2.0 Ghz kernel

Hai Guise!
Back a little while ago the G2/Vision thread (before Desire Z was merged) had a thread about overclocking made by a user named Flippy. I followed it for a while because it was getting insanely out of control and awesome. I had used 1.9Ghz as my max oc for a while and It was great. Now I'm on 1.8Ghz again because the 1.9Ghz kernel was removed later on and replaced with the 1.8Ghz update zip. (For some reason doesn't work for me so I had to fastboot it)
So the reason I made this thread is because I would like to have the 2.0Ghz kernel. I know it's possible and has been done already. I've looked into compiling my own but apparently I need linux to compile it and I'm not fond of installing VM's on my old computer that will barely run as it is.
Now I ask of you, if anyone who is kind enough to possibly please compile a 2.0Ghz zimage for me, I would be greatly in your debt and appreciate it much so! I understand that it is my fault if I mess up my device and only I am held responsible.
Thank you in advanced to anyone kind enough to offer their services.

Why do you need to overclock that high? I've used the 1.8Ghz and found that to.be overkill. I'm running at about 1ghz at that seems ample.

Wouldn't that fry your phone without any active cooling system or something? Sounds unnecessarily risky..

You don't need a VM. You need to wipe the garbage off and install linux on the "bare metal".

While it would be *neat* to oc this phone to 2GHz - just because. It would be beyond useless and I can just see some noob burning down their parents house or possibly starting a nuclear war with Russia by accident. Lets not forget your carrier reporting you to the CIA for having a nuclear reactor in your phone.
Look, with no active cooling it's just downright stupid to go that high. However being the genius' that we are I'm sure somebody could devise a method to install a mini fan or some liquid cooling on this phone. But then you may need that nuclear reactor to power all that stuff. Haven't we already set a guiness world record at 1.8GHz on a production phone anyway? Maybe we need to tell them so we can make it in the book

My phone froze at 2Ghz... I went in for 2.2Ghz at first but it froze after a couple seconds

LOL, it didn't make you go back in time or some ****?

The 1.9Ghz kernel caused my phone to crash. 2.0 would burn your phone's processor out. Just use the 1.8Ghz kernel and have the profiles on SetCPU set to the lowest speeds when the display's off.

Your phone may not actually run stable at 2GHz. Mine doesn't run stable past 1.6GHz, and that runs psx4droid *perfectly*, especially with the optimization they've done in the app recently.
Also, even with setCPU profiles, battery drain when you ARE running that high is a beeeotch.

Honestly, it's not really for OCing that high, but rather the look at what I can do I had a friend just ask be how high I can OC my phone and at 1.5GHz he's like woah :O His face at 2GHz would have been like

I previously used Flippy's kernel on my G2 and did OC it to 1.8 GHz, and got a Quadrant score of 3037. It was cool to see how fast my phone could actually get, but I'm more than comfortable with OC'ing it to 1.4 GHz. Anything more than that seems to be unnecessary to me, but that's just my opinion. Last thing I want is to have my G2 melt while it's in the pocket of my pants.

Oh yeah totally forgot that existed. Thank you for the useful response.

tried the module but the phone freezes after doing anything above 1.4ghz
I believe it needs voltage tweaking which I don't know how to go about sooo... yeah

Nope, not for me anyway. I know different HW revisions and such have an effect on how high you can oc but my phone doesn't skip a beat at 1.8GHZ. I'm sure I could go to 2GHZ or a bit higher but unless I'm trying to emulate a PS3, I don't see the purpose - aside from maybe setting a record.

Same. I can do 1.8 all day if I keep near a charger. Anything over 1.3 will drain my battery like a monster though.
I keep at 1.2 regularly and only go higher for games.

I can jog 1.8 and 1.9Ghz for a day without even reaching a dangerous temperature.
Can I get some supportive ideas and less herp derp personal opinions?

Highest Ive pushed mine is 1.5ghz. No need to go any further, Im satisfied with the performance. I get a full days battery life and the temperatures never get critical (my setcpu profile is set to underclock at 38.2 degrees Celcius but my G2 hasn't gotten close to that). Im curious at what stage my G2 would score 3000+ in Quadrant.

You might PM flippy and see if he will customize a kernel for you that goes that high. Let him know you will send a certified letter signed in blood and a video of you stating you release him of all liability for what ever town you destroy when your phone goes nuclear.
Seriously though, I'm willing to be he'll make it for kicks if you ask nicely - btw, call guiness so you can make it into the record books. Also, I'm not sure but if you flash a 'blank' kernel couldn't you just echo the speed and voltage in the 00banner file or whichever one it is?

[Q] Overclocking the Evo past 1.19

So, Im sure this was answered somewhere, and I searched all over.
With that said, why cant the Evo be overclocked past the standard 1.19 or 1.2? I know stability is an issue, but there are other ARM processors that can OC almost double. Is the Evo ARM processor just not able to handle anything past that?
Does anyone know?
Thank you for the insite

You cannot compare the processor in teh Evo to other similar processors. Every single processor is different, and overclocking the evo past those speeds could brick it.

Why would you want to overclock that far? The Evo has no ventilation and crappy power management, even with an extended battery. You're taking an already unstable system and pushing it to the edge. Not only will your phone overheat and freeze, but you can permanently damage the hardware.

I know every processor is different and each one has their own limits.
There is always a risk of bricking and damaging the actual hardware, but what im asking is, in theory, and a practical test, can you push the evo processor past the 1.19 that seems to be the limit (im not talking about going huge, but is there a possibility of being able to hit the 1.5Ghz?). Because there are certain frequencies that are not stable, but ones slightly past that could be stable.
Just throwing it out there.

A car traveling at 120 MPH is not as easy to control as a car doing the speed limit.

I was wondering this too. It would be nice to have the option to push it over 1.19ghz, I'll be the test dummy.

My Evo can handle 1228 fairly well but can tell its not as stable as say 1190. 1190 MHz is no prob...1267 usually crashes after a run or 3 in quadrant. 1113 runs niiiice for me and my 0004 evo

I can run 1190 just fine. Can a Dev possibly create a kernel that allows us to go past 1.2whatever.

I can't go up to 1.19 stabley
Gimme a couple a days to come up with a new sig that is cool.

if I pass 1190 endless bootloop.... then ya gotta be fast and turn that damn thing down

I can go to 1228 MHz with Tiamat but it will crash and reboot once you do a couple of things.

despite the meriad of answers you have gotten, I have been running my Evo on Sprint lovers Rom, and KiNgxKernel-Evo-12-BFS357-2.6.32.25-Flashable.zip for kernal.
I have been overclocked at 1267 since the day the kernal came out. it is singularly the only kernal that has allowed me to do this without ever crashing. OH, and I'm using
SetCPU 1267 on both min and max and scaling set to performance.

Not going too big? Going from 1.0 ghz to 1.5ghz on a phone is like going from a civic to a v8. Alot of computer cpu's dont even overclock 500 mhz. I think you're expecting a little too much from a phone. If you want more, go buy a dual-core cpu atrix 4g or something. I'm a speed freak myself when it comes to cpu overclocking (mainly on computers) but 1.113 is plenty for a phone. It even runs fine at 600mhz. Dont get me wrong, it would be cool to get it that high, but your phone would hate you lol

Until HTC drops source codes you will lose camera and other things.

How did you overclock the CPU? I have tried the setCPU and it does not work, I have my Phone rooted, installed the crazy UNleashed rom (since uninstalled) and could not get the setCPU to overclock. Even though UNleashed is made to do that, and I have read others getting over clocked. I am running Synergy now, which I do not think it can Overclock the EVO, but I would like to know how you fine folks are accomplishing this. I would love to go 1.1 right now.

[REQUEST] A Upgraded-Overclocked Kernel

Hello, after running all the kernels currently available for kindle fire, I cant help but noticing that none can clock up to more then 1200mhz. While this is an improvement, I would liek to see a kernel that could overclock all the way up to about 1400-1600mhz. I am sure that the kindle could handle it, It does fine with 1200mhz. Any thoughts, anyone think the kindle could handle this. If so, whats stopping all these great devs?

What a great thread to start. While we're at, here's what I'd "liek" to see: push the CPU to 3 cores. And can we get a higher pixel density, devs? I mean, come on!

My understanding is that no one will release a kernel OC'd to more than 1200 because it's dangerous. Even if some Kindle's can handle it, some can't even handle 1200, and it would cause too many problems with people breaking things. If you want it that bad you'll learn how to compile your own kernel.

This is the development section. Not the Q&A/General. If you would like something, please try it yourself. Remember, everyone does this for free and as a hobby.

What hasoon said...
What Jake said is correct also, it would take waay too much work to get an overclocked kernel stable enough for the masses. Lower frequencies are generally more easily overclocked to higher levels than already high frequencies are.
Plus, why would you even want to overclock, what app/game is it that needs more than our 1.2ghz can handle, especially since we have a dual core cpu? I can't think of any and I have over 900 apps/games.(Not all on my KF, of course)
All it would do is drain your battery faster. Even games like NOVA 2 & NOVA 3(Probably not the most resource intensive games, but you get the point) run fine on 600 and 800 mhz.
Tl;dr:
There would be little to no benefit in furthur overclocking our KF's.

I agree, I use the "Kindle" at a frequency of 800MHz, and I have enough speed for gaming and work)
But that should be added, so this optimization core to increase the autonomy of the "Kindl"

0xD34D had a 2.6x capable of 1.3ghz. Worked well, I had no issues.
If your still stock ROM look it up although some will say it's "dated".
Keep in mind just because it's clocked higher does'nt mean it's faster.
At 1.3ghz it felt OK but benchmarked well below 1.2ghz, something I've noticed on my G-Nex as well. Once over a certain speed performance drops.

Jr member. Hahaha

What's the point in posting crap like this other than to be a troll?

Short answer is no, it's not going to happen.
All trolling aside half our devs didn't even want to go to 1.2
Do to differences in device state / hardware race (yes there are some differences in hardware albeit small and not expected by Amazon to be noticeable in stock, that obviously changes when you start changing the OS), there's no way to know who's kindle will support what clock speeds.
If that's not enough for you let's consider that TI clocked it at 1024M for a reason and that any manipulation beyond the MFG specs is going to run the risk of shortening the devices life. You'd get a similar response from me if you are talking real PCs as well. Quite frankly the risks of high OC are not worth the reward, for any device IMHO

Requests go in Q&A (moved)

any one here can be a "dev" with learning and patience.
if we don't take it upon ourselves then we can't rightly complain with what's available.
with that said i will. i personally do't agree with the argument that it's not good for the device, some can't handle it, etc., so it's not done.
My gnex with the latest faux123 kernel can be set as high as 1.8ghz.
i cant get past 1.35 without a massive hit to performance, same with any other kernel that allow crazy high clock settings. there's a few.
At 1.56ghz it locks up. i don't blame faux123 for the instability at those speeds.
when battery life isn't a concern i'm clocked at 1.35ghz. i won't blame him if the phone stops working either.
I like that he put it there allowing me to try it. it's fun to push the limits. this is about fun.
There's a demand for oc'ing everything. I'd do the same with the KF, although from the 0xD4aD kernel i already know my KF was perfectly stable at 1.3ghz even with uv.
i wish i had the patience but sadly i don't so I wait.

2.1Ghz Overclock like on HTC One XL

Hey guy's I noticed the one xl just got kernel sources recently and the result? Insane oc! I was just wondering how hard it would be to match the 2.1 frequency on the galaxy s3 lte as they both run Qualcomm s4's.

The 1.9Ghz we currently have isn't enough for you? !!

Ahaha, well the thing is I returned my one xl for a galaxy s3 for performance reasons. I love to get every bit of power I can from my device and I somewhat expected the s4 to hit the 2ghz barrier soon after it was fiddled with. Battery drain is not a deal breaker for me.

Way more simpler actually.An app shows you your available frequencies choose the one you want and done.Oh and its live OC to.

Overclocking a phone is not easier than overclocking a PC.
Phones have many CPU steps so you have to find the right voltage for each step.
Also you can only change CPU voltage and frequency. (Some kernels allow you to change bus speed which is nice but alot don't support this.)
The only sensor you have is battery temp.
Furthermore, when overclocking a pc, you can just run prime95 for 10 hours and you know your stable. With the phone there is no difinitive stability test so sometimes something might trigger an instability afte you have been "stable" for a while.
Also no third party cooling. (As far as I know)
Im not saying it's really hard, but honestly when you come from PC overclocking you will probobly get frustrated about some things.
All that being said, overclocking a phone is super fun and I hope I didn't scare you away from it in any way.

Am I the only one who isnt interested in overclocking in the least bit? I mean, the damn thing is fast enough already. I can understand overclocking something old like a nexus one, but wow. What do you guys get out of OC? What do you use OC for that requires the higher speeds?

I custom built my computer, im sure i can overclock it to who knows what but it being so new i don't even think about it. Maybe in 2 years when it starts showing age.

Most people that overclock their PC will get a new one before they really need the speed anyway. It's just because its is fun. And plus if you know how to overclock, there is really no reason not to. It's not like it's a trade off, its just free performance.

gotcha, i wasnt meaning to be disrespectful, i just never understood it unless needed.

You should try overclocking your PC. You might find that it is very fun.

I wish I could but I have a laptop plus have no experience in OC a pc.

Your right about that. If your not pushing it to it's limits its easy. But then again the same could be said for PCs.

Why is the default voltage so damn high?

I get having it be higher than necessary to avoid bugs... but the 153mhz CORE slot can go to 90mV down from 8-900. That's 1/10th of the original voltage. Why would Google/Samsung ship it using so much more than what it needs?

Those are MAX voltages...and I call hogwash on the 90mV, unless you are disabling smart reflex. Then I would want to see some actual proof.

Lower than 70mV is unstable. I didn't disable smartreflex, but even if I do it makes no difference. Maybe someone else can share their lowest voltage for this. I'm sure I'm undervolting it as it becomes quite unstable if I input 60mV, so obviously something's happening.
Yes, they're max voltages, but even with SR it doesn't go below 886 or something.

I find that tough to swallow. Did you actually verify the voltage with a kernel log?

What's the easiest way to do that? I'd like to confirm it myself. Like I said, I know it's doing something because at 50-60mV there are instant issues.

You have to disable smart reflex for your voltage settings to work. It isn't going down to 90mv. Disable smart reflex and then set that, I doubt your phone will run.

Voltage Nominal=75000, Calib=75---, margin=38000
Seems to be the most relevant. And yeah, I've got it at 75 right now.
And I've disabled SR as well, it doesn't change anything. And the voltage settings definitely do work witohut disabling it as, like I said, going too far down will cause a crash. So obviously it's doing something.
Have you guys tried undervolting that far?
And I'm doing this with franco kernel updater. The widget is showing the Core voltage to be 75.

thats 900mV and 750mV. and there is a large variation between individual devices. some can handle much less and some cant handle a tiny bit less. but undervolting too much will end up using more battery to achieve what it needs to achieve from working longer/harder to get there. 90mV without or even with smart relex will cause your phone to freeze then reboot.

Why? I know that underclocking would do this - the time to finish a task at a lower clockspeed is longer.
I don't see how lowering the mV can possibly increase battery usage.

But mine isn't freezing until I put it at 60-70,V.

Not according to the app.

Hopefully this attached a screenshot.

no, you are right. i didnt see that you mentioned core. after looking at the original post i see the core now. anyways, at that low a voltage it will operate, but wont be fully functional.

anyways, i dont know what that app is reporting, but franco kernel can only be set to a minimum of 830mV. looks like a mistake or a bug in his app. im gonna email him.. https://bitbucket.org/franciscofran...e9aa9b26/arch/arm/mach-omap2/voltage.h#cl-184

It seems functional... I mean, clearly the GPU is working (and at that voltage according to the app) because the screen is on/ not artifacting.
Is it just incorrectly reporting it? Is there another way to confirm it? Dmesg was not clear.

check the link out that i just posted. franco kernel can only be set to a minimum of 830mV, the app is reporting wrong. its setting, but not actually setting https://bitbucket.org/franciscofran...e9aa9b26/arch/arm/mach-omap2/voltage.h#cl-184

So what is it actually setting it to? Because if I set it *too* low it still does give me errors... so how can it be both?

i think it gets set to 830. i let francisco know, we'll see what he says.

Alright. It's just weird. Because if anything under 830 is setting it to 830, and 830 is stable (because 95 shows stable) than how would 830 be unstable when the UI shows it as 40.
I mean, 90mV is kinda insane. It would definitely make sense if it were more like 830. It's just confusing.
Hopefully francisco can explain.

Hmm, then why does setting an absurd voltage like 200mV cause an instant reboot while I can set it to 830mV and it runs fine?

Yeah I can set it to 830mV and it runes fine. No issues until I drop to 60mV. I haven't reached a limit for any of them.
