Thoughts on OverClocking Sensation

Hey guys,
Ive been using SetCPU since it was fixed for the sensation. I am curious about what others have observed as far as battery life and performance goes.
I am running 1.8Ghz with a cpu voltage of 1.265V (1265000uV).
My battery doesnt last all that long despite all the profiles I have in place. I guess thats expected when you overclock by that much, huh? Is it worth it though?
Im sure more of you out there have experience to share. Im not talking Quadrant and benchmark scores, Im talking REAL use!
I am beginning to feel that dropping the frequency down may be in order since I cannot find anything that needs 1.8Ghz to work on this phone. Plus, less frequency means less required voltage. That would mean more battery!
Anyone care to chime in with their overclock frequency + voltage and experience?
Matt

I'm also interested in getting some input from other users, without having to clog up the respective overclocking threads in the Development section.
Yesterday after work, I set up the 1.5Ghz Undervolted option using utking's tool (http://forum.xda-developers.com/showthread.php?t=1168707). I didn't see too much need to push my CPU too hard, and a stable UV always piques my interest.
I created a couple of basic SetCPU profiles (screen off, battery below 20%, temperature < 50C), and scaling on demand up to 1512Mhz, my phone took about another 7-8 hours of moderately heavy use (Navigation, Maps, Yelp, photos, etc.) before it was on its last legs.
Bear in mind that I've been using the Anker 1900mAh battery. But even after the OC-UV that I set up, this was at least as good of battery usage as before without any SetCPU or overclocking, and actually seemed to be a little bit better to be honest.

I just dropped down to 1.6Ghz @ 1.26V...
I couldn't keep my phone from freezing with anything less than 1.26V @ 1.6Ghz. We will see how this goes for a few days and compare to my previous 1.8Ghz @ 1.265V.
So far, speed seems to be FASTER than 1.8Ghz. My Quadrant score (only being used here for comparison reasons) was 2700 right off the bat, whereas 1.8Ghz would peak around 2700-2800 after several tries.
The carousel works much better! I can swipe through quickly and have it scroll with zero lag. I can also fast swipe and watch is spin nicely!
Google Earth and Maps is about the same as 1.8Ghz.
Before, at 1.8Ghz, I could probably get 16 hours out of my phone with VERY LIGHT use. (A few 2min phone calls, check mail throughout the day, check the web a little). I am charging the phone up and will report back later.

I went down from 1.62 UV to 1.5 UV,because I could not see any difference in general use nad in benchmarks(except Quadrant) and battery consumption is much bigger with 1.62 with exact same profiles on setCpu.I think that this is best compromise between speed and battery life and as far as I know this is native clock speed of 8260 Snapdragon.

How simple is it to temp-root and overclock? I am really only interested in overclocking to speed up Sense, and you said it performs better with a speed boost.
Sent from my HTC Sensation 4G using XDA Premium App

Very,very easy,just read this tread :http://forum.xda-developers.com/showthread.php?t=1168707

I have mine undervolted at VDD_1175000 and 1500MHz. I like it very much...makes a big difference in quadarant score, but not sure in reality how much faster. Battery life is fine (when the phone is on). Have not experiened FC's
I have modified eugenes batch file to push my kernel file and preferred speed after perma-temp-root and now is all in one click...

So here is a little update:
Its been about 8 hours since full charge and I am at 55% battery left.
1.6Ghz @ 1.26V, On Demand.
Ive been checking email, making a few calls, and surfing the net with both wifi and GPRS (was out of the network, away from 4G). I also played Angry birds for a little bit and showed off Google Maps and Earth to my Mom.
Now that Im back home, ive turned back on 4G...
Ive noticed a slight amount of hesitation while opening and closing things, but nothing bad.
I havent had any profiles kick in yet, but they will soon with the battery getting low. I will resist charging the phone and see if I make it through the night, using it as I need it. I will report tomorrow.

I must be doing something wrong.
I am rooted and running LeeDriods 1.2 Rom. When I launch setcpu the only options i have are 1000 mghz? WTF am i doing wrong?

i think at LeeDroid 1.2 you must not use setcpu but Demon control?

Hmmm, okay. I saw where set cpu was updated for the sensation in the latest release but it doesn't seem to support overclocking with this rom.

Shame that as i was about to get that rom and flash it onto my phone, glad i came in here now
Running Leedroid 1.0
Kernel @ 1.7ghz max, i have it set to 1.5ghz and 192mhz
Runs hot when i play finger racing or reckless racing or modern combat 2 or something intensive, but besides the heat, it drains just like it normally would to be honest, maybe a little quicker, definite speed increase in overall user experience, without an OC the rom just flops, better than stock but just crap, OC is needed.

[Q] Will mine SGS2 harm if I cap CPU on maximum capacity??

I have downloaded SetCPU in my SGS2 and capped my processor to max-1200mhz and min-600mhz. Will it harm my phone if I switch to performance mode which is max & min at 1200mhz (full capacity).

Well I think it depends on the hardware. But I would never recommend to push it at the max frequency, first of all you will decrease your battery life as well as your CPU lifetime since it will produce more heat.
Obviously it can depends of how many times a day you are using your phone to that max clock. If you are experiencing spontanous reboots that means the clock is too high, if not, well.. up to you to keep it like that.
I overcloked my Hero at 710 Mhz for about 2 years (the max capacity it's 748Mhz) and my CPU suppose to run on stock at 525mhz. I can feel my phone been a little hotter compare to the original clock but it has survived until now. (finger crossed)
But seriously.... ask yourself do you REALLY need all that power from your phone?

Thermal throttling and hotplug settings

I have been able to fix quite a bit of thermal throttling experienced in multiple benchmark runs by tweaking with the thermal-engine configuration file. With just a few changes and with the copper shim mod I can now run geekbench for as many five times with almost no drop in score. After that I get no thermal throttling in single core but I have it setup to disable two cores after it hits 55C CPU temp in core 4 and 7. I use CPU Z to see actual CPU temp from the sensor readings. Even after 8 Geekbench runs the two cores are still running at full speed and the phone is registering 44C. It's warm but not hot by any means.
If anyone is interested in playing around with it just look for the file in \System\etc\thermal-engine-8994.conf
Most of it is just two adjustments. One for Max temperature at which it will throttle and the one below is the temperature at which throttling stops.

Without your copper shim mod have you found any better but safe values we can try?
At least no thermal throttle until 55 celsiius

It should be safe without the copper shim. The thermal pad it comes with works pretty well. It will still thermal throttle to whatever temperature you set it at so it won't cause any harm.
I've set the Big cluster to a max of 65C and a single A57 core to up to 71C and haven't had any problems yet. I used to get horrible performance with PPSSPP emulator. When running Tony Hawk Project 8 in PPSSPP after 30 seconds of gameplay It used to drop to 6fps and now it can sustain over 20fps after reaching 71C on a single A57 core. I only saw a maximum battery temperature of 40C and the device wasn't noticeably warmer than it was with the default thermal settings.

Well yes. Except that's the little cluster and they don't get that hot normally. It's the big cluster that needs to be modified. I also tuned my display thermals so the screen wouldn't get so dim when the phone gets warm. Here you can look over my configuration if you want.

Thanks i will try them!!

your settings somehow "unlocked" my phones cpu. lol in geekbench I found an increase of performance of 200 points in multicore from 4020 I had before maximum , now nearly 4300 .It is impressive. also if I run 6-7 geekbench in a row there is a decrease everytime ex 4200 4050 3900 3600..... but temperature stays 45 degree.
I will test them more later.

Thanks for sharing your results. That's the highest multi core score I've seen on our phones. I never gotten that high of a multi core score. Glad to help. My configuration also tweaked the battery thermal settings so now you should see faster charge times as well. The default charge rates had really conservative thermal settings and the high speed charge would drop after a while but now it will 2.2 to 2.4 amp charge through the whole charge.

Yes indeed i saw a difference in chargin thanks for your effort in the configuration. I am not very fond of benchmarks but i run some in my devices after magor changes (firmware....). This device should have been speedier because of the full hd snapdragon 810 combination. I wonder if we delete the thermal config is the device gonna be speedier? I am waiting for 5.1.1 hoping for smoother rom. Lets hope soneone unlocks the bootloader!!!! I took my precautions disabling MLT lol

I guess it depends on what you're doing but I probably wouldn't play any 3d games with those settings. Here's a copy of the original one https://www.dropbox.com/s/yb76q6qwanb9ujr/thermal-engine-8994.conf?dl=0

When you apply the settings you need to give time to the phone to 'absorve' them.
Run a couple of benchmarks, test a 4k video, reboot the phone 3-4 times, close it also.
I havent noticed higher tdmperature of 45 celsius.

I'm not sure what would happen if you just deleted the file. Maybe it'll revert to some default, or perhaps it won't thermal throttle at all which would result in auto shut off when it overheats. Probably not worth risking it without a custom recovery in case it doesn't boot.
I have notice that my phone is way quicker now. It was fast before but now it's a beast when I push it hard. Also things like PPSSPP emulator was useless with the default thermal throttling now it can beat my Tegra note 7 with 4 A15 cores at 2.1ghz at it.

Was there a problem with your settings? I noticed your settings you had shared on dropbox are no longer available.

The folder was deleted for some odd reason. I was able to restore it so the link should work now. Let me know how it works out for you.

A few questions about these settings.
-At the top where you have SS-Little_Cluster_management and SS-Big_Cluster_management is the set point the shutdown temp for the entire cluster?
-I think this one is self explanatory by the action listed but towards the middle where CPUx_MONITOR for each core is, is the threshold the temperature at which the entire phone shuts down?
-I'm not sure I am noticing the difference between SS-CPUx and CPU_HOTPLUG_MONITOR. Could you explain these?

I don't want to assume I know everything about this. Everything I know about the thermal configuration file I learned from seeing others modify the LG G3 thermal config file. I also learned some by experimenting with my G Flex 2.
In my understanding SS-Little_Cluster_management and SS-Big_Cluster_management is the temperature at which the Cluster will thermal throttle when all cores in the cluster are being used at once. From what I've seen anything with "action_type 10000" means thermal throttle. The closest thing I can think off that works like that is how Intel I5 and I7 will limit turbo speed when more than one core is being used. Except in our case this is to prevent higher speeds when it reaches a certain temperature. So lets say your phone is running some heavy multithreaded app now it's going to follow the rules set in Cluster_management. The default Big Cluster temperature is set to start slowing things down when temperature reaches 48C and to not go back to full speed until the temperature drops down to 38C. One thing I find interesting is that at about 48C cluster temperatures was about where the Big cores would drop to a max of 1.5 ghz. So I'm just guessing that this setting may play a big part on the big cores max speed.
[CPUx_MONITOR] seems to shutdown the phone when the core reaches a certain temperature threshold of 120 C and I assume will not allow it to turn back on until it drops below 115C.
[SS-CPUx] on a big core seems to slow the specific core down when it reaches a temperature threshold of 85C and to not allow it to go to full speed until it drops below 55C. However this rule can be overwritten by [CPUx_HOTPLUG_MONITOR] which can shut down a core even if it hasn't reached it's maximum temperature threshold.
[CPUx_HOTPLUG_MONITOR] just tells the specific core to turn off once it reaches the temperature threshold specified. On the default configuration core 4 and 7 are set to turn off when their temperature goes above 50C. After that core 5 turns off at 58C and even core 6 turns off at 61C. At which point only the small cores will remain on.
I hope that helps somewhat.

My processor is slower than it should be!

I bought the phone today, but I think it's way slower than it should be. I know that the LG G Flex 2 has a Qualcomm Snapdragon 810 with 2.0 GHz quad core and a 1.5 Ghz quad core (octa core) CPU, but after i have runned a couple of benchmark tests in Antutu, I got a score between 35000 to 40000! That's way slower than Samsung Galaxy S5's Snapdragon 801! I thought that it whould get a score over 50000 When I see info about my CPU in Antutu after bemchmark test, it stands that the first four cores has a frequency of 1.5 GHz, while the other four cores has a frequency of 0.9 GHz (two of them are "sleeping" a lot)! Is it possible to fix that? I hope so. I've got the 16GB version with 2GB of DDR4 RAM. The device is upgraded to 5.1.1 Lollipop. (Sorry for bad English, I'm from Norway)

i got mine at Tuesday. I can pretty much say i never experienced a lag before even tho i had many apps in the recent apps tab and also i was playing high quality games and it got a little bit hot but still it was working flawless, very very fast. What i did after i updated to 5.1.1 i did a factory reset, then i downloaded only the apps that are indeed from lg apps such as calculator downloads quickremote (because most of them are useless and slow down the phone) and then i downloaded a custom launcher and greenify. Also use the google keyboard from google play store. better to use google's apps rather than lg's. Since then i never experianced any lag before. try it out. If u need more help tell me

That is really low. Go into settings and into battery saver and check if you maybe turned it on, and also see if you checked option to optimize battery in games.
Try restarting the phone and run antutu again, after a couple of minutes..

You are from a cold country so it should help. First try let rest the phone and launch antutu when it's at room temperature.
Then try with an ice pack on the back. It can be ice pack for injuries (kind of thick gel in plastic bag) or for cool box or ice chest, whatever you call it. But don't use it too long, you may have condensation inside the phone and it will trigger the humidity sticker (for your warranty).
Don't launch antutu after a reboot, as it's warm after a reboot. Or reboot and let it cool down first.

Is it possible to have a partially working processor?

It has come to my attention through benchmarks that my CPU is not performing anywhere near where it should be. It also has a -1C reading on Core 2 (technically the third core) in Synapse that occasionally flickers a temperature that is MUCH lower than the rest of the chip (like if the rest of the chip says 70, it will say 40 and it idles at 27C while the other cores don't go below 33C).
My AnTuTu is 62k and my AnTuTu beta is only 76k. In the AnTuTu beta, even the One M9 is destroying my chip (I only beat it on RAM score, Multi-Core, and 3D) - the UX scores are all about 25% under the throttled Snapdragon 810 and in the beta, the Note 5 should score almost 84k. The only benchmark that my phone is beating it on is the 3D benchmark (14602 to 13929).
If my CPU IS damaged... How on earth would I even go about getting T-Mobile to understand what I'm talking about? I mean the phone performs admirably anyway but if this isn't the performance I should be getting, I don't want to have a defective phone...

Is your phone working properly when doing phone things? Is it modified?
What software version are you on? Kernel?
We need all that.
By the way......scores don't really mean anything as It's a cellphone, not a gaming rig but understandable people want to test performance. Do you use your device mostly fire gaming? If so do you get any lagging dieing play now compared to before?
