No overclock but undervolting

Hello Sebastian,

While I'm having a Sensation XE my CPU is already 1,5GHz.

Can you make a kernel which isn't overclocked but does have the undervolting so batterylife would improve.

For me I'd rather underclock from 1,5GHz to 1,2GHz and undervolt so my phone would last longer on the battery.

Maybe the're other users for who batterylife is more important than the fasthest phone.

Already thanks.
[HTC Sensation] c3d76:
Agreed, I'd really be interested in trying a UV 1.2 or 1.5 to see how battery lasts...

And thanks for the (existing) Kernels Sebastian!
[HTC Sensation] omar302:
Sebastian's 1.5 kernel is already undervolted. Refer to the OP description.
[HTC Sensation] votapero:
Hi Sebastian

Thanks for the new kernel. I tries them as well. My standard Sensation is runnung without boot-loops with:

- 1.2 GHz Standard ARHD 6.1.1

- 1.7 GHz normal volted

I get boot-loops every approx. 30 Secs. with:

- 1.5 Ghz (UV?)

- 1.7 GHz UV

So I suppose, some HTC Sensations have problems with the "under-voltage".

To be sure, can you make a 1.5 GHz "normal volted" Kernel? This would be very helpfull.

PS: Am I right that the 1.5 GHz is UV?

VPN Connection not Working anymore

Hi Sebastian-FM,

may be it is possible to enable ppp support for async serial ports &

ppp support for sync tty ports in the new kernel 3.0.16 again.

In Kernel 1.512 3.0.13 is everything working great. In Kernel 1.512 and 1.728 is it not working.

It seems to be missing PPP support so many VPN tools that use Point-to-Point Protocol do not work.

Could you check. Only if it is not so many work.....

[HTC Sensation] JethroCl:
Yes, me too! In SetCPU max is 1.5GHz...
[HTC Sensation] arachnid1970:
Just installed 1.72UV, so far stable on IC 4.4.3... System Tuner shows the right frequencie, maybe a bug from SetCPU?
[HTC Sensation] lindahl85:
Both 1.728ghz kernel does not work to overclock with virtuous inquisition v3.0 and firmware 3.24
[HTC Sensation] mat9v:
And what happens when you try? Bootloops, FCs, what?

You may be an unfortunate one with Sensation that does not work @1728 - too much overclock. You did download correct files? ;)
[HTC Sensation] youp20:
Hi, any one tried if new kernels support 2wcr?
[HTC Sensation] lindahl85:
I have tried those two kernels. The phone boots with both but i can only have 1.51ghz maximum. The kernel without undervolt boots with a default setting from 1.08ghz and goes to 1.51ghz

The phone is a Sensation XE
[HTC Sensation] sjh4:
tried the 1.7 undevolted overclock on my senstaion xe, running android revolution hd 6.1.1 rom, also tried on elegance rom and insertcoin 4.4.3 using latest fimware, on all three system properties show as running at 1.7ghz, but all benchmarks and setcpu show still at 1.5 and benchmark similar to standard 1.5, anyone any ideas whats happening here?

thanks:(
[HTC Sensation] mat9v:
First, try System Tuner (or System Tuner Pro if you want to pay for few functions) change governor to performance and set the slider all to the right to 1.72Ghz. Test with your preferred benchmark then and notice the results (and displayed speed). The strange thing with those kernels is that CPU1 (second cpu) @ boottime will start with 1.728Ghz but after even one sleep cycle (cpu is offline) when awoke it will show the max of 1.512Ghz. So that may be a reason various benchmarks show incorrect value. The only way to force both cpus to work @ 1.728 is by using scripts in init.d that constantly monitor wakestates of the phone and force correct values. It's a workaround but it works :)
[HTC Sensation] sjh4:
thanks, tried that but system tuner pr still sees maximum as 1.5ghz
[HTC Sensation] JethroCl:
Both SetCPU and System Tuner Pro detect maximum 1,51GHz. Maybe a small error in the kernel...
[HTC Sensation] UnixSlayer:
Under both apps, [System Tuner Pro, and SetCPU] my speed is correct. Both CPU's running at 1.73. I am using the uv/oc 1.7ghz kernel.

I have 2 Sensations (one XE, the other is the standard model), both are running ARHD 6.1.1 ROM, Sense 3.6. I have flashed the 1.728_GHz_overclocked_and_undervolted_kernel_3.0.16-g9788208_by_SebastianFM ROM on both phones, but the XE still shows max overclock at 1.51GB. Even changing to Performance Governor using System Tuner Pro makes no difference on the XE.

Antutu Bench result for non-XE = CPU Freq 1728, Total score 6303

Antutu Bench result for XE = CPU Freq 1512, Total score 5391

[HTC Sensation] Snah001:
Yes it works very good with app callrecording.
[HTC Sensation] mat9v:
So it would seem that 1.78Ghz kernel works correctly only on standard Sensation.

Sebastian has to look @ it. I suppose when this kernel is used on Sensation XE it uses different frequency table, one that is not modded (although Sebastian flagged that kernel as working for both....)
[HTC Sensation] SebastianFM:
There are no errors in these kernels. I tested every modified kernel many times before I release it.

I'm using SystemPanel to monitor CPU frequency and adb shell "echo 1188000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq" to modify CPU frequency and it always works. Displayed CPU frequencies are always correct.

These kernels were configured and built by HTC. They have boot time perflock enabled. They could be incompatible with SetCPU, System Tuner Pro or other (I'll do some tests later).

I didn't change anything in these kernels that could cause issues.
[HTC Sensation] SebastianFM:
In my modified kernels is only one unified frequency table, but ...

Sorry, my mistake, when I was creating 1.728 GHz kernels, I didn't change CPU max frequency for HTC Sensation XE so it is set to 1.512 GHz because I left the previous value. I'll upload correct version of 1.728 GHz kernels soon.
[HTC Sensation] lightninbug:
Maybe you can clarify...is it BAD to keep a kernel such as 1.7 OC/UV on my sensation for DAILY USE? Im on latest Inserct Coin ICS and your 1.7 kernel...My phone has never been smoother, no reboots, FCs, etc....

One MAIN question I have is, If my phone ISN'T getting hot, NOR is battery...is it safe to keep it on my phone? Or will it eventually fry my cpu? Like from what this guy said..
[HTC Sensation] katdog75:
Hi there!

I am can't find the posts but I remember seeing someone mention a number of times that we can't use overclock controllers to adjust the kernel settings for Sebastian's kernel but I have been using CPU Master Pro (same makers as Antutu) and if I use this app my Antutu results mimic my adjust frequencies. (See pics where frequencies and results correspond) I don't know if the sleep, charge, overheat and low power profiles work but they seem to because last night when I was below the set threshold Antutu mimicked my frequency results for low power profile rather than the Max frequencies I have set as default.

Take care,

Kate

Having your phone on period will fry the CPU (eventually). But running the CPU faster decreases the life San of the chip. Also long as it's being cooled adequately, and isn't unstable, then no, you won't have any ill side effects. Your safe ( and by shorten life, nothing noticeable at all).

many thanks :)
[HTC Sensation] SebastianFM:
Clarify what? I didn't change one value by accident and 1.728 GHz works with proper frequency on HTC Sensation and with 1.512 GHz on HTC Sensation XE. I fixed it and I'm uploading now.

I never heard that someone burned HTC Sensation CPU using this frequency, so I think it is safe.

It seems SetCPU does not play well here. Try another app...

There is a button in antutu to overclock, it leads to market to a free overclocking app - try that one. On the other hand the antutu result you provided (5600-5800) is in line with 1.5Ghz cpu speed so I think the speed is set correctly even if it is not displayed.

Or maybe as Sebastian is trying to find out, the thermal protection is triggered, it looks like the 1.7Ghz result is lower than 1.5Ghz so it suggest downclocking due to temperature (1134 is default downclock value for thermal protection).

Weird, cause mine was pretty warm when I took the screen shots, I had just got done flashing three mods and phone had been rebooted 3-4 times the back was noticibly warm, (34C=93F). Have you tried SetCPU because with AnTuTu and SystemTuner Pro I had problems before. From my screens though system tuner was same as SetCPU.

Edit: When my phone gets hot it does reboot and wont stop till battery pull with 1.728 Kernel it does it a lot less with 1.5 Kernel and not at all with 1.2. Even on old firmware same thing.....

Phone really have to be COLD! If it is a little warmer (not hot, just warmer) then (probably kernel) goes automatic to lower frequency, in my case to 1134MHz.

[HTC Sensation] SebastianFM:
The scores are too low. I see on the screenshots that you installed app while running benchmark, prabably this caused low CPU scores.

HDR didn't work on stock kernel, probably it isn't related to kernel at all.

Thank you very much for huge donation.

Try to increase CPU temperature limits defined in /system/etc/thermald.conf.

1.512 GHz should be stable on any HTC Sensation because it is MSM8260 native speed. Maybe this is the solution:
[HTC Sensation] lindahl85:
Do you mean those?

The download icon is the notifier that the kernel has been downloaded already.

The mail icon is only a new unread mail.

The market icon is not downloading anything, i have disabled updates without wifi.

So the phone wasn´t doing anything.

BTW

Is it a kernel or rom issue that the red buttons is off on my XE?

The stock kernel from VI 3.0 and your 1.72 OC/UV did not help.

EDIT:

Fresh install of the 1.72 OC/UV. CPU is sett to 1134-1728mhz default

4min later without touching the phone, this is seen. CPU lowered to 1512mhz
[HTC Sensation] iba21:
is there a way to change the undervoltage by manually? as like a script or something else

i know stock kernel has about 1.250V @ 1.5ghz, so, i means we have 1,150V for undervoltage?

with ginger and modded kernel i could have a 1,075 V @ 1.56ghz stable frequency, is there a way to "put" that voltage in you kernel? maybe by manual editing? thank you so much ;)

The undervolted kernel does just that it allows your phone to run at a faster rate but undervolts to save battery.

@ Sebastian...Can you tell us how much the UV kernel is undervolted cause my phone handles UV but not too much? I installed the UV 1.728 kernel and got a lot of reboots...none with the 1.728 OC with no UV.

Thanks, missed that...

1.2 UV'd would still be cool. Going on a trip for a week and need all the juice I can spare. Will reinstall stock 1.2 before leaving, but UV'd 1.2 would come in handy I'm sure ;)

Underclocking the 1.7 UV'd with system tuner could work I guess, since it has the lower voltage table... Just not sure how well the Kernel and ICS are supported with the mixed reviews I've been seeing.
[HTC Sensation] Rickdaddy:
Just an update.

After taking a 30 minute shower (yes I like long showers) the phone seemed to have enough time to "cool down". Redid the benchmark test and it's now showing 1.7ghz. :D
[HTC Sensation] akapaul26:
The problem is your roms thermald conf file does not likely support OC kernels. Lets get some screen shots up of that file it's in system/etc. I'll bet that is why some of you have problems with the clock speed rolling back. I don't have the problem and I'm sure others don't either therefore it cant be a problem with the kernel.

[HTC Sensation] iba21:
the difference is the voltage of the cpu.. do you know all cpu has a running voltage? it needs to switch the transistors on/off, more frequency, more and more transistor's resistence (ohm), so, at hight frequency, cpu needs a lot of "volts" to have working transistors.. sure, more voltage, more power consuption

the undervoltage table put a less "volts number" on the cpu, it means, less power consuption.. if voltage is too bit, transistors can't switch, cpu freezes

so, an undervoltage table means less power consuption for THE SAME PERFORMANCE

it means, 1.5ghz at 1Volt has the same performance as 1.5ghz at 1.2Volt..

the trick is to change the table voltage to have the maximum performance at minimum power consuption..

Oh, not all chips are the same, not all can be undervolted so much, it's a building factor, maybe the machine uses better silicium, new utilities, etc etc..

the stock table tension has the right value as all chip can run without freezes

my chip works at last at 1.075Volt @ 1.56ghz STABLE

stock voltage is at about 1.250 @ 1.56ghz

your can be a better or a worst one than mine, you'd try to undervolt manually (you can't for now with ics kernel)

Any plans for a 1.5Ghz undervolted kernel?

1.7 is overkill in my opinion, with no huge performance gains, so 1.5 undervolted would be ideal :)
