The ASRock Rack B550D4-4L, a B550 Motherboard with BMC

ASRock Rack, the skilled arm of ASRock, has launched an attention-grabbing B550 mannequin which is aimed on the server and workstation market, however makes use of the mid-range chipset. The ASRock Rack B550D4-4L advantages from help for AMD’s newest Ryzen 5000 sequence of processors, with a BMC controller, help for as much as 128 GB of non-ECC DDR4-3200 reminiscence, and features a single PCIe 3.0 M.2 slot from the chipset.

The primary characteristic on the ASRock Rack B550D-4L, which different B550 fashions would not have, is the inclusion of an ASPEED AST2500 BMC controller, which provides IPMI configuration entry throughout a community. A Realtek RTL8211E supplies connectivity for the IPMI administration, and it additionally contains 4 extra Intel i210 Gigabit Ethernet controllers with RJ45 ports on the rear. Additionally current on the rear panel is a pair of USB 3.2 G2 Sort-A and two USB 3.2 G1 Sort-A ports, with a single HDMI output for built-in graphics, a D-sub output for the BMC controller, and a DB9 serial port. 

Designed to be used in a server and workstation setting, the ASRock Rack B550D4-4L makes use of a transposed AM4 PGA1331 socket with 4 reminiscence slots positioned horizontally alongside the highest. The reminiscence slots enable for as much as 128 GB of ECC and non-ECC UDIMM DDR4-3200 reminiscence, whereas for storage, the board features a single PCIe 3.0 x4 M.2 slot with help for SATA drives too. For standard storage drives, ASRock Rack additionally contains 4 SATA ports powered by the B550 chipset, which helps RAID 0, 1, and 10 arrays, whereas an ASMedia ASM1061 chip controls one other two ports.

The board makes use of a simplistic design, with a inexperienced PCB, which is typical of server-grade and workstation fashions. In direction of the middle of the B550D4-4L is a full-length PCIe 4.0 x16 slot, with a half-length PCIe slot that runs in Gen4 x4 mode with a Ryzen 5000 processor put in. This board technically helps Ryzen 5000 (Gen 4), Ryzen 4000G APUs (Gen 3), and Ryzen 3000 CPUs (Gen 3), together with all Professional counterparts, however ASRock would not go into element about how the PCIe is break up with the opposite processors.

Positioned across the PCB is loads of connectivity with a BMC_SMB header, a TPM header, a PMBus connector, in addition to six 6-pin fan headers. It makes use of a standard 24-pin 12 V ATX energy enter for energy to the motherboard, with a single 8-pin 12 V EPS connector for the CPU. There may be additionally a two-digit debug show for monitoring POST codes.

Though the ASRock B550D-4L will match standard chassis with its ATX dimension, it is primarily designed for 1U chassis and skilled use circumstances comparable to server and workstation methods. ASRock hasn’t unveiled any details about when it may be anticipated to launch at retail.
