The B550 Chipset from AMD is the mainstream chipset whereas the X570 is the high-end or enthusiast chipset. ASRock like many other manufactures has released a slew of B550 motherboards in all sizes and price ranges and as I am wrapping up my B550 reviews, they sent over the ASRock B550 Extreme4. The ASRock B550 Extreme4 is a full-size ATX motherboard featuring some of the latest innovations from ASRock. Interestingly, the B550 color scheme is not the standard black or green PCB and added a bit of color to it that flows well with the color of the heatsinks and other accessories on the board. Aside from the B550 chipset, the motherboard includes a 2.5 gigabit network adapter, USB 3 Gen2 ports, 14 phase power delivery with 50A Dr.MOS as well as supporting up to 4733+ MHz memory speeds and continues with their PolyChrome RGB. On paper, the ASRock B550 Extreme4 sounds pretty good so, let’s get into it and see if it is really as good as it claims to be.
ASRock’s packaging has always been colorful and artistic. This helps the manufacture’s products stand out from one another when placed on a shelf at the brick and mortar stores. On the front side of the box, there is blue and pink line ard with the product name in large letters. Moving to the back of the box, ASRock lists out the specifications for the B550 Extreme4. Also included on the back is a clear graphic for which M.2 slot supports PCIe 4.0 and which is PCIe 3.0. There is another graphic showing the included connection type on the motherboards I/O panel and finally, ASRock goes into some of the details on the included features of the motherboard.
Once you’ve opened the box, you’ll be presented with a dual-chamber interior. The upper chamber contains the documentation for the motherboard. In this case, a quick installation guide and software set up guide are included.

A Closer Look at the ASRock B550 Extreme4
The ASRock B550 Extreme4 has a sudo-futuristic look to it with the harsh and sharp angles of the heatsinks on the CPU power delivery and the B550 chipset. The heatsinks use a black/grey color scheme that is offset by the black/blue color theme of the PCB. The motherboard houses two full-length PCIe slots although only the top is electrically configured to run an x16 and two PCIe 1x slots. The B550 Extreme4 also houses two M.2 slots on the motherboard. Thankfully unlike the X570 Taichi that I have only one of the M.2 slots is tied into the B550 chipset heatsink. Also, take note that there is an M.2 Wifi module header located between the two full-length PCIe slots.
Starting at the top left of the motherboard when you’re looking at the CPU socket, you’ll find the CPU power connector. ASRock has configured an 8+4 connector here to help deliver more power to the CPU during high frequency overclocking. During my testing, I only used the 8-pin power connector and did not experience any issues. Following the board edge around to the right, you’ll find the smaller of the two CPU VRM heatsinks. The heatsinks are made from aluminum and are bolted through the board and use a thermal pad to ensure full contact with the MOSFETs below.
Just above the memory slots on the B550 Extreme, you’ll find two fan headers label CPU_FAN1 and CPU_FAN2/WP. Both headers are PWM and can support a variety of PWM fans and pumps on the market. There are also two RBG headers just to the right of the fan headers. One is for a standard 12v 4-pin RGB connector the other is the 5v 3-pin addressable RGB (aRGB) connector and are tied into ASRock Polychrome Sync RGB lighting system. An additional PWM fan header sits just above the 24-pin motherboard connector and is labeled as FAN5.
The right edge of the B550 Extreme4 houses the 24-pin motherboard connector as well as a USB C front panel I/O connector and a front-panel USB 3.0 connector just below the 24-pin connector. An additional PWM fan header is provided and is labeled as CHA_FAN4.
Moving to the bottom right of the motherboard, you’ll find 6 SATA 3.0 ports. Below is the diagnostic LED panel. This panel will give you a code that you can reference in the manual if you have issues with the motherboard. Moving along the bottom edge of the motherboard from right to left, you’ll find the front panel power, reset, and LED connector. Next, there is the onboard power and reset button. This is a handy feature to have when testing and burning in a motherboard and I wish that all motherboards came with them. next up and the front panel USB 2.0 headers that support two USB 2.0 ports each. Fans 2 and 3 and the next 4-pin fan headers that you’ll come across. Two more RGB headers are provided next and just like above, one is for 12v 4-pin RGB and the other is for 5v 3-pin aRGB.
Rounding out the bottom edge of the B550 Extreme 4 is the front panel HD audio connector. The audio circuitry is located on the lower left side of the motherboard and is covered by the left side heatsink. Only the audio capacitors are left exposed.
As I mentioned earlier, there are two full-length PCI express slots on the B550 Extreme4. If you look carefully, you’ll see that only the top slot has connections that run the full length of the slot. This is the X16 slot. The other slot is electrically configured as X4. Depending on the CPU used, the top slot is capable of either PCIe Gen 3 x16 OR PCIe Gen4 x16. The second slot as well as the PCIe slots only run at PCIe Gen3 no matter the CPU. The top M.2 slot is the PCIe Gen 4.0 capable (again, CPU dependent) M.2 slot whereas the bottom is only capable of PCIe gen 3.0 however both are x4 slots. The M.2 Socket in the center of the PCIe slots is a Key E type and supports type 2230 WiFi/BT modules. To be honest, I was a little taken back that this motherboard didn’t include WiFi. It is the first that I’ve reviewed in a while that didn’t.
The rear I/O shield features an HDMI connector for the AMD Ryzen APUs that have an onboard GPU. Next up is a combo PS/2 port and two USB 3.0 ports. The next USB ports are 2.0 capable. The 3rd set of USB ports provided are USB 3.2. One is a type A connector that we’re all familiar with. The lower connector is the newer type C connector. Not only does it allow faster speeds but it doesn’t matter which way you plug it in. The USB 3.2 ports are followed by a 2.5 gigabit RJ45 LAN connector and two more USB 2.0 ports. ASRock has provided WiFi antenna mounting holes for those that choose to put an M.2 WiFi card on the board. Audio I/O is provided by 5 3.5mm jacks and 1 digital optical port.
ASRock B550 BIOS
Upon first entering the BIOS you’ll be dropped at the main tab. This tab details which BIOS version the board is currently running, which CPU the board detected, and the speed. It also shows which memory slots are currently populated. According to the Manual, ASRock recommends that slots A2 and B2 get populated first.
Even more tweaks can be made in the advance tab. Here you can configure onboard devices such as USB audio, and LAN settings, you can change or view the storage configuration options (RAID vs. AHCI)and if you have it available can configure the trusted platform module or TPM. There are even more overclocking options available in the AMD overclocking submenu. This allows you to control and tune PBO or Precision Boost Overdrive and its behavior.
The H/W monitor tab is nice to have and whenever I build a new PC, I take a quick look here to make sure everything is in spec. I was initially a little concerned about the reported temperature of the CPU. This is the package temperature of the CPU. Some motherboards report both package and CPU temperatures and they are different. For example, the Asus B550-I that I reviewed a bit go shows both. As well, I compared screenshots and voltages were identical whereas the MSI B550 motherboard I reviewed showed an idle voltage of 1.476v at idle. I am still a little concerned about a 1.456v vcore at idle when I was told it should be somewhere around 1.38v. However, there has been work done with the Ryzen 3000 series to bring voltages down and the work continues.
One of the things that set ASRock apart in their BIOS from all other manufactures is the fact that you can control the RGB LEDs from the BIOS. There’s not a need to install another application on your PC. The downside is that if you want to change or customize them as they are running, you’ll have to do it in the BIOS. The tools menu offers up a suite of tools that allow you to erase SSDs, for those that won’t secure erase, you can use the NVME sanitization tool, and you can flash the motherboard’s BIOS to the latest version using a USB drive and the instant flash tool.
The security tab allows you to set user and supervisor passwords. These can be used to prevent unauthorized access to your PC. A password can be used to secure the boot of the PC. So that when it is powered on, you’ll need a password to complete the boot. Or you can just secure the BIOS to prevent any unauthorized changes to the BIOS. Say, like at a LAN party when you need a much needed BIO break.
The boot tab allows you to customize the boot options on the PC. You can choose which device you want as your primary boot device as well as a second if that one fails to boot. You can also change the hard drive priorities if needed. You can disable/enable booting from the LAN port however, you’ll need to enable the network stack 1st in the advanced tab. You can also change options such as quick boot and the num-lock on/off at bootup if you so desire.
Lastly is the Exit tab. Here is where you can save or discard all your work you’ve put into configuring the BIOS. You can also load the defaults. Loading the defaults is a good idea after a BIOS update as well as after a failed overclock. You can also choose to override the boot option. For example, if you have two drives with two different OSes installed but do not want to go through the work of editing the GRUB or Windows Boot Manager, you can choose which you’d like to boot from here. Since this system only has one drive with an operating system on it, it is the only option.

Since opportunistic boost clocks are now a thing on both AMD and Intel platforms, 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. Keep in mind that the workload doesn’t stay focused on a single physical core. As needed, the CPU moves the workload around.
The stated boost clock for the Ryzen 9 3900x is “up to” 4.6 GHz and we had a single peak that hit that around the 32-second mark. But for the most part, the 3900x was hovering in the 4500 MHz
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.
Performance wise, the B550 Extreme4 falls within the margin of error as the results are very close throughout the tested motherboards. I included the other motherboards not as a direct comparison but more so as a test to ensure that performance is similar across the board. If one board were to drop performance by a significant margin, then it could be an issue with the motherboard, BIOS settings, etc.
Memory bandwidth tells the same story. ASRock’s motherboard is within range of other boards I’ve tested.
Benchmarks for the ASRock B550 Extreme4 Motherboard
Cinebench is a real-world cross-platform test suite that evaluates your computer’s hardware capabilities. Improvements to Cinebench Release 20 reflect the overall advancements to CPU and rendering technology in recent years, providing a more accurate measurement of Cinema 4D’s ability to take advantage of multiple CPU cores and modern processor features available to the average user.
The Persistence of Vision Ray Tracer, or POV-Ray, is a ray-tracing program that generates images from a text-based scene description and is available for a variety of computer platforms. POV-Ray is free and open-source software.
Multimedia, Compression, and Semi-Synthetic Benchmarks for the ASRock B550 Extreme4
HandBrake is a free and open-source video transcoder to make ripping a film from a DVD to a data storage device easier. Essentially, it can convert video to almost any modern format. The workload video file is a file that I’ve used for years called Sintel. It is a 1.09-gigabyte file that is full HD. I used the Apple 240p preset for this test.
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.
PCMark 10 is a system benchmark for Windows PCs that focuses on common tasks performed in the office. PCMark 10 offers a variety of workloads categorized into four groups. The Essentials group includes web browsing, video conferencing, and app start-up time. The Productivity group includes tests based on spreadsheets and writing. The Digital Content Creation group includes photo editing, video editing, and a rendering and visualization test. The final group, Gaming, includes tests for real-time graphics and physics.
ASRock B550 Extreme4 Sub System Benchmarks (Storage, Audio, and Networking)
“CrystalDiskMark 5 is designed to quickly test the performance of your hard drives. Currently, the program allows us to measure sequential and random read/write speeds.”
To test the on-board audio on the ASRock B550 Extreme4 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.
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 B550 Extreme4 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.
I 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 due to network overhead. Still, I was able to average 1664 Mbps over TCP. UDP on the other hand is connectionless with little overhead. 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 2399 Mbps.

3DMark is a computer benchmarking tool created and developed by Futuremark used to determine the performance of a computer’s 3D graphic rendering and CPU workload processing capabilities. It does this through a series of graphics and physics and or CPU tests.
I test the motherboards on a variety of games. Some are newer, some are older, single-core limited vs multicore. I try to throw different workloads across the short gaming tests in a motherboard or CPU review to see how it handles each test.
Conclusion and Final Thoughts
Initially, I had some strange issues with the ASRock B550 Extreme4 completing the boot when I plugged in the AMD Ryzen 9 3900x. The motherboard wouldn’t always complete the boot and it did not matter if I did a cold boot from power off or a reboot. It would just get “stuck” with the GPU and case fans blasting away at 100%. Typically hitting the reset button during this issue, fixed it and it finished the booting process. After the OS was installed, I updated to the latest BIOS and the issue was solved. This was the one and the only issue I experienced with the B550 Extreme4.
Overall I think the B550 Extreme4 is a good motherboard. I’ve had it up and running on my test bench for a good month now without any issues aside from the initial issue described above. From a performance perspective, there is virtually no difference in day-to-day performance than the rest of the motherboards I’ve tested lately. The B550 Extreme even has me liking the looks of the artwork on the motherboard. It has been a long time since I’ve paid attention to how the motherboard looks overall. Sure, I’ve taken off heatsinks and painted them to match a theme but I hadn’t given much thought to the actual PCB. ASRock’s color scheme overall works for me and I do like it. I do like the fact that the B550 chipset doesn’t need a fan to effectively cool the PCH. The X570 boards that I’ve tested do. When you’re building a water cooled rig to help reduce fan noise while maintaining good cooling performance, the last thing you’d really want is a tiny fan on the chipset cooler adding to the noise.
Given the name Extreme4, I would assume that the motherboard comes with everything and the kitchen sink. However, the kitchen sink isn’t included here. And by the kitchen sink, I mean WiFi. For most of us, it is not a deal-breaker and it still isn’t here. I didn’t do much research on the motherboard before I received it and I assumed it did. However, WiFi M.2 cards are plentiful and cheap enough that it would be easy to order one and slap it in. From a customization standpoint, not including it is great. It means that I don’t have to put up with and remove the manufacture’s choice of WiFi cards and I can choose which WiFi chipset I want. Depending on your outlook and needs, it can be either negative or positive. It is just a matter of preference. For me, it was pretty much neutral however, I did feel it was worth bringing up.
At the time of this review, prices on the ASRock B550 Extreme4 are $159. This is a bit cheaper than the MSI B550 Gaming Carbon WiFi as far as ATX class motherboards go. It’s a good price to get your feet wet in AMD’s pool and I wouldn’t hesitate to recommend the ASRock B550 Extreme motherboard to those looking to build a new system or upgrade an existing one.
