Help With S Tweaks

Hi
I underclock my cpu to 1.4 and GPU to 350
I'm asking for if I must change cpu and gpu voltage too ?

[Q] msm8974pro GPU unvervolting?

I was wondering that is it possible to undervolt our GPU and has it been found yet? My Galaxy S2 had GPU UV and it had a major impact on gaming temperature. If we could control it and CPU voltages then there might be chance to avoid thermal throttling. and maybe increase battery life..

cpu core

I have some question about cpu cores. I searched for them in net but can't find good answer. I posted this thread in s3 neo forum because i want to about cpu cores of s3 neo plus.
what is exactly cpu cores? are they different parts of cpu or they are just different virtually?
Is running one core in 600mhz will use same amount of power used to run two core at 300 mhz?
can one core of cpu can get damaged while the other cores are working fine?
can i run different cpu in different frequency?
if i turn off all core except one will there is a chance that it will get damaged or lower its lifetime?
what i mean to say is does turning off some cores effect the whole cpu of affect some parts of cpu?
does cpu cores use different parts of cpu or every core can use whole cpu?
I am a newbie so if i have done some mistake asking those questions please forgive me because i am new in this forum and i dont know all the rules. and sorry for my bad english.

1) Cores are separate processing units built into the CPU. They are not virtual.
2) Power usage depends more on the CPU itself than the core speeds. I'm not sure about this question, but I would assume that multiple cores would consume slightly more power, but it's more than likely a negligible amount.
3) I would assume so, but I've never heard of such an occurrence. I would think that if one core dies, the whole CPU would be rendered useless.
4) If you're asking whether you can have separate cores running at different speeds, then no. There are apps that let you disable and enable cores though. You can also overclock (or downclock) core frequencies with specially designed kernels (of course you'll have to root your phone). So theoretically you could boost up a 1.4ghz quad core CPU to a 1.5ghz or more, with an appropriate hit on battery life and temperature.
5) I doubt it. But your phone will be very, very slow. And forget about multi-tasking.
6) It'll affect the whole CPU. While cores are separate parts, they are built into the central unit itself, so powering on a core powers the whole CPU.

Oneplus 2 Overclocking Help

I am Noob to Android Development,,, I am having Oneplus 2 and installed Boefla kernel .. When i overclock my A57 cores to 2GHz my phone suddenly turn off and Turn on again after sometime... My question is Snapdragon 810 running on xperia z3+ has 2Ghz A57 ... So I am also want To Keep my phone stable at (A57=2.0 ghz ) .. i dont bother about Overheating or failure... I am Doing this at my Personal Risk.. So Please help me out

The 2 uses the 8994-V2 which is a lower binned chip than what some devices ship with so there is a slight variance in what frequencies and voltages chips can handle as with every CPU. These are not tested above their spec so you may very well have a dud. Another thing to keep in mind is that a higher voltage may help. Use 5mv increments until you no longer see the issue.
That's really it. That said, the 810 heats up enough. Over clocking will only add to that. Not to mention we are already seeing reports of cores dying and everything. So it really isn't something you should do.

Most Exynos vs Snapdragon CPU temps are wrong I think

Noticed that. There's definitely a problem with antutu CPU temperature detection. Thanks for the info
