processor <-compatibility-> motherboard

Someone please tell me that no one has thought of putting an Athlon FX-53 chip into an AMD 64 chipset motherboard. The Athlon FX-53 uses the 939 socket, while the old 64-series (3000+, 3200+, 3400+) use the 754 socket. My question is:

a)If the sockets are PHYSICALLY compatible, how would the computer react to a 939 processor being put into the socket for a 754? Would it be unstable? Would it not boot? Would it overheat due to higher clock speeds?

b)If the sockets aren't even PHYSICALLY compatible, does anyone know of a brand that makes notebook motherboards with a 939 socket?

If I am using the terms wrongly, please tell me, and if what I am suggesting doesn't make sense, or isn't an issue, I apologize for wasting forum space.[xx(]

 

1. The sockets are not physically compatible. Socket 939s use 939 pins, while 754s use 754 pins. There are other differences, including memory controllers, etc.

2. I have posted multiple threads bemoaning the lack of Socket 939 laptops to compete with P4EE notebooks...there are none...for now.

The Socket 754 is not necessarily older. The Socket 939 is an evolution of the Socket 940, which uses only registered RAM, amongst other differences. Socket 940s are actually the oldest, and were introduced with the Opteron server chips, the first to use x86 technology. Socket 754 is the midrange AMD socket, with the 939 being top range and Athlon XP Socket As being the low range.

 

Thanks for the info. I'll definitely check out your threads.
