XCPUScalar allows you to dynamically scale the processor speed of your handheld Pocket PC 2002, 2003, WM2003 SE, and Windows Mobile 5. It uses the power of the XSCALE or TI OMAP (OMAP850 and OMAP1510) processor and unlocks its dynamic scaling capabilities. You can scale the processor speed from 100 to 728MHz
Pocket Hack Master will make your device feel more responsive when you truly need more performance by measuring the load of the processor and applying a faster speed setting instantly when needed or by lowering the CPU clock when the device is idle
