How to choose the Best AM3+ Motherboard?

Ever wondered what’s the essential part when building a custom PC? Well, it’s the Motherboard & Processor.

If you have already decided about the processor, let’s say in this case you decided about an AM3+ CPU, you will need a better AM3+ Motherboard.

In case you are looking for an AM3+ CPU, you can see here the Best AM3+ CPU.

So, now that you have decided the processor you want to use, your next step is to choose a motherboard for it. A motherboard that can support not only your CPU but also it should be able to handle your peripheral and primary components flawlessly and efficiently.

You also need to consider the size of it, depending on how compact you need. Chipsets are also necessary – means there are a hell lot of things one needs to be aware of.

So, the following are the breakdown points which we consider:

  • CPU Compatibility / CPU Socket / Chipset
  • Memory Support / Overclocking
  • Budget/Price
  • Size
  • Performance
  • Ports needed & additional functionalities

CPU Compatibility / CPU Socket / Chipset

Deciding a CPU is also a time-consuming process, but as you are here, we assume you already have selected an AM3+ processor.

So, when you need to select a motherboard for this type of CPU, make sure that it should support the following chipsets:

AMD 990FX Chipset, AMD 990X Chipset, AMD 980G Chipset, AMD 970 Chipset.

And CPU socket support should be AM3+.

If these are fine, then move on to the next step.

Memory Support

Most motherboards come with the support of a maximum of 32 GigaBytes of RAM, which may not be enough for you if you are a high-end gamer who wants to do a lot of multi-tasking.

So, we recommend that you at least get a motherboard with 32 GB of RAM, or if you need higher than that, then go with a piece that can support up to 64 GB RAM.

In our list, you can see ASRock has the one with this much support.

Not just capacity wise, also check what frequencies of RAM are supported. Do they support overclocking? And in case you have already purchased the RAM, then does the motherboard keep your existing RAM sticks.

These are fundamental questions you should ask.

Next is overclocking: It’s totally up to you. Ask yourself if you will do overclocking or not. Now, the question of whether you need to do it or not is a different one. Most users don’t need to unless they want to. In Intel processors, you need to go with Z370 or Z390 Chipset with CPU having “K” in its name. While on AMD size, it’s much simpler because almost all of their ryzen chipsets support overclocking.

In AM3+ CPU case, motherboards that support best overclocking and are ultimate for such works are Asus Crosshair V Formula-Z and MSI 970 GAMING.

Budget / Price

How much can you spend? Refining this question gives us the question of how much you need to pay.

You can get motherboards from $70 to more than $300 as well. Of course, they vary from all perspectives, including build quality, beauty, ports available, and features such as Wi-Fi and Bluetooth built-in.

Do you need more SATA or USB ports? Are you looking for a “STyliSH” motherboard? Do you “Want” RGB in it?

Answers to All these questions will result in either an increase or decrease in price. And most of the time, it’s the “want” that increases cost rather than “needs’. ‘

So, pay for such features only if you need them as there is a solution for almost everything if you want to get that in the future.

Do you need a small-sized motherboard or a large-sized motherboard? Well, these are the questions only you can answer, and once you have answers to these, you will pretty much have an idea of what you are looking for. This will eventually help you in getting a good one.
