Can I run a non-prescott 478 Pentium 4 chip in a Prescott 478 motherboard?

    Yes, you can but it is better to check in the motherboard specifications the type of the supporting procesors.

    Accepted Solution

    Yes - the Prescott-ready motherboards have better voltage regulators to handle that particular cpu.  The non-Prescott socket 478 cpus will be less demanding.  You may want to make sure the FSB of the cpu can be handled, because Prescott E's are 800 FSB and Prescott A's are 533 FSB, so if you put a 400 FSB P4 in there, it will be overclocked.  On the other hand, the 400 FSB cpus (Northwood-A's) are very forgiving and most will run happily at a higher FSB.
