Sm-t550 galaxy tab a custom kernel for overclocking cpu/gpu ? - Android Q&A, Help & Troubleshooting

Picked up a Samsung Galaxy Tab A model sm-t550
Rooted , dexodexed stock touchwiz rom 5.0.2 with xposed framework v83 for samsung touchwiz 5.0.x. Everything works great. Would like to overclock the cpu/gpu for gaming though.
Android version 5.0.2
Kernel 3.10.49-5975984
Build number SM-T550_XXU1AOJ1_ASHYX
However, since this is a new tab, there doesnt seem to be any custom roms
or kernels yet for this one. ( I would really like CM rom! )
I would like to overclock the cpu if possible, and understand that a
custom kernel is necessary.
(1) is there a way to quickly hex-edit some values in the kernel to achieve overclocking?
(2) or if someone could make a custom kernel for stock touchwiz 5.0.2
I would be willing to test it.
Thanks!

My opinion ( im doing so ) is that the best, fastest and stablest roms are stock roms with a custom kernel
i own a I9001 galaxy s plus with the latest valuepack stock firmware by samsung and the sky high kernel v.1.4
it ssmooth and fast and stable
im running it since a week and no problems since now
i also tried many custom roms but in many cases u always find a bug
the sky high kernel for my device allows me to oc it to 1.8GHZ
The I/O Shedulers are great im using 1.4 GHZ (standart) and the interactivex sheduler
Hey guys. Just one question, is it possible to update Samsung GS Wifi 5.0 YP-G70 to Android 4.0?

[solved] Need for speed - most wanted freezing

Hi. I bought NFS: MW few days ago and it was running fine on sammy's stock 4.1.2. I decided to flash custom rom to get better performance, but the game freezes my phone shortly after starting the race. Audio is stuck as well and I can only turn it off by holding power or removing the battery. Those are the roms I tried so far, it freezes on all of them the same way.
Cyanogen 10.1 - nightly (latest) (CM's kernel)
Cyanogen 10.1 - nightly (latest) + Dorimanx 9.41
CM-10.1.3-i9100 (stable) - default kernel
CM-10.1.3-i9100 (stable) - Dorimanx 9.41
Sentinel Rom 4.80 (default kernel)
Sentinel Rom 4.80 + Dorimanx 9.34
Sentinel Rom 4.80 + Dorimanx 9.41
I tried turning on Force GPU Rendering and I tried "Disable HW overlays" in dev. options. Any other ideas?
This is called "The Mali Bug" . All CyanogenMod ,and ROMs based on that have it.That means on heavy GPU load,like NFS,it will simply freeze,no matter what kernel you are using.All CM 10,1 and 10.2 are bugged.Your options are:
- go back to stock 4.1.2 ROM,or stock based
- use an older CyanogenMod (CM 10 and older doesn't have this problem.)
- Carbon ROM is the only non stock based ROM without Mali bug.You can try it.
Some ROMs have a base code to programming, TouchWiz per example give support to Samsung apps, and this apps can't run on other ROMs. In case of heavy games like NFS, which have a specific programation to use all HD potencial of the hardware, they may use this base to make game run faster and clean. Maybe this explain why NFS can't run in custom ROMs.
I read some ROM threads which said in the post NFS isn't compatible when someone ask about game compatiblity...
Sorry about any mistakes if i wrote something wrong. English isn't my natural language
Thank you for letting me know about "The Mali Bug". I will try Carbon ROM since I am already flashing/wiping and if I don't like it I'll get back on stock.

You can use Boeffla kernel. You can overclock your CPU with the Boeffla config app. Download: http://www.boeffla-kernel.de/index.php/downloads-samsung-phones
I had Boeffla kernel installed,but it can go max to 2.84 ghz.I recently installed fusion rom and got a stable 3.0 ghz overclock,but i would like to make that overclock on a stock samsung rom.

http://gnutoolchains.com/download/
but I don't know to make an custom kernel and I am using win10. But I want to make a bit overckocked like these threads to G850F variant of Alpha (A15(big)Core Clock 2.0Ghz~0.5Ghz about max %11.1... overclocked, A7(Little)Core Clock 1.5Ghz~0.2Ghz about %15.384) (http://forum.xda-developers.com/galaxy-alpha/development/kitakernel-v3-2-1-sm-g850s-k-l-t3272876)
(http://forum.xda-developers.com/galaxy-alpha/orig-development/kernel-custom-kernel-t2981120)And This kernel has overclock supported but this kernel isn't compatible with LOLLIPOP.

Can Someone Help me?

Overclocking GT-i9100M on Custom ROM

Hello,
I'm having trouble in my attempt to overclock an i9100M (using an i9100 ROM) on more modern ROM variants. I'm on the unofficial Lineage OS 19.0/Android 12 ROM (though I should probably go with something older) and I've tried 2 apps to no avail (SetCPU and Tegrak Overclock) due to their age. Has anyone had success in any overclocking on recent custom ROMs for this device?
