Best AM3+ CPU for 2021 – Top Best Picks for Gaming

This article presents the best AM3+ CPU list. But before going straight for the CPUs let’s take a look at the history and compatibility of AMD socket form factors to understand it better.

In 2006 May, AMD introduced a new series of sockets to replace the its older sockets (socket 754, socket 939 that were designed for the Athlon series processors).

Socket AM2 was designed to support the DDR2 memory at the time and as the RAM has developed over the years, so does these cool sockets.

The latest socket in the series is AM3+, which is the successor of the AM3 sockets and supports the DDR3 dual-channel memory.  There are total 4 sockets form factor in this version of AMD:

  • Am2 supports DDR2((dual-channel)
  • Am2+ supports DDR2(dual-channel)
  • Am3 supports DDR3(dual-channel)
  • Am3+ supports DDR3(dual-channel)

Now, some common queries about the compatibility of these sockets with each other. Does AM3 CPU works in AM2 motherboards and likewise.

Here is the breakdown of compatibility between AM2, AM3+, AM3, AM3+ processors and motherboards that goes with them.

  • Socket AM3+ motherboards can be installed with Socket AM3 processors given BIOS supports the processor.
  • Socket AM2+ motherboards can be installed with Socket AM3 processors however only DDR2 memory is supported and BIOS must also support.
  • In Socket AM2 motherboards you can install AM3 or AM2+ processors, given BIOS must support the processor, the FSB will run at lower HT 2.0 speed, and DDR2 memory is required.
  • AM2+ motherboards can be installed with Socket AM2 processors.
  • In Socket AM3 motherboards Socket AM2 or AM2+ processors can’t be installed.

AM3+ CPUs for Gaming and General Operation

AM3+ CPUs provides smooth gaming and general operating experience because of their high level of performance.  Its longevity can be accredited to AMD’s affordable pricing and powerful performance. Despite the new Ryzen series entering the market the AM3+ sales remained high because of its intense operation at higher clock speeds, better cores strength, multi-thread features that kept giving good value to the users.

How to install AM3+ CPU?

Step 1: Take out the motherboard from its box and remove the protective packaging. Place the anti-static bag or foam mat under the motherboard to protect it before laying it down on a flat surface.

Step 2: Gently lift up the socket’s metal lever to prepare the socket to receive a processor. This exposes the AM3+ socket to make it possible to insert the processor. Check the small triangle casted into one corner of the socket, this is the processor alignment symbol.

Remove the AMD processor from its box and plastic clam shell packaging. Take off the protective plastic chip carrier cover by holding the processor by its corners. Inspect the underside of the AMD socket AM3 processor and check the gold pins to ensure none are bent and that no external substance is present.

Clutch the processor by its edges, position the chip so the small gold triangle faces the small alignment triangle moulded into the top of the AM3+ socket. Put the processor gently into the socket, ensuring that its pins align with the socket without any resistance. The CPU should literally drop into the socket.

Final Conclusion

Buying a new computer component is always exciting and confusing. But, once you get the hang of your needs and understand what features are required in your system then you can easily build an efficient system as per your requirement.

Hope this article must have solved most of your queries regarding AM3+ CPUs and their selection. Enjoy building your PC!
