Will my CPU fit in an older motherboard.

I have a AMD 4200+ dual core CPU will it go in to a socket 939 board. The board in question is a gigabyte GA-K8N pro sli so is this possable. Thanks christian.

The short answer is no. The AMD 4200+ CPU has 940 pins while the GA-K8N Pro SLI motherboard only has 939. The CPU simply will not plug into the motherboard.

Generally the best thing when upgrading Central Processing Units to do is buy a new motherboard that’s designed for that chip. The number of pins is only one factor in dozens that affect the running of the system.

While upgrading a CPU can give you some performance improvements, far more cost effective upgrades are more RAM, faster hard drives and better video cards.

      Christian, I don’t know. Your best bet would be to talk to the dealer about whether the CPU will fit. My research indicates it won’t but, as you can see, vendors often give contradictory messages.

      Personally, I’d go with a motherboard specific to the CPU.

    3. The Athlon64 X2 4600+ and lower were also made in 939 pin versions.

      If you have a 939 pin 4200+ chip it will fit. Remember to update the BIOS so that your chip is recognized properly.

      I’m running a 4600+ on that motherboard right now.
