I installed the new version of CPU-Z on a system running Vista. It does not work - it reads a stock 3 GHz CPU as 2 GHz. Even Control Panel/ System is not reading right - it just says "E6850 at 3 GHz", or something like that (when it's overclocked). When the system is set with a 40% OC, CPU-Z reads 2 GHz. If the BIOS says the CPU is running at 4.2 GHz, Control Panel/ System says 3 GHz, and CPU-Z says 2 GHz - which one is right ? I figure maybe Control Panel/ System is just for reading stock voltages, so it's not useful for overclocking. But it would be nice to find a CPU-Z like software that will read the frequencies & everything.
