Gigabyte has released a server with 48 DDR5 slots – up to 24 TB of RAM in a standard case

Gigabyte showed servers based on the AMD EPYC Genoa hardware platform, which are distinguished by the presence of 48 slots for DDR5 RDIMM RAM modules. Models R183-ZK0 and R283-ZK0 are made in standard 1U and 2U formats, respectively. Senior new

Gigabyte R283-ZK0

Both systems are built on the Gigabyte MZK3-LM0 motherboard. It supports two AMD EPYC server processors for Socket SP5 and offers 24 DDR5 RMIMM slots per processor. The latter are arranged in a unique order of 6-2-4 on one side of the processor socket and 4-2-2-4 on the other side. In total, each of the Gigabyte R183-ZK0 and R283-ZK0 servers supports installation of up to 24 TB of RAM – 48 modules of 512 GB each.

As noted by the Serve the Home portal, which got acquainted with the new product at the Computex exhibition in early July, due to the limited area of ​​the board, the processor connectors on it are not located horizontally opposite each other, but diagonally. It looks unusual, but it works. The systems support up to 128-core, 256-thread AMD EPYC 9004 server processors and are also ready for select future next-generation EPYC processors.

The R283-ZK0 server is equipped with two Gigabit LAN network ports, eight bays for 2.5-inch NVMe PCIe 5.0 solid-state drives with hot-swap capability, four bays for 2.5-inch SATA/SAS-4 drives, two slots M.2 PCIe 3.0 x4 and PCIe 3.0 x2 standards, four FHHL PCIe 5.0 x16 connectors and two OCP 3.0 Gen5 x16. In addition, the new product supports the connection of two 2700-W power supplies with 80 Plus Titanium efficiency.

In turn, the more compact 1U Gigabyte R183-ZK0 system differs from the larger model in the presence of only four slots for hot-swappable PCIe 5.0 NVMe drives, one FHHL slot and can be equipped with power supplies up to 2000 W.

Gigabyte does not name the cost of the systems. However, such a server will not be cheap. For example, one 128-core AMD EPYC 9004 processor now costs about $10,000. Back in 2021, Samsung showed 512 GB DDR5 RAM modules for servers, but finding them on the market even now seems an unrealistic task. But, for example, a set of two DDR5 RDIMM RAM modules from Dell with a capacity of 256 GB each can currently be purchased for $6,335. Thus, the total cost of a server based on the Gigabyte MZK3-LM0 board will easily exceed one hundred thousand dollars.
