AM3 is known as CPU socket or only socket for AMD processors and AM3+ is adaptation of the AM3 socket. It was released in September, 2011. It comes with 942 pin count, fast serial link of 3.4 MHz, and 0.51 mm diameter of pin socket. Moreover, it has bigger pin holes, and also a CPU cooler for better airflow. Its maximum current support is 145 A with more power quality and regulations.
Another question arouses how does a socket work? The CPU socket you use makes a part called the processor. It becomes a part of your computer by providing necessary power, and also distinguishing a way for the CPU to connect with the other parts of the system. That’s why one has to buy the same socket motherboard with the CPU or else, your PC system will be a mess.
AM3+ is a powerful socket that is compatible with both micro and piledriver architecture. It helps the system with better power delivery as well as reduce excessive heat. As we have said before, a compatible motherboard is a must for the same socket. So, you have to get an am3+ motherboard for the CPU with the same socket.
AM3+ is a better upgrade of the AM3 socket. Though one can make their am3+ motherboard support their am2, am2+, or am3 CPUs by upgrading the BIOS, it will not work. Because there is no DDR2 controller on the CPU. AM3+ is always best as it supports low CPU noise, the system with better qualities. It can handle faster processors well.
Can am3+ and am3 be compatible?
No, They are not and can not be compatible because of the lack of DDR2 memory controller.
Which motherboards are best for am3+?
Motherboard for am3+ socket should be chosen carefully as compatibility is the main weapon. The best motherboards for am3+ are ASRock 990FX Extreme9, ASUS Crosshair V Formula Z, ASUS Sabertooth 990FX R2.0, and Gigabyte GA-990FXA-UD3.
