How the picks were chosen
We searched the catalog for motherboards with an SP3 socket and found three listings. We included all three because the pool is small. We compared the socket type, memory type, and form factor as listed. Prices are live and read from the store listing, so they may change. None of these boards was tested by our team. The selection is based solely on the specifications provided by the seller and the brand's published information.
Picking the right one for you
Understand the SP3 socket
The SP3 socket is used by AMD EPYC server processors. It supports high core counts and large memory capacities, but it is not compatible with consumer Ryzen CPUs. Check that your chosen processor matches the socket type; all boards in this guide are built for SP3.
Check memory type
Older SP3 boards may use DDR4, while newer ones could support DDR5. The Supermicro H12DGO-6 lists DDR4 support, but the other two do not specify memory type. If you already have RAM, verify the board supports it before purchasing.
Consider the number of CPU sockets
Dual-socket boards allow two processors to share memory and I/O, which can double core counts for virtualized or compute-heavy workloads. The H12DGO-6 and H11DSi-NT are dual-socket, while the H13SSL-NT-B appears single-socket based on its lack of dual-socket mention, though this is not confirmed.
Look at form factor
ATX boards fit most standard server cases, while other form factors like E-ATX require larger enclosures. The H12DGO-6 is the only pick with a stated ATX form factor. If you are building a custom chassis, confirm the board size and mounting holes.
Evaluate bundles carefully
Some listings, like the H11DSi-NT, include processors as part of the package. Bundles can save time and often cost less than buying parts separately, but they tie you to specific CPUs. The other two options require you to source processors yourself.
Think about expansion and manageability
Server boards typically support multiple PCIe slots for GPUs or network cards. The listings here do not specify the number of slots or remote management features like IPMI. If you need advanced administration, use each board's official product page or contact the seller for details.
Questions
What is an SP3 socket?
SP3 is a CPU socket designed for AMD EPYC server processors. It supports high numbers of cores and large memory capacities, but it does not accept consumer Ryzen chips. All motherboards in this guide have the SP3 socket, so they are compatible with EPYC CPUs that use this socket.
Which AMD processors use the SP3 socket?
The SP3 socket is used by AMD EPYC 7001, 7002, and 7003 series processors. These CPUs are designed for servers and offer 8 to 64 cores per socket. The H11DSi-NT bundle includes two EPYC 7K62 processors, which are part of the 7002 series with 32 cores each.
Can SP3 motherboards use DDR5 memory?
Most SP3 boards from earlier generations support DDR4, while newer models may support DDR5. In this guide, only the Supermicro H12DGO-6 explicitly lists DDR4 support. Always check the board's memory type and maximum capacity before buying, especially if you already have RAM.
Do these motherboards include processors?
Only the H11DSi-NT bundle includes processors, though the exact condition is not specified. The Supermicro H12DGO-6 and H13SSL-NT-B are bare boards and do not come with CPUs, so you will need to purchase AMD EPYC processors separately to complete your system.
