Gpu overclock - Galaxy Note II Q&A, Help & Troubleshooting

Hello
I'm currently using a note2core asylum kernel which supports both cpu and gpu overclocking. My question is, how do I go about overclocking the gpu? Any help will be appreciated.

Don't need that overclock note 2 is an excellent phone more than a phone...my oppinion

I know. Its all for.research purposes anyway

I'm not sure if note2core supports stweak but that's the app you need to over clock. There are other but I prefer this one. It will give you a maximum slide to 1800mhz and also tons of other features such as adjusting charging amp, under volting including for the gpu as well. There's not much to know about over clocking as its pretty straight forward but you can change the xpu governor and the number of cores you want activated and how you want them to activate based on your usage. Under volting will help with both temperature and battery life although I find the changes almost insignificant, but you should try it out. If you want to undervolt start with around - 25mv.

You are talking about cpu not gpu

Okay it's not that different. Just over clock it and undervolt at the same time to - 25mv and then download an app called stabilitytest from play store. Run it for 10minutes and see if you get any error. If not then further lower the voltage to - 50mv. But usually - 25 is good. I noticed that anything higher clocks peed than 5xxmhz starts causing error and graphic glitches.

CPU apps

I'm having trouble finding a CPU app that works perfectly with this phone. I've tried setcpu, CPU master, system tuner, and nstools. What's everyone using to oc this thing?

Depends on which rom your running but in general...you should use none. Most roms already uv and oc and if u use an app it'll butt heads.

My issue is that it seems like my phone is skipping steps all over the place. I'm using cpuspy and the usage jumps between Max/min clocks. I'm kinda not digging that. Its the same with every rom i flash.

That's not an issue with your cpu app. It has to do with your governor (the thing that controls how your CPU scales). Most ROMs come with ondemand by default which pretty much does exactly that, which is jump from min to max as needed. If you want something that scales more, you should look at conservative (for better battery life) or lagfree/interactive (for better performance). Lagfree/interactive are only available on select kernels though (whereas conservative is almost universally available). Streamline definitely has them and I think synergy does too.
Also CPU apps don't butt heads with the ROM/kernel default settings, it just overrides the default settings.
Yea I figured that but this is the first phone I've had where on demand performs that way. I've had a nexus s, epic 4g, evo, and a g2 and they all scaled across the steps ondemand. Ondemand on this phone works like the min/max governor. But your right conservative scales across the steps well. Just a bit choppier. About to install nstools and mess with the threshholds and whatnot.

[Q] Voltage settings

Just curious to see what voltage settings people were using in conjunction with joker's kernel. Screen shots? Post? Whatever. I'm interested!

I'm -50 undervolt a running good. No random reboots or anything. Even played Dead Trigger for an hour and all good. I am also running at 1.62 overclock. All is good.

Running 25 under and still good. I'll probably overclock it to get better performance.

I assume you are -50 on just the highest clock setting?

No -50 on all clock speeds. I use faux123 from the market. I was running -25 then just bumped it down some more. Might try -75 soon.

A CPU question

I want to over clock my phone and under clock it when I'm not using it to save battery life is there anyway to do this I've tried a few apps and they didn't do much
What is the lowest clock rate for the phone bc on the apps it puts it at 384
Thanks for the help

The lowest safe rate would be 384 but you would be a lot better off
to get the "JuiceDefender" app from the play store.
It has a lot of features including auto cpu frequency and you can set it up
so it automatically handles all options needed for the very best battery
savings modes without sacrificing performance...
My personal opinion which is not worth much is NOT to mess with
manually over clocking, under clocking or volting but instead use a
true and tried app like JuiceDefender to do all the work for you.
Check it out at the play store.
Thanks I'll try it out

Hey i got a question about CPU. Im running wicked rom with Deviant Kernel. My max and min freq keep changing. My kernel allows me to overclock to 1944 but i set it to 1620 and min at384. im using smartsassv2 and cfq but it keeps making my maximum 1350. no matter what i change the gov. to or the max. I reinstalled rom and and the kernel seperate. to see if it would make a differecne and same results. Please Please Please help me fix this
I'm not an expert but I think I can some what help you. Are you toggling the set on boot?
Sent from my SGH-T999 using xda app-developers app
You need to install a custom kernel and possibly a custom ROM.
Then you can overclock/underclock to what your kernel supports.
I've seen kernels that allow min at 94 and max at 1944.

CPU core spikes

Hey my CPU cores keep going to 1.9ghz making my phone hot. I'm on deviant kernel 7 hypedrive rsl12. I have it on Pegasus and zen I/o scheduler and max set to 1.5 and min to 192mhz please help its killing my battery.

Flash another kernel, change your governors, under volt, underclock.
Have you tried any of those?
Also make sure no other apps are messing with your processor speed, or certain setting applied at boot.

Enable CPU power saving in settings. This would limit max speed to 1.26.

Neighborhoodhacker's Kernel: 3.4 CM based Kernel w/ Overclock and more

This is a kernel I have made based off of the Gproject kernel for CM.
Features:
10/25
Added wheatley and smartmax governors. As many TCP congestion options as one could ask for. A couple other small things.
10/24-4
Fix CM compatibility break. Bye bye LSD effect
10/24-3
The kernel package is now using an implementation of koush's anykernel.
I suggest for those who are having any issue to flash back to their ROM image (don't delete data). Then reflash using this. It uses the ramdisk already present on the device so it might break less things
10/24-2
Reset the GPU min freq to stock so that we don't lose battery
10/24
GPU OC extended for to 585Mhz. Woot woot.
10/23
1.89Ghz if you dare MWAHAHAHA
10/22
162Mhz was a little bit hopeful so I got rid of the frequency because without that we seem to lose the HW resets. Overclock still seems to work fine Antutu 20200.
10/21
Overhauled the CPU frequency range. We now have stable OC to 1.81 and UC to 162Mhz. Depending on the application you can toy with intellithermal settings to get the best performance from that situation.
Edit: not so stable at 1.81 I lied go for 1.72 for now (always forced to eat my words)
10/17
Quite a few changes. We have an updated wifi driver as well as an updated graphics driver. I added gamma control. Simple GPU governor is now set to default for battery savings and by that one can imply obviously it is working now. FIOPS scheduler added. A few minor things.
9/30-2
removed knock knock by farbuggy
9/30
Okay so I am really really really hoping this one rids SOD's good. Also I added a knock on interface. Until it gets implemented into the systemui of a rom though it will only work while screen is off. (It's a work in progress and the knock on ability is disablable though the file /sys/kernel/knock_knock/knock_knock_enabled[1 = on, 0 = off]) This I believe is the first custom kernel to have any kind of knock on type interface. So far it's just been made up for by showp-1985's s2w.
9/29
Tweaked undervolt so hopefully we can say goodbye to SOD's. I have had success with lower settings but this should cover a broader base. If anyone get's an SOD with these settings, let me know and I will update the kernel ASAP.
9/28
Added undervolt by default and faux123 mako's implementation of sweep2wake. It doesn't show in tricksters mod but you can turn it on and off in sysfs through the file /sys/kernel/s2w_parameters/s2w_switch. (1 = on, 0 = off)
9/27
Ummm let's see... Today we got: GPU Overclock to 487Mhz, intelli-thermal from faux123, and a couple little things here and there .
Edit: I added a little more there is now an adjustable voltage table and the phone defaults with intelliplug and intellithermal
9/26
Intellidemand doesn't control hotplugging anymore. That functionality is moved to intelliplug. I think we have hotplugging and performance now let me know all! (mpdecision still enabled by default, go to trickster and see the new additions )
9/25
Faux sound control.
Intellidemand. (mpdecision should be turned off to utilize this feature properly)
Extended CPU frequency range (192Mhz - 1728Mhz)

Maybe it has something to do with MPDecision or temp throttling? I know in the past I've seen other kernels have some issue at first with fully disabling it, causing it to continue to interfere with some settings.
Awesome work..... With faux
Thank you for cooking it

I'm not an expert on governors but with intellidemand (on our other roms) my optimal freq and sync freq were usually like 702mhz. Stock this kernel puts it at 192mhz. Correct me if I'm wrong, I'm not sure what these fields even mean. I'd like to know if anyone has any info.
I'm running the kernel anyway and so far so good. Thank you NeighborhoodHacker for this great kernel.
edit: I just tested Asphalt 8 and so far this kernel holds frame rates really well!! I don't if I was doing something wrong before, but for the longest time this game was unplayable for me.

Ummmm try wiping cache/dalvik/ I highly doubt you are anything but slightly softbricked.
Having great success with with newest kernel. I even got an antutu of over 19000 with a hotplugging driver enabled! I'm pretty happy so I hope your guys experieces will mirror mine.
Well originally I ran antutu, then the phone went off, and notification light and capacitive lights flashed. I couldn't access recovery do I attempted a lgnsp. Now it won't even charge or turn on

All you had to do was wipe caches after your cash. Since you ran out your battery you made things so hard on yourself

Also if you want good performance and hotplugging go to tricksters mod enable intelliplug and temperature throttle
