**B Grade** X370 Gaming K4 AMD X370 (Socket AM4) DDR4 ATX Motherboard
B Grade items may have been used, have damaged packaging, missing accessories or a combination of these (Motherboards may be missing I/O shields).
Some items may have scuff marks or slight scratches but should otherwise be an operable product.
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 ATX-Format ASRock X370 GamingThe ASRock X370 Gaming K4 is a motherboard utilising the ATX format and comes with a lightning-fast 16x PCI-Express 3.0 slot that is connected to the chipset via eight lanes. Furthermore there are four PCIe x1 slots available for additional expansion cards. As an X370 motherboard the ASRock X370 Gaming K4 supports AMD's Crossfire- and NVIDIA's SLI-technologies for multi-GPU setups. Up to 64 GB of DDR4 RAM can be installed into the four RAM slots, operating at a maximum of 2.666 MHz (overclocked).
Special Features at a Glance:
- 1x PCIe 3.0 x16 for high-end gaming graphics cards
- 2x USB 3.0 Type A & Type C + 1x Turbo M.2 slot PCIe 3.0 x4
- 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 six 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 110 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.
A further highlight of the ASRock X370 Gaming K4 is to be found on the reverse of the motherboard, specifically the fact that the motherboard includes a USB 3.1 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 2 can reach a maximum transfer rate of up to 10 Gbit/s per port.
Special refinements to the ASRock X370 Gaming K4 include LED lighting. Last but not least the board comes with onboard compatibility for five fans with 4-pin PWM connectors. The range of internal connections encompass two headers for USB 3.0 and USB 2.0 for a total of four ports.
The I/O shield located on the rear of the mainboard provides connectivity for additional devices and components via USB 3.0 and USB 2.0, Gigabit LAN, universal PS/2, a S/PDIF output for connecting 7.1 surround sound systems to the ASRock X370 Gaming K4. The motherboard also supports an HDMI output via the integrated APU/GPU.

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.
