What is B350?

AMD B350 is a first generation AM4 chipset. 

Before the coming of the AMD B350 chipset to the mainstream tech world, the now wiped out intel motherboards such as the B360 could never allow overclocking. The B350 chipset is capable of overclocking with certain Ryzen processors. Note that even though many motherboards using the B350 chipset can run a second-generation Ryzen 2000 CPU, a good number are unable to undertake the function. You will have to download the required BIOS to connect to the processor.

One limitation of the B350 motherboards is that they don't have Multi Graphics support. The fundamental benefit of multi graphics cards is their ability to increase immersive gaming performance. Without Multi Graphics technology, high-end CPUs like the B350 Tomahawk use tricks to help you win your video games regardless.

When it comes to performance, the B350 matches the X370 motherboards. If you buy this chipset, you will get exciting features like the DIMM slots. The slots allow for expandable memory.

What is B450? 

The B450 is part of the second generation of AM4 socket chipsets from AMD. It is the direct descendant of the B350 chipset. It runs on even lower power than the B350.

This chipset boasts impressive functions such as Precision Boost 2, XFR2, and Store MI technology. You can get a B350 based motherboard from dealers like MSI, ASRock, GIGABYTE, and ASUS.

The B450 is a good performer, and you can use it with several processors. The Ryzen 2000 series, 8-core Ryzen 2700X, and core Ryzen 2600X all work well with B450 chipsets.

The B450 model uses lower power, which decreases the idle power range from 6.8W to 4.8W – a major 2W difference.

Store MI is a unique feature of the B450 chipset. It allows you to install and reverse at any given moment depending on when you want to use it. The Store MI stimulates storage for your PC. It's compatible with NVMe, SATA, and 3D Xpoint disks.

When it comes to cooling, the B450 can accommodate a larger heatsink for better performance.

The MSI B450 Gaming Pro is the standard-bearer when it comes to B450 motherboards. It uses an RT8894A regulator and has 8 semiconductor 4C029 fets. It also includes 4C024 fets.

Similarities and Differences 

There's not much difference between the B350 and B450 chipsets at face value. The B450 came into existence soon after the release of B350 as an upgrade of the previous version.

Below is a breakdown of their similarities and differences that will help you decide between the two models.

B350 and B450 Differences 

Maximum Supported RAM Speed

The maximum supported RAM speed is one of the most noticeable differences between B350 and B450. The B350 supports a top RAM speed of 64GB on DDR3, while the B450 supports up to 128GB on DDR4. 

Storage MI Technology

The B350 lacks the Storage MI technology and Precision Boost Overdrive. The B450 comes with a license for Storage MI. The function of this technology is to improve the storage performance of the B450 chipset. 

Second Generation Ryzen Support

The B350 chipset may need to update BIOS to run the second-generation Ryzen CPU. 

The B450 can support the second-generation Ryzen CPU out of the box.

Note that motherboards that have compatible factory BIOS come with a sticker written 'RYZEN DESKTOP 2000 READY' on the box.

SATA Ports

The B350 motherboard has original support for four SATA ports that can run 6Gb/s. If you take a closer look, you will find two of the ports are positioned at an angle. The two other ports are placed in a vertical line as the motherboard.

The overall number of SATA ports found on the B450 chipset is six.

Four of these SATA ports are found in the chipset while the other two are connected from the inside of the CPU.

The four ports are held together with right angle connectors. The remaining two ports are found at the backside of your motherboards Printed Circuit Board (PCB). 

The two are connected with inexpensive straight connectors. Note that overloading the M.2 slot will weaken two ports.

Fan Headers

The B450 has six 4-pin headers that are divided into three parts. One is for the CPU, another for the water pump, and the remaining four for the system fans.

As for the B350, it has 5 fan connectors divided into four parts. One for the CPU fan header, one for water cooling CPU fan header, one for the system fan/water cooling pump header, and two system fan headers.

The MSI B450 motherboard can work well with Ryzen for its overclocking function and a whole set of new chipset components. 

B350 and B450 Similarities


Both the B350 and B450 are generations of AM4 based chipsets by AMD. They use an AM4 processor socket. B350 is the first generation, and B450 is the second generation.


Both the B350 and B450 motherboards are known to support overclocking. Only the 'A' series of motherboards don't support processor overclocking. The B350 can auto overclock the 'X' series processors. 

On the other hand, the B450 does similar work only that it's AMD's Processor Boost Overdrive facilitates a way better performance with the same Ryzen X CPU. 

PCIe Lanes  

Both motherboards support the original six PCIe lanes committed to PCIe 2.0 slots.

They also share the same PCIe 3.0 separation which provides a single PCIe 3.0 x 16 slot. 

Both chipsets have four RAM slots.

USB Structure

They share original support and a similar USB structure. Both the B350 and B450 chipsets support 3.1 ports.

The B350 motherboard doesn't come with any USB 3.1 (10Gbps) even when it's clear the chipset can support them. 

The B450 has eight USB ports. Two of these support the USB 3.1 Gen2 ports known as Type A and Type C. 

The greatest LAN speed which is recorded at 10/100/1000Mbps is the same for the two motherboards. The quality Audio Channels are at 7.1 channels for B350 and the B450.

Both the B350 and B450 are a near-photocopy of each other.

People Also Ask

The following are some of the questions that most users with a keen interest in tech and gaming often ask. All the questions relate to the functioning of the B350 and B450 motherboards. This section is meant to expand your understanding of the two motherboards further. If your question goes unanswered, you are welcome to shoot it over to us.

Can B350 Run Ryzen 3000?

The B350 chipset has backward compatibility with Ryzen 3000 but will need a BIOS update. The newest X570 series are the only motherboards that don't need updating BIOS. Asus motherboard manufacturers have updated BIOS versions with AGESA 0.072 or 00.70, which supports B350.

Can B450 Run 3600mhz RAM?

You need to set XMP for the RAM that's functioning at 3600mhz. If the XMP is not set, all the RAM in B450 will work at 2666mhz stock. This means that you can't set RAM at 3600 MHz stock on a motherboard.

What Processors Can I Use With a B350 Chipset?

The new generation chipsets enjoy compatibility with second-generation Ryzen 2000 CPUs. With updated BIOS, the B350 can also run the Ryzen 7 2700.

Can B350 Be Overclocked?

AMD's B350 chipsets respond well in achieving automatic overclock on X series CPUs and operate to a certain breadth.

Unlike other cheaper versions of chipsets that are natively prevented from overclocking, your B350 is completely open to enhance overclocking when working with Ryzen processors. 

Can B450 Be Overclocked?

A combination of Precision Boost 2.0 Linear Algorithms and Extended Frequency Range 2.0 allows automatic overclock with AMD B450 that you can use as you please.

You need to note that Intel's Mid-Range chipsets have no automatic overclocking function.


When the tech company I worked for restructured and I ended up jobless, I decided to put the wealth of knowledge and management skills to use somewhere new. I’d checked out a few buyer’s guides on the site in the past and reached out to the previous owner. A few months later, here we are. Now, I get to be behind the scenes, helping people find the best tech.
