[QUOTE="Big-Foot, post: 524606, member: 40607"] Speaking from the perspective of the manufacturer and the electronics industry as a whole - Socketed IC's are a nightmare for a number of reasons other than those already pointed out; 1) Sockets will ultimately have poor connections as the heat/cool cycles cause the pins and contacts to wear. This results in intermittant failures which are primary causes of failure and warranty returns. 2) Sockets do not transfer heat as well as soldered connections therefore the IC will run hotter as it cannot dissipate as much heat through the PCB as another sink. 3) Sockets are expensive in comparison to soldered connections which causes a direct impact on profit. Now as to the potential to upgrade - that would depend on a number of things. Does the 2.6 gHz chip; * Run at a different voltage? * Have the same form factor? * Have the same pin-out? * Have it's own Clock so as to not need clock input from the motherboard? * Is existing heat sink and available cooling sufficient to support the new IC? Lots of questions.. Few answers... Regards - Randy [/QUOTE]
