Description
The ASRock B460M PRO4 is a motherboard for Intel’s LGA 1200 socket using the B460 chipset. ASRock states support for 10th generation Intel Core processors, and the listing names no other generation. The memory type is DDR4 at up to 2933 MHz, and the board carries a 9 power phase design.
Compatibility is what a motherboard buyer needs first, so here it is precisely: socket LGA 1200, chipset B460, memory DDR4. The listing does not state the form factor anywhere, although the PRO4 naming convention in ASRock’s range and the M in the model name conventionally indicate Micro ATX. Buyers should confirm that with ASRock rather than assume it, because case compatibility depends on it. Comparable boards can be found across the motherboards category, including the ASRock B550M Steel Legend on the AMD side and the newer ASRock B760M-HDV for a later Intel socket.
Processor Support And The BFB Feature
ASRock claims 10th generation Intel Core support on socket 1200. The listing makes no claim about 11th generation processors, which also used this socket, so anyone planning an 11th generation chip must check ASRock’s own CPU support list for this exact model and revision, and confirm the shipped BIOS version.
The more interesting claim is ASRock BFB, which the description spells out as Base Frequency Boost. ASRock states that users may install non K series processors on its 400 series boards, including non Z models, and gain a base frequency boost. That matters because Intel normally restricts frequency headroom to K suffix processors on Z chipsets, and BFB works by raising the sustained power limit rather than the multiplier, allowing a locked processor to hold higher clocks for longer under load.
ASRock is honest about the catch: it states that the boost frequency still depends on the cooling system applied to the build. A processor allowed to draw more sustained power produces more heat, so the stock cooler will limit what BFB delivers. Anyone intending to use the feature should budget for a better cooler, and a low profile option such as the Noctua NH-L9i or a larger tower cooler is worth budgeting for.
Expansion, Storage And What Is Actually Listed
The expansion slots are stated clearly: two PCIe 3.0 x16 slots and one PCIe 3.0 x1 slot. On a B460 board the two x16 slots will not both run at full sixteen lanes, since the chipset and processor lane budget does not allow it, and the listing does not state how the lanes are divided. ASRock also lists AMD Quad CrossFireX and CrossFireX support, which is multi graphics card capability for AMD cards.
The storage situation needs stating carefully because it is easy to misread. The feature bullet lists one M.2 slot, specified as Key E for WiFi. An M.2 Key E slot accepts a wireless card, not a solid state drive. Storage M.2 slots use M key or B and M key notches, and the listing does not mention one anywhere.
That means this listing does not document any NVMe storage slot on this board. Anyone planning an M.2 solid state drive must confirm with ASRock before ordering, because building around an assumption here would be an expensive mistake. The listing likewise gives no SATA port count.
Audio And Software Features
ASRock highlights Nahimic Audio, which is a software audio suite rather than a hardware feature. It processes output across headphones, headsets, internal and external speakers, and connections over USB, Wi-Fi, analog and HDMI. The listing does not name the audio codec chip on the board.
The Sound Tracker feature within Nahimic is a visual radar overlay that indicates the direction of prominent sounds in a game. Some players find that useful for locating footsteps and gunfire, and some games and competitive rulesets treat visual sound indicators as an unfair advantage, so anyone playing competitively should check the rules of their game.
The listed operating system support is Microsoft Windows 10 and Windows 11 in 64 bit form.
Highlights
- Socket LGA 1200 with the Intel B460 chipset.
- DDR4 memory support at up to 2933 MHz.
- 9 power phase design.
- Two PCIe 3.0 x16 slots and one PCIe 3.0 x1 slot.
- One M.2 Key E slot for a wireless card.
- AMD Quad CrossFireX and CrossFireX support.
- ASRock BFB base frequency boost for non K processors.
- Nahimic Audio software with the Sound Tracker overlay.
Things To Consider
The B460 chipset does not allow processor overclocking, which is the standard limitation of a B series board. BFB is ASRock’s partial answer to that, raising sustained power rather than the multiplier, but it is not the same as unlocked overclocking and it depends on cooling.
The 2933 MHz memory ceiling is also a chipset limitation rather than a board one. B460 caps officially supported memory speed, so faster memory kits will run at the supported rate rather than at their rated speed. Buyers should not pay extra for high speed memory on this platform.
The listing omits a great deal: the form factor, the rear port list, the SATA port count, the presence or absence of an M.2 storage slot, the fan header count, the maximum memory capacity and the DIMM slot count. Those are all standard motherboard specifications. The Language field reads English five times over, which is a data error rather than a product issue.
This is also an older platform. ASRock first listed the board in May 2020, and LGA 1200 has since been superseded twice. Customer feedback is reasonable at 4.3 stars across 540 ratings, which is a solid sample. Buyers pairing this board with a processor should look at the CPU processors category, keeping in mind that only 10th generation support is claimed here.
Who It Suits
The B460M PRO4 suits a budget or mid range build around a 10th generation Intel processor, or a replacement board for an existing LGA 1200 system whose motherboard has failed. The 9 phase power design and BFB together make it a reasonable pairing with a locked processor and a decent cooler, and two x16 slots give some expansion flexibility.
It is the wrong board for a new build today given the age of the platform, for anyone who wants processor overclocking or fast memory, and for builders planning NVMe storage until the M.2 storage question is resolved with ASRock. It is also wrong for anyone who needs the form factor and port layout confirmed before ordering, since this listing states neither.
