Motherb supports a certain CPU but same CPU isn't on the list of chipset support....

My CPU is Celeron 450
Here it shows the CPU is supported by the motherboard:

(If you click on "overview and specifications" it shows how the chipset supported is P965)


Here is the list of chipsets

Why isn't Celeron on the list?

List of processors compatible with your chipset from the Intel website. Whatever the source for the table was, it isn't accurate
