MSI mobo K9N_SLI_Platinum supports Athlon 3500+ socket 939 processor?

MSI Computer Corp. - Product
The mobo in the above link specifies...
• Supports Athlon 64 CPU: 3500+, 3800+

So does it support 3500+ socket 939 or AM2 socket? Because in AMD website AMD Processors for Desktops: AMD Phenomâ„¢, AMD Athlonâ„¢ FX, AMD Athlonâ„¢ X2 Dual-Core, AMD Athlonâ„¢, and AMD Sempronâ„¢ Processor I can see 2 types of sockets 939 as well as AM2, but MSI doesnt mention which one and it says generally Athlon 64 CPU: 3500+

Please help me on this. Thanks.

 

Its a Socket AM2 motherboard. A Socket 939 processor will not fit!

 

If a motherboard specifies being a K9 AMD product, it's Socket AM2/AM2+. If it's K8, then it's going to be a Socket 939, maybe Socket 748--but that would have an opening in the center of the socket where there aren't any pins.

 

Never heard of a AMD Socket 748. Theres really no K9, Socket 754-939 and AM2 are K8 and AM2+ are K10. Even though 754-939 and AM2 are all K8s there pin layout make all of them incompatable with each others Sockets. AMD AM2 and AM2+ have the same pin layout but one is K8 and the other is K10 architecture.
