanity Crew." (and if you want to be kept in obscurity, I respect that as well. )

Good job man, everyday this forum gets better.
...fighting ninjas at night. Talking about this and that.

Good to see you guys pushin' the kernel movement forward, and sharing your work.
Good deal on getting that built in overclocking going as well. I've been running the kernel for the past day. I did notice an issue, though. Maybe it's just my phone... But the 300mhz OPP, is not being utilized.
I've attached some screenshots.

I was planning to mention that, will try to fix. (100-300 bug) on battery life, what governor are you running? I've found better life on conservative or on demand.

my battery life is decent not the best try to calibrating battery will give you a decent battery life

Usually I'm in hotplug or performance... My device has no service, so it doesn't see "normal use" like most. Most of the time it just sits and sleeps.
So, what I did yesterday, really because I wanted to see if you guys squashed the random reboots I've notice in my own playing with LG's kernel source... Had a fully charged phone, flashed your kernel, ran a few benchmarks, still had over 90%, and just let it sit in hotplug. got back to checking it out maybe 12 hours later, noticed the drain, checked setcpu, and that explained it for me. My phone normally would be 80% to 90% in 300mhz... But I don't think 100mhz is able to accomplish most tasks, so it's always popping out, even when it should be idle sleeping.
One thing for me is wireless tethering.. The device needs to be able to accomplish this in the background, and 300mhz even on a DroidX is able to accomplish this. 100mhz is a no go, though.
If you find it real difficult to get 300mhz functioning with 100mhz, I'd say chop the 100mhz out for now, and give us a bump, or atleast put out a 'high voltage' 1388000 mV(TI's kernel 3.0 number) top slot version of the kernel... The overclock module still works with your kernel, BTW... So, in combination with the voltage bump, those that are real speed freaks can push toward that 1300mhz mark with stability.
P.S. No random reboots, so that gets a big thumbs up!!!

I'm going to try and keep to 5 freqs, going to see if 200 works. If not 300 will be low end. Wanting to see if 1.4 or 1.5 is possible with proper voltage. (we should reach sgs II performance benches at that level. )

I think I got an issue. Starts to lagg when typing/texting. Maybe its the governor I used. I tried with both concervative and ondemand. Also hotplig too. Conservative had the least amount of lag but still noticeable. The other 2 were way too laggy. Unusable.

I believe that's due to the 100 MHz freq. I rebuilt later night without it and while I am typing this there is no lag for me. Re-uploading V2.

Anyone flashed this can comment on battery life and any issues?

Haven't had it long enough for battery use, but it made slim doomed speedier.

Flashed it. So far no lag. Battery life kinda iffy. But it's a brand new battery. I'll clear the stats and see how battery life is then.

No issues, phone feels really fast, more batt drain though. I like it.
