Base Frequency Boost (BFB) Technology

Who ever said that only K series CPUs and the Z-family platform are capable of being performed with maximum power. Via ASRock BFB (Boost Frequency Boost) Technology, users may install their non K series CPUs to ASRock’s selected 400 series motherboards and enjoy the base frequency boost with the hidden power of processors immediately.

While ASRock BFB breathes life into non K series CPUs, the boost frequency currently still depends on the cooling system applied on your rig.

** BFB frequency performance results may vary between different CPUs and hardware configurations. Frequency shown in this chart is for reference only.


Dr.MOS is the integrated power stage solution which is optimized for synchronous buck-set down voltage applications! Compared to traditional discrete MOSFETs, it intelligently delivers higher current for each phase, thus providing improved thermal result and superior performance.

Premium 60A Power Choke

Compared to traditional chokes, ASRock’s premium 60A power chokes effectively make the saturation current up to three times better, thus providing enhanced and improved Vcore voltage to the motherboard.

Great Board. Priced right. 8/2/2020 3:08:47 PM

Pros: BIOS is well laid out with only one problem, see below. I love that both NVME's are accessible on the front of board. On my last ITX board the NVME died and I had to take apart the entire computer to get to it because the drive was on the back. (FIRST WORLD ITX PROBLEMS). Seems stable with no problems so far. Cooler fitment was tight. I am using a True Spirit 140 Direct and it pushes up against the gskill RGB memory. It fits but only barely. Next time around low profile RAM would be a better idea. Paired with non K 10700 this was an easy build. Cranked the base frequency boost to 125W and it will do all core 4.6ghz with no drama. Temps are mid to low 70's in cinebench.

Cons: Where is the bus speed in the BIOS? I know you cant go far with it but the option to mess around would of been nice. Uninstalled the motherboard software. Seemed useless.

Overall Review: Best bang for the buck z490 imo

Overall Review: -Good overall.

Great board, little, built in heat spreader for M.2 slots. 7/7/2020 1:08:12 PM

Pros: - Benchmarks for CPU on 103% at stock configuration 10700 CPU (no K)
- Everything just works. XMP memory profile kicked in for 3200 low latency memory perfectly.
- Great Integrated Wifi
- Nice improvement on ports and interfaces USB 3.2 for example

Cons: - Noticed some USB 3.2 ports are operating at USB 2.0 speeds. Although they are "blue", the back panel ports integrated into the mobo on one side are running extremely slow speeds. I moved the two external drives over to the other two blue ports on the back plane and speeds increased substantially.

Overall Review: In general, I am happy with the board. The performance seems above par. The BIOS is OK. I expected it to be more configurable. The board does come with some "in OS" performance tools. I ran A-Tuning and it really didn't have a lot of configurable options. I did not see a way to increase the bus speed for overclocking my 10700 in the BIOS. Also, it seemed fairly generic and only shows Performance Mode, Standard Mode, and Power Saving. It does not really explain what changes it will make. This is a bummer as I would like to know what I am changing.

Works well, solid MB 6/30/2020 7:19:34 AM

Pros: - Feels fairly sturdy, reasonably thick, decent heatsinks
- Wifi works well
- Fits ID Cooling IS-60 cooler (just barely, only in certain orientation due to heatsinks)
- Two case fan headers

Cons: - None yet

Overall Review: Using this MB with:
- Fractal Design Node 202 Case w/ 450W SFX PSU
- Intel i5-10400 CPU
- ID Cooling IS-60 CPU cooler
- GTX 1660 Super
- 2x8gb GSkill RAM (low profile heat spreaders)
- Samsung 860 EVO SSD
- Noctua NH-A12x15 case fan x2

With managed expectations, this is a great board. 6/19/2020 3:08:05 PM

Pros: - Price vs. other ITX options
- Memory overclocking
- ASRock's Base Frequency Boost

Cons: - Built to a budget so expect weak OC capabilities on K processors
- Note I/O options before you buy it, it may be lacking in your case
- Offset CPU socket may cause issues with some case/cooler combos (Noctua L12S & NCase M1 incompatible in recommended orientation)

Overall Review: I paired this with a 10700 Non-K because it was the most reasonably priced ITX option that would allow the use of factory overclocked memory. Base frequency boost was a pleasant surprise (required BIOS update) that really wakes up this locked processor (see i7-10700 TechPowerUp review for substantial performance gains), you can set your TDP limit to match your cooling capacity. It's not going to be breaking any overclocking records with K processors or have all of the latest I/O and if you don't need that then this board is solid for the price. If you do need more I/O or a stronger VRM then you'll need to seek higher end options that cost nearly double.

Pros: Works! 2 m.2 slots on the front of the board are super handy, built in bluetooth is awesome, and plenty of ports on the back!

Cons: The only con is that there's no USB c front panel port.

Overall Review: Love it.

"This review for ASRock review rebate program." 6/2/2020 9:20:46 PM

Pros: Looks nice, so far happy with build.

Cons: The GPU slot holding tab snap upon installing GPU. Also a fan termination connector tab not flexible and stayed open.

Overall Review: Happy with the xmp overclocking mode, nice rgb lighting. I wish it had more options for the rgb lighting.
