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.

I have run roms with 5.1 MFLOPS and now am running a rom that gets 3. I can honestly say I see no difference.

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.
Hi there. Why am i getting only about 1000 quadrant score, while everyone getting somewhat like 1500 on the same roms?
Do i have a different hardware or what?
Different roms will get you different results. Gingerbread roms appear to run around 1000+ while Froyo roms run closer to 1300+. Run it a few times and you should get a better score. Quadrant doesn't really matter too much though. What's important is how the phone feels for you not what a graphic tells you.
Thanks for reply, but the problem is that i'm having different results than people on the same rom.
And does the quadrant score affects on how smooth the games are running?
Do you have a lot of apps installed on your internal memory? The "cleaner" the phone is the more optimized. Junk apps will definitely decrease performance. As for running games, quadrant doesn't affect how smooth your game is running but does show performance measures that could be related to efficiencies of your phone. Theoretically, the higher the quadrant score the better your phone will be at running your games.
What file system are you using...quadrant takes your free space for apps in score consideration..
If your using data2sd and have 2gb for internal(ext2,3,4) then quadrant is going to show a better score than those on rfs.

Oh ok..
But my point was having lesser apps and having more. Internal space will increase the quadrant..
Sent from my GT-I5800 using Tapatalk
Which rom(s) are you using?
FYI - Fresh install of 2.1 will only get you around 500. JIT enabled gets you around 600+, removing additional junk apps will get you 700+. 2.2 Roms will get you over 1000+ easily. Z's Froyo beta 3 got me around 1500+. Others including Gingerbread hover around 900-1300.
I have tried CM7.0.3 J020c and trip's froyo.
In both roms my quadrant is about 1000, but for other people trip's rom giving them about 1400-1500.
I am on wolfbreaks rom..(as per my signature)
The only other thing i do is move all aps to the sd card that can be moved and leave the ones with widgets on my internal memory.
I average about 1450 to 1550 with my best score of 1609.
Run it a few times as well..
On J's rom I run around 900-1200. Never tried running quadrant on Trip's froyo but on his Arc rom I get around 1000-1250. Again, quadrant isn't that big of a deal. Your games will run fine on your phone. Remember, try to have more free internal memory and get rid of junk apps you don't need.
on wolfbreaks rom. i move all apps to the sd card (except widgets)
1300 - 1400
Okay, thank you, guys, quadrant isn't important, but it's kinda wierd that i'm having lower stats than other people.

Its not weird at all. Everyone has different apps and settings which affect benchmarks differently. Higher Quadrant scores don't neccessarily translate to better performance either so why does it matter. Also in order to get reliable scores in quadrant you need to run it twice in a row as the OS will kill apps and adjust as the test runs the first time and the second test is always higher and more consistent.

If I (or anyone for that matter!) help you, dont be afraid to press THANKS!
I stumbled upon these apps by dumb luck and decided to post this for anyone that doesn't know they exist. The dev is Chinese I am guessing based on a lot of his apps being in Chinese. He soes have these 3 apps in full English though and I am glad he does! For anyone that is looking for a SetCPU alternative, look no further. I will be the first to admit that I am not crazy about SetCPU. The app and I don't get along because of stability issues. CPU Master can do everything SetCPU can do but with better stability. I have been using it on both of my Vibrants. I have one Vibrant with the MIUI Rom (1.7.29) with the Bali 1.1.1 kernel and the other Vibrant is running CM7 Trigger Redux #17 with the Bali 1.1.1 kernel. I have had ZERO issues with the phones. Set on boot work flawlessly and overclocking is a breeze. The will give you every scaler that is included with the kernel you are running along with whatever overclock speed is set in the kernel. The Bali kernel supports up to 1.4Ghz and thats what the slider is maxed at. I loaded the Glitch kernel that supports 1.7Ghz overclock to see if the slider adjusts to that speed and as expected, I got 1.7. The only difference between the Free version and the paid version is that you can set and edit profiles in the paid version. For 1.99, its well worth the investment!
The Benchmark app ties directly into CPU Master. It tests everything that Quadrant Advanced (paid version) does PLUS it tests the speed of your SD cards! All of this and it's Free. If you are playing with overclocking speeds on your phone to see where the threshold is on your device, this benchmark will tell you. Through its rigorous testing you will see right away if your phones CPU can handle the speed you are testing. If you lock up during the test, its time to slow it down! On my MIUI Vibrant, I can only go up to 1.3Ghz and beyond that it freaks out. On my CM7 Trigger Vibrant, I can run 1.4Ghz with no problems.
Smart Profiles Free is a great app for people who spend part of their day in places where being quite is important. You can create all kinds of different profiles throughout your day to keep your phone running like the way YOU want it and not worry about turing on and off features. Just make your profiles and you are done! For example, from Monday to Friday I am at work 8 - 4:30 and I want my phone on Vibrate only. During those times I also want my WiFi on to use the company's internet and not my data plan and I also want my GPS off. As you can see you have A LOT of control of the various functions of your phone!
These apps are definitely worth the time to take a look at and try out. For any end user that wants even more control of their phone, they are certainly a fantastic addition!!

Excellent over / underclocking utility!
Yes, sure Antutu CPU Master is really a very good and powerful utility. I bought the pro version and it is worth the money. I am using it in my Samsung Infuse 4G, this allow the device to be underclocked till 100 MHz and overclock up to 1800 MHz, of course with the required Kernel and root access. It can be configured by the readymade profiles that can automatically change the clock settings based on conditions.
The widget which is just two column wide and 1 row height shows CPU Speed, Battery Status and Temperature.It has profiles, default, Charging, Screen off, In Call, Low battery, Temperature over-heat.
For stable clock setting set the minimum to 800 MHz as below this the device goes unresponsive particularly when the screen is off. I am using the range between 800 - 1800 and so far no issues, and it works great!
As mentioned, the benchmark, CPU setting and profile are great features of Antutu collection of software. Thanks to them!
Hey what would cause my java scores to drop using cf bench..I'm not sure what its measuring but it seems to have cut in half for no reason ..I think its at 1800 when it was like 4k before ..this isower than stock
Btw I'm on viper and helicopters #1 kernel ..with this same combo I was getting an overall score of 8k so I'm not sure what has happened ..and its not just the score I can feel it using the phone.
You got an app that is a cpu hog maybe, it could be a number of things. Reboot your phone and then clear out all your tasks using an app like Fast Reboot, then run a quadrant. Also an app like system monitor can show you what apps are eating up cpu and battery. Hope this helps.
I just noticed I got the same set up as you as far as kernel and ROM, its got to be an app in the background cause I get no lag whatsoever and im only over clocked at 1.5 with the screen on.
Edit again: maybe your over clocked too much, I read that pushing it too high can create lag also and be counter productive. With me 1.5/on demand seems to be the "sweet spot" for battery/performance.

Thanks for the reply..let me explain exactly what happened.. I had the setup I told you for a few days and I was using setcpu to Oc..at that time I.was getting about 8 k cf bench score and the phone was fast besides the fact that setcpu was acting funny..then I set up the Oc daemon and set it to 1.8 just like I had it for setcpu. I really liked the daemon bc the phone was super fast..I then flashed an icon pack..at this point i was still getting high scores..I then tried flashing a theme and after that is.when my scores dropped significantly and i felt a little slowdown..so I.flashed back to just the ROM and kernel with no theme thinking that the theme was the issue. Unfortunately I'm getting the same low scores. The java score is very very low. I dont have many apps and i didn't even re install any apps besides the cf bench when I re benched it
Try viruses superwipe, that might help.
Will do
..should you wipe when flashing another kernel
If its just the kernel just wipe the cache and dalvik cache.
I did superwipe and my java score went up 1000 points..I'm at around
6500 ..right on par with the gs2..so its better but not as good as before..but I'm happy bc everything feels good..since your running same setup as me if u can do a cf bench and let me know what you score is appreciate it ..thanks for your help
So I overclocked my GSII to 1.6Ghz, and ran benchmarks and it was blazing fast. So what's the point of overclocking other than running benchmarks? I'd rather not have my processor running at 1.6Ghz all the time and draining battery power. I actually prefer underclocking to save power. So my question is - how else can I benefit from overclocking my device?
yo whyd you put this in the dev section? get flame suit on brotha.

Well its obviously to have your device performance better. Honestly it's not really practical to run higher than 1.2 ghz though.

But in what ways other than benchmarks? Am I really going to notice a difference if I kick it up to 1.4 or 1.6Ghz when browsing the web or playing Angry birds or something?
where is the download link and what does it do?
Some serious development going on here.. [\sarcasm\]
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
But dude.. Googling the benefits of OC could have giving you an answer ..and FASTER. Lol

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.
another reason to overclock would be bragging rights

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.)
One reason could be... Because we can!

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.
