Dell 384-BBSR PowerEdge SP3 System Board vs Supermicro H12SSL-CT Server Motherboard

These are different kinds of parts, not two versions of the same thing. The Dell 384-BBSR is a replacement board for a specific EMC PowerEdge chassis, so it only makes sense if you are repairing that server. The Supermicro H12SSL-CT is a standalone ATX board you can build a single-socket EPYC 7002/7003 server around, with dual 10G LAN and an onboard SAS controller. For a new build or a general-purpose server, the Supermicro is the clear pick; for a PowerEdge repair, the Dell board is the only one that fits.

• Choose the Dell 384-BBSR if you are replacing a failed board in a supported EMC PowerEdge server and need the exact 16-DIMM SP3 part that drops into that chassis.
• Choose the Supermicro H12SSL-CT if you are building or upgrading a single-socket EPYC 7002/7003 server in a standard ATX case and want dual 10G networking and SAS on board.
