If you aren’t sure of the differences between the B550 and X-570 chipsets, the latter offers full PCIe Gen4 support. It’s for general purpose lanes and CPU chipset uplinks, allowing for quicker performance. When it comes to B550, it provides PCIe Gen3 support for those lanes. 

Although the B550 Extreme4 motherboard is dark-themed with tons of blue, black, and matte features, it comes with adequate contrast. Specifically, these are the plastic and silver-metal highlights with RGB branding which provides efficient contrast. 

Details on the heatsink, M.2 heat shield, rear I/O shroud, and chipset have uniform 45° angles. These all work simultaneously with the PCB’s print for a more effective aesthetic. The matte black finish can be seen on the heatsinks, and these come with polished accents and etching. 

Overall, these appear good with various textures and backlit branding. 

RGB LED lights are present on the B550 Extreme4 motherboard. They can be found in two specific areas and aren’t obstructed directly by two-slot graphics cards. For added bling, consider an RGB RAM or utilise the RGB headers on the board for RGB/ARGB strips. 

We think that it’s generally well-balanced and subtle for most users. But if it isn’t your thing, you can easily switch it off or choose to add more if you want.

When it comes to the layout, it’s consistent and practical with the other current boards from ASRock. The SSDs were positioned adequately from the CPU and GPU hot spots. 

The I/O shield was already pre-installed, and it technically became a regular aspect in gaming motherboards. It’s because this makes installation easier, and these have no disadvantages in the process. 

Beginning at the top-left of the board, when you look at the CPU socket, you’ll see the CPU power connector. Here, the company arranged an 8+4 connector to provide more power to the CPU. This is for times of high-frequency overclocking.

Then looking at the board edge along the right, you’ll see the smaller CPU VRM heatsink present. There are two of these, and they’re made of aluminium and bolted onto the board. There’s a thermal pad being used to guarantee full contact with the MOSFETs that are below. 

At the top of the memory slots of this board, there are two fan headers labelled CPU_FAN1 and CPU_FAN2/WP. Both of these are PWMs that support various PWM pumps and fans today. 

In addition, there are even two RGB headers to the right of the fan headers. One is for a regular 12v 4-pin RGB connector, while the other header is for a 5v 3-pin ARGB connector. These are linked to ASRock’s lighting system, Polychrome Sync RGB. 

An extra PWM fan header sits above the 24-pin board connector and is named the FAN5. 

On the bottom-right section of the board, there are six SATA 3.0 ports present. Just below these is a diagnostic LED panel. The panel offers a code that you can use as a reference manual if you’re having trouble with the board.

Along the bottom edge from right to left, you’ll see the reset, front panel power, and LED connector there.

Next, there’s an onboard reset and power button available. It’s a useful feature to have when trying out a motherboard, and we actually wished all others had these.

There are front panel USB 2.0 headers that support each of the two USB 2.0 ports. You’ll even come across Fans 2 and 3, plus the next 4-pin fan headers. 

Two more RGB headers are present. One is for the 12v 4-pin RGB, while the other is for the 5v 3-pin ARGB.

Rounding out the bottom corner of the B550 Extreme4 motherboard is its front panel HD audio connector. Its audio circuitry is set on the lower-left portion of the board and is concealed by the left heatsink. The only parts exposed on the board are the audio capacitors.

The B550 Extreme4 motherboard can support up to 128GB of RAM in x4 32GB memory modules. You won’t need this for a gaming PC, but it’s more for those into content creation, graphics, or video editing. It’s because these require high-density memory modules that are widely available today.

Overall, its layout is easy to work with since it doesn’t have any user issues. As for building, it’s straightforward and suitable for acquiring a clean cable job, and it’s all thanks to its header placements. 

This time, let’s look at the motherboard’s key features here in our ASRock B550 Extreme4 Motherboard review.

When it comes to online gaming while downloading, this software was able to adequately prioritise traffic. The process wasn’t too scientific so we didn’t have to keep watch on the in-game latency. 

We didn’t experience any issues while streaming content or during online gaming with competing traffic during tests. So with that, we suggest decreasing simultaneous network activities if you’re competitively gaming online.

This is an intuitive system so we didn’t have any problems using it. Everything on it was easy to find, and all elements were labelled clearly which was great. 

We were able to overclock through the BIOS like we’ve been utilising it for years. For updating the BIOS on this motherboard through USB, it was easy and quick, just like how it should be.

Basically, it’s a stable and functional BIOS with a couple of useful utilities for loading storage devices.

This is an easy spot to download different utilities and for keeping these up-to-date. Its “Restart to UEFI” program saves you from hitting the DEL button to access BIOS. 

Both applications from ASRock have been present for quite some time. And, these help make life a bit more convenient without affecting the system’s performance. 

Despite the lack of a heatpipe between the B550 Extreme4’s VRM heatsinks, we didn’t experience any thermal issues. Even when overclocking, the processor never reached high temperatures.

On our open-air test without active airflow, the VRM heatsinks became warm but never became hot. With light active airflow, the air passing over the VRM heatsinks effectively maintained low temperatures.

The A-Tuning app allowed for fan control profiles via Windows. Although basic, the app was intuitive. It has all the important settings and a few presets.

Tests were completed with a Ryzen 3900X.
