Product information - AB350 Pro4, AMD B350 Mainboard - Sockel AM4Motherboards with the AM4 socket serve as the platform for the AMD Ryzen (Summit Ridge) quad-core, hexa-core and octa-core CPUs as well as "Bristol Ridge" and "Raven Ridge" desktop APUs from the A-series with integrated GPUs unlike the old Athlon X4 which came without an iGPU. The advanced AMX X370, B350 and A320 chipsets are aimed at the enthusiast, mainstream and entry-level segments coming with an abundance of modern I/O interfaces and connectors for hardware peripherals, while additional data links are provided by the GPU/APU.
The processor's integrated memory controller supports AM4 motherboards as well as fast and energy-efficient DDR4 RAM in dual-channel mode, as well as specialist ECC error-correcting memory depending on the motherboard. The advanced "Zen" microarchitecture in conjunction with the AM4 platform forms the perfect foundation for high-performance systems in a range of applications.
The Layout of the ATX-Format ASRock AB350 Pro4The ASRock AB350 Pro4 is a motherboard utilising the ATX format and comes with a lightning-fast 16x PCI-Express 3.0 slot and a further PCI-Express 3.0 16x slot connected to the chipset with four lanes. Furthermore there are four PCIe 2.0 x1 slots for other expansion cards and up to 64 GB of DDR4 RAM can be installed into the four RAM slots, operating at a maximum of 2.666 MHz (overclocked). The range of internal connectors includes, among other things, a USB 3.0 header and two USB 2.0 headers for 2 or 4 ports respectively.
Special Features at a Glance:
- 1x PCIe 3.0 x16 for high-end gaming graphics cards
- 6x USB 3.0 Type A & Type C + 1x Turbo M.2 slot PCIe 3.0 x4
- 4x PWM fan ports (4-pin)
- DDR4-RAM up to 2.666 MHz
- Modern UEFI-BIOS including temperature monitoring
Data storage devices such as SSDs and hard drives are managed via four SATA-6G connectors ( incl. RAID support) as well as one horizontal M.2 slot that comes with access to four PCI-Express 3.0 lanes and, consequently, extremely high access speeds of up to 32 Gbit/s. M.2 SSDs measuring from 42 mm to 80 mm in length can be used and furthermore the cutting-edge NVM-Express protocol is also supported. This protocol has been optimised to take advantage of the parallel processing utilised by modern PCIe SSDs. An additional M.2 port with SATA 6G connectivity is also available.
A further highlight of the ASRock AB350 Pro4 is to be found on the reverse of the motherboard, specifically the fact that the motherboard includes a USB 3.0 Type C connector. This new type of USB Type C port is particularly slim and allows connectors to be inserted in either direction. USB 3.0 or USB 3.1 Gen 1 reaches maximum speeds of 5 Gbit/s per port.
Last but not least four fans with a 4-pin PWM connector as well as a pump for water cooling can be connected directly to the motherboard. The I/O shield located on the rear of the mainboard provides connectivity for additional devices and components via USB 3.0 and 2.0, Gigabit LAN, universal PS/2 as well as three audio jacks to connect to the onboard sound of the ASRock AB350 Pro4. The motherboard also supports an integrated APU-GPU (optional) and three display outputs: HDMI, VGA and DVI-D.

Attention: The actual I/O configuration may vary depending on the motherboard. This table only reproduces the basic interface layout. Additional ports may also be possible by means of alternative controllers.
Compatibility Note for CPU Coolers Utilising AMD Socket AM4:Due to the revision in mounting hole distances for the new AM4 socket, CPU coolers with rear mounts will - compared with preceding sockets e.g. AM2(+), AM3(+) or FM2(+) - require AM4-compatible mounting brackets. Please ensure compatibility prior to purchasing. CPU coolers that are attached directly to the retention bracket of the motherboard retain compatibility.
