Its buggy and causing issues so its removed temporarily.

1700Mhz A15 and 1500Mhz A7 running together with 640Mhz PowerVR SGX.
[Galaxy S 4 i9500 Original Android Development] dazkyl:
Any idea why i left all the voltages at default and just oced the cpu to 1.7 and my phone is freezing ?
[Galaxy S 4 i9500 Original Android Development] hotheabilly:
maybe your chip doesn't support OC, try to add 1/2 steps voltage to the freq. overvolting the clock maybe dangerous, but its increasing the stability
[Galaxy S 4 i9500 Original Android Development] dazkyl:
When i try to oc the voltage step for example of the 1.7mhz step , it instantly freezes.

If i leave the cpu max frequency at 1.7 , and the set on boot option is not ticked , and i restart my phone , does the cpu stay overclocked at 1.7 ?

Edit : i just un-ticked set on boot in the cpu section and when rebooting everything is fine and the cpu max frequency is being set where i left it before rebooting . So is the cpu staying overclocked at 1.7 even though set on boot is un-ticked ?

Hi friends....

I'm on Perseus 6.2 w/ Omega ROM 10 / Crossbreeder...

I'm using Ondemand-Sec as my Governer.... I selected it in SetCpu

Just wanted to tweak this Governer in SetCpu... Actually I wanna change certain values for performance such as:

- Up Threshold

- Sample Rate

- Sampling Down Factor

- Down Differential

- Frequency Step

Up Threshold from 90 to 80

Sample Rate from 100000 to 80000

Sampling Down Factor from 1 to 2

Somehow I don't see Down Differential & Frequency Step .... Moreover when I change the Up Threshold value to 80, it reverts back to default (90)...

Can anyone plz advise/ suggest???

Thanks

What does the ''Set on boot'' option in stweaks do? i have it un-ticked , i mean i just overclocked my cpu from 1.6 way up to 1.9 , and rebooted my phone and when i opened stweaks again , it was still showing 1.9 while my set on boot option is not ticked.
[Galaxy S 4 i9500 Original Android Development] dragon135:
It means it will not applied your choice if you reboot. Of course it still save your choice.

[Galaxy S 4 i9500 Original Android Development] dazkyl:
So if i reboot and need to overclock the cpu again. to 1.9, do i need to apply it again?
[Galaxy S 4 i9500 Original Android Development] droidphile:
Stweaks shows the values as read from it's current .profile file, not from real time sysfs values. All "tuner" user space apps and even init.d scripts can override stweaks. Keep these two points in mind, or one will be very confused.
[Galaxy S 4 i9500 Original Android Development] dazkyl:
So in reality isn't the 1.9ghz being applied although im applying it? I do not have any other applications except for stweaks. Where can i find the profile please?
[Galaxy S 4 i9500 Original Android Development] droidphile:
I was talking about how Stweaks reads and displays the values, and how other apps/scripts can override it. Applying a value take effects immediately in almost all the cases. Set 'apply on boot' for the setting to be persistent across reboots. Profiles are in /data/.perseus.
[Galaxy S 4 i9500 Original Android Development] dazkyl:
Dunno why phone freezes upon reboot when set on boot is checked, although cpu at 1.9 is stable.

[Galaxy S 4 i9500 Original Android Development] Trek55:
how bout using root explorer?
[Galaxy S 4 i9500 Original Android Development] dazkyl:
Tried it as well.

Edit. i found it with root explorer ! With what can i open the profiles and edit them?
[Galaxy S 4 i9500 Original Android Development] dragon135:
I got hot restarts fiesta, it always restarts after 2 minutes after power on. Plugout battery is still same.

I enter stweaks asap then reset setting and the problem stop.

I only changed cpu min freq to 100Mhz and set on boot.

This restart happened 2 days ago also.

Note: weird thing is when apply changes after reset stweaks it always reports changing storage scheduler to noop although noop is already the default.

[Galaxy S 4 i9500 Original Android Development] dazkyl:
Guys , my current 1900mhz step voltage in STweaks is at 1225000uV. I just edited this voltage step from the profile text editor and bumped it a little higher to 1237500. When i saved it , STweaks was still showing the default voltage although i changed it from the profile text editor.Which voltage has the highest priority and is active? The voltage in stweaks or in the profile editor ?

I did this because when i move voltages directly from stweaks , phone freezes.
[Galaxy S 4 i9500 Original Android Development] sak500:
Same issue happened with version 6 when i tried to increase teh A7 to 750, the phone froze and then restarted itself and every time it reached the icon loading stage it would freeze and reboot. Tried flashing version 5 then 4 same thing. Flashed adam's kernel and it would boot up normally. Reset the stweaks and then flashed alpha 6 and then again freezing and rebooting cycle. Flashed crash rom again and then tried and it would still freeze and reboot. So finally i again reset stweaks using adam's kernel then cleared dalvik / cache then flashed 4 then 5 then 6 and finally it worked . Now @ 1.7ghz A15 and 1.3 A7 with default u/v which comes to about -75 across.

Does your phone freeze when messing a voltage?

---------- Post added at 11:48 AM ---------- Previous post was at 11:42 AM ----------

omg ! when ticking set on boot option , even though my phone is stable with the settings , phone freezes upon boot.
[Galaxy S 4 i9500 Original Android Development] sak500:
Yes earlier i was changing voltage of 200mhz slab and it froze. I've kept minimum 200 max 1700. But now by default whenever i install perseus kernel voltage is automatically lower than standard.
[Galaxy S 4 i9500 Original Android Development] dazkyl:
Thats whats happening to me. When messing with voltages it freezes. When overclocking the cpu s and leaving the voltages at the defauly underclocked value, then it works this way.

[Galaxy S 4 i9500 Original Android Development] diego9016:
Maybe I'm wrong but I think this is not relevant to Perseos kernel.
[Galaxy S 4 i9500 Original Android Development] Fienman:
Not completely, but it is partially related.

The link is about a new and improved version of the processor found in i9500 on which Perseus kernel is based.

The new processor should be like a Rev 2.0. It might not be crippled like the one found in i9500.

Thus, it might be the first proper "Octa" processor.

Many people were unhappy in this thread about the i9500 proc not working as it was supposed to.

When we will have a proper working one, we can isolate the difference.

Also like in the S3 and Note 2 case. The other processor is higher clocked and can further demonstrate the capabilities/limits of this Chipset.
[Galaxy S 4 i9500 Original Android Development] AndreiLux:
The to-be-announced new processor is the 5420, it's not a new revision of the 5410. It has the same target clocks as the 5410 but with a properly working CCI to be able to use GTS, and the GPU is replaced with a new generation Mali T62X instead of the SGX 544. It also has some other miscellaneous updates like VP9 encoder/decoder. It'll debut in the new Chromebook this fall.

I already know the differences. In any case - it's not useful in regard to the 5410.
[Galaxy S 4 i9500 Original Android Development] croach246:
Forgive my ignorance, but what are the problems with the i9500 processor. I'm aware they're some issues as someone told me that's why we haven't gotten any aosp roms (something about developers hating the proc.) but I don't actually know what the problems with it are :s

If you have higher freq. You will use more power. For battery you'd Def. Want 100-1600mhz.

But be careful if undervolting and setting min state to 100mhz. You may experience the phone shutting off and taking a while to turn back on (press and hold power button for like 6s). If this happens try slowly increasing the voltage of the lower frequencies (100,200 300)

Using Android tuner I can see that my 100mhz voltage is 900mV. And the phone is stable. (I use 100-700mhz, over clocking the A7cpus to 700mhz)

thanks for integrating the smearing filter. About to flash in a minute. Im a bit curious about the cut off filter, with values set to 4 the smearing is gone but on the other side with full brightness or 50+ brightness the pure black or not pure black anymore,its not that noticeable though but you can see it if you specifically look for it, it would be nice if this cut off filter applies the rgb values only on low brightness level (smearing is noticeable only on low brightness)and resets the rgb values of black back to zero once a certain brightness level is reached?
