[Q] clocking cpu

i am fairly new to rooting phones. i just installed cyanogen 7 on my htc hero. works much faster than the stock. had heard that you can overclock the cpu. i downloaded CPUmaster free and lets me clock cpu to 768MHz. have been doing some research on this and have come across a few things. so really just one question; 1) what is the fastest you can clock the cpu with it still being stable?
help with this would be very much appreciated!

Depends on a variety of factors and every Hero is different. Depends on the ROM your running, kernel, etc. You can play around with capped and uncapped kernels but no one can really give you an exact # but you..u'll just have to try tinkering with the settings. If your wise you will just select one of the governors located in Cyanogenmod Settings. I prefer SmartassV2,min. 362 max 691 its efficient and takes care of everything while prolonging the life of your battery. Also remember that overclocking for an extended period of time will overheat your phone and could cause damage, so keep an eye on the core temp while playing with ur cpu settings.

Some phones can't take more than 691, some can handle 768. I have found, for my phone, that 245/710 works great for me. I can see a marked improvement in snappiness at 710 over 691, but not really much at higher frequencies.
I used to use OnDemand as my scheduler, but with the newer .35 kernel I have liked the SmartassV2; I don't have any issues with music cutting out like i would with smartass or interactive. CM7, or most any of the roms built off of that, have the option in CM Settings to adjust both the frequency and governor so you don't need to install a 3rd party app to do so (it's under the "performance" heading). I also like to go into the spare parts app and set my animations to fast; that's just me though. I think the new CM7 builds have Jaybob's .35 kernel now instead of the .29. I have not seen an uncapped kernel that goes beyond 768 in a long time. There was one that jasonmaloney compiled that did 806 (I think) but that was pulled by him as it isn't good for the phone. just test it out and see what you like with what you have installed on your phone. Every phone is different even though they are the same.

[KERNEL][AOSP] LorD ClockaN (lordmodUEv8.5-CFS-VIVO-2.0)

The new kernel by LorD ClockaN for AOSP(cyanogen and MIUI) roms is here.
http://www.multiupload.com/YQTRBBDO3B
http://www.4shared.com/zip/VC9M-tPU/lordmodUEv85-CFS-VIVO-20.html
This is 8.6b3 of his DHD kernel for vivo.
Please try it and post reviews which will help him to further work on incredible s kernels.
A big thanks to LorD ClockaN for his great kernels.
Governors explained: (Thanks to LorD ClockaN )
*interactive - Instead of sampling the cpu at a specified rate, the governor will scale the cpu frequency up when coming out of idle.When the cpu comes out of idle, a timer is configured to fire within 1-2 ticks. If the cpu is 100% busy from exiting idle to when the timer fires then we assume the cpu is underpowered and ramp to MAX speed.
*smartass - Is an improved version of interactive governor.
*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.
*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.
*brazilianwax - Very agresive version of smartass.
*interactiveX - Tweaked Interactive governor by Imoseyon by adding more features like suspend/wake profile.
*ondemandX - Tweaked and ported from 2.6.38 base Ondemand governor by Imoseyon by adding more features like suspend/wake profile.
P.S: This kernel is not for Sense Roms !

Installed with #146.
Boot is slow.
Bootanimation don't show correct.
A lot of lag.
Going back to v1.

this kernel for sence or cynagon or miui ?

aosp (cm7, miui). it says so on the first post.

Did a restor and reflashed the new v. 2.0 Kernel, but same problems as first time.
The strange thing is that test score with Quadrant is 3089 with both Kernels.

any changelog?

accidently im install to sence rom, this kernel accepted & working but i dont know others reflect like sms/call delay etc .... can someone test it!

Anyone else tried it? it is running fine on my miui rom. boot time was also good. couldn't find any bug in the bootanimation (maybe a slight lag in the animation).
Edit: felt a very slight lag while moving pics in the gallery.

Kernel is working fine.. Can't feel any difference between previous version and this.. But still Two Way call recording and in call audio boosts are missing.. Need the latter badly..
The only difference I feel better from Tiamat kernel is, this one does better fps in 3d and 2d animations..

I use this with CM nighlty 146 too.
booting is the same as v1.
but at governor "conservative" ,this version is much lag than V1.
For me ,V1 is faster responding than V2.
no other issue.

How is this kernel for battery life? Cm7

hey you promised us a new kernel after this to improve the small bugs...please if you get time then provide us with it...your kernels are too good

Does this kernel work with Virtuous Quattro or is it only for CM?
Both AOSP and so on? Don't kill me if this was stupid to ask

[KERNEL] Gamma Custom Kernel XT890 (Version 6.0.2, Linux 3.0.101+)

DESCRIPTION
So this is a cooked RazR i boot.img that contains a custom compiled Kernel for our device, it was patched to be kept up to date and has some changes to help on battery savings, plus some cpu-freq drivers which which help our device a lot.
InteractiveX2 CPU Governor -- Like Interactive, and fine tweaked to only jump to 1.8 GHz on lighter/faster load increases, comes with a screen-off profile to lock down the frequency and offlinining of the rest of the CPU's defined as non-boot -- being an SMT processor this makes it easier to get the phone to deep sleep even when it wakes up to do something by reducing the complexity of the system.
Conservative CPU Governor -- Similar to ondemand. However, before the governor takes this lower frequency and slower clocked in the upper area, which has positive effects on the battery life.
Ondemand CPU Governor (Re)added -- it was originaly on ICS stock Kernel, it adjusts the CPU frequency to the given requirements, however quickly clocked in the upper frequency range to ensure smooth working.
Performance CPU Governor -- this will clock the CPU frequency to the top, not recommended for prolonged use.
SimpleIO Scheduler (Default) -- is a mixture of Noop & Deadline and one of my favorites.
V(R) IO Scheduler -- is the best scheduler for benchmarks, in everyday use can become unstable.
BFQ IO Scheduler -- A proportional-share storage-I/O scheduler that also supports hierarchical scheduling with a cgroups interface with Low latency and high throughput.
ROW IO Scheduler -- This one is very battery friendly and now my favorite for mobile decies by it's simplicity and responsiveness.
It is known to work on stock & stock based ROM's (such as this one where it is included).
As of other differences there are a lot of GNU compiler flags optimizations, by knowing that the compiler wouldn't know some vital information since it is a remote target different than from where I am compiling so I decided to be pretty explicit.

NOTES
For more information regarding governors, schedulers, modules, etc visit this thread by forum member droidphile.
This is my personal experience to other people on compiler flags, if you guys want to try -O3 straight ahead you will face issues on battery readings unless you remove the -ftree-vectorize flags on the battery modules that get compiled.
[IMPORTANT] For changing the CPU governor please use No-frills CPU Control, Since other apps such as SetCPU and AnTuTu CPU Master both only change CPU0 and may cause conflicts.
INSTRUCTIONS
You MUST be unlocked, and to take full advantage of other modules it is recommend to be rooted.
I will put something more descriptive here, but you can flash it with fastboot by doing: fastboot -i 8888 flash boot <boot.img>.
THANKS TO OTHERS
First of all thanks to Matorola/Intel for putting the main source and for Turl on giving me some info when unpacking/packing the boot images. Also to mattlgroff for the tutorial on unlocking the phone, more thanks to imoseyon and Mike Chan for providing the interactiveX2 source code and changes, it it is now my favorite CPU governor and also to HSD-Pilot for posting this originally on another forum -- I based my formatting from his post.

So is this kernel designed for speed or battery life, or a mixture of both?
Also will this work on the 91.2.26001 JB.EU rom?

By default for a mixture of both. But can be further chose different governors and parameters of the governors for different choices for the user. You can for example choose conservative governor and get more battery life and less performance.
And yes It can be used on that ROM. :good:

It works on jelly bean alright... but with this I'm missing the features of the Arman AIO boot v4 and I just can't live without it...

Yeah, it was internal changes and some screwing around while playing with it. Aiming for more features and once a 'finalized' kernel build is there I will probably do change-logs and change the scheme of numbering.

Hey, what are the changes in V1.7.1 compared to 1.7?

Tried to fix and make SavagedZen more reponsive, but it is a weird governor, and also included InteractiveX in the meantime (no bug there).
Will probably just put into Github after this change so other people can see the changelogs.

Thanks for reply - Flashed it already :good:

well I would comment on your topic of rom ([ROM] Stock 4.1.2 JB optimized - Deblurred AOSP + 4.2 Kernel + extras). but as it only involves the kernel decided to post it here ..
good this new government "SavagedZen" is weird! I did not like, played some games, subway surfers, temple run 2, etc ... all caught. then modified to smartassV2, and now games are perfect and without lagg, I have helped with my feedback

Damn, ok and thanks! ... so InteractiveX is not functional yet sounds like it must have something to do with the early suspend portion -- will eventually fix it. Good thing is that smartassV2 works flawless!

Nice work on the governors!
I remembered some governor benchmarks I read a while ago on this forum, and I thought you might be interested in it:
[REF][GUIDE] Battery Saving Governor Benchmarks
Some interesting quotes from the above thread:
the difference between the best (smartassV2) and worst drain (lazy) is 0.05mA (a tiny amount)
Click to expand...
Click to collapse
choosing SmartassV2 over Lazy would prevent about 600mA being wasted in one hour. To put this in context, that is enough to power your screen for 3 seconds (assuming a drain of 200mA).

Furthermore, I remember another thread (which I have not found), which showed that governors which did not jump straight to the highest frequency could actually negatively impact the battery life. The reason behind it is that CPU usage is only a fraction of the battery drain, and having a slower CPU means applications have to spend longer in active state, thereby also causing other components battery drain over a longer period of time. The display is the biggest battery eater, followed by the radios.
Basically, what I trying to say, is (most) governors have no perceptible impact on battery life, and I believe users who report otherwise suffer from the placebo effect. So I think focusing on a stable default governor which gives a smooth lag free experience is the way to go.

I agree for the most part but that really depends a lot on the type of processor and SoC capabilities, for phones like us I focused on the tweaked smartassV2 further to get it to ramp up and down faster, and it is noticeable smoother. , good battery life since it ramps down better than the on-demand or interactive governors here!
SmartassV2 was the winner on our testing too so we left that one . I just wanted to get InteractiveX working on it for future flexibility and the days that I messed up with SavagedZen it was just an experiment as I had never tried it before -- the results was that I did not like it a lot or I ported it wrong! haha

Friend'm using interactiveX governor since yesterday, andthe results seem to be good and had no lagg dabateria useful life is good (since I am a hard-user).
but honestly the samatassV2 is better, it seems that runs smoother on my device!
but just wanted to note that the InteractiveX is working!
sorry for bad english

Will do but it may be done in the next month, Thanks for your suggestion.

First of all THANK YOU for spending your time on this and sharing your result with us!
Just flashed the kernel! Good news...nothing is bricked
CPU Spy Plus indeed shows 1836 Mhz used! I did´t do anything for that.
You might re-think this. Using 1512Mhz instead by default and let the users choose that high speed CPU mode themselves as it may not be stable on all devices.
That 324Mhz added is a huge step...there is no step in between possible?
What about voltages. Did you modify anything? Is the voltage raised to achieve the high cpu frequency? Please post some more information about what happens here...
In fact I´m just running Antutu to see general stability on my device.
VERY BAD score. Before your kenel there were 20300 points. Now with OC only 19746.
=====================================================================
EDIT: Just recognized.... several questions are being answered by Antutu CPU Master.
1512 IS USED by default!
1620Mhz and 1728 Mhz are there to choose and of course finally the 1836Mhz.
Scaling is interactive by default (changed to my fav ondemand)
I/O Scheduler is cfq by default (changed to my fav noop)
Antutu Score @ 1836Mhz: 16077Mhz ???
Lower than without OC? Needs retesting (14230 point when setting max to 1836Mhz and Min to 1512Mhz(!!!???)...maybe the benchmark is wrong...Will give it some time to see if I myself feel a speedup.
After Restart Antutu Score ends up @ 19761 points...not bad. but clearyl not enough looking at the massice OC done. REBOOT! Tab just rebooted! So 1836Mhz is not stable at mine! Trying 1728Mhz now instead.
18139 points....this kernel lacks some serious power if we can believe the scores of antutu. This is a V0.1 so nothing to worry too soon. You´ll make it find it´s power
Switched back to kernel from pulser_g2 (http://forum.xda-developers.com/showthread.php?t=2444452) and 19908 points without any OC! You may look into it.
But please answer the other questiones I wasn´t able to clear myself.

Sorry for my late,
I've tested Antutu with 1512MHz and 1836MHz. For my Tablet Z, I got ~20000 (1512MHz) and ~23000 (1836MHz).
My Tablet Z has fast binning CPU. Can you please tell me which binning your CPU is? Thank you!

hard to tell...did taht thing in Terminal emulator....it tells me "1".
Not fast or slow or anything...

Don´t know....after the disastrous performance of the first release I of course switched back to stock.
Now there is the new version which does not cut performance in stock mode.
I´ll OC now to 1728 Mhz and see how it performs with that....battery life is not really good with stock so if you are already asking...FORGET ABOUT alternative kernels not optimized for battery.
That is why I don´t use CM oder AOKP on my Note1. I just eats the battery for breakfast....
OK OC just seemed to scale...20300 points (ca. 19300 at stock speed)...trying 1836 Mhz now.
17389 points....clear drawback....possibly because my device seems to have a bad CPU from what I´ve learned....wanted to use the 17xx Mhz anyway....oops....device just rebooted....my device just isn´t capable of the max cpu setting. :crying:
Anyway the working 1728 Mhz working is great news!
Will give it further testing...

I have two APQ8064 devices, Nexus 4 and Tablet Z. Nexus 4 is 0 (slow), it will reboot sometimes even on [email protected], the Antutu would force close and red light of death would happen if you ignore it and attempt to run again. While my Tablet Z is 2 (fast), this can run at [email protected] and got 23XXX in Antutu.
I don't have an idea which frequency can the 1 (nominal) APQ8064 clock at, but I think [email protected] will be OK. Also, keep eyes on the CPU float-point section in Antutu. At 1512Mhz, it is around 2000. At 1836MHz, it is around 2200. If this drop lower, just pull up the voltage BUT NOT TOO MUCH!!!

Raising voltage is not an option to me. But anyway...which app do you use for that on tablet Z?
What App do you use for cou control?
I use No-frills. Do you change "interactive" and or "cfq"?
Numbers right after reboot and stopping some unused apps...just stock apps running...
2729 / 930 / 1112 / 1050 / 511 / 927 / 1436 / 5278 / 696 / 600
>>> 15269 points @ stock !!!
switching back to stock....

I would like to know this as well. Also, how do you check to see which processor you have? (0,1,2; slow, nominal, fast)

What is the terminal command to find out? I also considered custom retelling to add some processing oomph. On a per app basis, but reading this... Stock SGP311 on 4.2.2 is chugging fine just north of 20000 points on Antutu. Can we compare Versions? Mine is 3.3.1. I faintly recall reading they mixed up some benchmarking internals because some corporations found loopholes to cheat / inflate scores on new to market devices, maybe that's the discrepancy there?
Another wild thought, could there maybe be, aside from different CPU Models, different kinds of cache / memory scattered through the devices? Would not be the first time a sub par. Cache/Memory bottleneck severely strangled a nominally and factually quicker CPU into much lower overall results. Much depends on weighting within Antutu

Man, what happened with your kernel? We need some stock kernels for 4.3

[Kernel]NN-J-Kernel-LP-T710/810-5.1.1-3/10/16

This is the BOJ1 version of NN-kernel. It's going to go in a little different direction than the previous kernel. And I'm not very good with Git. So may I present to you.....
NN-J-Kernel​
This will work on the T710 and 810 Wifi only models. I built this for my BNN Nook, but it works with other 710's and 810's.
You flash this at your own risk. There's the discaimer. :silly:​
Install instructions:
You MUST HAVE ROOT and TWRP installed to flash this!!
It's built on Lollipop 5.1.1 - I have no idea what will happen if you flash this on anything else!!
REMOVE SYNAPSE "set on boot" BEFORE INSTALLING!!!
Flash kernel then wipe cache and dalvic
Reboot and profit!!
Changelog
V1.3
GPU Control
UV now possible as well as select frequency
Samsung has the Max listed as 600Mhz. I'm pretty sure its 700 as thats what I've been using this at. Just an FYI
V1.2
Charge Control for battery - It's the best I can do for a "Faster Charge". Be careful. This can shorten the life of your battery. Or worse, ruin it if you change from default. You have been warned.
Maybe some other minor stuff
Also see/read this post

Memory controls
_______________
V1
OJ1 source
Synapse tuner - it's the only one that seems to work. Finally, after much effort.
Selinux Permissive
KNOX removed
Init.d support
Enabled OTG
Updated Frandom
Govs enabled- Powersave, Conservative, Ondemand - removed Userspace
Some optimizations

And yes, Schedulers are fixed in this.

Flashed, running perfectly so far....
Thank you for your work.

I flashed this kernel (oj1-based) and the NN kernel (oh7-based) and let antutu benchmark the performance of both kernels (both default settings). This kernel wins outstanding!

Is this the "newer" one yes ?

Awesome! Thanks, it's nice to see some development on thus tablet. Otherwise there is nothing to flash

I did the same and the OJ Kernel is slower for me. Did 2 tests. 69-70k in old Kernel while i getting 62-65 with OJ1. Any idea ? How much do you get?

I tried setting max core to 2.x ghz but its not working, is it fixed to 1.9 ghz=no oc enabled so far?
Very strange, worked before i think. Just have Synapse installed and also wiped caches after flashing.
Any idea?

This kernel has no OC function, at least until now.

Actually, right now, it has no OC or extras. This is just the start. It's in the changelog.
Antutu scores, for me are 66-67000.
OC/UC and UV will be coming shortly. It's done. I just can't find out why Big 1500 ghz and Little 1300ghz are favored. Messed with a lot of stuff to no avail. Yet

V1.1 is up!!
SEE/READ changelog as there is a ton of stuff in it now. Both Kernel and Synapse. Yea for Hotplug!!!
Google "HMP" so you can understand it better. Big/Little core control. Little cores are ALWAYS online.

Think I found a way to get us a Fast Charge. Gotta finish and test it. So far it's looking good.

Incredible. Fast charge on our tab s2? I hope so?

Great job! Thanks! Flashed and works perfectly, new synapse settings seems cool. UC seems to work fine.
Shiuldnwebuse the DVFS app as mentioned in synapse?

Thanks. I have no idea if that app helps as I'm new to Samsung. If you try it, make a backup first.
Everything works fine without it though.
Can you say Fast Charge?!!!!!
I had to port Hotplug and Fast charge, but I think we're good to go. I still need to put finishing touches and build for both 710/810. But it should be out tomorrow IF my Tab doesn't meltdown while charging tonight. :silly:
Edit: Also, remember that as with everything computer, Fast Charge will be limited by Thermals. Just like CPU/GPU.

It wont really be fast charge as our tab doesn't support it

Interesting. Guess we'll find out. I have been able to vary the voltages while charging. Up and down. But as I said, thermals will probably limit it.
Edit. Let's call it "Charge Control" then.

Sorry me being an idiot. Will be cool to see our tabs charge a little.bit quicker

Thank you very much for the kernel!
Running 1.1 with
A57 cores at 1300/500 and UV 50mV
A53 cores at 1000/200 and UV 25mV
2 A57 cores online
FIOPS scheduler, 2048 readahead
Gentle Fair Sleepers enabled
It's running snappy! Will watch battery life
P. S.: Why doesn't Synapse have live monitoring where one can see which frequency each core has at the moment? Just like other kernel tuners?

They are there. On the core screen at the top. Just wiggle the screen and you'll see it change. Big cores don't move as much until there is demand for them.
V1.2 is in the OP! With "Charge Control" See/read changelog for warnings.
This was a big port, and everything seems to be working. Just watch your tab for temps just to be sure it can handle the voltages. We should be ok, as it's built in and not on it's own. Meaning that all of Samsungs limits are still there. So Thermals should hold it from melting down. My Tab has been plugged in all night and is just fine.
This has all kinds of cable configurations, so it should cover about everything out there. I only use AC and USB but left all the others in for all of you.
One more time, we should be OK using Charge Control, but BE WARNED that it may ruin your battery and shorten battery life span. You use this at your own risk.
