[Help] GPU Overclocking - Sony Xperia Z Ultra

Hi,
I've tried different kernel with different roms, DoomKernel, GreaDevs Kernel.
But I cannot overclock the GPU, it says 450Mhz max with any kernel, is there something I've done wrong?
I'm on Z Ultra 6833, please help.
Thank you

Up, please I need to know how to get the GPU overclocking working. Thanks.

Freind u won't get ne reply here, people here are oldies they don't try anything new..they r a great bore..I also wanted to know that BT people here never answer..I think the main reason is the codes are actually dirty coded..so they don't work as they should..if u want some extra performance try using custom roms.

Well, I really hoped someone had an answer to fix this. Well I'll keep on trying eventually I'll find a way, if someone can do it, it should be doable on every Z Ultra.

This one lists oc up to 600mhz as a feature. Finding a compatible ROM will be your next step.

Thank you, I've tried that kernel, no GPU overclocking possible, neither via any app, or echoing the frequency to the max_oc settings file.
Other than that the kernel it is a total mess, phone couldn't shut off, kept restarting on it's own, the kernel got rid of my recovery.
I tried to flash a new recovery but, rashr couldn't do it, fastboot couldn't do it (even it said flash was ok), and z ultra multi recovery script could not do it.
Ended up restoring an FTF.
Seriously is any developer willing to uncover the mistery of GPU overclock on this device?
Somebody that can use it and wants to tell me it's rom and kernel combination, and how to get this thing working?
I would appreciate, on all the phones I've ever had, if a kernel had GPU overclock, it worked regardlessly of the rom, and echoing with init.d has always worked in the past, with the Z ultra nothing seems to work!!
Sorry for my broken english.

What is your real purpose of being able to overclock parameters...? Before it was possible with kernels built by chefs but now we have Lollipop 5.1.x, we have stable releases of those (not called stable but they are "stable" in terms of runtime, we have ART which have been improved a lot since its debut. And the Snapdragon 800 powering your device does not put you down even today when its two years old.
If you have perfomance issues with your device..and feel the need to "overclock" either the cpu or the gpu you probably doing something wrong.
The only thing you will achieve by overclocking is your phone starting to cook..with ART the phone heats up very quickly.

More than 2 months i was not able to OC the GPU, doesn't matter the combination of rom and kernel.
If there is anyone that have a clue on how to do it, please help me out.

If you wnat to overclock your GPU, you must have kernel support, or default is 450MHz
