Upgrading socket 479 motherboards
Because it's easy to put electrically-incompatible CPU into the socket 479 and thus damage the CPU and/or the motherboard, it is very important that you verify processor compatibility before buying and installing it. Depending on the type of motherboard you have, your upgrade choices are:
● Mobile Celeron / Pentium III-M motherboard: your best upgrade option is a Mobile Pentium III-M 1333. You cannot upgrade to any other mobile processors.
● Celeron M 300 series or Pentium M:
○ If your motherboard supports 533 MHz FSB then the fastest upgrade option is a Pentium M 780. If the Pentium M 780 seems too expensive or difficult to find then consider upgrading to Pentium 770.
○ If your motherboard supports only 400 MHz FSB then the fastest upgrade option is a Pentium M 765. If the Pentium M 765 seems too expensive or difficult to find then consider upgrading to Pentium 755.
You cannot upgrade to Core Solo, Core Duo, Celeron M 400 / 500 series, Pentium Dual-Core Mobile or Core 2 Duo Mobile processors.
● Celeron M 400 or 500 series, Core Solo, Core Duo, Pentium Dual-Core Mobile or Core 2 Duo Mobile (all socket M processors):
○ The best upgrade option is a Core 2 Duo Mobile T7600 or T7600G. The T7600G has unlocked clock multiplier and can be overclocked, but it's very difficult to find.
○ If the T7600 / T7600G is too expensive for you then consider upgrading to slower Core 2 Duo Mobile processors.
○ If you motherboard doesn't support Core 2 Duo Mobile CPUs then your best upgrade option is a Core Duo T2700.
