Supermicro H11SSL-NC Rev 2 ATX AMD EPYC Motherboard Review

Supermicro H11SSL-NC Rev 2 Topology

Topology was a major challenge with the EPYC 7001 series. When we add an AMD EPYC 7002 series CPU into the Supermicro H11SSL-NC we see a significantly different picture than with the previous generation:

As you can see, this is all a single NUMA domain which greatly increases performance. Now, AMD has more than twice the number of cores possible in a single socket and single NUMA domain. All PCIe I/O flows directly to the SoC itself, instead of through a PCH as it does on Xeon systems. Here is the block diagram.

What you are seeing here is the PCIe I/O that would go through the PCH and second socket on an Intel Xeon system all connect into a single CPU socket on the Supermicro H11SSL-NC instead.

Final Words

Supermicro will release a H12 generation motherboard after this review goes live that supports PCIe Gen4. Still, the vast majority of hardware today supports PCIe Gen3. If you need to build a server using today’s components, then the Supermicro H11SSL-NC Rev 2 makes sense. It will be less expensive.

The impact of the Supermicro H11SSL-NC Rev 2 is simple. This is a platform that offers more performance, and lower cost per core than dual Intel Xeon platforms all in a single socket motherboard. The ATX form factor allows the Supermicro H11SSL-NC Rev 2 to be used in server chassis that cannot fit E-ATX or proprietary motherboards. That greatly enhances the potential deployment scenarios for the system.

Overall, Supermicro did an excellent job making a PCIe Gen3 platform for the AMD EPYC 7002 “Rome” series. It still needs a Gen4 version for those customers that want to take advantage of that feature at a higher cost.

  1. Arrived two days ago! Today the Case was dropped by DPD. Tonigh i will start to move the system to the new board.
    Would love to see how Epyc 7001 perform on this. Especially my 7551p…

  2. Does the board support Bifurcation?

    And is there any single socket EPYC or TR boards that have 7 full 16 slots? Render farm with this chip would be a nice build.

  3. I would avoid this thing. Have one. You CANNOT flash it to IT mode. Stuck with it in IR. Wrote Supermicro asking for some sort of documentation or assistance and basically got the cold shoulder. Very disappointing.
