Dual-socket EEB server board
The ASRock Rack EP2C621D16-4LP is a dual-socket EEB motherboard built around the Intel C621 chipset for LGA 3647 Xeon processors. It targets data-centre deployments that need high core counts and large memory capacity in a 12 by 13 inch form factor. Sixteen DDR4 DIMM slots and fourteen SATA3 ports provide the density required for virtualisation hosts and storage nodes.
Workload fit and limits
This board suits operators who need two Xeon Scalable CPUs, quad-channel memory and multiple PCIe 3.0 x16 slots for accelerators or network cards. It is not for builds that require more than two sockets, integrated networking faster than 1 GbE, or a form factor smaller than EEB.
Deciding specification
The sixteen DDR4 slots set the maximum memory capacity and channel population rules for the platform. Populating all slots with supported RDIMMs or LRDIMMs determines whether the system meets the memory footprint of the target workload.

คำถามเกี่ยวกับสินค้านี้
How much memory can the board actually address when all 16 DDR4 slots are populated?
The board provides 16 DDR4 slots in a quad-channel layout; maximum capacity depends on the DIMMs installed and the processor memory controller.
What does the M.2 slot share bandwidth with and how does that affect drive choice?
The M.2 slot shares two SATA3 ports; using a SATA M.2 drive disables those ports while an NVMe M.2 drive leaves them free.
What clearance does the EEB 12"x13" form factor need in a chassis?
The board measures 12 by 13 inches and requires a chassis that supports the EEB form factor with matching mounting holes.
