Rather yes than no.
The MSI PT880NEO motherboard unfortunately uses an Intel Socket 478, which fits the Pentium 4 processor. An AMD Duron is incompatible with this motherboard, so sorry!
Some Cpu's that use Socket A are Athlon Xp, Athlon Mp, Athlon Model 4 AMD's Athlons and Duron use Socket A, also known as Socket 462. The AMD Athlon and the AMD Duron use a 426-pin socket called Socket A. The Athlon Thunderbird
It is equivalent to Pentium III- and early Pentium 4-based Celerons.
If you have an AMD Duron processor, those run on a Socket A motherboard, which is very outdated in 2011. No major retailers sell processors for such an old socket. I would recommend an upgrade, as Newegg.com has Socket AM3 (the newest AMD processor socket) Sempron processors for as low as $36.99 and AM3 motherboards for as low as $39.99.
It would depend on the motherboard, chipset and CPU attachment type. In most cases, it should work, but in some rare cases it wont.
To laugh at him
It is unlikely that you can replace the motherboard with a new model. The laptop case is designed for that specific motherboard.
No. A Duron does not support AMD64 instructions, which are necessary to run a 64-bit operating system.
There are many types of CPU's.. For Intel, you have socket 775, and a bunch of others I'm blanking on right about now. For AMD, you have AM2. If you're talking about types (e.g. Pentium), you have AMD Phenom, Opteron, Athlon, Sempron, Duron. On the Intel side, you have Celeron, Pentium(s), CoreDuo, Core2Duo, Core2Quads.
Celeron is intels low-cost processor. It is meant for people who do not require a powerhouse CPU, and thus has a bit less processing power than its non-celeron equivalent. AMD's low-cost alternative to the athlon is the duron. So you have a choice between a low-cost intel, and a high-dollar AMD, which is pretty much a draw. When you add the 2gb or RAM, it becomes obvious that the AMD is going to be the better performer.
Yes it will but the speed of the processor will not be displayed prperly. The multipliers will probably hve to be tweaked if the motherboard supports it but you can get it to work. I believe you are talking about a AMD processor usually if a processor ids a 200fsb its a duron and is compatible with all AMd motherboards you can probably go into the BIOS and select the right speed which is usually 100 because on amd processors the fsb is doubled to give you the 200 fsb.
