Overclock causes WLOD? - XPERIA X10 Q&A, Help & Troubleshooting

I don't consider myself a noob when it comes to flashing ROMs, I've been using xRecovery and Flashtool for some time now.
I have looked around XDA but can't find anything relating to my problem, if I have missed it please tell me and close this thread.
I have unlocked my bootloader using the_lasers SEMC CMD, I've flashed Doomlord's v5 Kernel and before that v4 with overclock but every time I try to overclock my X10 I get a WLOD?
Yes I know there was a warning in Doom's thread that the kernel my not work on all X10's but the warning stated that the device may not boot, no mention of WLOD?
I have tried both SetCPU and CPU Master to overclock but this always happens.
Is it me, am I doing something wrong? Making a noob mistake?
Or is this my X10 and a compatibility issue with Doom's kernel?
Any advice would be greatly appreciated!
Thanks for looking, JayJ.
EDIT- Just to add I'm currently using Wolf's TW v5c but have also tried this on Z's CM7 with Doom's kernel.
Had no problems overclocking with the zKernel!
Swyped on my WB TW Gingerbread v5c X10i

Yes, overclocking can cause WLOD's. Either because your chip-set can't handle high frequencies or too much/not enough voltage is being supplied.
I, having quite a new x10 can handle overclock quite well. However, due to the default voltages that Doom has set in his kernel, my phone does tend to lag at high frequencies. I fixed this by modifying the init.d file that controls the voltages and set the high frequency voltages slightly higher.
What you could try, is download an app called "Incredicontrol" and experiment. Fist set the high frequency (MHz +) voltages up by 0.0025 each. Reboot, overclock a little, test, if it needs more, do it again, but be careful. Increasing the voltage by too much will most likely cook your CPU and render your phone useless. In other words, be gentle. Also try reducing the voltage to see if that works.
If that doesn't work, you most likely have the temperamental chip-set of death which is practically incapable of performing as a phone should.
Hope you can find something that works for you.

Thanks for the great reply, very informative and helpful. Appreciated!
My X10 is quite old now, I've had it pretty much since release. Also I always thought my CPU may have had issues because my CPU regularly maxes out and freezes the phone up, not so much since 2.3 but was a nightmare on1.6 & 2.1.

Yes and no, the overclock itself can't cause wlod as far as I know, but what can cause it:
Fast overheat due to high temperatures, clock too high + voltage too high + high external or high battery temperature.
Defects on the processor.
The thing is, if you are on Doom's kernel and yet you can't overclock it past 1ghz try increasing the voltage a bit up to 25mv or 50mv on each freq at a time until you reach the correct freq/voltage.
At start my phone couldn't handle 1228 now it can using correct voltage settings(1400mv in my case)

[Q] Enlightenment on Undervolt for WB 4.0.3

Hello guys
I'd like some help on installing the Undervolt for WB's 4.0.3 ROM
I'm on 4.0.3 stock kernel. All I have to do is flash the Undervolt addon and Ill be good or do I need other apps like CPU Master after flashing it?
I know theres a lot about it in the topic but its all untied and confusing
If someone could take some time to explain to me how it works I'll be really thankful.
dnt have wb rom but in general I believe ud update with the file provided n I believe u would need either set cpu or cpu master to be able to adjust the minimum value to the lowest 1 possible
Sent via xda using cyanogenZmod running Enigma v2.3 on Xperia x10
So whats the difference between having just cpu master and setting it to the minimun and doing the same with the UV?

Hi,
for undervolting you do not need an additional app.

I want to understand the difference between just setting the CPU speed with an app like CPU master and setting it with undervolt flashed
Could someone please explain?
i flashed the stock kernel first but there was no option to 128mhz also i believe uv works without app...you can also flash the custom kernel and choose the least frQ as i did. i also have enlightment but don't know is that from overclocking to 1113mhz or from the minimum 128mhz or from the undervolt itself??

I think overclock/underclock is different from undervolt, no?
Hi,
underclock = reduce frequency = gain life
overclock = increase frequency = loose life = gain speed
undervoltage = reduce voltage for certain frequencies = gain life
With good settings for undervoltage and underclocking you can gain a lot of extra batterie life.

Under and overclocking changes the speed at which the cpu works.
Less speed means it doesnt work as hard so saves battery.
More speed means it works harder so needs more power so reduces battery life.
At the different speeds the cpu works at it uses different voltages from the battery, less speed needs less voltage, as the speed increases it pulls more volts from the battery.
The voltages it uses are controlled by the kernel.
The undervolt module changes the default voltages each speed uses so in effect a higher cpu speed can work at a lower voltage so it improves performance at no cost to the battery life.
However, if the new voltages are too low the cpu doesnt have enough power to run so you WLOD.
The UV module (and custom kernels) have been tested on loads of devices and generally are stable, however, reading the threads suggest that some phones are still vulnerable to the occasional WLOD using these modules...
Just try and see what is stable for you...

It seems to change from phone to phone because the chips inside are not all exactly the same.
They are tested to conform with stock speeds and voltages but can become unstable when changing these.
Some phones (Luckily mine included) can handle 128 - 1113 Mhz with ony a few (Very rare, about 2 a week) WLOD's while other people say their phones WLOD constantly with any change.
The best way is to apply the mod you want and check.
I seem to remember that the UV and the UC/OC modules are not compatble on WB's ROM, you have to choose what you want.
However, I am running freekernel 4.05 which allows me to use UV and then configure which speeds to run via SetCPU.apk.
If you install a kernel there is no need to apply the UV or OC/UC modules..
Read DooMLoRD's custom kernel thread, he has a lot of good info and useful tips on how to test which is best for your phone.
exactly, wolfbreak also mentioned in his thread about the incompatibility of overclock and undervolt with some devices.
unfortunately i'm at the short list of devices that can't handle both, for users like me he gave the option for stock kernel with optional undervolt, which i'm using now with no problems.
Thx for all the info guys! Now ill try the undervolt
I have one more question: everytime that i flash a update on the ROM i need to reflash Undervolt?

[Q] Over Clocking Kernels

Samsung Fascinate CDMA
Rooted MIUI 1.9.16
Did a brief search here looking to understand how to operate overclocking kernals, but find it/me relatively limited.
I have installed and ran Glitch v11 and v12, played around with HL to LL, and made adjustments to undervoltage utilizing Pimp My CPU and Voltage Control. I have also ran Tweak (though not really a kernal).
My question is this,
am I overclocking when I reduce voltage on Mhz's above 1,000?
If not, could someone point me to, or explain how to achieve overclocking on our phones, and
which kernel and governor do you prefer for overclocking?
As an ammended note, I've installed Tegrak Overclock, but am still looking for a user guide...
Thank you for your time.
If you're the running the glitch kernel...use voltage control, not tegrak overclock...over clocking is when you turn the CPU speed above its normal speed..anything over 1GHz.
under volting is when you turn down the voltage frequency to achieve better battery life...
Any one clock speed may perform more or less stable with different under volting unfortunately all of our phones will vary in performance so one setting that works for one may not be the best for another so experimentation is really the best option...this applies for schedulers and governors as well.
I personally overclock as high as I can until it freezes or crashes..then I go 1 setting down...I then try undervolting different steps observing the stability of my phone...when I find what I like,I run it for a few days, then if its still nice and stable I will apply on boot.
The different leakage values are affected by the hardware quality of the chips in our phones which also vary..I start with high and see how high I can overclock..note the setting, then try medium..see how high I can overclock and so on...just as a reference..high leakage creates the most heat and is the least efficient, but works for most phones, while low leakage is the most efficient and generates the least heat and will work with not as many phones

How do you over-clock using Glitch and Voltage Control? I see that Voltage Control goes up to 1,300Mhz, but it's at 0 above 1,000Mhz and can be dropped down to -200mV. Is overclocking just the process of decreasing that voltage on Mhz's above 1,000Mhz's

come on man.. Clock speed (mhz) and undervolting are 2 completely different things.. Forget the voltage.. No changing the voltage is NOT overclocking.. You overclock by changing your maximum clock above 1000mhz which is stock for this phone.. Try long pressing 1200mhz and selecting set as max.. Now your overclocked to 1200mhz..
Sent from the fascinate that holds the record benchmark on antutu
No decreasing the voltage is simply undervolting whether it's over 1000 or under. The idea behind undervolting is increasing battery life, but you can't necessarily go and set each level to the maximum undervolt (200) you half to see what works. Increasing the processor speed is overclocking, stock speed is 1000 so anything over that is over clocked. As far as how far as how far you can over clock depends mostly on 2 things, 1. the kernel your using, ( for example if it shows 1300 in the list that means thats all that specific kernel supports) 2. It varys greatly between phones. For example with glitch you can overclock to 1700 but very few phones can run that high for longer than a few minutes!
Hope that helps.
Sent from my SCH-I500 using xda premium
Yes.. And the fact you say your running glitch and your max oc is only 1300 my guess is you broke your kernel with tegrak overclocks module.. Delete tegrak and stop downloading overclock apps. or any other root app unless you know fully the consequences first.. If after deleting tegrak, and rebooting, if your voltage control don't show a maximum clock of 1700 mhz, then you will need to reflash your glitch kernel

Neh4pres,
Yeah, I kind of feel like a heel. For some reason, I had a brain fart when looking in the 'General' section of Voltage Control. I see now how to overclock.
Regarding ost #6:
When I flashed MIUI 1.9.16, I did not install any kernel; so it was kind of a half truth in that while running 1.9.9 I did have Glitch installd. Nevertheless, I still have Voltage Control installed.
mkropf,
I see that now, and thought as such earlier, but needed some clarification.
Having so many issues with Glitch and 1.9.9, I'm hesitant to install Glitch, but interested to see if it runs better on the newer MIUI...

You wouldn't want to use my voltages, I put everything way lower than anybody else does or recommends and am just lucky that it is stable for me but it causes the sleep of death for anyone else.
For comparison, just run JT's kernel for a bit and then flash glitch and try it... once you play with OC/UV and voodoo color you won't be able to go back. (you'll be able to but you'd have to be insane.)

Edit 1- I am using SetCPU to OC.
"overclock" and "safe" cannot be use in the same sentence, it just wrong.
theres no safe overclocking. moreover each and every device is unique even for the same model.
what is working with others doesnt guarantee it'll works with yours.

I know you might think what I'm going to write is unnecessary and going to contradict with your believes here. but I'm going say it anyway.
If you are going to use your device for a long time then I would suggest not to overclock too much. You'll know when something will go wrong with your over-clocking. Your SGA would start rebooting randomly. Heating up would be excessively common once you start overclocking, using your SGA while it's charging. Over clocking will definitely reduce your processor life span. People who do can over clock their device to get the max out of their device and know they're going to change the device in sometime later anyway.

Don't worry! Like I said, I have experience O/C'ing processors etc and I know how bad the effects can be! I am not going for a massive overclock at all. Just a tiny bump in the speed. At the moment, I am running 825mhz and already the speed has improved dramatically. I may go a little further but 902mhz is a bit mental for my liking.

[Solution] Solving Doom Kernel Reboots!

I found a solution to fix the Doom kernel reboots for those who are unable to download stock roms from HTC (Rogers Customers). Requires CWM Recovery.
1. Download stock kernel here - http://www.box.com/s/7dc3bf2adc9e2f05b717
2. Unzip archive
3. Move Zip file to SD card
4. Reboot into bootloader fastboot reboot-bootloader
5. Flash the img file fastboot flash boot name.img
6. Go into CWM and install the zip.
This solved my problem, hopefully it works for you guys too.
This should work on ALL devices not just Rogers
it doesn't actually solve the kernel issues...
your just replacing him.
i still think his kernel has a lot more potential than the stock.
It fixed my issue.
I care more about having a functional tablet than a kernel that may have more potential but is buggy as hell.
i agree. and i'm running the stock as well.. just wished the doomlord one would work as well.
Hi there,
Noob user here.
I got HTC JetStream from previous owner with doomlord Kernel on it.
Tablet is constantly crashing for no logical reason which leads me to believe that the kernel is causing this issue.
I would like to flash back to the stock kernel only as my device (Rogers) is running a stock image.
I am having difficulties to follow your instructions.
Wold somebody be so kind to post more detailed process steps to complete this kernel flashing back to stock.
Thank you very much.
I had the same random reboots using Doom's kernel until i overclocked it to the maximum. It's been almost 2 weeks since i experienced any reboots....

could you be more specific?

If I find some time this weekend, I'll try maxing out the O/C though and see how it goes, as I do find the DooM kernel snappier, even at stock speeds.

You do realize that by doing that you are running your kernel at max speed constantly which means additional heat, stress and wear on all systems?

No, it won't run at max speed constantly unless I set the governor to "performance" mode. In "interactive" mode, which I believe is the default, it will still clock the CPU at its minimum value until the tablet needs more CPU resources, such as when scrolling, loading a webpage, playing a game, etc.
But yes, I'm aware of the risks of overclocking. I've overclocked every HTC device I've had very few problems (my One XL has exhibited some bootloops, so I've stopped O/C'ing it.)

I'm running 1.83 ghz ondemand with also the lowest setting for the min freq setting. I will increase it to 1.944ghz ondemand as the max setting and increase my min setting to 756Mhz on deadline, and see if the reboots stop, otherwise I will have to install the stock kernal.
I am just wondering if I install the stock kernel on top of my OziMood rom, if this will cause Rom problems?
Any thoughts on this?

I have mine on max: 1.62 ghz , min: 594 onDemand and it hasn't crashed in two or three days. So we'll see. Now to answer your question, if you want to flash back to stock on that Rom you'll have to install the stock WiFi modules from recovery. After that everything should work normally.

Thanks for that.
So far, I haven't had anymore reboots.
Increasing the minimum seems helpful.
I get plenty of battery life, so I am really happy about this for now.
Just a quick update.
I've been running 1.944 GHz as my high setting and 756 GHz as my low setting for some time now and I have to say, no reboots, no lag, super fast and stable.

Nice, I'll try those frequencies on mine. Thanks for sharing.

[Q] Flyer Overclocking Help

Flyer is running Senseless v4 HC 3.2.1 rom (based off Virtuous Rom) and it is fairly smooth but would like to try and speed it up as fast as possible and still remain stable.
Question #1: The rom is packaged with an HTC kernel (assuming stock). Is this capable of being overclocked or do I need a custom kernel such as Leedroid?
Question #2: If/when I get the proper kernel to allow overclocking does anyone want to share their SetCPU settings? Or recommend a different way to overclock?
Because of the age of this device just want to milk every last bit of speed from it until it dies.
A month and no reply. *BUMP*
I am now on oc 1.86/384 smartass v2 leedroid kernel. Going well ve not experience kernel panic and no overheating. Have not tried any higher as this is good enough. Cheers

1) Stock kernel will not allow you to overclock, you need a custom kernel.
2) Every individual device and processor is different. By definition, another person's CPU may be capable of certain overclock speeds, where yours will not (or vice versa). For that reason, another person's SetCPU settings aren't going to do you much good. Just start stepping up the CPU clock a bit at a time, and use the device for a while and see if it functions properly with no errors. Just like overclocking anything else.

Thanks for the reply.
Problem now is it looks as though the rom I have currently is packaged with the a stock HTC kernel. Cannot find a working link to either Leedroid's HC kernel or any other custom kernels.
**EDIT...NM, link is working now. Go figure**
