Note well that you might have to reflash the BIOS with the latest BIOS file in order for a motherboard to recognise and/or run a particular processor.
The motherboard's BIOS will have been programmed to be able to recognise and run all of the processors that its manual says that it can run, but this might not be the case if a faster version of a particular processor becomes available that the BIOS programmers knew nothing about. They would not usually provide support for unknown later versions of the same type of processor, because its hardware requirements could be different, thereby making its installation in the motherboard inadvisable.
For example, if the faster version of a particular make and type of processor becomes available, it could have power or other hardware requirements that exceed the capabilities of the motherboard, and should therefore not be installed.
Therefore, you should always check the motherboard's website for information about a processor if it is not listed as being supported in the motherboard's manual.
