Hey all! I'm new to the TF, but not to Android - been messing around on my Droid X for a long time now. Anyway, I had a question about overclocking - I can't seem to clock my TF beyond 1.2 or so without it rebooting. I'm running Revolver 2.5.1 and Clemsyn v10, since v13 wouldn't let me OC stably at all. Using SetCpu or CpuMaster. I've tried undervolting as well but with the same results. The only reason I ask is because I don't really see anyone else reporting this, so I was wondering if I'm doing something wrong.
Any ideas?
like you said you have to look at the voltages, however not all devices can handle the same cpu speed it can be that your cpu is just not powerfull enough where other TFs can go a lot higher, you just have to be lucky I guess
I actually ended up trying Netformer and Prime together after a fresh nvflash, and on that kernel I can OC to 1.4 with no problems. Think I'll stick with that setup for now.
Thanks for the input, anyway!

I have been looking for a couple of days, and I can't seem to find my answer anywhere. Sorry if this question has already been asked. Does the Tiamat Kernel come overclock already, or do you need to use an app like SetCPU?
SetCPU is needed
Thank Brenardo.
I really want to root so i can get the USB host, and SD card. I just didn't want the overclock. I was told that Tiamat was overclock from the get go.

If you do not run an overclock program, the stock max is still on the CPU.

Do you know what the set Max is on the tiamat kernel?

even without an OC app running my CPU sometimes runs up to 1504mhz. I've tried every kernel since the first tiamat one. I have a Canadian xoom rooted with one click. I'm using tiamat 1.4.1 and the issue isn't fixed. I've read many others experiencing the same issue. I've tried using setcpu and Droid OC to limit it to 1ghz but it still hits 1504. There both uninstalled now but I'm still having spikes. Just my 2 cents not trying to hyjack your thread. But if anyone has any input as to whats happening I'd appreciate it.
Also my battery life is significantly shorter since rooting. From about 9 hours to 4 now.
Any suggestions ?

How are you seeing its over with no app? I'm not calling you a liar, just trying to get all the facts. In all test we have done, even with the setcpu oc to 1.5/1.5, we actually see the cpu running at 1 ghz after a wakeup.

I'm watching the temp+CPU widget to monitor what's happening. Are you suggesting its giving inaccurate readings? Setcpu at 1ghz would still show random spikes to 1504mhz. I don't have any OC tools installed right now but my widget still shows it hitting 1504 especially under load. I was thinking of returning to stock and rooting manually but it not a huge problem just strange. I was hoping the new kernel would fix it but its still happening. Is there anything I can do besides start from scratch?

Yea setcpu is not 100% yet. Does your widget show both cpus? What we were testing was the second CPU. After you xoom goes to sleep, the second CPU is never set again by setcpu (known bug). So lets say you are running 1.0/1.5. After you xoom goes to sleep you will wake up with cpu 0 at a max of 1.5, but cpu 1 will have a max of 1.0. The info i gave earlier was said wrong. I was actually looking at the wrong line, so you may in fact be correct on the 1.5ghz random jump . Gonna stop talking now, as we are hyjacking someone else's thread .
In theory, you should not need overclocking software, as the max is set at 1ghz on both cpus. But as said above by Bandit504, this may NOT be the case .
Thanks bwcorvus and Bandit504 . So I guess to call it is safe, it would be good idea to use SetCPU, or Droid Overclock and have the maximum set to 1 ghz, to keep the proc from hitting the 1.5 ghz speed. I just hate to ruin the hardware with the overclock, and have to drop another $600 for another xoom.
Hi all,
I've been having random reboots/freeze-ups ever since I rooted.
This happens regardless of whether I am OC'ed or at 1ghz. These reboots tend to happen when watching Youtube or when browsing.
Would just like to have a feel of the ground if any of you who are rooted experiencing this?
Maybe we can start off by stating the following:
Kernel:
Clock Speed:
OC app: Setcpu or Droid OC
Governor setting: Interactive, on-demand etc..
Last app you were in that caused reboot:
For me, I am on the following:
Kernel: Tiamat 1.41
Clock Speed: 1ghz or 1.2 ghz
OC app: Setcpu
Governor setting: Interactive
Last app you were in that caused reboot: Youtube, browser
Im not sure if this thread shld belong here but since this is Dev where most of us root and OC, I thought I'd ask it here and hopefully we spot some trends with regard to the reboots.
Pls dun flame me Thanks!

Moved to Q&A.
I have the same issue - Canada WIFI version
same problem, Canadian WiFi Version.
Not sure if it's because I flashed 1.4.0 then flash 1.4.1 to get the external sd card to show up. But I noticed after I got the external sd card to work, my usbOTG started working too, but from what I've read that should have been removed in 1.4.1 for stability issues.
Same issue. Using the tiamat kernel. It happens with different apps so its not any one for me.
Sent from my Xoom using XDA App
Switch to Droid oc and delete setcpu. Worked for me. Interactive. On demand is junk on Xoom. I use on demand on DroidX.
The kernel will Max to 1504 causing reboot (on some Xooms). Some device can't handle 1504, mine included. Superuser will throw up an occasional user permission for Droid oc as it brings the MHz back down to user setting.
I was experiencing random reboots with the same kernel, mostly just browsing in Dolphin HD. I first stopped OC in setcpu but the reboots still occurred. Then I uninstalled/reinstalled Flash 10.2 and cleared Dolphin's data.
So far, it seems to be much more stable and even battery usage has toned down.
This shouldn't have been moved to Q&A. There is enough discussion at this point on this exact topic that it needs to be addressed. There is a serious problem with the over clock in the tiamat kernel and/or the software that is supposed to govern the overclock. The developers here work very hard for all of us to get the most out of our devices and I fully support them in their work, but we are putting ourselves at risk. It is my understanding that SETCPU and Droid Overclock are only able to govern One of the Dual Core processors while the other is overclocked all the time. There is a widget in the Marketplace (Temp+CPU V2) that will enable you to monitor your clock speeds.... See for yourself.

I installed temp+CPU and don't see two cores. Only one display for MHz and it cycles from 216 to 1200. Is there a screen I'm missing?

This is right where it should be... Development forum is for developing...Discussing does not go there unless its in a thread where something was developed...The tiamat crew knows all about it...they did not make the overclocking, they used someone elses, and are about to remove out. And yes you are correct on the 2nd core.

Remove it? So no more overclocking? Can't a ROM allow OC and voltage control? But I guess it always comes back to the lack of source code.

Kernel source is available. It's the rest of Honeycomb that isn't.
So what is the best resolution to the problem? I get at least 5-6 reboots a day...I dl'ed Droid OC and deleted setcpu.
I had a harder time getting it to reboot with Droid OC so I think that's your best solution for now.

This is probably the best thing to do. If you think about it; Can't be good if your device is rebooting all the time, plus it's just too annoying.

Ok, sorry if this seems like a stupid question but... I have flashed/tested all of the Tiamat Kernels onto my xoom and it seems that I can only run the 1.4 Ghz Kernel with no random reboots. So I thought that if i download the higher 1.5Ghz or the 1.6Ghz and just under-clock it to 1.4Ghz that should stop it from doing random reboots, but sadly it doesnt and I still get random reboots even with Setcpu Under-clocking it to 1.4Ghz. Now is this typical or am I missing or misunderstanding something? Is there a reason why I cant use the higher Kernels and Under-clock them to 1.4Ghz and get no random reboots? I am only asking because I flashed the Riptide and under-clocked it to 1.4Ghz and it really made my xoom feel much faster and nicer in my hands and would love to keep using the Riptide Kernel.
Thanks in advance,
-Dez
I have the same issues and have been wondering the same thing.
I have similar , with 1.6 with ums
only flashed to get ums , and had a few crash/reboots for the first time since i bought my xoom about a month ago.
what i could do with is a stock speed kernal with all the bells on !

I too have noticed this, after reading your post I tried keeping the Kernels but with no OC and left it at 1.0Ghz and it still has random reboots. So is there something in the Higher Kernels that are causing it to be unstable regardless of what Ghz you clock it to?
watch setcpu at times. It doesn't matter what you set the clock at in setcpu it will still go to the max clock the kernel allows. I am not sure if it is a bug with setcpu or if it is just the way the kernel works. If you reboot your Xoom when setcpu is at 1ghz, then go and play with the xoom after reboot for awhile. Go back into setcpu and look under the info tab. You will see that the cpu has indeed been running the higher clocks then 1ghz at times. It doesn't run those higher clocks much but it does. Which is most likely why you are getting lockups or reboots. My Xoom seems to love the 1.5ghz kernel but hates the 1.6ghz one.
Funny I was on the same boat. Started out with 1.6...reboots. went to 1.4 no problems. Tried riptide. Got app force closes. Now on 1.5...stable once again. The thing is im not even using OC on any of them

I have a US Wifi Xoom and I recently flashed a AOSP OC Kernel and I'm scared that my Xoom will mess up. Today I unplugged my Xoom and it shut off by itself. I couldn't turn it back on the normal way. I had to hold volume up and power. I have a feeling its kernel related since I flashed it last night. Thanks.
For the US WIFI Xoom, follow the instructions on this thread to return to stock:
USA WIFI 3.1 Stock:
http://forum.xda-developers.com/showthread.php?t=1080963
Pretty straight forward.
Just out of curiosity, which OC kernel did you use? If you're pushing to 1.6GHz, it may not be as stable as others. There are others - 1.5GHz and 1.4GHz that you can try for more stability.
Tiamat's 1.4.2 Kernels:
http://forum.xda-developers.com/showthread.php?t=978013
Keep in mind though, these kernels are tested rigorously before deployment, so unless you decide to mess with the files themselves, you shouldn't inflict any harm on your XOOM with these Kernels.
I did the 1.5 kernel and I just found it weird because I saw a thread today about someone's Xoom not turning on.

Hello,
Is that possible to have an added kernel to theTiamat list: one without any OC?
Battery consumption is a big concern for me...
Sorry for the post in here but I'm still limited to Q&A on XDA.
You don't have to overclock even though you flashed an oc kernal. I have 1.6 oc and I don't oc at all.
Is there an option to turn off overclock or is the kernel supposed to work with SetCPU or another OC app?
If OC isn't set as default then that's a good thing because I don't see any advantage to overclocking the Xoom.
It was a scare and I don't want it to happen again. Is prefer the stock kernel to avoid any problems.
Sent from my PC36100 using XDA App
The OC isnt set by default. It is still set to the default 1GHz.
The kernel just allows you to overclock to 1.6GHz if you wish.
I had another weird reboot yesterday. The last thing I flashed was the kernel.
Might do that sometimes. Might be whatever you were doing. Or the xoom isn't used to the kernal, or just plain don't like it.
OK so I've noticed quite a bit of lag on the device so I'm trying to clock it up a bit. I'm a ready rooted and on the krakd 1.4.2 rom... I'm trying to use the no-frills CPU manager and I want to know how to use it without screwing up the tablet

Umm.. You're running at 216mhz.. the normal is 1000mhz.. Haha you cant really mess up your transformer, if you undervolt or overclock too much, the device will just reset itself (if you didn't set it to apply at boot) Im running at 1680mhz as I type this..

Yea I noticed the 200mhz thing when I first started the app
OK thanks for the answer
Er, it IS possible to burn out the device, don't spread bad advice. Most of the kernels will give you a safer range (less than 1000 for the super safe, less than 16xx for the OC kernel).
