Cooler
A bus that works asynchronously with the CPU is -the expansion bus
PIO
PIO
The CPU runs everything, It's the brain of the whole computer. Usually, having a better/worse CPU will make your computer run faster or slower. Hope this helped!
because of their design
You can but your CPU will probably not go as fast as it should. The motherboard has a system crystal that has a clock. The speed of the clock is called the frontside bus speed. A CPU uses a multiplier to make the CPU go faster. For instance if the frontside bus is 100MHz and the CPU has a multipier of 5, then the CPU will operate at 500MHz. So, if you use a CPU that is larger than what the motherboard requires the front side bus, which is dictated by the type of motherboard may be slower that what your CPU is supposed to see so it will run slower. Hope this helps, if you have any questoins leave it on my message board.
wait state (command for the computer to wait for slower devices)
Slower CPU's do not necessarily use less power, but slowing down the speed of your current processor, will save your battery.
Ram is way slower since its located off the CPU unlike cache, which is on the CPU or very close to it. More Cache=faster processor core.
DMA transfers data directly from the drive to memory without involving the CPU. PIO involves the CPU and is slower than DMA mode.
possibly overheating, make sure thermal paste and fan (if you are air cooling) were applied to the CPU also make sure your motherboard supports all your hardware
Blue screens, computer crashes, an d if it won't start and is it is running slower than usual
