Over the final yr, we have seen a number of B550 fashions, with the overwhelming majority of those catering to desktop customers and avid gamers searching for a cost-efficient choice to make use of with AMD’s Ryzen processors. Back in January, we reported that ASRock Rack had readied up a brand new B550 mannequin with a extra skilled taste, the B550D4-4L. The B550D4-4L options assist with a broad vary of AMD Ryzen processors, together with 5000, 4000G, and 4000 Pro, with assist for many 3000 collection processors. Some of the board’s core options embody Gigabit Ethernet, assist for 128 GB of DDR4 reminiscence, and an ASPEED BMC controller for administration over a community. We familiarize yourself with the ASRock Rack B550D4-4L and see the way it compares to different AM4 fashions in our newest motherboard evaluate. It got here with a number of surprises as effectively.
ASRock Rack B550D4-4L Overview
Perhaps thought-about one of the vital ‘attention-grabbing’ motherboards based mostly on the B550 chipset is the ASRock Rack B550D4-4L. At the time of writing, the B550D4-4L is the one B550 board recognized to us that features a BMC controller. It is designed to make the most of the ability and high-core rely of AMD’s Ryzen 5000 and 3000 desktop processors, with assist additionally obtainable for AMD’s Ryzen Pro 4000 collection and a few Pro 3000 Processors.
The ASRock Rack B550D4-4L has a transposed AM4 socket and transposed reminiscence slots
Looking on the total design, it’s centered on skilled use and makes use of an ordinary inexperienced PCB. The B550D4-4L opts out of fanciful aesthetics and as a substitute focuses on core performance. Along the highest is 4 reminiscence slots that are horizontally mounted, with assist for as much as 128 GB DDR4-3200, each ECC with supported Ryzen Pro processors and non-ECC reminiscence on the common Ryzen desktop fashions. The B550D4-4L has one full-length PCIe 4.zero x16 slot and one half-length PCIe 4.zero slot. For storage, there’s only one M.2 slot however is just able to supporting PCIe 3.zero x4 or SATA drives, in addition to six SATA ports, 4 from the chipset and two from an ASMedia controller.
The rear panel has 4 Intel Gigabit Ethernet ports, with a fifth Ethernet port for the board’s ASPEED BMC controller, permitting distant entry to the system over a community. Other connectivity consists of an HDMI output to be used with processors with built-in graphics and a D-Sub output (DB15) for the BMC, and 4 USB Type-A ports, two USB 3.2 G2, two USB 3.2 G1. ASRock Rack additionally features a serial connector (DB9). The B550D4-4L additionally has a USB 3.2 G1 header offering an additional two ports, a USB 2.zero header for 2 ports, and 6 6-pin fan headers.
ASRock B550D4-4L Block Diagram
Looking at efficiency, the B550D4-4L was surprisingly aggressive in our computational-focused benchmarks, with the board utilizing AMD’s Precision Boost Overdrive at default. This is above merely doing a great turbo, making the board carry out rather a lot higher than we might assume.
One draw back in efficiency was maybe the reminiscence – it ran at DDR4-3200 CL22 versus different B550 fashions we examined at DDR4-3200 CL16, and it doesn’t matter what values we put in for the latencies, they stayed at JEDEC CL22.
The B550D4-4L additionally proved aggressive in our system testing, with sooner than anticipated POST time efficiency. It confirmed decrease energy consumption in lengthy idle and idle energy states than most boards, whereas energy consumption at load was comparable with different fashions on take a look at. The board’s DPC latency efficiency is not nice, however it does not embody any type of audio codec or audio output regardless.
The ASRock Rack B550D4-4L is a singular B550 mannequin, with not a lot competitors in the best way of server-focused fashions. ASRock additionally has a mannequin based mostly on the propriety deep mini-ITX type issue, the B550D4ID-2L2T, which makes use of the B550 chipset for extra skilled stage operate. Unlike different B550 fashions,…
