You might have already figured out that HD2 can be overclocked as high as 1.5 GHz on its powerful Qualcomm SnapDragon Processor. Many people run their devices on default clock speed, but there are few of us who overclock their devices to get max out of it. So i have started this thread to know what your max clock speed is and what governer are you using. Post replies below. Also, don't forget to mention your Phone's Temperature if available.
Mine: 1.2 GHz On SmartAss Governer , Temperature Usually Around 95F

1305MHz using interactive, temp alway @ 28°C even when phone get hot?? tho alway careful to let it cool down when it feels too hot.
I have underclocked ... to 720Mhz (interactive)
Performance is okay and saves battery live
Temperature is about 28 celcius.
1267, 768 when battery less than 30%, 422 when screen is off
On-demand w/screen on, conservative when <30% and screen off
Not great on battery, but good performance an no wake lag
CPU Load jump or whatever it is, set to 30%

Sticks with no overclock
using a rom which is fast enough and saves battery life, Dont see a point that needed to overclock CPU
Undervolted to 576mhz, for better battery life.
Runs smooth enough for all apps, including navigation and games
No overclock for me, don't need it, phone is fast enough as it is.
Clock speed: 998mhz (default), governor: ondemand, temp: n/a
Good enough for me sweet onough on may battery.
P.s. there seems to be no difference(performance wise) between rafpigna kernel oc'd @1.5ghz and tytung kernel oc'd @1.2ghz, when testing on linpack and/or other smarbench tools
which of the recent governors gives best performance?
lazy, interactive, smartassv2?
Thanks guys
I just use Ondemand. I've tried others but I always end going back to it.
I've heard interactive is good for performance. I was under the impression that lazy and smartass were more geared towards battery saving.

I use lazy or ondemand typically.
Follow the leader @corythug
for performance, ondemand with a sampling rate of 15000 and up threshold of 98.

simms, I am assuming this will drain battery faster as the default sampling rate is 40000. Am I correct?
Sampling Rate – An interval (in microseconds) at which the governor will poll for updates. When this happens, the governor will decide whether to scale the CPU up or down.
Up Threshold – Defines a percentage from 1% to 100%. When the CPU load reaches this point, the governor will scale the CPU up.
i like smartassV2 1200 / 100

no. itll actually be a little better on battery, a little more efficient than the default. and itll give the ui a little speed boost.
Isn't interactive supposed to be a 'better OnDemand'
I'm thinking it's the opposite, that on demand was an improved interactive, but I could be wrong. I really don't notice much difference between any of them. On lazy and smartassv2 I seem to get more random problems. Really though, what's best questions are left for you to explore and find out. Some people on these threads use their phone for most their computing needs and some barely even use their phone.

ondemand – Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see “up threshold” in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed.
interactive – Available in newer kernels, and becoming the default scaling option in some official Android kernels. The interactive governor is functionally similar to the ondemand governor with an even greater focus on responsiveness.
conservative – Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery.
performance – Available in most kernels. It will keep the CPU running at the “max” set value at all times. This is a bit more efficient than simply setting “max” and “min” to the same value and using ondemand because the system will not waste resources scanning for CPU load.
powersave – Available in some kernels. It will keep the CPU running at the “min” set value at all times.
userspace – A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor.
smartass – Included in some custom kernels. The smartass governor effectively gives the phone an automatic Screen Off profile, keeping speeds at a minimum when the phone is idle.

I've tried different configurations but always end up going for ondemand.
There is no "best governor", just like there's no best brand of beer. My favorite, however, is smartassv2. Great performance and battery life - probably one of the better compromises.
But I don't drink beer!

I have been experimenting with some various governors and have found that interactive and ondemand work best on the nexus 7. My question is which one will have better battery life on the nexus 7? Which one will have the least stuttering? Just curious. Everyone seems to state that interactive will be the better governor, but I tend to notice interactive heats up more in chrome. Anyone else notice this?
Any helps would be appreciated

When running low on battery I found conservative with runnable works the best for me. Undervolting by 50-100mV and running custom kernel plus ROM can also contribute. I always turn my WiFi and GPS off when not being used. I would not know of such imperceivable details between Interactive and Ondemand as battery, stutter or heat. Mine reaches 70 degress celsius under overclocked heavy benchmarking load.
For battery life, stick with interactive or conservative.
For less lag and stuttering, use ondemand or performance.

Wow, you couldn't be more wrong. You have it completely opposite. For better battery life, and not to have your frequency set to the highest value, almost at all times, go with ondemand. If you want less lag, and stuttering, but worse battery life, interactive.
Test it yourself with setcpu, and CPU spy, and you'll see exactly what I'm talking about.
So i just installed a dualboot setup on my SGS3. I use primary rom the latest cyanogen mod 10.1 nightly and for the secondary rom latest omega rom 4.1.2. For kernel i use the latest one from Siyah. The omega rom i use for intense gaming, multimedia, pictures, music, comunications and so on, and the cyanogen mod rom i use for daily calling/texting use. The omega rom i left untouched in terms of undervolting/underclocking as i need the power (but i really don't see any reason to OC my cpu/gpu as it runs perfectly smooth). But i heavily undervolted/underclocked my CPU/GPU in cyanogen rom for battery life as the following:
1. CPU: running only 2 cores at minimum of 200mhz and maximum of 1000mhz with -100mV undervolting
2. CPU undervolting steps i left untouched
3. my GPU runs at the following steps:
108mhz - 800mV
160mhz - 800mV
266mhz - 825mV
350mhz - 850mV
400mhz - 875mV
My system is perfectly stable even after heavy benchmarking, i reduced it to a galaxy nexus level of performance. For daily use in telephony/texting/social media is more than enaugh. I am now doing a full charge and run only on cyanogen mod with average use and auto brightness (2 mail clients, watsapp, facebook mess, yahoo mess, hangouts, 3G allways on) and i will report back with the battery stats after a full discharge. Here are some screenshots for my under voltage/clocking setup:
off topic : m am indragostit de o fata din focsani ... asa mare coincidenta ? )))))))))))))
on topic : only 2 cores .. even for best battery life i wouldn't use just 2 cores
Yea nice, i will try it asap

Any results?
Did you get a significant difference?
I hava try it and yes it has more battery life now but. Now i am back on my settings because i want it snappy and performance.

But i must say the idea With dualrom is perfect. I think i will do this with revolt Rom for gaming and cm 10.1 for battery.

I did pretty much the same thing yesterday underclocking to 1.2 GHz and deactivated 2 cores. it didn't help at all though unsurprisingly, since the phone runs on low MHz most of the time (when doing some reading or other undemanding stuff).

try this one and let me know as i have undervolted a lot and my settings doesnt have any lag,
siyah kernel is really gr8. i have undervolted my cpu to -100mv and by checking cpu spy and analysing at which frequency cpu is working more, i have undervolted that frequency to -125mv
and gpu setting is
266mhz - 850
350mhz - 875
440mhz - 900
533mhz - 950
600mhz - 975
Touch boost - 600mhz
android logger off
i find it out to be optimal good performance and better battery life.
You have lowered your GPU and CPU frequency to get better battery life compromising performance and i think by your settings u wud get max of more half an hour battery. I am getting nearly 5hr screen on time with my settings
Undervolting doesn't produce any noticeable battery gain. Your battery gains are probably from the fact that you use Siyah kernel.

i don't know exactly but i have set cpu freq to 1500mhz and gpu to 600mhz both of which are overclocked and undervolted producing bettery battery results. what i think and have read if u undervolt and overclock u might get better battery life with same performance.
and buddy i am regularly following ur post " Awesome Underrated Mods/Tweaks (24+ Battery Life) "
both adam kernel and boeffla kernel ( using zzmove governor) gives gud battery life results but my setting is overclocked and gpu to which would produce good result in 3d or heavy graphics gaming also.
i am not saying anything against but these are my thoughts and review.
I would like to know what u think. i am really a starter trying many things and need this community's support.

Thanks for the kind words. The most important factor in gaining battery life is the governor. Right now, zzmoove is the best. Boeffla, Googy, Siyah, Adam and Devil kernel all offer the zzmoove governor. As for undervolting or underclocking, it's not going to make a big difference so don't worry too much about it.
1500MHZ and 600MHZ is good.
The Best CPU Governor for Performance and also Battery life seems to be Interactive or Intellidemand.
For indepth Kernel Benchmarks and CPU Governor tests go to my thread here: http://forum.xda-developers.com/showthread.php?t=2625656
Here are SunSpider 1.0.2 benchmarks to prove the point.
(Lower is better)
ondemand: 1,200ms
intellidemand: 540ms
interactive: 520ms
conservative: 650ms
iPhone 5s:450ms
Conclusion: It is amazing that with this phone we can achieve performance that is close to the 64bit processor of the iPhone 5S. Screw Apple. (Just Kidding) Interactive is the best CPU governor. The end.
Lastly, you may wonder why I only posted Sunspider Benchmark results because that is only a javascript test and doesn't prove how the kernel will perform overall. First of all let me state that those numbers are after extensive testing under numerous different Stock and KitKat roms and Kernel combinations. Secondly, in terms of AnTuTu and Quadrant scores, you can expect them to be the same across all the CPU governors above. But the sunspider can be helpful in gauging browser performance. And since most users browse the web on their smartphones, it is wise to switch away from the default ondemand or ondemanplus which is a much more conservative version of ondemand, and instead use intellidemand or interactive or conservative.
It is interesting that conservative provides good performance and sunspider results. Maybe if you really want to be sure you have good battery life, you should stick with conservative. Although in all honesty, battery life is dependent on your brightness, and subsequently amount of screen on time, and then of course, the amount of CPU intensive tasks you perform like gaming, or Web Browsing. So differences between governors and battery life will be minimal if you do not adjust your user behavior...
I'm using a LS980 Sprint LG G2. I suspect that across variants results should be the same since SoC are based on the Snapdragon 800.
Conservative micro stuttered too much for my liking. Stuck to interactive.
