[APP] LeoCpuSpeed v4, control cpu speed & overclock
As some folks had already discovered
by finding some test versions, I've been making an app to control the speed of the CPU. Started out as a test to determine if the "1ghz hack" was genuine or not
, and ended up to be able to control cpu speed and to overclock to some degree.
First of all. This app is NO LONGER BEING DEVELOPED. You can use it as-is and at your own risk. And no, I won't make a WP7 version.
- Updates CPU speed every half second (calculated from the processor registered directly! not from some driver)
- Can stress the CPU to show you that it goes up to 998mhz under load (when idle speed is less than 998mhz)
- Disable autoscaling so that you can control the speed yourself
- Select the speed you want by moving the slider or pressing 768/998 presets
- Automatically disable autoscaling and set speed at boot (via menu)
Notes on auto-apply speed at startup
1) Disable autoscaling
2) Select the cpu speed you want
3) Menu > Apply speed at boot
Notes on overclocking
1) Obviously overclocking is completely at your own risk, as you could harm your device. Luckily, in most cases, your device will just lock up and you'll need to restart your device (remove battery, re-insert and turn on again).
2) The green buttons were the overclock settings that have been succesful 9 out of 10 times. The orange speeds have been succesful like 5 out of 10 times. The red speeds have never worked for me yet.
3) The higher the speed, the more unstable. This is mainly because I don't have a way to increase voltage of the core.
4) Overclocking only works on AC power!
When on battery power, the overclock will work but will be undone within 500 milliseconds by the OS. Something within the OS, or a driver, or the radio rom, enforces the proper CPU speed every 500ms.
Notes on battery
I have seen only very very miniscule differences on battery usage when using 998MHz all the time. You really wouldn't notice the difference if it were at 998MHz all the time, or at 768MHz (default). The only thing you _do_ notice, is that it feels snappier.
Try playing a decent movie in TCPMP or coreplayer with autoscaling on, and try again with autoscaling off and at 998mhz. Huge difference. (Note that some ROMs already have autoscaling disabled and will run at 998MHz all the time, like CleanEX. You won't notice a difference there obviously.)
- For advanced users only: call LeoAutoCpuSpeed.exe with a custom performance level to set that speed (and disable autoscaling if enabled). So, calling "LeoAutoCpuSpeed 12" will set it to 768MHz. And FYI, 18 = 998MHz.
- Add overclock
- Add auto-apply at startup
- Add speed control by slider
- Enable/disable autoscaling
- Initial version (only read cpu speed & stress cpu)
Q: Current CPU speed reads 4294967 MHz, that's amazing!
A: Read here why that happens.
It's at 128MHz or 256MHz when it shows this.
Q: CPU speed is at 921MHz and pressing 998MHz doesn't change it to 998MHz.
A: Click the 768 button, then the 998 button. It'll be at 998MHz now (has to do with the internals of the driver).
