I use the phone overclocked and non overclock and i cant seem to notice a difference at all in the phones preformance. At stock speeds it is just as fast as overclocked. There doesnt seem any difference in noticable speed of overclocking to me. Do any of you notice a difference.
i see a difference on some of the more laggy roms but it is small. think about it, the most you can see is a posible 20% at 1200mhz and with cpu scaling it isn't that often it usses 1200. although that is significant you still have the same memory bandwidth and file read/write speeds. the responsiveness difference in the kernel has more to do with available ram and kernel hz. as well as aggressiveness in cpu throttling.
overclocking is more for benchmarks and bragging rights. it's for those that need to tweak and whatever or those that need to say theres is better. i can turn the phone down to 600mhz on the old 2.1 kernels that had that step added in before i could notice and it still wasnt laggy much beyond the normal touchwiz. even 400 was usable.
now if the phone is older and the os and apps push the boundries of its capabilities by all means overclock to keep up with the times. otherwise it is preference for your own personal reasons. i do it to test what the phone is capable of. but i often have it disabled.
there is power locked away in these phones that we havent seen yet, the 3d processor can run opengl at framerates better than older laptops i have used and after all these months no other manufacturer has felt the need to compete with it. some open gl benchmarks are fully twice as high as a droid 2/x and 20% better than the newest htc phones running qualcom chips and even the motorolas are considered to have a power gpu. it is a great gaming platform as is and the gpu is stable at 11% overclock, some phones at 25% overclock and maybe beyond. if you flash a custom rom that doesnt lag and do the whole ext4 or jfs conversion you should be happy with the performance of the phone untill your contract is up and maybe beyond. the technology is accelerating faster than the software.
after honeycomb and dualcore platforms hit the shelves then the software that will take advantage of our hidden power will start to roll out. at this time too many android phones are running at 500-600 mhz with little opengl capability, even the popular 1ghz snapdragon phones like the evo as well as they benchmark cant run 3d applications very well and there popularity is holding up software devlopment is some way. there isnt much money in apps that only run on the top 5% of the phones out there. we will have to wait till the droid2/x galaxy s and g2 and mt4g are the norm and there are faster platforms available before we see great differences in overclocking. maybe honeycomb or whatever comes after that will use some opengl in the ui or something, who knows.

agreed
overclocking seems pretty pointless at this point other than bragging rights
the only situation i can see it being handy are game emulators
Don't forget HQ flash streams on the browser, like some on justin.tv. My personal experience was that at 1 ghz it was a little bit choppy, and according to the rom as well, somewhere between 1.2 and 1.4 it becomes really smooth. Though if I used skyfire to watch it is smooth at stock speed, but some quality is lost in the optimization.
Am I the only one that thinks there is a difference at this? I also think the performance on heavy flash web pages improves when I use oc.
I have not seen any real difference in other than flash performance though... But I was kind of expecting this since in my desktop I had to use oc for it to work smoother as well.

So after reading nearly 5 hours and spending my time in the wee hours of morning, I finally did all the "stable" mods for the phone... If you haven't been reading, make sure you guys check out the stuff in the development forum.
After all modifications, I was able to get 2701 points in quadrant benchmark. What mods did I do?
-i9000 eclair flash (JM5)

-Alternative mimocans lag fix

-One click root (googled it for i9000)
-Overclock kernel 1.0Ghz to 1.2Ghz

This stuff really does help out your phone folks. Bench it now with quadrant, then take a peak at the other stuff and make magic happen. If anyone needs any additional help setting up their captivate, I'm more than happy to help.
I agree those fixes help speed a lot. But the quadrant score is meaningless. the speed hack creates an io loopback. The loopback just tells quadrant what it wants to hear.
Does your BT work on the european ROM. For me all people hear is a gargeled mess on there end?

I keep hearing about this quadrant, does it actually improve real world performance? Or is just for the sake of scores?

Quadrant is just benchmarking software that takes the cpu, gpu and memory read/write speeds into account. It runs a series of tests and spits a score number out at the end, so you can compare your device to others (like comparing boner sizes, but less gay).
It doesn't actually do anything to speed up the device though.

This is correct and to be honest there is way to much weight in the I/O tests. That is the only reason that the stock Droid X bests the Gal X. It has more weight than cpu and gpu so you can't put to much into those scores. They really don't mean anything more than bragging rights. What I am interested in is real world usage.
Real world use with the hack provides amazing speed gains opening and switching apps. Io heavy apps are very much improved while open too. It's finally as fast as the iphone.
Whats your battery life like after the overclock?
The score ended up getting lower and lower every time i used quadrant. 2701 is the highest I was able to get so far, but that's with a fresh install of the rom and all the stuff before I started loading on apps. Everytime I ran the benchmark, I of course killed the apps beforehand.
The battery life is the same- to be honest. This is me comparing a rooted stock ROM to the somewhat fresh install of the eclair i9000. The phone is very snappy. I came from an iPhone 4 and one of the biggest eye sores to me was the less-fluidness of changing programs, response to buttons (homescreen-back button) and pinch to zoom. After all these changes, it's a whole different story. Browsing is very appealing, especially since pinch to zoom isn't jagged or slow. The smoothness of this functionality is on par to an iPhone. And there is no waiting when I press the home button or back button.
True, maybe these numbers aren't considerably accurate (as far as the lag fix and EXT2) but at least it shows raw computing capability in it's current state... meaning, the usage of a virtual EXT2. Never the less, the phone is still all around faster, even if it isn't exactly the proper way of going about it.
The only problem I've seen so far is that it likes to randomly shut off. Won't respond to anything unless if I soft reset it. I haven't really found what causes it, since the consistency of it happening goes about in a non set pattern.
I didn't see any real world increase .. so I reverted back in about 4 hours.... I'd rather have the memory than a number that don't transfer to real world speeds...
I read a lot of comments about the processor used by qualcomm being asymmetrical thus one core is doing the heavy lifting most of the time while the other is at a lower clock speed and it affects overall performance but enhances battery life. Now that this is a big factor on why the performance and benchmarks are lower than tegra and exynos because its running on one core most of the time.
NOW.... When we get s-off and are able to mess with the kernel, cpu speeds and such. Can there be the possibility where we can use a tool like setcpu to force both cores to run at the same clock speed always? This might level the playing field and show some drastic performance enhancements imo.
Theoretically... Is there a slightest chance something like this can be done? I suppose so since we can manipulate the cpu so easily with kernel access
Please input
nothing? lol
this might be harder than i thought...

I don't think gingerbread has the capability even if the kernel was modified.
We can only wait and see
IMHO, with proper kernel, system will manage cores better and there will not be any lag. Asymmetrical core scaling will yield much better battery life then symmetrical one, just need better implementation.
I have an overclocked Samsung Epic and it the improvement in speed in everyday use is significant. Because the processor voltage is set lower than stock there is no sacrifice in battery life. With the Asus Transformer do you get a definite and significant benefit from overclocking? I am not talking about test bench scores but real world noticeable responsiveness. When I skim through the forums it is difficult for me to tell? Some people swear by sticking with stock. I would appreciate others perspectives.
Thanks
The improvements from overclocking vary on the application.
Home screen switching is choppy regardless of overclocking simply because the launcher lacks optimization. Browser performance is improved a little bit, but mainly remains unchanged as well. Games run noticeably smoother, especially Fpse. Task switching gets a small boost, as some applications will be able to load faster.
If you're a big gamer, overclocking is definitely worth it. For everything else, it won't make much of a difference.
I haven't played too many games (mostly Stardunk and Stupid Zombies) on my TF, but I haven't noticed any issues with them. I have also played high profile 720p video with absolutely no stuttering or artefacts.
In other words, I haven't felt the need to overclock yet. But if you are doing heavy gaming and/or video processing of some kind, it might be worthwhile.
For me, there's hardly any need to OC. It all depends on what you wanna do. To many people who play a lot of games on their TF, they report increases in performance (especially with emulators) but on other things I never really noticed any difference. I'm currently underclocking my TF, and have been for about a week, with no noticable stutters or performance issues and have great battery life.
And it's not really an "effort" to flash a new kernel... the hardest thing is waiting for your device to boot up again...
I have a transformer, galaxy tab 10.1, and a xoom. I've used just about every kernel that can be overclocked for each one of them, and to be honest I haven't really seen any improvements from them. I don't really play many games on my tablets though, so maybe there really is some benefit in that area.
Galaxy's screen
How do you rate the screen of the Galaxy Tab 10.1? Is it as good as the Super AmoLED (+)'s from Samsung mobiles?

This seems so counter-intuitive to me. If you overclock a PC CPU there is a very direct correlation with performance. There are always limiting factors such HD acess, etc., but there is a definite and noticeable difference across applications. What is even more surprising is that we are talking about very large % increases vs what people can do in the PC world. People are overclocking these CPUs by 50% plus...You would think you would see a very noticeable improvement but that doesn't seem to be the case.
My main interest is in browser performance. For example, XDA forum pages load extremely slow in all browsers I have tried (stock, Opera, Dolfin) with 5-6s to refresh vs instant on desktop browser. Also flash video tends to freeze and stutter some times. My internet connection is over 20Mb/s down and 5Mb/s up. I was hoping that I would find overclocking safe and provide a noticeable improvement.

Overclocking can be a bit like collecting .. 'string' , because it is mostly done for the sake of itself, kind of like the many Ham Radio fans who talk about their "rigs", etc etc.
Yeah, of course if you can get, like in the old old days, a celeron 300 that overclocks to 450, and is dead stable, it was noticeable, and if you had a droid 1, which overclocked (many did) with ease from 500 to 1000+ , then it was again, noticeable, just not a staggeringly 2 times increase, because there are too many other factors.
The number of bus errors, and retries and slowness of the original bus speeds, and other components makes for a not-quite-as-expected by the numbers 'increase'. I would still mess with it, but not for the obvious reasons. I like under-volting more, and over-clocking only the slightest bit where nothing ever crashes or FCs. The moment you overclock, you really shouldn't be asking questions about 'Why does blah blah netflix crash?' because it crashes because you overclocked, and nothing else matters until you stick a kernel back at stock in there.
The other thing I love about alternate kernels is that you've got control of what modules you either compile in or compile and load as .ko files. cifs, tun, ntfs, whatever, it is all very useful, so there are lots of good and not-as-good things about it.
One thing I hate is when a dev insists on creating a kernel that has a 'default' speed greater than stock so that you've instantly got an ordeal if you've got one of the many gizmos that will not overclock to his default (like 1.6 to pick a number out of a hat).. Just make them all start at default, then allow us , the users, to setup overclocking via testing with setcpu or some such thing. Much easier than basically bricking things right off.
I sometimes look at those guys that overclock 'seriously' (by 3-4 times) using a container of liquid nitrogen that lasts for ~5 minutes and it is all for bragging rights, setting records , etc and think they're insane, but that is also part of it. Some are happy if they can just post here that they got 9,000 mF on some test despite not being able to do anything else reliably.

Great post!

Very philosophical ! ;-)
I guess what I am getting at is if you overclock to 1.2Ghz-1.3Ghz on the Transformer can you have a stable system that shows an appreciable improvement in responsiveness? Moving from hypothetical to actual...have you done this? Any specific kernel?
The engineer in me is looking for a definitive answer. ;-)
Thanks.

Yeah, I've done this, just not on the TF yet. I'm working on a kernel right now that doesn't have OC built-in and activated at boot, so that we can use setcpu to screw around with it and find that 'sweet spot' that works for us, also under-over-volting. What I'd really like is to build in all the modules I like, setup over/under-clocking-volting and have it boot at 1 G. I mean, a dual-core 1G is nothing to sneeze at, and then try to ramp it up without screwing with over-volting immediately. I never like other peoples ROMs or Kernels because they have made their own crazy judgement calls. I like my own crazy judgement calls
Here's what I've noticed: When you have 'up-to-date' technology , as we do, in the TF, then overclocking that is totally stable makes a difference and it is noticeable. For me it's the FC's that kill the deal, but this chip and box appear to have plenty of headroom so I'm guessing that 1.2, 1.3, 1.4 are all good possibilities.
Example: My HTC Incredible phone has been overclocked to 1.1 from 1.0G for ~a year or so, and it doesn't FC, and it is faster, noticeably than at 1. It's only a 10% increase and yet it feels much quicker, so go figure. Those things are also subjective, so grain of salt... Example2: A stock droid1 is one I took to a double overclock, 550 to 1000, and yes it was faster at some things, but the underlying infrastructure didn't really support the faster CPU so I really never noticed a 100% increase that matched the clock speed. I left it that way for a year without any damages and it still boots up fine at 1 G.
In another post I started, I was asking what keys were required to boot 'safe mode' which exists in android OSs, and if I knew that, I'd try one of the OC'd kernels right now. IF not, I don't feel like unbricking again.
If you're interested, here's a good link for building your own: (generic android, not TF really:
http://www.droidforums.net/forum/rescue-squad-guides/31452-how-compile-your-own-kernel.html
Thanks for the response. With such a large community of Transformer users I am hoping to find a solid, conservative kernel that I can overclock with. Creating one myself is beyond my current technical capabilities.
I am considering using a custom ROM on the transformer, but is it worth it, I am mainly after performance increases. I see on a few that there are higher benchmark results, but does this actually translate into a real world speed increase?
I remember some custom ROMs for the original i9000 Galaxy S doubled the benchmark performance, but that was more down to "cheating" the benchmark than anything else, although it certainly was noticeable at times.
One of the slight criticisms I have of the TF101 is a slight amount of lag / lack of responsiveness occasionally - not a deal breaker, but if it can be improved then why not? Obviously not at the cost of stability though.
I think the SGS2 has spoiled me a bit here!
apparently there is a big increase (mostly from overclocking). i had the standard firmware for 3 days only, so I can't really tell, but one of my co-workers has a locked B70 and was wow-ed by my TF, the smoothness and speed of it.
Yes, I'm waiting too, to root it and put a cutom ROM on. I read, heard and saw the performance difference. Mainly from the overclock, but also thanks to kernel tweaks and stuff. So If you can root, do it

I've never been that keen on the idea of overclocking, as I prefer to have a bit of headroom, but I guess if it is safe and makes a big difference, then I would give it a shot. What would be a good middle ground for stability / speed ?
1.4 IMO is very stable and doesn't increase heat or use more battery but the real world performance is noticable. I have never run a benchmark so I can't give you any numbers. Just my normal use.
Cheers for the reply.
Is there any one ROM that stands out as being the best performing?
Contrary to what people think they all perform about the same. There is no source so everyone is building of the same stock rom. If you want the same look then go with Revolution. If you want a little tweaked then go with Prime (What I'm on). If you want the tweaks and a nice tools package then go with Revolver (What I was just running). All 3 devs are really responsive to problems
If you start from a clean base and don't restore any system data from other builds then they will all be fast. The real speed difference is in the kernel and those can be flashed seperately from the rom. Clemsyn is really putting out kernels this week. Some good. Some not so good. Go with whats right for you.
EDIT: I have actually installed all 3 roms in the last week and run them at stock and at 1.4 Ghz. They all performed exactly the same for me. They were all equally stable. I don't use benchmarks because they can be fudged.
I've used all three too. I notice huge improvements with webpage rendering. It's almost as fast as my laptop, where as before I avoided using the browser if possible. The ability to hide the status bar is a really nice addition to the latest version of revolver.
Edit: autorotate is also alot faster.

There is no such thing as an overclocking "middle ground" when dealing with mobile chipsets such as the Tegra. It's not like overclocking a desktop computer where the CPU will constantly run at the specified speed; mobile chipsets are pre-configured to utilize only as much power as necessary. For that reason I always ramp up my tablet to the max clock speed it can reliably handle, because then the governor will handle balancing between speed, stability, and battery life. My clock speed can range from 216Mhz to 1624Mhz, and on the interactive governor I can still achieve a good 8 hours of battery life from a single charge.
Of course that's not to say that you couldn't constantly run at 1624Mhz all the time, and I do sometimes lock it to that speed for games. But for much of the OS interaction, it's not necessary to run at full speed all the time, and you won't notice a difference even if it is locked at full speed. It just comes in handy every once in a while for things like loading apps, loading web pages, and playing games.
I have the highest score listed at 3300. What I'm asking is for people to start downloading AnTuTu Benchmark and running benchmarks while overclocked at 1.152 GHz, see if the score reaches over mine. I want do some research about our phones, but the more scores that are in, the easier and faster ill be able to compile my findings, and come up with something to further increase performance.

Benchmarks are bull****. Each value will come up differently depending on what is going on in the background and how Android chose to throttle the CPU while the benchmark was running...
Beyond that...
Overclocking this device is a known source of instability and most devices will crash under heavy load.
Also, I expect the heat will eventually cause issues when using GPS.
Any device is only as good as the weakest link and you are not increasing the speed of the memory, GPU, or the busses on the board.
What you are doing is increasing the heat inside the case above what the heatsinks are designed to handle and causing timing/sync issues.
There have been times in the past that a manufacturer saved money by producing a large amount of one chip and used it in many devices. In that kind of situation, the chip was sometimes "underclocked" and put in budget devices. I can assure you that is not the case with the Sidekick 4g.
Overclocking is an interesting idea in a large PC because there is plenty of room and accessories available. This device is not a PC.
Sorry, didn't see your reply sooner, been busy with the ROM and general life crap. But yes, too fast and you lag, but with the right overclock, you won't get too hot, but a notice a fair amount of increase. Though yes, I only overclock when need be due to increased battery drain. Regardless, I'm doing limit testing for stability purposes, speed purposes, and because I may attempt at one point to see what I can do about coworking 2.3 at the very least before switching over to the G2. After college starts, I won't be on here much at all.
