Suppose you have invested in the AM3+ processor. In that case, it is obvious that you need an AM3+ motherboard that supports your CPU and handles the core and peripheral components efficiently. That said, it is crucial to pay attention to few features while buying it; those features are listed below:

CPU compatibility and chipset compatibility

Only when you have the right socket you will be able to insert the processor into the motherboard. So ensure that the processor socket is AM3+. Also, you must check whether the motherboard can support chipsets like AMD 990X, AMD 980G, AMD 990FX, and AMD 970 Chipset.

Memory support

If you are an avid gamer or do video editing works, you need something more than decent. So check whether the motherboard can support at least 32GB of RAM. If you think you need more, then go for a motherboard with 64 GB of RAM. Adding to this, you must also check the RAM frequencies are supported here. 


What kind of motherboard are you looking for? Small one or a big one? Well, that is subjective. So before investing in the new one, check its size compatibility.


Though most users don't worry about the overclocking person if it is also crucial to check whether the motherboard supports overclocking, when it comes to overclocking, some Intel processors don't support overclocking. Meanwhile, the AMD processors are overclockable as the Ryzen chipsets have to overclock. 


Again this is subjective. If you have a good budget, you can buy a motherboard above 300$, and if you are not ready to invest much, then something between 80$ to 300$ is fine. But do check whether the above features, aesthetics, usable ports, and built-in Bluetooth or WiFi features, are present in the motherboard. 


Another feature that must not be overlooked is the number of slots. In general, motherboards come with three slots—one slot for inserting regular expansion, another one for memory where you can install the RAM modules. And the last one is for high-speed PCI express slots. So the more the number of slots, the more space you have for memory. 


Do AM3+ Processors Work on AM3?

Yes, an AM3+ processor can be used on an AM3 socket and both are compatible with each other. However, though the AM3+ processor is pin-compatible with AM2 motherboards and sockets, they lack some key features and it doesn't work perfectly.

Is AM3 compatible with am3+ and AM4?

Some Asus motherboard manufacturers have designed motherboards that include both AM3 and Am4 mounting holes in their boards and sockets. So these types can easily support AM3+ on AM4 and AM3 motherboards. 

Is AM4 Compatible With AM3+?

Yes,AM4 processor is backward compatible with AM3+. So even if you have an AM3+ motherboard and an AM4 processor, you can easily insert it the AM3+ motherboard and use it.


This was my list of top am3+ motherboards with their features, advantages, and disadvantages. I hope this list helps you choose amongst the best am3+ motherboard in the market. See to that the motherboard which you choose satisfies your expectation and budget. Cheers!!
