ASRock’s C621A WS, A Powerful Motherboard for Xeon W-3300 Workstations

Asrock WS motherboard

With the arrival of Ice Lake CPUs with up to 38 Cores, Intel has taken workstation computing to a new level. Xeon W-3300 family can be clocked up to 4GHz and can support up to 4TB of ram. To keep up with these high-end CPUs, ASRock has released the most powerful C621A WS motherboard for high-end workstations.

The ASRock C621A WS can support a Xeon W-3375 processor, 2TB DDR4 memory, x4 PCIe 4.0 x16 graphics card, and plenty of storage. If you need a future-proof workstation motherboard, the ASRock C621A WS perfectly sits in that scenario. It’s more promising, expandable and reliable as compared to other workstation mobos in the market.

Most of the Xeon W-3300 chips come with a TDP of 270W, and this motherboard comes with a 7-phase digital VRM to handle that level of power.

To make this WS motherboard more expandable and compatible, ASRock has opted for an LGA4189 Socket P+. Only limited CPU coolers are compatible with such a narrow CPU socket. However, this gives way to add more peripherals to your motherboard. And if you are up to add more ram and graphics cards, this might be the best motherboard for you.

Expandability Options on ASRock C621A WS Motherboard

The ASRock C621A WS comes with eight DDR4 DIMM slots to accommodate memory up to 2TB. And to achieve this much amount, this mobo makes use of RDIMM, LRDIMMs, and Intel’s Optane modules. To add more graphics cards, you get access to x4 PCIe 4.0 x16 slots. Also, there are x3 PCIe 4.0 x8 slots for adding enterprise-grade storage devices, FPGA accelerators, and some useful peripherals. Moreover, for faster data access, there’s x1 M.2-22110 slot for SSD, SATA, and one Mini-SAS connector slot.

For rapid connectivity, the ASRock C621A WS has come with two 10 GbE ports favored by the Intel X710-AT2 chip. In addition to this, there are x2 10 GbE ports monitored by the Intel I210 chip as well.

For faster data transfer, the ASRock C621A WS has x2 USB 3.2 Gen 2 Type-A ports at the front and two USB 3.2 Gen 2 Type-C ports at the back panel.

Finally, the ASRock C621A WS has enough rear panel I/O, storage, and expansion capabilities to stand out in the race of modern workstation builds. It can handle plenty of computing and graphical power needed for an ultra-high-end workstation PC. You can store a hundred terabytes of data if you connect this motherboard to a high-performance NAS device. What we really miss on this motherboard is the support for Thunderbolt 4 and Wi-Fi 6e. If ASRock includes these two features in the future versions of this motherboard, then it would be fantastic. Also, if the future models of this motherboard can support dual CPUs, it will have no parallel in the workstation industry.
