SetCPU is a great program, does what it says, author is good and keeps it updated. I have nothing against SetCPU, the author of it, or anyone who uses it. In fact, I have the purchased version, why would I pay for it if I thought it was garbage? I wouldn't. I also agree with you when you say it allows more control over our phones.

The problem with it is:

1) Too many people are messing with it and do not know what they are doing. They are just trying to mimic what they see others doing, which may or may not work for them. This is the biggest, most common, and most damaging problem with SetCPU.

2) It can cause problems and/or hurt battery life if it is set incorrectly.

3) You do not know it is set correctly or not until you use it for a while. You may be also permanently damaging your phone as you have it set wrong and not even know it (Too high of an overclock for your particular phone, phone getting too hot in a warm environment, etc.)

4) It can cause problems for people who are trying to switch ROMS and forget to disable it.

5) King himself told people not to use it because it can interfere with HAVS. Though yes, one adjusts frequency, the other voltage, they can interfere with each other. HAVS will read the lower voltage and set itself different than if you are at stock clocks, this can cause either problems or quicker battery drainage. Maybe both. Both are going to try ramping up and down constantly and this is what causes the problems and the quicker battery eating.

6) If you set your CPU too high or low and it locks up and you happened to set it to "Save settings on reboot" you may have to do a full wipe and reinstall. Your phone may even be fine for a few days, then decide it does not like the settings you have and then this problem emerges.

7) This is not a computer with a fan cooled case. It is enclosed and there is no easy way to modify the cooling system. Even with a computer it is always recommended to upgrade the cooling system from stock if you wish to overclock. Most are only able to achieve a measly 10-12% overclock. It will test faster, naturally but in use it is not going to blow you away. In fact, if it seems much faster it is more of a placebo, you will barely notice it, if you notice at all. Notice the FPS only goes up 1-3 points? You are not going to see that with your eyes.

8) I notice most people experiencing problems also happen to be running SetCPU. Coincidence?

9) For that measly 10-12%, you can running your phone 10C more or hotter, that is a BIG difference in heat.

So, as great of a program as it is, it is also dangerous in the wrong hands or if it is set wrong, purposely or accidentally. User error is a big issue with it.

I was a an avid user of it myself but now I do not want to use it and will advise others not to because frankly it is not needed unless you want to impress people with your Linpack score or want to see what your phone can do. Overclocking kills battery faster, common sense. Also, the candle that burns twice as bright lasts half as long, the long term effects are unknown.

But hey, if you want to use it...do so. Anyone can do what they want, I never said what I said was the end all/be all. Just remember if you have problems, it is one of the first things you want to disable to troubleshoot.

Hopefully this explains better why I advised not to use it. In case anyone thinks I have animosity towards it or questions why I advised not to use it.

HI. I'm using Kings NEW #11 where he mentions the following.

Kernel #11

- HAVS is now OUT. We are not currently using it

- Using SVS for voltage regulation at the moment

So...does this mean SetCpu will play nice with #11 now?

I only have one profile in SetCpu, that is Screen off Min: 245 Max:499

I'm actually getting damn good batterylife with this set up. (Oh..on main, Scaling "Conservative" at 998 and 245.

with moderate to heavy use, I'm getting 10 hrs easy.

What do you think?

Thanks!
