Board Features

The ASUS ROG Strix B550-F Gaming is an ATX motherboard which slots into the mid-range of the AM4 market. It combines a solid feature set with dual PCIe M.2 slots, including one capable of supporting PCIe 4.0 x4 drives, while the other is wired to PCIe 3.0 x4. In addition to this is six SATA ports with support for RAID 0, 1, and 10 arrays. Offering a marked improvement over B450 models in regards to memory performance, the B550-F Gaming Wi-Fi supports DDR4-5100 with a maximum capacity of up to 128 GB across four memory slots. For networking, there's a good quality Intel pairing which includes an I225-V 2.5 GbE Ethernet controller, with an AX200 Wi-Fi 6 module which also allows the use of BT 5.0 devices. The boards PCIe configuration includes a top full-length PCIe 4.0 x16 slot, a full-length PCIe 3.0 x4 slot, and three PCIe 3.0 x1 slots.

Touching on rear panel connectivity, ASUS has included two USB 3.2 G2 ports including a Type-C and Type-A port, as well as four USB 3.2 G1 Type-A and two USB 2.0 ports. For users looking to use compatible Ryzen APUs, there's an HDMI 2.1 and DisplayPort 1.2 output pairing, while there's also a USB BIOS Flashback button which allows users to easily update the board's firmware. The onboard audio is taken care of by a SupremeFX S1200A HD audio codec with five 3.5 mm audio jacks and a single S/PDIF optical output. Users can add to the boards USB with an additional four USB 2.0 ports made available via two front panel headers, as well as a single USB 3.2 G1 Type-A header which adds two more Type-A ports. 

Test Bed

As per our testing policy, we take a high-end CPU suitable for the motherboard that was released during the socket’s initial launch and equip the system with a suitable amount of memory running at the processor maximum supported frequency. This is also typically run at JEDEC subtimings where possible. It is noted that some users are not keen on this policy, stating that sometimes the maximum supported frequency is quite low, or faster memory is available at a similar price, or that the JEDEC speeds can be prohibitive for performance. While these comments make sense, ultimately very few users apply memory profiles (either XMP or other) as they require interaction with the BIOS, and most users will fall back on JEDEC supported speeds - this includes home users as well as industry who might want to shave off a cent or two from the cost or stay within the margins set by the manufacturer. Where possible, we will extend out testing to include faster memory modules either at the same time as the review or a later date.

While we have been able to measure audio performance from previous Z370 motherboards, the task has been made even harder with the roll-out of the Z390 chipset and none of the boards tested so far has played ball. It seems all USB support for Windows 7 is now extinct so until we can find a reliable way of measuring audio performance on Windows 10 or until a workaround can be found, audio testing will have to be done at a later date.

Readers of our motherboard review section will have noted the trend in modern motherboards to implement a form of MultiCore Enhancement / Acceleration / Turbo (read our report here) on their motherboards. This does several things, including better benchmark results at stock settings (not entirely needed if overclocking is an end-user goal) at the expense of heat and temperature. It also gives, in essence, an automatic overclock which may be against what the user wants. Our testing methodology is ‘out-of-the-box’, with the latest public BIOS installed and XMP enabled, and thus subject to the whims of this feature. It is ultimately up to the motherboard manufacturer to take this risk – and manufacturers taking risks in the setup is something they do on every product (think C-state settings, USB priority, DPC Latency / monitoring priority, overriding memory sub-timings at JEDEC). Processor speed change is part of that risk, and ultimately if no overclocking is planned, some motherboards will affect how fast that shiny new processor goes and can be an important factor in the system build.

    The Intel I225-V is trash. I had to add a nic to get internet.

    In November I bought Gigabyte x570 Ultra and 3900X and now I plan to buy something for my son for gaming. I'm not happy with Gigabyte despite high grades. My biggest problem with Gigabyte is, as today usually, software. Better to say crappy software. For example every BIOS update deletes previous settings and usually I'm not able to load previous ones - every time remember what I did and set all manually! Oh my God! Not even Windows BIOS update is not clever enough to migrate BIOS settings. Their Windows software is one of biggest craps I ever seen in my life!!!
    How is situation with Asus and others?
    BTW Gigabyte has a crappy software called Easy Tune. When I "overclocked" my CPU via this app my Windows refused to boot! Thanks God I have second installation and was able to delete exes to get Windows booting.

    I've got bad news for you. I upgrade my BIOSs as soon as they're out. I have a Ryzen 5 2400G on a Asus TUF B450M-PLUS GAMING (great combination). I found it nifty I could store the settings so one day I flash my BIOS and then get my optimal settings. Black screen. As far as I can see, the settings are useless from one version of the BIOS to the other. Bummer. From what I can see, it's a new "trend". If anyone knows how to get this to work I'd love to know. I'm about to adjust the memory timings ... many, many settings to change. Upgrading the bios will suck.
  • DZor - Thursday, July 23, 2020 - link

    You see that's reason why 20 years ago I switched from self-built PC to brand names like HP or Dell. I had many HPs, Dells and Lenovos with many BIOS updates and NEVER EVER entered BIOS after upgrade!

    "The usual battleground for a good solid motherboard is in the $200 range" - No, it's not, and we need to stop perpetuating this. A good, solid motherboard needs to be in the $130-$150 range. If your board is coming with RGB lightning, has 16+ phases for power delivery, and looks like one of the Transformers, you've gone beyond "good".
  • PeterCollier - Wednesday, July 22, 2020 - link

    You forgot the "military grade" caps
  • Reflex - Wednesday, July 22, 2020 - link

    I mean, 10-15 years ago that was the range of good solid motherboards. But inflation, reduced volume/slower upgrade cycle and higher base requirements (for signaling, power delivery, etc) would be expected to drive prices up. What we see now is essentially the same as what we saw before once factoring in inflation and market conditions.

    RGB lighting and additional power delivery phases are like dimes in the cost. And most of the R&D is shared with higher end boards. I think it just costs more to make a board now.

    Inflation plus AMD wants to improve its margins. And, now that AMD is offering better CPUs than Intel, motherboard makers want more margin on AMD boards.

    Plus, Zen/AM4 has more demanding board specs than AM3+, in terms of things like voltage precision.

    Board makers will try to push prices higher. It's up to consumers to push back.
  • CardiWAP - Tuesday, August 11, 2020 - link

    Yes please pair your 10700K or 3900X with these boards and see how they fare. I hear Asrock really nailed the $130-$150 range on Z490.
  • Reflex - Wednesday, July 22, 2020 - link

    Not sure if this would help anyone, but the Asus and ASRock boards can actually get their WiFi upgraded. I realized that because I have a ROG Strix B350-I and the integrated Realtek WiFi/BT solution is garbage.

    It seems the 'integrated' solution is actually a vertically mounted M.2 card. If you take the shield off (two screws on the underside of the board) you can pull that card out and put in an AX200 (not the 201, that is specific to Intel chipsets).

    I did the upgrade and it worked perfectly. BT is now reliable and WiFi is faster.

    Not sure if that would help anyone.
