Tyan recently announced two new motherboards, the Tyan S7042 and S7065 platforms meant for dual Intel Xeon E5-2400 and E5-2600 series CPUs. For those that are unaware, Tyan typically releases derivatives based on a common platform, so these are more akin to motherboard families. One example of a derivative is a version that will have additional SAS ports.

The Tyan S7042 server motherboard is a new lower cost platform in a SSI CEB form factor. The target audience is SMB, home users and web hosts where costs are a key concern. The Tyan S7042 supports dual Intel Xeon E5-2400 series processors. It has a 3+1 DIMM design for each CPU (the Intel LGA1356 platform is triple channel by default) and can accept RDIMM, UDIMM and LR-DIMM modules. Expansion on the Tyan S7042 is provided by 2x PCIe 3.0 x16, 1x PCIe 3.0 x8, and 2x PCIe 3.0 x8 slot (x4 electrical). That allows the platform to support multiple expansion cards. Two GbE ports are serviced by onboard Intel I210 networking. The Intel I210 is the replacement for the Intel 82574L which is expected to reach its end-of-life in 2018. The Tyan S7042 also comes in 10x SATA port or 8x SAS ports plus 8x SATA port configurations.

The company also showcased a new Tyan S7065 platform aimed at the GPGPU market. Using an EEB form factor the Tyan S7065 is quite sizable. The Tyan S7065 supports dual Intel Xeon E5-2600 series processors. Each CPU has 8x DDR3 DIMM slots for a total of 16 DIMMs. The motherboard can accept RDIMM, UDIMM and LR-DIMM modules. For expansion the Tyan S7065 has 2x PCIe 3.0 x16, 2x PCIe 3.0 x8, 1x PCIe 3.0 x4, and 1x PCIe 2.0 x8 slots. Networking is provided by dual Intel 82574L GbE ports. The Tyan S7065 also has 6x SATA ports and 8x SAS ports.

  1. Umm… If the S7065 is really aimed at the GPGPU market, how come it only has two x16 slots? Also, onboard sound?

  2. Yes, I too ask the same question. Nothing much to indicate “GPGPU”. I would be saying that the board is aimed at the “Workstation” crowd.

  3. That was a bit interesting. The GPGPU makes sense. If you look at the x8 slots they are open ended so no issue fitting an x16 card in there. When you look at solutions in that area, most will not even use an x8 slot. Oftentimes for power/ form factor will limit the number of GPUs/ MICs in a chassis. So if you look, the two x16 slots are double width to allow for dual slot heatsinks.

    Now, whether this is the best board in all applications is probably not a title that one would bestow. With that said, my guess is Tyan already has customers buying them for these purposes.
