Just out of curiosity, do you know for a fact that your CPU is 450 MHz? That may seem like a dumb question but many a CPU has been sold at its max overclocking capacity, rather than its actual speed. Unfortunately, I see that type of thing all the time. If you have a users manual for your system or better yet, your motherboard, it will show you where any jumpers are located that control the CPU speed. The manual will also point out any Bios settings where adjustments can be made. Do you happen to know the make/model number of your computer system or motherboard? I'd be happy to help you locate additional information for your particular system.
