Underclocking LT15i - Xperia Arc General

Hello,,
I am runnig FXP CM9.0 on my Xperia Arc.
When i want to undervolt with my android freezes im still get max undervolt -25mv
And with Acronium with can go far as -75mv
What is the problem?
Thnx in advance

correct me if im wrong,as far as i know fxp kernel doesnt support uv..
from my ARC using I.See.Ass

I also think it does not support, but I think you should install another system in the arc to get more performance and less battery drain ... CM9 still has many bugs ...

[Q] overclock 1.7Ghz?

Can someone please make 1.7Ghz possible. My phone crashes every time when i oc to 1.8Ghz.
Im just interested in what my phone is really capable of.
try cm7 with franco kernel, perfect with 1.8 oc
Already tried that. Freezes on my phone.

I've seen somewhere that changing the I/O Scheduler to vr helps OC to 1.8GHz. I haven't tested it, and I don't know how much this affects the phone.
I just got my root on a few days ago. Before and after games play fine at the stock 1024mhz so I think overclock xperia really wouldnt mean much besides less battery life. Plus quad cores are early to mid 2012 ... hopefully something like the xperia play only jacked on steroids comes out next year. I honestly havent looked around enough tho I hope xperia play isnt the first and last of its kind!

I have tried the vr also no effect...
it's works on my phone !but seems not good,sometimes automatic reboot,the rom is oxygen r3. just this rom can only works on 1.8Ghz !

sorry for my english

Undervolting and you, share your settings

Switched to CM9 last night and I want to Undervolt it to get the max out of the battery.
Plz share your Undervolting experience, which rom, kernel, settings, ect'...
I imagine it will help more people and not just me

For now UV is only possible with GB kernels, the ones built from Sammy's source code, and I don't think there's anyone left with gb so this question is pointless for now until we'll get the ICS source code from Sammy

Screw that last guy who thinks he knows jacks ass, use your favourite app to change cpu settings or terminal console to change both cpu gpu, assuming ur using the cm9 experimental builds with the kernel included.
And my shared settings to u are:
CPU
1400 - 1175
1200 - 1125
1000 - 1075
800 - 1025
500 - 950
200 - 925
GPU
400 - 1050000
267 - 875000
200 - 825000
And if u know under and overvolting, its pain in the ass to find the right settings which works for u, overheating issues for me are greatly reduced by undervolting.

Watch you language little a*hole
Cm9 and stunner with all respect have some bugs to use as daily rom ( speaker, otg, ums) and a proper kernel can't be delivered yet until source code is out from Sammy, I bought my note for a reason and it is certainly not to have an oversized GNexus!
Next time think a bit before you comment,
I just gave my opinion for UV with experimental kernel since many hardbricks due to playing with kernels is going on right now, and I know that UV can't cause a brick but the kernel might!
So I prefer a GNote kernel, made from a gnote source code even if it means waiting for it a bit longer, than a kernel made from sgs2 source code .

This is not true.
Also, be careful with the official ICS ROM. It has the eMMC bug which can "superbrick" your Note, which requires a motherboard swap to fix. I'll be using CM9, which is safe.

Everything on earth contains the "superbrick" bug... that is, if you were previously on CM9....
NOTE, USE UR OWN VALUES. Applies to cm9 experimental builds with supplied kernel.
If u know how to use terminal console or adb, u can do:
For voltage:
echo "825000 875000 1050000" > /sys/devices/virtual/misc/gpu_voltage_control/gpu_control
For frequencies:
echo "200 266 400" > /sys/devices/virtual/misc/gpu_clock_control/gpu_control

Guess I didn't explain myself the way I wanted, no harm done
Most of the time I use speaker when driving which is missing in CM9
So I'm forced to use official rom

I haven't heard of anyone bricking because of xplodwild's CM9. If you mean chasmodo, that was most likely because he wiped on the LPY kernel.

show me one person who has bricked their phone, who has not first used CM9 or some derivative... I believe that all of these hard bricks are being triggered by CM9 in some way.

You're the one making the claim here, why don't you get some evidence to back it up?
It's quite an extraordinary claim, and I'd be more inclined to believe Entropy512's take on the matter (eMMC bug in leaked kernels) because he's a kernel dev.

NEXUS S and the overclock

Hi guys,
I have a problem with my nexus s (i9023).
I've pretty much tried all the ROMs available on XDA. Every time I try to do with any overclocking kernel, but after some use the phone crashes and restarts.
The processor of the nexus s does not support overclocks?
FYI over clocking does cause your phone to restart or crash

Increase your voltage.

Yeah ... My i9023 also can handle 1200 with matrix without raising voltages and with no reboot whatsoever .
Unfortunately for us (and really nice for him, because he moved to N4 ) .. The matrix is discontinued..
Ps: check out the kernel in the hellybean thread . it has live oc working as well. :thumbup:

For some reason my phone (also i9023) can only handle 1320mhz OC.
Other steps (1200, 1400, 1096, etc..) cause reboots.
Try using matrix cfs then OC to 1320mhz.
Or marmite 7.2.1, increase all voltages by +25mv then OC to 1320mhz.

Please point me to the Nexus S discontinuing..
My phone easily handles 1200mhz... 1320mhz works well too but under heavy load I'll get a reboot... 1400mhz def needs raised voltages... I've clocked that high before but I don't think the phone runs as smooth at that setting... Might be too much for the processor... This was using various kernels... Currently on Matr1x CFS 24.0 cm @ 1200mhz running fine!

Try trinity kernel also. I could go upto 1.4ghz with ease in that.

Some kernels are undervolted... So it makes it less stable... I'm on cm10.1 right now with the included kernel and it seems to be running at 1400MHz just fine...

I use marmite 7.2 but still no could not find a way to make it stable @ 1096mhz .. I just need the GPU clock to be stable so that I get a smooth gaming experience as well . Plus I cant revert back to matrix as its JB 4.1.1/4.1.2 and not 4.2.1 ... Anyone was able to make a i9023 stable @ 1096mhz ??

I'm more or less stable at 1096 running BB6 ROM and marmite 7.2. Sometimes it gets slow with heavy usage and needs a reboot.

Same with my i9023, 1320mhz works great on my setup of CM 10,1, Matrix 7.2.3 kernel. Stock voltages.
I've been trying for a long time to find truly stable voltages for either 1096 (marmite) or 1200 (air kernel), but irrespective of my mVs I can never get beyond two days of uptime before I experience a freeze. All overclocks seem to work at the default volts set by each developer but there's this latent instability I can't do anything about. Starting to think this is just the nature of the beast and very few NS users actually have CPUs capable of long-term OC stability.
Still, a few extra FPS in the launcher and a slightly smoother Temple Run probably don't justify an OC anyway.
i use marmite overclock 1-2 days ...all ok here
I can run [email protected] for as long as I want. Even 1320 with 25 volts increased. Never had issues.
Sent from my Nexus S
Well dang.
Maybe I just have an anaemic ARM chip.
That being said, I've really only ever experienced the symptoms of an unstable overclock when my battery's been close to empty. I suppose that might cause the voltage to dip and my phone to freeze. Might try 1096 again using 7.3.

SentinelROM v4.50-CM10.1 kernel discussion.

I make this thread Instead of having a constant discussion about kernels in the SentinelROM v4.50-CM10.1 thread.
This: http://forum.xda-developers.com/show....php?t=2037363
So when someone ask about kernel in that thread, just link this.
Sentinel196 works hard on his rom and kernel, so why do you change kernel and what kernel did you change to?
What settings do you use?
What app do you use?
Do you play games?
Are you a casual user?
Other?
I´m new to this rom so i´m going to try it completely untouched for at least a week before changing anything.
So that i get a good feel for the performance and battery.
These are good for battery life.

Guys can someone confirm if they can get most wanted to work properly without crashing and also real racing 3
?
Kept crashing on me
Rush85 v4 and v5 worked on other games like nova3 etc.
Sentinel kernel that came with rom gave me artificacts and crashes on games
If these issues are fixed then I would definitely want to come back to sentinel rom

N.O.V.A 3 crash with Cyanogen Mod 10.1 and Dorimanx 9.17 , time to try with Sentinel
Used Stock Sentinel Kernel for a while (with Performance governor, i really don't care bout battery ) & felt phone smooth.
Changed to Siyah v4 by Rush ( Curiosity, u see ) & overclocked to 1.4Ghz with Conservative coz for some reason, conservative gave more smoothness than performance .. & phone never felt more smooth :fingers-crossed:
& oh yeah, post 3-4 charging cycles, m gettin 4.5+ hours of screen time with WiFi on most of the time. So m gonna stick to siyah & sentinel for a looong loong time

The latest build of SlimBean (5.5-WEEKLY) is very good. With her, I reached more or less 3800 points in Quadrant Standard.
With the Sentinel, I reached around 3100-3300 points.
With Sentinel + Slim Kernel I reached around 3400-3500 points, even that little thing, already demonstrates some improvement.:good:
@thiagox
Ah, you are talking about benchmark.
Whats that got to do with stability and smoothness?
Stability is no fc, no reboots, no hangs.
Smoothness is an overall performance with no lagg/stuttering.

you will need to unlock bootloader>instal new karnel that support over clocking> then overclock your phone
This is as easy as possible but in reality this is so hard, actually I am not sure if there is any karnel that support overclocking. Why do you need to overclock your Z1, you won't notice much performance boost, but you will drain your battery alot faster, most people underclock their Z1 to get better battery life
@BKL SONY Z1 You can't open 2 identical threads on different sections. One of this 2 will be closed!
