@soulzero, care to share your settings with that benchmark score?like cpu settings etc...
i only got 18367 with stock cpu settings on vanir rom.

My best is 26777. I'm on latest Mahdi, using Demetris kernel and the optimized dalvik. I actually tested several times on Mahdi, then flashed the optimized dalvik and tested. Got a good increase. Then flashed Demetris' kernal and tested. Again an increase. Averaged 23847 on Mahdi, 25647 with optimized dalvik, and the 26766 after the kernal.

I usually use the optimised files as they have been the highest scoring for me, though I check with quadrant.
That score I posted above was running Art as I changed over last night to see how it runs and ran antututututu out of curiosity.
When I get a chance I'll switch to optimised dalvik and bionic and do a few runs.

24761 run once, on the V510 out of the box using the sleekai kernel. Nothing else is optimized on my device. I really don't know if the stock kernel would be any different. Maybe. They still ramp up to maximum cycles during the test. Stock default is Performance and CFQ, whereas sleekai default is On-demand and deadline. I do think the deadline is better at handling scheduler requests. I get a smoother scroll action I attribute to the deadline scheduler. Also a way better battery life.
I don't really think benchmarking is a good way of judging the performance of the device within a 5000 point range, but thats just my opinion, and may be wrong. If your cpu heats up too much during the test, your device will slow it down.
Edit* Newest Antutu Benchmark on the 510 out of the box using the sleekai2 kernel is 27052
As a side note, The gamma problem has been resolved entirely using this kernel. No more need for Trickster.

As I said in another thread , the secret sauce is this http://forum.xda-developers.com/nexus-4/general/4-4-4-4-x-qualcomm-optimized-dalvik-t2546120
I'm guessing the v510 doesn't need these libraries for its high score but we do.
It's all moot for me. I'm currently using ART, which scores in between the two when benching, but in reality I don't notice any difference between the three approaches in daily use.

This is how I tested.
I installed Antutututu and quadrant.
I ran both several times to get base results.
Then I flashed the dalvik file and wiped dalvik and cache and ran both benching tests several more times and noted those results.
Then I reflashed my backup and right after flashed the Bionic file only.
I wiped cache and dalvik again, booted up and re-ran benches.
After noting those results I flashed the dalvik, so I now had both flashed. I wiped dalvik and cache again and ran more benches.
I've done this on cm11 and mahdi.
All the best rich
Just an addendum,
Whilst I have ran these tests, it has been for a bit of fun,
As I said in the Antutututututututututu thread, I'm currently running Mahdi and ART.
It scores around 4k less in antutu, but in practice I see no change in behaviour In my gpad.
I guess the gpad has enough power that the extra oomph that these files are supposed to deliver, is just a small ripple in real world use. Even if it's 4k in antutu.

Yeah, tried ART as well but didn't notice any sort of improvement. What i'm mostly after is solving the "thing" that makes UI animations a bit less then 60 FPS. It's more like its 30-60 FPS and one can definitely notice a drop here and there. My old Nexus 7 (2012) is more consistent in that regard and it's UI (stock, unrooted) actually responds faster to touch events which is a bit odd due to its old Tegra 3 processor and non-modded/rooted OS.

Ran a bunch of benchmarks. All in all it's way too inconclusive since the difference in average pretty much is in the margin for error (the highest average only differ around 1000 points from the lowest average).
I don't seem to be able to go beyond an average of 24.348 so it's odd to see some of you post scores that is almost 3000 points higher then that.

I would say your governor might be the cause : you are using OnDemand, have you tried swithching to Interactive ? In my experience, it would solve most of my stuttering launcher issues.
If you want better scores, you might wanna try Performance, but I wouldn't recommend it for everyday use.
I wrote a long reply last night and lost it so today I will do it again but a bit at a time
Ok as already mentioned I also prefer to use interactive and if the kernel allows then it's always interactive /row.
If row is not allowed by the kernel then I use deadline.
I would like to suggest that it's probably not just one thing that needs to be done, but a number of small tweaks that accumulate to achieve a better bench score.
Now some of these tweaks are only for benching whilst others will give you a zippier feeling tablet.
This would be a typical setup for me to bench and I'll point out which I used day to day to speed up my old N7.
First flash the dalvik and Bionic files (obviously not tried on the tegra N7)
After booting up go to developer settings and uncheck the three animation settings, then scroll down and check force gpu rendering. (this mod is good for daily use for a bit more zip, I used this on my N7 2012.
Next go into whatever app you use to adjust cpu.
Adjust the min and the max cpu frequency to 1.728 ghz (you may get reboots with the minimum set at this, so just dial it back slightly or increase the voltage value for 1.728 ghz)*this is most definitely not for day to day use *
Next go to the gpu governer and change the setting from ondemand to performance (I believe this has quite an impact and I reckon that it's a good one to try for day to day use)
It's worth spending a bit of time having a play with sd read ahead value.
I set mine to 2048, more from habit than any testing on the gpad. It is definitely the way to go on my phone but ymmv. This can be used all the time if you see a worthwhile difference.
To a degree I too stop some apps before benching but in the past I noticed if not careful this can be detrimental to antutu.
I use clean master for this as you can go into settings and modify the ignore list.
I think that is just about all that I do. I will update this if I think of something I missed.

Yes, with interactive i didn't notice better performance. In previous tests interactive actually always scored lower.
Sure - the performance governor can get better scores, but i'm not just after scores and ondemand or interactive should manage to score almost equal to performance when benching (within a 1000 point error of margin at least).

smartass governor - is based on the concept of the interactive governor.
I have always agreed that in theory the way interactive works - by taking over the idle loop - is very attractive. I have never managed to tweak it so it would behave decently in real life. Smartass is a complete rewrite of the code plus more. I think its a success. Performance is on par with the "old" minmax and I think smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies.
Smartass will also cap the max frequency when sleeping to 352Mhz (or if your min frequency is higher than 352 - why?! - it will cap it to your min frequency). Lets take for example the 528/176 kernel, it will sleep at 352/176. No need for sleep profiles any more!
i googled it lol, seems like its a bit more responsive then interactive, and it ramps down quickly too. could give some battery savings
What ROM's will this work with?
keeps cpu at/above 768mhz, will not go below until you switch off smartass gov.
liking the "sleep" enhancement, but seems like it should let the processor scale on down to 245 when idle with screen on
I'm running this with CM7 Nightly #16 and it's running really well. I'm getting a little more battery consumption than I do with zinx's kernel, but that could just be because I've only been using the kernel for around 2-3 hours. It may need a little more time to settle? I'm not sure, but it is definitely snappier! If it does scale down the cpu during screen off, you can't tell at all! It doesn't have any lag when unlocking like setting profiles usually does. So I'm really stoked about this kernel! Great work as always Dumfuq! This will be my new kernel for at least a few days to give it more of a chance.
PS: I'm only getting around 29 on linpack at 1.017 GHz, where as with zinx's I was getting 38's. Smartbench scores are at 1320's for productivity and 1869 for gaming. So those both beat out zinx's kernel. Just wanted to put those out there so people have some kind of a comparison point.
posted a v2. The difference is frequencies are changed to match glacier frequencies instead of hero's.
The only noticable difference here is that when the screen is off the frequency scales between 245 and 368 instead of being stuck at 245.

I've had great battery life with this kernel so far.
I have recently rooted my dhd and currently running CM7. Using the cpu setting within the performance menu I am wondering what peoples thoughts are on a noticeable but safe increase of cpu speed. its set as 1017MHz which i believe is default. I am told I can run anything up to 1500 safely. can anyone confirm this and also tell me what kind of result (performance and battery life) i should expect.
thanks
Well, I use Android Revolution HD (a sense rom, meaning heavy UI!) and i overclock to about 1.3GHz. In terms of battery life when it's awake, it seems a drain a teeny bit more readily, but I've never had a freeze on sense (quite rare)
On stock it underclocks to let the processor max at around 400MHz when the screens off, so that helps to really save a lot of battery on standby. On CM, I'd expect it'd feel more or less the same in terms of performance after you hit 1.2/1.3GHz

The CPU is managed by the ROM itself. You can tweak it yourself by using setCPU (or similar), but I can advise you not to. Can't help you with the governors buddy, since I dunno what it is

Lucky you picked a linuxhead!
The system itself has a daemon (background process built into the system) that handles overclocking. It's all explained on the page and also on this thread:
http://forum.xda-developers.com/showpost.php?p=14638641&postcount=34279
You can use another app (like SetCPU) but the daemon usually handles screen off's quicker. The governors basically determine how the processor frequency is changed. I'll explain the common ones:
Performance - Runs at highest speed, so if you have a range of 200 to 1.3G, it'll stay at 1.3G all the time, not usually the best
Ondemand - The universal default for phone overclocking, it only changes the speed up after a certain percentage of the CPU is used, and it switches on the fly, so if the CPU is used too much at 400MHz, it'll ramp it up to maybe 600 or 800, and if it's still overused, it'll put it up to maybe 1 or 1.2G
Conservative - This is like ondemand, except it makes the changes more gradual. It can give noticable lags in the foreground at times, so this is mainly used when the phone is asleep (screen off)
Smartass - This governor is like ondemand, except it'll less readily switch frequencies to higher values when it detects the screen off. This isn't really used because the overclocking daemons take into account the phone being awake or not
Basically, there isn't really a need to change governors, only really frequencies if anything. The thread, however, does tell you how to change governors.
Im using latest LeeDroid GB 3.2.1 and to be honest with the work he's done with the Kernal (3.1.8BFS) I have found that the ROM is a lot MORE responsive without me overclocking the CPU.
Im not really sure how it all works, but I guess doing this on different ROMS has its own different out comes.
overclocking has me confused too, is there really that much of a benefit in it? how much will i gain from it?

There is a benefit when you use certain apps, or even sense itself. For example, I've never had sense ui freeze, or go slow. The under clocking helps to improve the rubbish battery life when your phone is asleep.
In terms of measuring the gain, I have no idea. Really, I'd think you could use a process heavy app, or benchmarking app and see.
There's also loads of guides on overclocking to help out! (that's how I got the hang of it! )

Sent from my Nocturnal 4G using xda premium
Each Evo is different. Some of them can't handle that high overclock, or can't be undervolted very low. Each one is different, each has its limits.
I don't understand the big deal with overclocking. It burns your battery faster. I personally underclock, with little to no lag and is good enough for my casual gaming needs
Mine doesn't like a clock much at all. I can get about 1.1 before it starts locking up but even then it hangs a lot. I honestly don't see a difference from 1.0 to 1.2. Get a decent rom, good kernel and try out the v6 script an I almost guarantee you will like that better.

Overclocking is overrated. If you need to overclock for every day usage, then something is wrong - at least in my opinion. Resource intensive gaming is different, but you shouldn't need to overclock for browsing, texting, casual games, etc.
Try out the V6 Supercharger script. I'm not currently using it, but have in the past and it seemed to make my phone more snappy. A lot of people swear by it and it's a great script, definitely worth a shot. There are other things you can do to speed up your phone without overclocking. I'd try other options first since overclocking will chew through your battery. Increase the dalvik vm heap size, there are plenty of free apps on the market to help with this task. Uninstall apps you don't use, I'll bet that you never use some of the apps on your phone. Back them up with Titanium Backup and you can restore them if you ever need them again.
In case you didn't already know, the Evo can't overclock past 1.2, I'm not 100% sure why - it has something to do with the processor.

I never oc over 1075 and only when plugged in if i play a game I need to oc.for I just activate my charging profile and plug up and play 1.2 ghz is a good chance of doing serious.damage as these older scorpion processors get very very hot at that clock speed so they lock up to try and protect themselves from heat damage or they shut down the phone 1075 is as high as you should need to go for any games the evo can handle on the subpar gpu

I'm pretty sure viperMOD is more for undervolting than overclocking, which are not suppose to be combined together. I am running vipermod with max voltages - 50. Other nite was playing snes9x and was getting some lag with a game so I bumped max CPU up to 1.2. Phone went into a bootloop and had to superwipe and reflash everything. Don't know if its b/c vipermod + 1.2 CPU or just bumping up CPU. Didn't try it again.

You can overclock and undervolt together just fine. You just need to ensure that every frequency has a high enough voltage to run the processor at that step. My Evo is overclocked and undervolted just fine, although IIRC I can only push it up to 1.1 GHz . My tablet is 1ghz to 1.6ghz and is undervolted as well, though.
merge rls 2.0, iron monkey, Droid overclock because of the profiles options. I set up four profiles including one for temp. sometimes i'm underclocking and sometimes overclocking but only up to 1.19 to prevent freeze and boot loops. Only downside is right at open Droid overclock needs su permission but that is my choice since profile changes at open.
Very snappy afterwards.

When I had the 4G, I was never able to go above 1118, or somewhere around that. It would have freezing issues.
On my evo shift, I was able to do 1.7 gHz (compared to stock 800 mhz) ok. 1.6 pretty reliabily, and I could run 1.5 all day long. Some guys could do 1.9. It just depends on the phone.
Actually overclocking and undervolting is counter-productive. What you should do, is read carhaulers and ropodopes guide over at vaelepak. Its give some good useful info about how to set up a good aosp rom. I'm underclocked, undervolted, and still getting 1400+ benchmarks. Check it out bro. You'll love the results.

What? Overclocking and undervolting are two completely different things, and they aren't mutually exclusive. Unless you can provide a good reason as to why it's counter productive to do both, I don't buy that at all. Just checked my phone, my overclock requires an extra 25 mV for all three steps I've overclocked. 25mV isnt much, and it certainly isn't going to kill my battery that much faster.
Besides, the only time the CPU is going to be entering these high power modes is when it needs to do work, and it's better to do work as fast as possible to go back to sleep. Would you rather wake up, do a mundane task for 5 minutes, then go back to sleep or wake up, do a task at 2x the speed while only consuming 30-50% more energy, then going back to sleep after only 2.5 minutes?
HUGI is real.

First let me say I don't use viper mod or any voltage controlling mod.
On sense 3.0 roms such as mikg I over clock to 1152 and set the minimum to 384 and its smooth as butter. No problem and battery lasts all day.
On aosp however such as decks (I'm on it now) I underclock to 499 and leave the min at 254. Smooth as always and battery lasts forever.
Anything past 1152 is going to cause problems (at least in my experience) also the rom/kernel can effect how much you can overclock.

What? Overclocking and undervolting are two completely different things, and they aren't mutually exclusive. Unless you can provide a good reason as to why it's counter productive to do both, I don't buy that at all.

Its counter productive because it is giving less to something that needs more. (Don't take this post as me trying to be a ****. Just voicing how someone explained it to me a while ago)
Think of this as cars.
Lets say you have a nice fancy v8 mustang. Stock, everything is well, balanced.
If you start adding parts and get it pushing out 1000 horsepower (overclock) your most likely gonna need more feul (voltage) or at least stock amount flowing into the engine just to keep it running.
Now lets say you got that same 1000 horsepower gas destroying mustang and you start to lower the amount of gas flowing into the engine (undervolt (done in vipermod)) cylinders (CPU) wont get enough gas, it wont work, and your stuck going no where.
So if that made sense (did to me) then you can see why they are counter productive. Unless your using vipermod to overvolt (which idk if you can since I don't use it) then you can disregard this whole post

Your car analogy is completely irrelevant. You can look up the exact voltages that the CPU runs on at every frequency, *even when overclocking*. Overclocking an Evo 1ghz to 1.2ghz takes maybe a 5% bump in voltage, and that 5% extra power is only going to be used *when the CPU is running at max speed* (which is only when there is a lot of work to do), and even then, it's *still better to let the CPU run at max speed with a tiny bit more power consumption than to cap the CPU at a slower speed and make it work for even longer*. Intel calls it HUGI, Hurry Up and Get Idle.
I know what I'm talking about, and I wish people would stop trying to argue with me based off of second hand speculation. I do this for a living, after all. There is absolutely nothing wrong with overclocking and undervolting, and it's the best way to get the most battery life *and* performance out of your phone, period.

Hmm, *interesting*. I believe the best answer to the OP was covered rather well earlier. It's all about your rom/kernel/hardware combination. With all the variables to consider as relevant, your best bet is to experiment and find what works for your device. Don't check set on boot untill you are confident the set-up is stable. Higher is not always better with overclocking. My device runs blazingly well underclocked @768max. Gets insanely great battery @499max. However my quadrants are better @ 1036 than at 1190.
Great thing about android is you can experiment and learn through trial and error.

Can anybody post the maximum undervolting settings for galaxy w?
Currently i have all settings -100mv. How much further can i go? How can i identify if I've overdone it?
Current Kernel: [Kernel][ICS] Arco+ V1.3's kernel & HurtSkyV2's kernel 29/3/2013
1.4 Ghz run stable down to 1.075 V for me.
With 1.050 V, is freezes after some seconds of the AnTuTu stability test.
I guess that stock voltage for 1.4 Ghz is 1.250 V, as it can be seen in arcos repo.
Nice under voltage
Yes, i am satisfied with the result.
Guess that 1.4 Ghz might be some kind of sweet spot, as my lowest voltage with 1.0 Ghz is something about 0.925 V.
Depends on the scenario, but the energy-per-cpu-cycle-ratio might be better with 1.4 Ghz after all, plus full calculation-thrust
Also had it running at 1.8 Ghz, and at one point with 2 Ghz, but i do not remmeber the voltages exactly.
Might have been something around 1.275 V for thw 1.8 Ghz one, also a good result.
By the way, there are quite big differences:
My Intel Core 2 Duo T6500 runs at its full 2.1 Ghz with the lowest possible voltage, 0.9250V, normal is 1.150V
On the other side, i had a desktop E6600, which needed much additional voltage for little OC, and was also bad for UV.
(seems as it was an exception, as they were known for excellent oc capabilities).
Sorry for OT

Thanked for sharing your numbers with everyone =)! may i know how can i safely experiment with undervolting? like what do i do to make sure there will be no hard-breaking or equivalent events from happening? and also how do i know i should stop and choose the voltage 1 level higher than my current value (i.e. when is the value too extreme that it could be bad for my phone)? Thank you in advance!
I shared my voltage in hadidjapri's CM9 kernel thread. Let me dig up the link for you...

As you can see in the table I've posted there, the undervolting varies according to frequency. I've undervolted by 175 on 1 GHz, and perhaps can still go 25 lower.

My suggestion is to use the numbers in the table I've posted. Use the phone for 2-3 days and see if it becomes wonky (random reboots, hangs, etc). Then try reducing the voltages to the "extreme undervolt" values in the graph I attached to that posting. Then lower the voltage for the 'sleep' frequencies first (369 and less), and slowly work your way to your maxfreq.

For me it´s a bit different. At the upper frequencies (1000-1400MHz) I´m at the extreme UV voltages. But for the lower frequencies I need to be +25mV above the extreme UV settings.
So there is noone who can tell what the sweet spots for all the frequencies are. Each CPU is different and everyone has to find out his sweet spots himself.
For stability tests there are even some apps at the play store, though I found the facebook app to be the best stability test app at all. Where all the stability tests passed the facebook app crashed if I undervolted a little bit to much.

alright i'm trying with the extreme UV settings now (with +25mV for freq <1000mhz, will reduce later if stable) but i'm not sure if its the new Queen Anne's Revenge v2.3 rom, hurtsky's 2.1 kernel, or the usage of smartassH3 + sio that is causing my phone to feel less responsive (like takes 2-3x longer time to launch apps like whatsapp, boat browser, also launching incredicontrol twice in a row crashes incredicontrol lol). Is this a sign that I am undervolting too much? because I've tried raising all values by up to 50 from the extreme UV but doesn't really help. also tried changing smartassH3 to smartassv2 (my previous governor)

Undervolting doesn't affect performance, at least not directly.
What it affects are power consumption (i.e., battery life) and stability; some components within don't perform reliably with too low a voltage, and may internally reset themselves. This causes the kernel to go into panic (because the state in the kernel no longer matches the state of the hardware), and as a result, crashes.

ok. i used CWM to clear cache and dalvik cache, which forced the rom to "upgrade" again. The lag is significantly less noticable =)! Perhaps when upgrading rom (non-pristine), it is better to clear cahces
how sorry i'm a newbie here may i ask how to undervolt (or a link)? i've been having problem with battery life so perhaps this will prolong it further..
Download incredicontrol and u can use that app to set voltages. Follow graph given by pepo . Make sure u do not set as boot first. Test for like a day and if no phone hanging or restart then u can set as boot
Freq-voltage(mV)
122-775
245-775
368-850
768-900
806-950
1 02-975
1,11-1000
1,2-1025
1,3-1050
1,4-1100
1,5-1150
1,6-1200
1,7-1250

I use these for my daily use, and it seems no problem at all.

Hi guys,
I understand that some heat when running resource intensive applications and games is to be expected but I believe I've passed into the danger zone, so to speak. When playing XCOM my CPU temperature quickly exceeds 80°C. From my googling on the matter I have come to assume that a temperature as high as 80°C is dangerous for the hardware of the device, but I have had trouble finding upper threshold limits for the model itself.
I guess my questions are as follows:
1) How damaging would running the CPU at 80°C for an extended duration (1hr +) be?
2) What would you consider the max acceptable CPU temperature to be?
3) Assuming it is as bad as thought, what are my options to reduce the CPU temperature, short of avoiding the problem applications? Underclocking seems to be a common suggestion, but I get the feeling that XCOM, or similarly taxing applications, may just fail to run or become incredible sluggish under such constraints.
My device is rooted and running Lean Kernel v2.4 along with the w03Slim ROM. Found here: http://forum.xda-developers.com/showthread.php?t=2638116
I've done similar test runs in the Temasek kernel with the recommended configurations through Trickster Mod and there is no difference, the CPU still exceeds 80°C when playing XCOM. After a week or so of googling, searching the forums, and digging through device manuals I feel like I'm spinning my wheels.
Any insight or advice you all might have is greatly appreciated.
Solved!

You can try a custom kernel, i would recommend you BioShock kernel, with conservativex, max freq 2.2 ghz and undervolt 25 mV... No more over warming for me, great performance and battery life

Agree with this post, conservativex is a great governor to keep your cpu in check and not over throttle itself, also check out my thread I made here awhile back and apply the 8th post down. It really helped keep the temp down on my phone when playing graphically intensive games like dead trigger 2,riptide gp2 etc. Also if you have trickster mod or faux clock(really recommended) you can scale down your max frequency, that should really help keep it cooler and you won't see much of a performance drop (if any) while gaming or heavily using your phone.
