But, with the carbon series, the goal is not just about looks, performance reliability, and stability all matter as well. In the past, I’ve had great success with other MSI Carbon boards. MSI has packed the latest technology into this motherboard and includes dual M.2 slots with heatsinks, WiFi 6, 2.5 GbE LAN, a 12+2 phase power design helps to get the maximum performance from the latest and greatest CPUs from AMD and support for up to 5100 MHz DDR4 memory.  On top of all that or rather under it, the motherboard is built on a 6-layer PCB with 2 oz of copper to ensure long-lasting performance and stability. Is the new B550 version a worthy replacement? Read on to find out.



Considering that sports cars and supercars contain a lot of carbon fiber, it is only natural that MSI includes a stylized graphic on the front of the box. The chipset, socket, and supported CPU types are also listed on the front of the box and it would be hard to miss. On the back of the box, MSI featured a graphic of the motherboard and the I/O panel. The features and specifications are also listed on the back of the box.


Lifting the lid on the box reveals a two-compartment box. The motherboard wrapped in an anti-static back sits in the top compartment and the manuals and accessories are housed in the lower compartment.


Included in the accessory kit is a user manual, quick installation guide, SATA cable labels, MSI case badge, produce registration card, driver installation DVD, case screw guide, 2x SATA cables, a thermistor cable, an RGB LED extension cable, and the MSI product catalog.

A Closer Look at the MSI MPG B550 Gaming Carbon WIFI

The MSI B550 Gaming Carbon WIFI is a standard ATX board meaning that it measures at 12in x 9.6 inches. The motherboard features two aluminum heatsinks over the VRM for the CPU. A plastic cover accompanies the left heatsink and provides a cover to the top of the I/O panel. Two aluminum heatsinks are included for the M.2 SSDs below as well as an aluminum heat for the chipset. Unlike the X570 chipsets, the B550 doesn’t require active cooling and thus doesn’t contribute to the overall noise level of the PC.

The area around the CPU socket is fairly clear and there shouldn’t be any components on the board that will interfere with a CPU cooler installation. MSI uses a stepped style heatsink for the VRM cooling so, the parts of the heatsink that are closest to the CPU socket are still low enough that most CPU coolers on the market should fit without an issue. However, always check beforehand just in case.

In the middle of the B550 Gaming Carbon WIFI, you’ll find the PCIe slots. There are two X16 slots. The top slot operates at x16 speeds whereas the bottom slot only operates at x4. Intermixed with the X16 slots are 3 PCIe x1 slots. At the top of the PCIe slots is an aluminum heatsink that cools the 1st M.2 slot. This slot supports PCIe 4.0 x4. The lower heatsink covers the second M.2 slot and supports PCIe 3.0 x4 and comes from the B550 chipset. Finally, a carbon fiber wrapped accent piece with the MSI dragon is attached to the aluminum heatsink for cooling the B550 chipset.

MSI B550 Gaming Carbon BIOS

MSI’s BIOS looks and feels the same throughout their product lines. Which, is a nice touch. I know a lot of other vendors do as well. Some however have a different look and feel depending on the motherboard. With that said, the BIOS is starting to feel a little long in the tooth and while it works just fine, it may be time for some updates.

The first time you enter the BIOS on the B550 Gaming Carbon, you’ll be presented with “EZ Mode” while there’s not a lot of tweaking options here, you can get the system up and running quickly. You can turn on A-XMP, AHCI/RAID, configure storage, and a host of other options.

Since now both AMD and Intel use opportunistic boost clocks for the CPUs, for every CPU review, I run a single-core test in POV-Ray and capture the clock speeds for 60 seconds to verify the motherboard and CPU can hit the advertised speeds.

MSI MPG B550 Gaming Carbon WIFI Motherboard Review

As you can see, the MSI B550 Gaming carbon hovers around that 4503 MHz mark with a couple of peeks into the 4.6 GHz. This is actually a pretty decent boost. Other boards I have tested show a slightly less average boost clock.


Testing and Performance


AIDA64 has a set of several 64-bit benchmarks to measure how fast the computer performs various data processing tasks and mathematical calculations. Multi-threaded memory and cache benchmarks are available to analyze system RAM bandwidth and latency. Benchmark pages of AIDA64 Extreme provide several methods to measure system performance. These benchmarks are synthetic, so their results show only the theoretical maximum performance of the system. The AIDA64 suite has various benchmarks for CPU, FPU, GPU, storage, and memory testing.

In both CPU and FPU testing with the B550, it keeps up with the more expensive X570 chipsets. This is a trend repeated throughout the benchmarks.

The 7-zip benchmark shows a rating in MIPS (million instructions per second). The rating value is calculated from the measured speed, and it is normalized with the results of the Intel Core 2 CPU with a multi-threading option switched off. So, if you have a modern CPU from Intel or AMD, rating values in single-thread mode must be close to real CPU frequency. There are two tests, compression with the LZMA method and decompression with the LZMA method. Once the total passes reach 100, the score is taken. 7-Zip gives the resulting score for decompressing, compressing, and an overall score.

Audio Testing

To test the on-board audio on the MSI B550 Gaming Carbon WIFI motherboard, I use the Rightmark Audio Analyzer benchmark. To test the onboard audio of any motherboard, I follow the guide on RMAA’s site that talks about how to review Asus Xonar D2 in RMAA 6.0.5.

The built-in audio solution is perfectly adequate. It is in the range from what I’ve seen from other motherboards from MSI in the past as well as other manufacturers.


Network Testing

For network testing, I have a QNAP QSW-1208-8C 10 GbE switch that is capable of Multi-gigabit switching. This means the ports on the switch will negotiate at 1 Gb/s, 2.5 Gb/s, 5 Gb/s, and 10 Gb/s. Since the LAN port on the Strix B550-I is 2.5 Gb/s capable I used this switch and another PC that is 2.5 Gb/s capable and tested using Performance Test 9’s network testing tool. For Wireless testing, I have a WIFI 6 Access point connected to the same switch and is connecting at 2.5 Gb/s. The same wired test PC is used.

test both TCP and UDP connections. TCP connections are connection based. This means the server and client talk back and forth to each other for every packet. Typically TCP will never reach line speeds. Still, I was able to average 1458 Mbps over TCP. UDP on the other hand is connectionless. This means the network clients (either server or client) send traffic without any back and forth communication. If the packet gets there, it gets there. UDP typically is a good indication of line speed and it shows here. My testing averaged 2057 Mbps. Wifi 6 is fast. With TCP I was able to reach an average of 581.3 Mbps and UPD averaged a bit faster at 667.1.

Conclusion and Final Thoughts

The MSI MPG B550 Gaming Carbon WIFI is a fine motherboard. From the packaging to the installation, it all just works. MSI may not have the fancy features of other motherboards and honestly, it doesn’t really need it plus it saves you a couple of bucks here and there. The more I dive into the B550 motherboard the more I like them as well, the more I dive into MSI’s product line the more I like them as well. However, I’m not really impressed with EVERYTHING on the MSI B550 Gaming Carbon WIFI. The biggest complaint that I have is their BIOS GUI is getting a little long in the tooth and my opinion looks a bit dated. I think it needs a refresh. However, it does work and it is adequate for the task at hand.


MSI MPG B550 Gaming Carbon WIFI Motherboard Review

From a performance aspect, the MSI B550 Gaming Carbon met expectations. It was right in line with the X570 board from ASRock and the B550 motherboard from Asus. I do appreciate the fact that the MSI board tends to have a higher opportunistic clock than the other boards and results in slightly higher performance. It is a very slight performance increase but I’ll take any that I can get. My sample of the Ryzen 9 3900x does not overclock at all and it never has on any board that I’ve put it in. I did not win the silicon lottery with this CPU so I do not even attempt overclocking. There wasn’t one feature that stood out from the rest. All of them were just good. This motherboard is good all around.

The MSI B550 Gaming Carbon WIFI may not be for everyone. Some don’t like the carbon fiber accents and some may not like the MSI Mystic Light. I do have to say that Mystic Light is one of the less intrusive RGB lighting controls. The lighting on the board is done very tastefully and is easily shut off for those that don’t want it. MSI included enough fan headers and should please most consumers. The other thing that I appreciate is the M.2 slots are not covered by the entire chipset heatsink. Having individual heatsinks is a must if you swap out parts often.  Pricing on the MSI B550 Gaming Carbon WIFI as of this writing is $239. This isn’t the bottom of the barrel pricing but it’s not caviar pricing either. I feel that the price for this motherboard is decent. There are other boards for similar prices. The motherboard market right now is extremely competitive and we as consumers win when that happens. Overall, I would happily recommend this motherboard if you’re looking to upgrade or build a new system. AMD’s ecosystem continues to impress and MSI is right along with it.
