The Russian company Eliptech — an ex-branch of the country’s largest cloud service provider, as well as a “state-controlled bank,” Sber — has developed a new SSI MEB form-factor motherboard, the ET113-MB, which is powered by a Baikal Electronics “sample” Baikal BE-S1000 SoC (System on Chip) to offer 768GB of DDR4-3200 memory.

The Baikal-S CPU has 48 Arm Cortex-A75 cores and is manufactured on a 16nm process. Due to “geopolitical conflicts,” the SoC is no longer produced for the general public and is now being used in Eliptech’s new server motherboard, according to IT Home.

The Baikal BE-S1000 CPU has a base frequency of 2.0 GHz, a maximum boost frequency of 2.5 GHz, and power consumption of 120W. This one-of-a-kind SoC features four-way parallelism and an integrated proprietary RISC-V architecture coprocessor for data management and secure boot. A total of 768 GB of memory can be supported by six 72-bit memory interfaces, with 128 GB in each channel.

This chipset is closely related to the Intel Xeon Gold 6148 CPU and the AMD EPYC 7351. The Intel Xeon Gold 6148 CPU has 20 cores and a boost speed of 2.4 GHz, while the AMD EPYC 7351 CPU has 16 cores and a boost speed of 2.9 GHz.

Eliptech’s new ET113-MB motherboard has four U.2 ports located outside the main board for use in an unusual layout.

External boards cannot be installed on its numerous slots unless the bracket is removed. The ET113-MB also has audio connections, which are not practical for server use but seem more appropriate for a desktop enterprise workstation.

The motherboard includes five PCIe Gen4 x16 (4×4) slots, a single USB 2.0 port, and dual 1 GbE interfaces, allowing the motherboard to control PCIe Gen4 SSDs (x4) as well as multiple SSD or SATA drives. When 2.5- to 3.5-inch drives are connected to the motherboard, the user will notice the limiting capabilities of the Eliptech ET113-MB motherboard. Another limitation is that the SATA connections on the board require L-shaped plugs, further limiting its use.
