Hi,
I have a rooted sm-p600. I have been finding ways to speed up my tablet and reduce (if not totally eliminate) the lag.
First, I installed wanam xposed module and enabled/disabled the "touchwiz DVFS" option and "Enable boost mode" option. I don't know if it makes any difference and I'm not totally sure either what that option is for. So if anyone could tell me if I should enable/disable it, that'll be great,
Second, I tried to use an overclocking app, "no-frills cpu" and "cpu tuner". I know that I actually have to have a custom kernel which enables overclocking but I really didn't need to overclock my tablet, I just basically want to keep my min and max frequencies to 1.9 so that means, it won't try to underclock my cputo save battery (which the kernel is doing by default). It works great and it DID eliminate the lag and the tablet was so snappy. But there's one glitch. If I lock the tablet, it fails to wake up. And I had to do a forced reboot. But there's one thing I've noticed and this may be of help to someone who is trying to figure out how to eliminate the known lag issue in the note 10.1 (2014). It only hangs if the tablet is not charging. Meaning, if I set the max and min frequencies to 1.9ghz, it hangs (once locked) if the tablet is not plugged into the charger. If I plug it into the charger, even if I lock it and unlock it several times, it doesn't hang.
So, anybody got any clue as to how to resolve this issue? Or has anyone come up with a better kernel for this tablet?
Try setting the min to 1.3 ghz see what that does or try using flux to set min Max and memory read times to 3072 or whatever the value is I forget. Play around with the settings and I'm sure you will find a better more stable experience. I don't know how having two quad cores affects the performance maybe that's why you getting the black screen and no wake on battery. It might have to tick over the lower quad first before it kicks in the main one. Might be taxing the battery to much clocking straight to 1.9. Hope this helps let me know how you get on

Which overclocking app are you referring to? I would assume you're talking about "cpu tuner" as the other app I've mentioned in my initial pose which is "no-frills cpu control" doesn't have any other settings besides the min and max frequency.
GOOD NEWS though! I got cpu tuner to work! I did lower the min frequency to 1.8ghz and kept max at 1.9ghz. Actually, there are only 3 selectable values for both fields, it's 250mhz, 1.8ghz and 1.9ghz. I gave 1.8ghz a try, locked the tablet, it froze, then I restarted it. The settings were reapplied when I logged back in, then after that it never froze again even after I've locked it a few times. The performance is excellent! I tried running multiple apps on pen window. I've never seen it perform this well since I bought this tablet! Let's see if it works well in a few days.

Yeah best to try flux123 kernal app on the playstore you can set a lot more in there. Works like a treat on my s4. Set it to 1.3 and 1.9. I'll post some more settings to try later. All I've got is nova launcher and disabled as much blout that I don't use. Not yet rooted on my tablet but just doing them two simple things makes a ton of difference. As you rooted you could use root uninstaller to remove touchwiz and other stupid startup processes. I did it last week on my tab 8.0 got rid of 12 pointless processes now that flys wouldn't even think it was the tablet. Can't wait for a oc kernel and decent rom for the note 10.1 will come into its own then. To bad Samsung killed it with all there unneeded rubbish .

At this point, I don't really mind the slight degrading of the battery life, I just want the tablet to be snappier.
By the way, I installed faux123, but it seems that I cannot change the settings. Like when I try to drag the min frequency slider to 1.3ghz, it slides back to 250mhz. Also, all of the other settings I set revert back to the original settings after I reboot. I have enabled the "set on boot" options on all screens, but they all just revert back to original settings on reboot. Am I missing something?

Just came back to check for anymore help I could give and the best thing I can advice is clean rom. Fly's with nova launcher but still haven't got any kernals to take advantage of flux yet which sucks abit but trust me you won't be disappointed by clean rom if you haven't already got it on your tab don't waste another second

Hi all I'm fairly new to these forums, although I have been watching from afar for quite some while now!
I have been trying out custom roms and various kernels and was wondering how do I go about overclocking my device? Only reason I am asking is because I was checking out benckmark results for other devices and noticed some can be particularly high.
Any insight would be most appreciated!
I wouldnt try any overclocking on the HOX because of the heat issues. A more safe and stable way of doing it is changing the govenor of the kernel or forcing cores online. I think you can use core control (in the apps and themes section) to change core behaviour and system tuner to change govenor.

I have now installed core control. Got to admit it is nice having the option to save a bit more power. How much as an estimate do each of cores use anyway just out of interest?

you can download an app called tegrastats to find out more but all you should know is this. once you activate the corecontrol and depending what app you use you should be fine. if i was you i would also use no-frills cpu app. that way you can underclock and would save you more juice

Fantastic! Many thanks for the advice. I have now installed no-frills cpu, and started to tinker around with the settings. Could I ask as I am still fairly new to some of this, when I first went on to the settings both maximum and minimum were set to 1.5 GHz (Not sure if it was just saying this on the app or not or if these are the actual settings) but I would guess this would use a lot more power am I right?

yes you are right. put the min frequency to say 200 or 300 mhz and then press apply on boot and then reboot and you should be fine
Hey I just bought a 32 GB Gnex and got it yesterday but it seems to be unstable at anything above the stock max frequency of 1230 MHz. I've tried Paranoid Android and last night's CM10 nightly and they would both freeze and immediately reboot upon setting it to 1305 MHz. I then flashed the Zen kernel on top of CM10 and I like that it can go up to 1.8 GHz but whenever I set anything beyond 1.23 GHz it starts to lag for about 1-3 seconds. When I knock it back down to 1.23 GHz everything is fine again.
This is the first OMAP device I have since I had the OG Droid back in 09, I loved how they were extremely overclockable and I'm going to be pretty sad if mine has to stay at stock speeds. I've tried using JRummy's ROM Toolbox Pro and the built in Performance settings to try and set the frequencies but it doesn't seem to make a difference on which one I use. I've been using the OnDemand and Interactive(x) Governors.
Is this a known problem or am I alone on this?
some CPUs have a higher tolerance than others for overclocking. looks like you got one of the super low tolerance ones.
I hope that's not the case :-/

you need to disable smart reflex mpu if you want to overclock. smart reflex doesnt know overclocking, so it sets your voltages to low for an overclocked cpu. thus, instant instability.
to disable smart reflex manually, use a terminal emulator. type su(press enter) then type these 3 lines and press enter after each..
*
echo "0" > /sys/kernel/debug/smartreflex/sr_mpu/autocomp
0 to disable, 1 to enable.
btw, some cpu control apps give you options to disable/enable smart reflex.
What three lines? I only see one...
I echo'd a value of "0" to the file but it was still unstable at 1.8 GHz, haven't tried lower frequencies yet, I don't have to reboot after setting the value, correct?
edit: still unstable at 1.42 GHz, also what apps would those be that allow this? Antutu CPU Master Pro only has an option to disable PerfLock.
the way to overclock is to keep moving in small increments upward and burn testing them to check for stability. Don't go straight for a 50% overclock. move up and find your threashold, and when you do start tweaking to see if you can slowly creep beyond that

The 3 lines would be:
Code:
echo "0" > /sys/kernel/debug/smartreflex/sr_mpu/autocomp
echo "0" > /sys/kernel/debug/smartreflex/sr_core/autocomp
echo "0" > /sys/kernel/debug/smartreflex/sr_iva/autocomp
Frankly, though, don't expect 1.8GHz to be stable.
Your particular device's components might not hold it together with that oc.

Yea I know (I used to OC the CPU on my PC), I just wanted to go for something big to see if it could handle it.
Edit: seems to be stable at 1.4 GHz, I'm going to keep increasing it to see what the limit is. I'm assuming i'd have to turn off smartreflex on each boot so I should probably put it in a script in /etc/init.d correct?

the trinity kernel toolbox lets you disable/enable smart reflex. plus, extremely few gnex will oc to 1.8ghz. and on top of that, to oc even to 1.4 or 1.5ghz, youll need to adjust your voltages to get yourself stable. every device likes different voltages.
I had it stable at 1.4, 1.5, 1.6, 1.7 and told my GF that I could OC it now (because I told her before that I didn't think I could) ...and then it froze rock solid lol

i can oc my gnex(using trinity kernel) to 1.803ghz.. but to use stable for every day, 1.689ghz is a good speed for my device. a majority of devices wont even oc that high and stable. stable being the key word.

I'd find it surprising that you got 4 different overclock levels stable in 30 minutes. There's a difference between "it boots", "it boots and runs some apps", and "stable".

I'm running the 11/4 build of Paranoid Android with v3.0.51-ZenSeries v4 Tuna and I having problems setting CPU frequencies via Trinity Kernel Toolbox. The frequency will stick until I switch to another app, then when I come back to the app it will be at the stock max frequency. I am also unable to use the built in frequency tuner when using TKT.
I've tried stress testing it with stability test and even when the frequencies will stick in TKT (ex. 1.4 GHz) Stability Test will report that its at 1.1 GHz. WTF is going on here? I have all three of the smart reflex values disabled.

dont use PA cpu settings. do you have any other cpu control apps installed? make sure theres nothing enabled in PA cpu settings, nothing. then reboot. wait 2-3 after bootup then open tkt and try using it. is the problem still there?
It seems to be sticking now for the moment, but I haven't had anything in PA CPU settings before I rebooted anyway. I do not have any other CPU OC apps installed either. Stability test is reporting the correct frequency also. Thanks.

sweet.
if you were checking before 3 minutes after bootup, then that was the issue. whatever it was, lets hope it doesnt come back.
I was setting the values after the phone had been up for hours, idk what the problem was :-\q
so the Galaxy Nexus has a dual core 1.2ghz TI Omap right? thats 2 cores running at 1.2ghz each? or are the clockspeeds split between the cores?
using Kernel Tuner to manage my CPU speed i noticed that when i exit the CPU tab CPU1 goes offline until i hit CPU1 on/off. nice feature to be able to turn it on or off on the fly, but why isnt it on by default?
then after a while, even set to Performance mode and no matter what i set, my clockspeeds drop by half and fluctuate as if i have the governor set to Ondemand and again with only CPU0 activated slowing my phone down immensely!
im currently running Axi0m with Fancy Kernel but have noticed this on the included kernel and in EOS and SlimBean too.
its really annoying to watch Need for Speed Most Wanted fps drop gradually while racing, or even Into The Dead
is this my phone acting up or is this actually a Deep Sleep feature?

This may be an app compatibility issue. From the market Application officially supports only HTC EVO 3D GSM/CDMA, however it might also work on other devices. Try a different app, Trickster Mod perhaps.

This could be the app too. Performance governor should never fluctuate in speed. It should lock in at the top speed you have set, and never change from there. It could also be that you have something with profiles that changes your speeds/governors when certain requirements are met (under 50% battery underclock and use on demand governor).

There are settings and governors that do disable a core when sleeping, or when not needed in hopes of saving battery. Most don't come with this enabled by default, as there are some folks that run into stability issues with those options.

your right, Kernel Turner is "officially" only supported by HTC EVO 3d. ive used it on a bunch of other phones and never ran into any problems, like my Samsung Intercept and Evo Shift even an Exhibit 4g. will give Trickster Mod a go
by chance do you know if Axi0m rom has only 1 core enabled by default? i had noticed these sames fluctuations in it's built in CPU controller BEFORE i installed Kernel Tuner. actually this was the REASON i installed Kernel Tuner
also i dont have any profiles or apps set up to govern my CPU frequencies. literally have have 4 games, TerrariaHB and Kernel Tuner lol.
ok ive played around with it a little bit and still having the frequencies drop to 537 even with Trickster Mod, both cores are saying offline and i set frequency lock.
i had my phone set to 806mhz Performance, played with it for a few, come back and...well?
here it is AGAIN after just sitting there and clicking apply doesnt change it! i have to change the frequency then click apply and it does, but it only seems to for a few minutes
-_- im an idiot...
"Max Screen Off"
You will press v under status bar for apply with setting otherwise you will never stay at the same set than before
For apply at boot use settings > apply at boot
Don't use performance, it's useless and deprecated, use interactive instead

On my Galaxy Tab 3 (8 Inch) Whenever I set a profile (Screen off, go into conservative kernel for example), my Tab literally freezes. When I turn the screen back on and swipe the animation moves slightly then freezes and my Tab gets completely stuck(Have to force restart). Are screen off profiles or profiles in general not compatible with the GTab 3? :crying:

Update, after setting profiles in ROM Toolbox it seems to work fine, avoid SetCPU if you can. Seems to be incompatible.

I currently use ROM TOOLBOX and it does the job too bad had to buy new cpu overclocking tool when switched devices . . .
Do you too, have high cpu usage with only few apps on ? Think samsung apps takes a lot cpu ?
Today some strange things happens with the screen - tab turns off themscreen itself ,
-happend when layed down tje tablet on the desk (twice)
-happend when unused for a minute (screen is set to turn off after 10min)
Do or did you have similar behaviours?
I touched some no frills cpu control settings and now my benchmark results are about 19000-22000 and it used to be like 24000 i tried changing the rom and all that stuff if someone can give me the stock governator and all frequencys and that stuff it would be helpful.. Thanks i need help i dont know what to do
Now i cant do any better than 23000

Firstly, I assume by the size score that you are using Antutututu. If so then you always get variance in the scores, and yes it can be 4k difference.
Next, I'm gonna bet that you are seeing thermal throttling, where the device is turning off 2 of the cores due to heat.
I've only noticed this behaviour recently myself. It's a real pain in the arse. I've downloaded trinity kernel app to get around the problem. In his app you can turn off thermal throttling and force the two other Cores to stay on.
This isn't a permanent fix though as the settings don't want to stick for some reason that is beyond me.
Next, is there no reset to default in no frills cpu app ?
Or you can uninstall no frills and make sure you delete any folders off your sd card, then either reflash your rom or you could even flash AICP kernel.
This should get you back to default.
Finally if you still think it's your settings, you could tell us all the settings you have changed and between the guys on the forum we could tell you what to change back to.
All the best rich
**just had a quick look at no frills on play Store. Looks like there's not loads to alter.
I like interactive governer and row scheduler (as we can't get row I use deadline.)
Min frequency wants to be at 384 and max at 1728.
That's the basics.
