สำหรับคนอยากแรงนะครับ. แต่ต้องแบกรับความเสี่ยงกันเองครับ.

Not so long ago I bought myself on ebay navigator-based SIRF Atlas5. In performance, it was stated frequency of 600 MHz CPU. On arrival it was found that in fact the frequency of 500 MHz CPU. Moreover, commissioned a little later the same navigator, but with bluetooth and has a frequency of 400 MHz at all. At the forum there are people who have Atlas5 rate even lower.
All this, and even your own curiosity spodvigli me to write programmuliny to change the frequency Atlas5. On the hands there was a Datasheet on atlas4. Assuming that the management of frequencies it should differ little from him and decided to draw on. As it turns out there are differences, but not fundamental. If anyone interested, I will describe them later.
As is known to have access to external registers in CE6 kernel driver needed. That's it, and will establish us in the first place. Copy the archive file in the root ClkDrv.dll Resident Flash and add to the registry information from a file ClkDrv.reg, for example by using RegEdit. Dll-ku can be placed in another place, but then you need to edit the appropriate line in ClkDrv.reg.
Once the information is added to the registry, you can run AtlasOC.exe. Once launched, a dialog box will appear controls frequencies.
So look rate my Iphone Style Default:
And so, after increasing the frequency of
About how it works and what it means I'll write later
Still want to write about CETree_SysMetrics - a program for measuring performance. Its principle of operation is to measure the number of operations per unit time. But as a timer, use the system timer, which itself depends on the system frequency, which we change. Therefore, to measure performance, it does not fit. For example, I reduced the incidence of two. All this begins with good brakes (easily visible to the eye), programmulina works twice as long, but persistently shows 400 mips/12 mflops. But if we reduce the system frequency (increase the divisor) and leave the CPU frequency the same, programmulina generally can not count how many MIPS as much as 26 shows mflopsov
Added the ability to overclock memory (by increasing the frequency PLL2). Disclaimer: The memory is always tied to PLL2
Added ability to save settings to a file and read from a file. Added ability to run without the GUI. Line start: "AtlasOC.exe-s filename" where filename can be either an absolute path and file in the directory where the program starts.
For example AtlasOC.exe-s atlasoc.clk or AtlasOC.exe-s \ SDMMC \ atlasoc.clk
Atlas4OC.rarAtlas5OC.rarPS: While not quite figured it out why after running AtlasOC.exe flies off the screen calibration and screen as a band. Dividers And I originally others.
Effect clearly is, but not everywhere. CETree_SysMetrics vaobsche not responded to the acceleration factor of 2, the same 300Mips and 9.490041Mflops.
PPS: The line running to MortScript should look like this:Run ("\ ResidentFlash \ AtlasOC.exe", "-s atlasoc.clk")
จัดไปหนัก ๆ
