Just tried 1.4 1.56GHz on my phone.

Wow/Amazing: Running at 648MHz it is nice and smooth and gave reasonable results on AnTuTu (3619), LinPack, CF (5036) & Quadrant (1809). Clearly not 1.56 or 1.78 standard but it seemed to underclock fine and so far worked very well for me. I have previously tried other kernels, yours and others. This is the best I've seen so far.

More importantly though the phone, even at this underclocked state, seems very responsive.

I am using a cleaned stock ROM (1.45.401.2) with SetCPU to limit the speed, simply to get more battery time. I know you said DON'T use them but it seems fine for me at the moment.

I have checked with CPUstats and it seems to be running at the asked for speed after the initial boot.

Many thanks Faux123

I can´t edit the vdd_levels too. If i make a change in root explorer and save (R/W), it says saved, but if i open vdd_levels again nothing has changed.

echo "-75000" > /sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels

How do you enter the echo command?

Is it adb or scriptmanager or ....? (sorry for noob question) :confused:
[HTC Sensation] faux123:
Sorry this can only be done via adb shell or terminal emulator. Editing file via root explorer or any editor will not have any effect.

@Faux

Tell me to fu** off if you like, but why did you lose your developer status? it seems obvious to me that you're a bit of whizz and this nastiness is definitely development in my opinion.

Thanks for making my phone what it should have been (and Mike1986)
[HTC Sensation] mrg02d:
I doubt faux would say that...Im sure its something that ought not be said in public, but I dont see why this "status" matters anyways. We all know faux does ALOT of work that HTC should be doing. If you know your a badass, you dont need others to say so. ;)

YAYUH just 1.78 on my sensation running revolution HD 3.1.1, smooth and extremely impressive. especially since my laptop is running 1.66 lol its amazing.

0.0.9 kernel didnt work for me just ate a bunch of bootloops. 0.1.2 worked like a charm and now im just waiting for a red theme to come out for me so i can have my 100 percent custom phone. (hint hint) Thanks guys
[HTC Sensation] 3c:
Just setting max frequency to its lowest does the trick very well, no need for an additional governor... This might just give you lags during screen-on...
[HTC Sensation] Joshhedge:
0.1.4 @ 1.78GHz didn't work at all for me, boot looped at every frequency I tried down to 1.2GHz from 1.78GHz :(
[HTC Sensation] SatScan:
Kernel 1.4 is a killer bee

Hoi Faux123,

Just want to let you know this 1.4 is a killer... so good!

Speed is great!

Batt live is top!

And it's stays cool!

Best kernel i have found overhere with IC Rom.

I hope 3c comes soon with a OC/OV-UC/UV (CPU/GPU) slidertool and this phone is the best around Xda.

Thank you!

I have v0.1.2 and it randomly reboots once a day and gets stuck in a boot loop until I pull the battery. Is there a new version of the kernel that resolves this?
[HTC Sensation] SatScan:
Hoi,

Use the search button and you know...

I'm on 1.4 :)

Greetings,
[HTC Sensation] 3c:
I hope too :D probably later today if I get the below issue resolved! but how?

EDIT: Never mind, it works now!? Not sure what happened yesterday... will double check again as I'm getting confused with this!
[HTC Sensation] SatScan:
OC with L2 sync and better batt live ... that's the trick...

Good to hear!

If you needed a betatester pm me.

The OC/UC etc is just starting... give it some time to find out the right settings.

I use system-panel to monitor how the cpu behave in daily use...

Greetings,
[HTC Sensation] 3c:
Will do, did you get both apps pro versions?

Why don't you use only one? how do you monitor cpu behavior in system panel? Better than System Tuner recorder? Does system panel records both CPU frequencies? I ought to try anyway.
[HTC Sensation] SatScan:
Hoi,

Yes i use the pro versions...

System-panel let see (live) both CPU's and have a monitor option to record in background what the cpu does... you can choose system/apps etc.

Greetings,
[HTC Sensation] joshndroid:
Can the settings for this be changed in cm7? Like min sleep, etc i would like a tad better battery

Edit: also Could we get a 1.6GHz kernel it would seem 1.78 is just a tad too much leading to loops could we get this happy medium faux?
[HTC Sensation] 3c:
Same in system tuner... Live Analysis shows CPU load/frequency/temperature and app consumption. While recording in the background... Also keeps all recording ready for use.

Anyway, was just out of curiosity.
[HTC Sensation] ajay83:
Hi Faux

I installed your kernal v0.1.4 1.7ghz Nohz and for me it's running fine so far.

Very happy =)

Was abit dubious at first as so many reports of it boot looping peoples phones but like you said "Not ALL chips are made equal".... and it's worked FINE.

I was running the nohz 1.5ghz 0.1.4 and upgraded to 1.7ghz a few hours ago. the JoeR

kernal just feels too choppy for me.

I also ran CF bench cause I read that it recognises BOTH cores and my scores were:

13117 native/ 3464 java/ 7325 overall

Thank you for your great work bud. =)
[HTC Sensation] Babbar Sher:
Hi, I would like to know the similarity between 0.1.0 and 0.1.4, these 2 kernel don't overheat my phone, after night of charging, 0.1.0 leaves temp. At 30c, while 0.1.4 goes upto 38c. And also how are 0.1.2 and 0.1.3 different from above kernels. Because 0.1.2 and 0.1.3 shut down my phone twice
[HTC Sensation] d3vilskid:
Phone burns up with latest .14 kernel on ctd 7.3 ROM. From 100 percent battery to 67 on 20 min. Doesn't seem like my phone is sleeping when screen off. I remember back in the g1 days two bugs was eating up the battle and that was display and android os two of which is apparent in the new kernel. Display eats 67 percent of battery in 40 min on idle.

PS. I have a tmo usa sensation.
[HTC Sensation] HannoSLM:
no such problem here

i am with mike's rom and clocked kernel 0.1.4 at 1.6 and everything is running amazingly fast

phone is cold, even during charing ...
[HTC Sensation] PeterGuru:
Very bazaar behaviour ...

I'm getting very strange behaviour ...

I just finished installing ARHD 3.1.1, and then Faux123 kernel 0.1.4 at 1.56GHz.

Now everytime I try to touch almost anything on any home screen, the screen jumps and flutters. Depending on where an icon is located, if I want to delete it by holding my finger down on it, I suddenly get a different home screen. I go back and try again and, a new home screen.

It's weird.

Any ideas as to what I need to do?

Oh, in case anyone asks, YES, I WIPED EVERYTHING BEFORE INSTALLING ANYTHING.

Oh, in case you ALSO ask, yes, I rebooted twice ... actually several times ... but the problem still exists. Going back to 0.1.3 to see if it solves the problem.

Thanks,

Peter

UP-DATE: I went back to v0.1.3 and everything's fine ... so it must be 0.1.4 that's having issues with my device.

I have overheating and low battery life with 0.1.4 kernel (1.53 Ghz version). Reverting back to 0.1.2 - the best for me at this time...

I created quick flashable zips package that puts the boot script in /system/etc/init.d that enables a , -25mv, -50mv, or -75mv under volt on all stepping, for those who want an quick and easy UV. PLEASE make a nandroid backup just in case ur chip cant handle that UV, or delete the file /system/etc/init.d/95oc. Enjoy

EDIT: REMOVED FILES , these arent working, try the files below, WIP
[HTC Sensation] tinker2000:
Hi again,

The zip didnt work for me...no change in vdd levels. Any idea why not?
[HTC Sensation] GabrielSousa:
after the boot of the sensation,

i go to CPUStats

and i can see in the first 40s of the boot the minimal is 1566Mhz (some times the sensation dont boot, i thinks this is the prob.)

but after 40s changes to 192.

its normal ?
[HTC Sensation] BigBoppa:
Same here, -75mV zip does not work.

After booting with installed zip i can adb shell "-75000"... once, so this one works.

a second run adb shell "-75000"... let phone crash.
[HTC Sensation] zimphishmonger:
Hmm...thats sorta strange. Not sure why, maybe the UV cant be set until Android has booted completely. This is one Faux is gonna need to answer, can we set UV settings on bot via init.d scripts? or does it need to be executed after Android is fully booted?

EDIT: as a test, Ive modified the three flashable zips to wait 3 minutes before attempting to apply the UV settings. Please test and let me know how these work. Thanks!
[HTC Sensation] BigBoppa:
I will test it tomorrow, it´s 2am here and i have to go up at 7am...so need some sleep...
[HTC Sensation] faux123:
The CPUFREQ vdd table is setup as soon as cpufreq driver is fully initialized and sysfs interface is ready to accept commands. I haven't tested inside an init.d, so I can't say about the timing. I've only tested with adb shell and terminal emulator, and of course both are done after phone has completed its booting process long ago...
[HTC Sensation] zimphishmonger:
I started at 3 min, and I will reduce until I find a good delay time (just using sleep) before executing the command to set UV. Thanks for ur help!
[HTC Sensation] zimphishmonger:
Well, ya....we dont have a permanent method to re-enable the UV, but its def working. It just needs a method to re-set that UV each boot (which Im working on via scripts ;) )
[HTC Sensation] Masrawy:
So this method via ADB is working and reliable? But I need to do it everytime I reboot right?

I there a way of doing this via Terminal Emulator? I don't always have a computer with me :p
[HTC Sensation] zimphishmonger:
Yup, you're actually typing in terminal whe you use adb shell :) its just echo "-75000" >/sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels for -75mv

Im having some issue getting the script to work automatically, but they def work when run manually or via gscript, Script Manager
[HTC Sensation] Masrawy:
so just to be sure I correctly understood, I'm kinda noob :p

I open terminal emulator on the phone, and just write the same thing?

echo "-75000" >/sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels

and I don't need to write SU before...

is that correct?

Day two of development :D

This is still in pre alpha stage. Ui is rough and many features have yet to be added. Undervolting, and more will be coming in the future as well.

(ps, that's my vibrant, so half of it doesn't work on my end, thus the # on cpu1)
[HTC Sensation] jlevy73:
Nice job Roman, looks promising.
[HTC Sensation] 3c:
Just to let you know guys that System Tuner has been updated and support undervolting your CPU with this kernel!

You can add a shortcut on your home screen for easy access, either CPU tweaks or Voltage table! (best with cpu tweaks to access boot settings easily).

Any feedback can be sent on the following locations:

XDA Thread

App web site

Search 'System Tuner' on Market or go on XDA thread above for QR Codes.

Enjoy.

Internet Pass Through & Wireless - update

Update on using Mike's ARHD with Faux kernel 0.1.2 NoHz Edition 1.56GHZ.

When using Mike1986's ARHD 3.0.1, both Internet Pass through and Wireless were working; Radio is 10.43a.9007.00u-10.51.9007.27-m3.

Summary : -

A) ARHD 3.0.1 ( mike ) = internet pass through & wireless > both working

B) ARHD 3.0.4 ( mike ) = internet pass through not working, but wireless working.

C) ARHD 3.0.4 + Faux v0.1.0 NoHz Edition 1.56GHZ.= internet pass through not working, but wireless working.

D) ARHD 3.0.4 + Faux v0.1.2 NoHz Edition 1.56GHZ. = wireless Not working, but internet pass through working.

E) ARHD 3.1.0 ( mike ) = wireless Not working, but internet pass through working.

F) ARHD 3.1.0 + Faux v0.1.3 NoHz Edition 1.56GHZ= wireless Not working, but internet pass through working.

After switching to recommended radio 10.56.9035.00u_10.14.9035.01_m, results same as above for items A, E and F. items C and D not tested.

Now the happy one . . . :D :D :D , after flashing

Mike's ARHD 3.1.1 ( built upon Faux kernel v0.1.4 )

both Wireless and Internet Pass Through are working :)

ps - on 1 of the PCs, after I upgraded to the latest HTC Sync driver version 3.0.5579 issued in Sep from HTC webby - then internet pass through works.

insane dude. what rom are you using?

asking because i cant get even near those scores eventhough my phone is running your kernel 0.1.4 @ 1.5ghz but highest quadrant is 1900 and the highest cf bench score ist about 5800 everything on 1.5ghz...

wondering how u get with 50% less clock speed 10 - 20% more performance?

i know its not all about benchmarks but i just wonder myself this since a long time because no matter what kernel i use, the scores are always about the same..

Can you hel me out?

Tried xboarder hybrid cm7 rom an hour ago and here the scores are really absolutly insane. 3000on quadrant first run and 7800 on cf but my biggest problem with it: it has no sense and i really love it!

Great job faux123!!!

I'm using your kernel 0.1.4 1.78G undervolted and everything is working fine. I'ts a first karnel that is not overheating my sensation. Non-stop testing and at the moment zero bugs for me. At 1.78Ghz gov performance: Quadrant 3129, CF 7262

i've forgot to ask you a question... Tell me faux123 is possible to make this kernel more overclockable?? 1,89Ghz like in demonspeed? I think some maniacs like me will love it
[HTC Sensation] schidddy:
hey now changed the rom and now i get much better results so everything is okay now :)

just one more question i u allow :)

can i make direct changes to the vdd table file on

/sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels

and will it directly be applied to both cpus?

thx for your hard and great work!!!

That's the lowest in system tuner. Don't know if that helps
[HTC Sensation] schidddy:
look at faux example on the vdd table on first page.

there are incremtental steps by 12500nv

faux can you give us some infos on that? :) dont know if this was already discused but can i juist edit that table on

/sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels

and are the voltages set to both cpus directly?

thx
[HTC Sensation] faux123:
Yes, it's a single table applied to both CPUs... I hacked it to work for all snapdragon dual core designs. ;)
[HTC Sensation] schidddy:
thank you m8, and what about incremental steps? me and bigBoppa had different answer on that question, which is correct, 12500 or 25000nv?

thx again in advance :)

Hey johnson8cyl,

can you help me again?

I bought System Tuner Pro, but I don´t find, where to undervolt?

I only can change the CPU Speed, but no idea where to change the Voltage.

[HTC Sensation] faux123:
The recommended increment is 12500 uv or 0.0125 volts (the new Snapdragon power regulator allows much finer adjustments than the older HTC phones).
[HTC Sensation] BigBoppa:
Sorry, i was wrong, i remember faux mentioned 12500 steps.

Strange: Doing a search "12500" in this thread doesn´t find the post of faux...

EDIT: faux was faster, like his kernel...
[HTC Sensation] faux123:
Look ^ ;)

Yes 015 is coming soon ;)
[HTC Sensation] johnson8cyl:
Had that problem too. Go to settings-applications-manage apps. Find system timer. Clear the data. Then it should be there when you open the app and go to CPU controls
[HTC Sensation] schidddy:
got another question m8, hope im not getting on your nerves. :D i tried editing the voltagetable already twice and lowered every frequency by 12500nv now but everytime i save it and look back at the file, its set back to original... also when i try to delete it, its saying cannot be deleted.

working with ES File Explorer (root enabled in options)

what am i doing wrong?
[HTC Sensation] johnson8cyl:
May be a stupid question. I see you said root enabled but did you tick the option to set system as r/w?
[HTC Sensation] BigBoppa:
You can´t edit the file vdd_levels.

Use adb shell or terminal emulator on the phone to enter:

echo "-12500" > /sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels

EDIT: HEHEHE, first!
[HTC Sensation] faux123:
The file can't be edited at all. You can only change the settings via terminal emulator, adb shell or shell scripts. See my op for examples. Romanbb and 3c are building apps to make uv easier for everyone. Romanbb's app will be open sourced. Very good of him for donating his time and effort for the community. Make sure to thank him once the app is available!
[HTC Sensation] schidddy:
thx to you two, great community here :)

EDIT:

hmm i really slowly feel ashame due asking so much...

when i enter the comand provided by you faux to lower all frequencies by 25000, it always says "permission denied"

using terminal emulator. im new to this android system an all sorry m8s
[HTC Sensation] Romanbb:
On that note, Alpha 1 will be available sometime today. As soon as Fauxy confirms the basic features work :)
[HTC Sensation] faux123:
Make you have super user / root permissions first by issuing "su" first via adb or terminal emulator
[HTC Sensation] schidddy:
Ok did this now enter terminal was given su rights :) after entering the comand, terminal wasnt saying anything, and after i checked the vdd_levels file, it still stays the same. Is this normal an i am on the right track? Now if i want to lower the voltages even more, can i just minus another 12500uv for example or do i have to add all subtractions so lets say first, i entered 25000 for all and i want to go another 12500 lower so the total substraction and final comand is 37500? I hope you people get what i mean, sorry my native language is not english as u can see :D cheers m8
