[Q] Do you need a specific kernel for overclocking?

I have Virtuous 2.0 and it works fine with 1GHz in SetCPU, but if I set it to 1.5GHz and try to do anything it just crashes, then reboots
I just tried it now, have 800MHz set, but the phone was in off mode doing nothing, so turned it on, set it to 1.5GHz max, then opened up a game (Crazy Snowboard) and it loaded, then as I started the game, it counted down from 3 to 2, then froze and rebooted after a few seconds
Then, when it rebooted, I opened SetCPU and it was still set to 1.5GHz, but SetCPU said 1GHz max
Oh, and I never flashed another kernel by the way (don't know how on this phone), so was the kernel installed along with Virtuous (didn't know that was possible)?

If you want to overclock to 1.5 ghz, you need a better kernel that allows overclocking to thats speeds. Try unity v4 kernel. It allows oc up to 1.7ghz. The link is in my signature. You can just flash the kernel right over without any problems. Hope this helps

different kernels offer different things. You'll find one that you like and works with your ROM. Just as an FYI, not every kernel/ROM combo will be stable at 1.5ghz. That's a big overclock for a processor that is normally at 806mhz. Keep in mind you should use screen off and temperature SetCPU profiles to keep it in check.

[Q] CPU not using any speed other than max.

I have looked around and completed a few searches but cannot find any direct answers to this.
I have CPU Spy installed and have been checking it off and on since I got the phone. I have noticed that my phone does not run at any speed other than the absolute max. The phone does go into Deep Sleep without issue, but the only CPU speed it uses is 1728. I have tried a few ROMS without any change.
Currently running Juggernaut 5.0 with Darky's Kernal.
I have tried different Governers. I have tried Antutu's CPU Master, SetCPU and No-Frills. I just cannot get this phone to run anything other than MAX speed. Since I am constantly having things run in the background like music, this is effecting my battery life.
Anyone have any input, ideas or suggestions? Other than running stock.

Turn down your minimum CPU settings in set CPU and check set on boot?

You've done just about everything possible. Only option left it to Odin back to stock, root it and check cpu Spy to see if it is acting normal. If it is back to normal flash back to your favorite distro!
Perhaps something got messed up along the way of flashing all those roms? Shouldn't, but you never know.

I was really hoping it would not come to this :'(
*update....
I re-flashed Darky's Kernal and removed all OC apps and now I am showing full utilization of the different seed steps.
Quite glad it did not result in me having to start over again.

[Q] SetCPU Randomly Rebooting One X?

Hi All,
After being a long time iPhone user i recently purchased htc one x, as a result my android skills are almost non-existent; so please bear with me.
I managed to flash clockworkmod recovery and rooted with SuperSU with no issues.
Purchased setCPU after reading the reviews and enabled. However the phone would reboot randomly a few times a day. Ususally when the screen was off.
After disabling setCPU there was no rebooting issue.
Has anyone got this app to work on the OneX, and if so which settings did you use?
Also has it been confirmed to work with all 4 cores?
FYI I had the following profiles setup.
Screen Off
Freq:640Mhz-51Mhz
Gov: conservative
Temp > 44.5
Freq:880Mhz-51Mhz
Gov: conservative
Battery < 30%
Freq:1000Mhz-51Mhz
Gov: powersave
Charging Any
Freq:1500Mhz-51Mhz
Gov: ondemand
Please note these profiles are based on no evidence, just on what I estimated to be about right...
Cheers

I did not start using SetCPU on my phone yet because it's not rooted, but first I would check if SetCPU doesn't require some kernel support? and if that's implemented in the custom ROM you're using? (if it's needed, I'm not sure).
Or maybe SetCPU needs an update to properly support our phones?
That Temp > 44.5 Profile, wouldn't that interfere with gaming? I have never used Temp profiles before (is it really needed?), only the other ones, like battery and screen-off and charging.

my one x has unlocked bootloader, recovery and root. I was running into some serious intermittent lagging issues, the phone in any app would just stall for 5+ seconds. after hours restoring after failure , it came down to the problem that using ANY cpu controll app, messed my phone up... BADLY! it seems at the moment (im assuming) apps like setcpu and cpu master are not quad core ready...

thanks for the responses guys.
I guess ill just wait until one of the devs can confirm this as working...

The reason is simple. We don't have rooted kernels yet. Until then stay away from messing with CPU speeds or under volting. Etc.

DO NOT mess with your CPU speeds yet. Undervoltage is causing reboots!

the software is not up to the hardware capability, i dont think the cpu control apps can handle quad core yet. and there is a lot of apps (esp. games) that lag a lot, and amazingly the cores are too lazy to work... im hoping for a better kernel that will address this issues.

If you want to at least see what's going on with the cores, I can confirm that Tablet CPU Usage Monitor works on HTC One X
It shows 2 icons in notification bar, each icon showing usage of 2 cores. Not sure how accurate it is, but so far had no problems with it and it seems to be reporting correctly. Developer is working on single icon with all 4cores in it, to save space.

I had the same problem, but if you delete your profiles you won't get reboots.
I'm just running default profile Max: 1500, Min: 760 Ondemand gov. and it has been a straight line for 6 hours when I was sleeping and no reboots.

I was having that problem too... In my opinion, I don't think that the phone can handle the Conservative governor setting. I set my governor to Interactive (On Demand works too)
Right now, I have my profile set to 1000mhz max and 475mhz min, with screen off profiles set to 475mhz max and min. I have not had any problems with the phone rebooting at all since setting those freqs. (And I don't want to quite go any lower yet). And I have it Set on Boot.

im now using rooted HTC One X(HOX) and installed RD-MIUI ROM quite sometimes. my kernel is still in stock. Im using setcpu and NO random reboot happen like what you have said. Yet, i am still confuse whether setcpu is good for my phone. based on my review, in the leading rom developer thread they not mention setcpu for their choice. they play alot with kernels to govern their hox cpu-s. could anyone do some comment.

CPU Frequencies Won't Stick

I downloaded Rom Toolbox Pro last night and attempted to use the CPU Controller part of the app and for the life of me I could not get the minimum frequency to stick. I kept dragging it down, like I had setcpu set up, and when I would exit the program then open it back up, the minimum frequency had jumped back up. If I went to re-install SETCPU I was able to change the minimum frequency and it would stick just fine. Anyone else had any trouble getting the frequencies to stick?
I also tried this on CPU Master and the minimum frequency wouldn't stick there either. Anyone have any ideas?
I am on FreeGS3v0.0.9

Must have custom kernal that supports overclocking or a custom rom/kernal combo.

Well I'm actually underclocking, but the ROM I am on has a kernel that supports underclocking, so it should work as I stated above

I don't believe the kernal in Free supports under or overclocking, have you tried kettle korn kernal?

I'm having the same problem with the max frequency not sticking I'll set it to 2265 exit performance settings and a minute later go back in and it will have underclocked itself to various settings I've tried many different CPU control apps and none of them are able to get a lock

CPU pegged at high speed after USB mount

On my N7100 Note 2 (international, LJ3, rooted), every time I mount am USB stick through the otg cable, after I securely unmount it, I get CPU pegged at 1100 MHz, and no deep sleep.
To restore normal functionality, I have to reboot.
Is it only me? I have monitored cpu frequencies with the "cpu spy" application.

I'm analyzing the issue.
After umounting, OS monitor indicates that android.process.media is getting high cpu load. I've killed the process, and cpu gets relieved, and doesn't show pegged at 1100 MHz any more.
But, afterwards, the device still doesnt' go into deep sleep.
Better battery monitor indicates that "UsbStorageUnmountter" is issuing partial wakelocks, at almost full time.
How can I kill it?

I've searched in these forums for "usbstorageunmountter". It seems it's a common issue for Samsung devices.
There's the suggestion to unmount the usb stick through the settings-storage menu (in http://forum.xda-developers.com/showpost.php?p=28668028&postcount=3 ) but unfortunately that doesn't work.
Also unplugging abruptly the stick, as suggested elsewhere, doesn't work, and additionally can be dangeruous for the the file system.

There is a solution, eventually

Remember to stop the Media Server after unmounting your usb stick, otherwise cpu could stay pegged at max frequency.

Can anyone help about how to stop this Media Server? I tried with stock task manager and Advanced Task Killer and it doesn't even show it.
I have a Note (N7000) which doesn't enter in deep sleep after unplugging a USB stick. BetterBattery Stats shows "UsbStorageUnmountter" as patiial wakelock all the time. I just can't kill this unless reboot. I find frustrating to reboot phone after using a stick!
My phone is not rooted I don't intend to root it.
Thanks!
