So I've gotten anywhere between 2.5 to 5.1 MFLOPS using various ROMS and have yet to be able to notice something incredibly different.
710...768...806 - What does it matter? What program other than Linpack shows a sizable difference? Sure, maybe things open quicker? What am I missing here?
I read all this about achieving high MFLOPS and OC Kernels yet I still can't achieve smooth game play on 16 bit emulator on my phone with 5 MFLOPS.
MFLOPS mean jack when there is little way to observe the difference.

Linpack MFLOPS - measures the floating point performance of your phone.
710...768...806 - refers to CPU frequencies
increasing the CPU frequency should equate to better general-case performance, including things opening quicker as you mention, but also other types of general snappiness like moving between screens and so forth.
"I read all this about achieving high MFLOPS and OC Kernels yet I still can't achieve smooth game play on 16 bit emulator on my phone with 5 MFLOPS." - This may have less to do with the performance of your phone and more to do with the emulator itself. Emulation is a surprisingly CPU intensive operation, especially if the emulater isn't well written. Rather than looking a ton into overclocking and JIT, etc, maybe you ought to look for a better piece of software.
Yea,
I've tested most emulators. Wish there was an Atari emulator!
Thanks for the response.

Haha Awesome
it looks like to me that everyone is look at the wrong things.
for example:
I am running a Tom that is getting on a average of 4.9 mflops.
I get smoother screen changes....
streaming videos online is so much faster compared to a 3.0 mflop rom. ...
tubetube and other....... websites.
to me everything I do is faster...
I.don't play game on my phone so I don't know how that is.... but everythng else I do is very much faster.
I love high mflop roms...
I have notice about mflops is that it matters about the kernal that u use.
Isn't it true that the MSM7201 in our phones is already overclocked to get to 528mhz as it is? I see a lot of different places saying Qualcomm chips in general are just not worth overclocking... and since our chip is factory overclocked to begin with... just seems like we're pushing the already-pushed here. But the way this board goes crazy for overclocking... it's contradictory. I don't know what to think, cause I've run Linpack myself and gotten ~4.9 with JIT + OC versus ~2.5 without... but I'm with the OP on this one... only difference I'm seeing is my battery draining faster and my phone getting physically hotter.

I have OC and JIT and getting about 5.1 mflops and haven't had worse battery life or a hotter phone. It could be the battery I'm using but meh (got a replacement one that's 2000 mAh) but I got worse battery life on leak 2.1 than with the rom I'm using now that has OC, JIT, LWP, etc. I can go about 8 hours with heavy texting, moderate internet usage and my lwp's running and it only goes to about 65%
so OC and Jit don't make that big of a difference in gameplay?

What the OP and all the respondents are noting is frankly quite typical of what happens when performance tuning focuses on a single benchmark: the results obtained are essentially meaningless for different kinds of activities on the same device.
That's because there's a whole chain of dependencies that are specific to a given task, any number of which could become the rate-limiting factor; and a different task on the device will have a different set of dependencies and therefore different rate-limiting behaviors.
For instance, let's take writing to an SD card as an example: there's really no way that OC'ing will speed that up in a measurable way - because the CPU isn't the rate limiting factor.
That Linpack benchmark measures floating-point performance using a software library (as the Eris has no hardware FP capability). Most of the apps on the phone do very little FP work at all. But, it's not a bad test of CPU speed, because it performs no I/O. It also may not be very memory bandwidth intensive, either (if the problems it works on stays in the uP cache and there are few page faults).
OTOH, a game emulator needs to write to the graphics display (at a minimum) and possibly also do read I/O from flash.
Different task, different results. Sometimes things can be improved by hardware or firmware; sometimes the software itself needs to be improved.

Thanks for my laugh of the day on that one.
What I'm trying to get at is -
I should be able to play, at the basic level, Sonic or Mario - Without issues.
At the very least
I prefer roms over market games any day (Sonic, Mario, Zelda, DK-Country) and it cripples the phone, at least in my view, that I cannot enjoy the fruits of old games.
Although, I was able to find some old Atari games - which, thankfully, work without stuttering.
Ever since I got my hands on MIUI and the Glitch ML kernel, I've been amazed at the undervolt results I've been able to achieve.
I assume I'm not the only one messing around with their voltage settings, nor am I the only one doing so on the Glitch kernel.
Question is, how low can you go? My settings are in my signature, but how far have the rest of you Glitch folk been able to go using the ML or LL kernels? Post your results below!
For myself, I'm currently testing out the low end of the spectrum, seeing how low I can get the 100mhz and 200mhz range and still be stable. Even using 200/100 as my Screen Off profile. I never get sleep of death with Glitch ML.
Either no one reads the General forums, or few people care much for battery savings. Oh well.
It's not that, the lower the volts, the slower the phone. I'm undervolt; games lag
Sent from my GT-I9000 using Tapatalk
Why would undervolting lag the phone? I'm undervolting, not underclocking. Games I play are as snappy as they've ever been.
It depends on phone i cant go under 25 my other vibrant could go -200 on 100mhz

OP even if you crank it up to 1.6GHz, unless your isolating that step, your phones not using that clock speed unless your doing sh*t on your phone. It will increase how fast apps or menu's open navagating throughout the phone. Your making the CPU think faster so your phone ends up doing its tasks little and big ...faster

The benefits of overclocking you ask? Let me tell you just a few.
1. For every overclocked phone, one dollar is anonymously donated to poor and starving children, families, and college students across the world [citation needed].
2. Overclocking your phone emits a low frequency gamma wave inhibitor which in some cases, tested by prestigious scientists, has proven to protect you from harmful UV rays from the sun, nuclear fallout, increases neural synapse action in the brain, lowers bad cholesterol AND blood pressure, increases lifespan up to a minimum of three years, and is a natural antimicrobial agent that also interacts with your white blood cells to not only increase output and strength, but also breaks down the DNA rebuilding process by inhibiting protein synthesis in a wide variety of foreign microbes in your body.
3. Overclocking has been used to successfully treat sever depression, obesity, dementia, and AIDS.
4. With an overclocked phone, it's been observed waiting times for and inside elevators is severely decreased.
5. Bad driver? Accident prone? Overclocking has been shown to heighten driver awareness and overall skill.
6. It speeds up your phone on a day to day basis, with some, but not terribly noticeable battery drain [citation needed].

Overclocking is entertaining. But I'm running the Unnamed rom on my device and have it UNDER clocked to 800mhz. Crazy good battery life and zero lag.
Overclocking is pointless as it runs everything great already. I'm waiting to overclock until my phone is outdated and my contracts about to expire.
While its rather easy to do there really isn't any benefit to overclocking the SGSII. Yes, it'll run a little faster and your Angry Birds might run smoother (really? ), but it'll also mean a little more heat and more battery drain all to accomplish something you really won't be able to get any real advantage from.

For this phone, it's pretty much useless. The phone runs great without the faster clock speeds.
On the other hand, if it was a snapdragon processor, you'd need 1.5 GHz just to be marketable next to this phone (and 1.8GHz to perform as well in day to day usage.)

Most people overclock for a smoother/snappier experience. I notice that roughly 20% increase in scrolling/tabbing around. Also you can think of it like this:
1.4ghz will finish tasks faster then 1.2, that way taking less battery. You could also undervolt that 1.4 to 1.2 (1275mV), so your finishing tasks quicker while draining no more then stock.
I switch between 1.4 and 1.0 every other day it seems. 2 months later, still looking for the right one for me. 1.6 should only be for benchmarking imo, epeen.

It's not that simple.
There are dozens of bottlenecks in these devices (and any other computer), and 9 times out of 10, it's NOT the processor. Persistant storage, RAM, bus speeds, etc - all those things will ensure that a 10% bump in processor speed will NOT give you a 10% decrease in run time for a given typical application. In many cases, you'll see no speed increase at all, as it takes the same amount of time to flush to persistant storage no matter how fast the write cache fills.
I'm not suggesting that a person shouldn't O/C, but don't be surprised when going from 1200MHz to 1400MHz makes no visible difference other than the battery draining slightly quicker.
I know someone is going to respond that the processor will bump back down to a slower speed and therefore it runs at the higher speed for less time, etc. However, unless you have the governor set to poll for usage so often that the governer is driving your clocks up to max, it's not going to poll often enough to make much (if any) difference.
Think of it this way: We both own a mustang, but mine is a V6 at 220HP and yours is a V8 at 300HP. In theory, yours can accel faster and maintain a higher top speed. In reality, neither one of us can go faster than the car in front of us (but you'll burn more gas doing it.) (Of course, you'll have more fun in yours.)
I hope this helps with a very common misconception.
Take care

Very true. Also I am guessing in gaming, that OC will drain your battery quite well.
Consider I mostly do Web browsing on my phone (I need a tablet), 1.4 is a much better browser experience imo. Worth the 100mV.

While for now Overclocking is mainly just done for fun im hoping that closer to my upgrade time that i will be overclocking for more actical reasons. That is the way it was for my Captivate. I enjoy trying to push my hardware to its limits. Ive gotten my GSII so far to a stable 1700mhz but i think i can squeak out a little more speed especially with the gpu down clocked a little. I run it at 1400MHZ Though with the gpu forced at 267mhz.
Hey fellow XDAers
I'm currently running LeeDroids awesome GSM Rom, with his Kernel and a lot of others the stock speeds are 384mhz - 1.51ghz (using LagFree governor).
I'm just wondering is there any point of having it boosted from 1.18ghz to 1.51ghz or is it just overkill? I can see the Sense UI is slightly smoother, but I'm not really sure how the battery life is affected by the OC.
If I wanted to save battery life, would it be best to reduce it back to 1.18ghz or use a different governor (and what one?)
Thanks in advance,
Louis

Yes i read overclocking do take a toll on ur battery just like an engine more horsepower/cylinder more gas lol if u really need the extra speed try juce defender or something to help save you your battery while over clocking. Hope this helps
I keep mine at 1.2ghz max as it is fast enough like that, and makes the battery last longer.
Yeah point off overclocking is that we don't need buy an new device to get some extra speed. But I think on 1.2 it runs fine to.
No sorry, I think I worded that incorrectly. I mean with custom Kernels they usually are 1.51ghz by default.

If you want insane speed is what you gain tho you don't gain better battery life More speed the less life... . Both cores running all the time will eat it up.
If you push it too high you can burn it up.. Depends on what you want outta things...
Well the second core isn't so active as far as I know. It has been more designed to jump in when needed.
But reason most custom roms include an overclock off 1.51Ghz is because the cpu was designed for it, HTC just under clocked it, but in the HTC Sensation XE they not underclocked it.

Ah, I see now. I get what you're saying now. Overclocking is good, but becomes detrimental when the freq starts sucking the life out the battery.
Aren't we underclocked from the jump. I though Chad Goodman said the actual processor speed is 1.5 by default. Per Qualcomm specs at least.

In short, yes.
OC'ing makes your phone much faster and, also helps out with benchmarks. However, battery saving is not an issue either. Most CPU control apps will allow you to set a different frequency when the phone is closed so it saves batter. For example, I'm on zr3d right now and my normal profile is 1.7x ghz. When the screen is off, it scales conservatively from 192 to 540 mhz. Gives better performance and better battery.

OC beyond Quallcoms spec 1.53ghz is pointless and good for nothing but killing your battery. There are a great many here who gush over high benchmarks but that means absolutely nothing in "real world" performance no matter how much they tell themselves that it does. Just sayin....

But for the average use (browsing, video streaming, bit of gaming, messaging) what should I set as my max OC as? And what is the best governor for battery + performance.

Nope.jpeg. I was playing canabalt the other day at 1.5X ghz. It was the tiniest bit choppy so I upclocked to 1.7. Perfect performance and, also real world performance I believe(actually it's a game so its not real life).
Best settings I'd say would be 1.5 ghz on interactive/intellianthrax guvner while screenon and .5 or .3 ghz conservative/powersave while screen off. Or, for heavy stuff, go all the way up to 1.7/1.8 ghz.

It doesn't. At least from my understanding. In fact as I understand it running at higher clock speeds would decrease your battery life no? I usually under clock, so...

The theory is that overclocking allows you to complete processes quicker, which in turn allows the processor to go back to a idle/deep sleep faster. In practice it doesn't really work that way though.

Undervolting rarely makes a difference on mobile SoC's, but on the desktop/laptop CPUs you can really save a ton of power with undervolting and underclocking.

The article says its not the actual overclocking that is saving battery life. When you put SetCPU on your phone not only can you overlock but you can underclock and set different voltages. I'm not 100% sure how the voltages play into it but you can set the processor to run at really low speeds during certain acts ei. when the screen is off, or any other time you don't necessarily need alot of power. That's and I changed all the voltages (I got them from a post where the guy knew what he was doing and tested them). I get almost 2 days moderate browsing, apps and text. If I talk alot or use my hotspot I only get 1.5 days. It is a little time consuming to get everything just right but when you do you really see it.

This isn't a SetCpu feature there are other programs that can do this as well. It just so happens SetCpu has it built into the program. I bought SetCpu back in my Atrix days and loved it so it does work great for a simple tuning program.

I'm running a kernerl and a custom ROM that allows me to underclock and overclock.
I tried it out both ways and the battery lasted for almost the same amount as on the stock option. As I tend to play games a lot on my phone, the underclocking ran into some issues with stuttering and sometimes force close of a couple of games.
Personally, I've never been a big fan of either .
