[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.

Is oc risky?

Thinking if overclocking my captivate to 1.6 but will it shorten the like time significantly.

Very.

Yes it will shorten the life on your phone no way to know how much though. unless you are into it and read a fair amount about it i would not oc. The benefits just are not that significant

start at 1.2 if your scared

It will not shorten the life to the extent that it will not last the update period

Oh well how long do u think it will last. N I want it for the extra speed in games mostly.

If you want some extra speed, still to 1.2 and below and try using Pimp My CPU to drop the voltage -50mV across the board (try messing around with it more to get more drops without charge deaths and etc). By doing this, I am running mine currently at 1.2 ghz with a -100mV voltage drop, which is the same as stock 1.0 ghz voltage level.
It's overvolting that kills a processor, not overclocking. More voltage means more power for the processor to dissipate as heat and some components are not spec'd to take more voltage than stock.
I hope this helps.

I have read that you should be safe up to 1300mv(not mhz). Usually 1200 mhz will run that. After 1300mv, you risk damage. It also can cause charging issues (phone uses more battery than it is charging).
Don't get me wrong, at one point I had my phone up to 1500 mhz, just to check kernel stability. Didn't stay there. Also remember that each phone is different when it comes to this. Some phones tolerate it better than others. That is why entered no definitive guide to it, only recommendations.

You shouldn't be scared to OC. but its your phones processor because everyones is different. My captivate can only get up to. 1.5. Then it freezes up. My inspire 4g can get up to 1.9 without a problem while others can only get to 1.6 or so. So try it out

[Q] Nook color overclock.

Hello
I recently acquired a nook color and i am going to install cynogen mod 7.1 and google apps from clock work recovery method, but i want to overclcok to 1.2 or 1.3 ghz, i understand that cynogen mod has an overclock facility built in, the part i am not sure about is to reach 1.2 ghz or 1.3 ghz do i have to use dalingrin overclock kernel to achieve these speeds, or is it possible in cynogen mod 7.1 without the kernel.
Any info would be appreciated.
Regards
Mark

Dal's kernel has been included in there for a while now. If you use 7.1 stable to later nighlies you are definitely safe.

ok, thats great, thanks for the reply, appreciated.

It appears the GPU may run best at 1200, even thou the CPU can do up to 1300.

It certainly seems to be true that going past 1200 can slow down graphic intensive operations. I am guessing that's probably because the graphics processor has to run at a ratio of the CPU and going past 1200 ends up with a lower graphics frequency.
But depending on the type of applications used there can be benefit in going higher and most Nooks seem to be capable of 1350. This can be seen in two different benchmarks. Quadrant gives significantly higher scores at 1350 than 1200 whilst the graphically more intensive Nenamark is slower at 1350 then 1200.
I ended up using 1200 anyway as it feels fast and probably also helps with battery life.
Check the voltage settings as well as these can normally be lowered a bit to help again with battery life. I use the one's originally quoted by Dal and don't have any stability issues. ( 09.25 / 1.05 / 1.2 / 1.275 / 1.325)

I did a comparison of 1200 and 1350 MHz with the Sunspider JavaScript bench. 1350 is faster but frankly I have a hard time telling the difference between even stock clock and 1350 in actual practical usage.
The most obvious speed boost I've found is running 16bit color. Big difference in browser scrolling performance.

Is overclocking it fully safe?

From the standpoint that breathing in a metropolitan area is not fully safe, no it is not.
I use the stepper built-in to 7.1 stable and have never given it a second thought.

Try nook color tweaks.

I have run at 1200 / 1350 for the last 4 months and it has been stable and I have not seen any real detectable difference in battery performance or in how warm the device gets. The governor means that a lot of the time the Nook is running at lower clock speed anyway.
I don't recollect seeing any reports of damage on this forum to the Nook through over-clocking. Increasing voltages from the stock values on the other hand is probably not a good idea. There may possibly be longer term effects from overclocking but I'd guess the effect on lifetime is small enough that most people will have changed their device before it is significant.

Being that Nooks CPU is underclocked by default. It is very safe.

[Q] Overklocking and kernels

Hi!
I've struggled with my Incredible S for a long while now. Asked questions here and so on but haven't really got any answers.
Things went something like this: My mate rooted his and my IncS same time with Revolutionary. We both installed ARHD and overcloked to 1920mhz just for the lulz. Everything went just fine for a while for both of us, but then I decided to restore my apps sms etc from the stock rom with MyBackup (or what ever its called). Restore failed at some point and I needed to flash ARHD again.
Ever since my CPU hasn't been able to reach 1920mhz or anywhere close ever again. I've been flashing dozens for ROMs now and only few of them could be O/C to 1600mhz. Some freeze at 1152mhz instantly, others can be stable for few minutes and then crash.
My mate is running CM7 with enki-v0 kernel at max O/C without any problem. I tried CM7. It started to become unstable with default O/C after few days and I had to siwtch back to some Sense Rom that worked at normal O/C.
Why some kernels (forexmpl Quattro beta 6) allow me to O/C at 1.6Ghz and others freeze just at 1.1Ghz? (Affinity,Unity,Niks trinity, Quattro betas 7- Rc3)
And why my CPU can't reach the 1.9Ghz anymore? Could I **** something up and the CPU is broken now or is there something wrong with my rooting?
TL;DR Only few Roms and kernels allow O/C and with them its a pain in the ass cuz of unstability, why?
- And I'm not looking for solutions like "Flash to stock". I know how to get it stable, but then again 1Ghz stock ain't that cool.

How are you overclocking? I've never used CM7 before, but I do use SetCPU. Every time you flash a ROM you need to go into SetCPU and Device Selection and then Autodetect Speeds Recommended. Either that or you can try selecting Show Other Frequency Sets and pick your processor from there.
Basically the only thing I can think of is that your processor is not being recognised correctly.
BTW When you say "Everything went just fine for a while" how long is a 'while'? The only reason I ask is, how sure are you that running your processor smoothly at 1920mhz for that period wasn't just a fluke, and your phone (for whatever reason) cannot normally run at that speed? From what I understand, even phones of the same model can differ as to the speeds at which they can be overclocked. Maybe you just got lucky the first time, and now that lucks run out?

Dont you think that 1.9 ghz is a bit dumb... You might (have) damage(d) your cpu by doing that. If i would oc my 3ghz pc to 5ghz without cooling modification i would fry it in half an hour.
I mean cmmon use your brain. Oc it to smth logical like 30% (1.3 ghz) and you will not have such problems .... Sorry, but that just sounded plain stupid to me

I use SetCpu and every time it recognizes automaticly some speeds and I use them. The manual setup is bit beyond my knowledge.
The while was something like 3 days or so. Hard to remember. But still wayy more than like few minutes. I will try to set SetCPU manually, thx!

I know 1.9ghz is dumb. I used it back then only in short bursts. Usually scaling "interactive" between 245mhz - 1.5Ghz. Now even that is too much for most kernels. I thought that the freeze is caused by the CPU protecting itself from getting damaged or something, but not sure.
Still if the CPU was damaged, why would Quattro beta 6 kernel run at 1.6ghz without overheat or anything and RC3 kernel freezes at 1.1Ghz when try to load something more than homescreen..
I would use beta 6 kernel for quattro, but it does not support wifi in RC3.. Virtuous team made some changes to kernel at beta 7 and I would love to know what changes..

Overclocking the 8.9 Galaxy Tablet

Hey guys,
Posted under general questions and to my surprise not one reply in a week. So, I'm curious to know somethings about overclocking these tablets. What settings are you using? Have you had any issues with overheating and shutting down?What settings are recommended for web browsing, gaming etc? Let's talk linpack and benchmark testing. Where do you rank and how did you get there? Let's talk SetCPU benchmark scores, what kind of results can you squeeze out out of your device? How does someone pull off 41916.7 MFLOPS?! (Nexus) I'll start......
GT-7310 Running 3.2 / Motley Kernal / SetCPU
SetCPU Scores
Long Bench @ 178ms / Native @ 621.5ms
Linpack Scores
Single thread @ 42.4 MFLOPS / Multi thread @ 83.2 MFLOPS
Obtained running 1504MHz max / 216MHz min
Note: I have overheated and shutdown at 1504 web browsing. At 1400MHz I have had no issues. I see some scores are through the roof. I'm not to familiar with Overclocking and just would like to hear what you guys have to say. Thanks in advance. I may of posted this in the wrong area and I apologize. I would like this to be a thread on the topic rather than a Q & A.

Well I personally run my tab @1200Mhz with -25mV on the 1000&1200 steps, but anyhow, due to the interactive governor the most used setps are 216, 456 and 1200. I don't undervolt the lower test for stability reasons as I mostly work on the tablet so I don't want to test yet how low uV can go, don't have the time to test it right now. (Even though I'm pretty sure -25mV even on lower steps is still largely stable)
As for the set CPU test I tried them out on 1504Mhz: 150 and 595ms. I once pushed the tab to 1600Mhz but it ended up in an immediate freeze so I will skip on trying that again.
I don't have linpack but tried running GLBench 2.1 Egypt and the score was pretty embarrasing

Thanks for sharing. Since my post I have flashed aokp-34 galaxiansoup with v-3 of the Motley Kernal. Running 1400 on 216 no undervolting and am seeing a tiny increase in numbers. I'm still stumped on these linpack scores. This thing runs great. No complaints whatsoever. Anyone want to chime in on the best bench testing app or what the stock numbers on these 7310's are?

everyone will tell you that benchmark scores aren't very representative!
run the test 5 times and each time you will get a slightly different score.
i don't really care about benchmarking, as long as i feel that my tab runs smooth (which i think it does) im pretty happy. im normally at 1,4ghz and everything is smooth and stable!

Thanks for sharing. I couldn't agree more. My tab runs great at the same speed settings as yours. I just don't understand the numbers and how certain device's have like 100 times my mflops......I'm a numbers guy by nature, I like to see it on paper....but I am content with my device. Just always looking to make it cleaner and faster.....you know the addiction I'm sure.

Are you happy with this kernel? I found it stuttering and laggy...

Yes, I've not ran into any issues. Totally impressed and content with v3 motley. If there is a better kernel out there I'd love to hear about. I have yet to look, no need.

Been running a few custom profiles via Setcpu peaking @1.5GHz on B37 for a few weeks now. Other than a force close or two and an occasional browser freeze, which is normal with these roms, this thing is running pretty snappy. Gotta watch the temp though.

I sure hope that you've set up your profiles so that your tab overclocks to 1.5Ghz only occasionally, it's a thing that you HW can handle it, but will it on the long term?
Also, I regret that you can't overclock the bus frequency to get an overall performance boost (the GPU could really use it..) as on the Galaxy S

Yeah, I'm only pushing 1.5 on occasion, per profile. I normally run 1.4 all day everyday for the last 3 months with heavy use and no issues. Just gotta watch the temp. I've had mine to 113 degrees which kinda scared me.
