The TURIN2D48G-2L+ from ASRock Rack is a major new server motherboard designed to meet the most demanding needs of high-performance computing.
Supporting two AMD EPYC 9005/9004 series processors, including the top-of-the-line 192-core EPYC 9965, this motherboard is designed for maximum power and memory capacity.
With 48 DIMM slots (24 per CPU socket), it can support up to 96 GB per RDIMM and up to 512 GB per RDIMM-3DS module (for a total of 24.6 TB), providing significant memory scalability. The board also supports DDR5 memory with frequencies up to 5200 MHz for single DIMMs per channel (1DPC), or 4400 MHz when using dual DIMMs per channel (2DPC).
For the most demanding workloads
The layout of the TURIN2D48G has been specifically designed to meet these enormous memory and processing requirements. Measuring 18″ x 16.9″, the board can support CPUs with a TDP of up to 500W, adequately managing even the most power-hungry processors. To accommodate the 48 DIMM slots, the CPU sockets have been offset.
In addition to offering more memory capacity than many competing platforms, the motherboard also offers impressive PCIe and storage options. It supports 12 MCIO slots (PCIe 5.0/CXL 2.0 x8), along with up to 34 SATA 6Gb/s connections, and two M.2 slots also provide further storage options, each supporting PCIe 3.0 x4 or SATA 6Gb/s drives.
Networking is provided by two RJ45 1GbE ports, powered by Intel’s i350 controller, and remote management is available via integrated IPMI with a dedicated LAN management port.
The TURIN2D48G is designed to excel in environments where massive memory and high core counts are crucial. Support for CXL 2.0 and PCIe 5.0 promises fast communication between processors, memory and peripherals, while integrated cooling options, with support for powerful CPUs, make it suitable for the most demanding workloads such as AI training and large-scale data analysis.

ServeTheHome I got my first look at the motherboard at AMD’s AI event following the launch of the EPYC 9005 Turin and noted, “The great thing about this motherboard is that besides supporting a large core count and DIMM count, it also offers something that Intel doesn’t. The Intel Xeon 6900P also has 12-channel memory, but only supports 1 DIMM per channel. As a result, AMD’s 12-channel 2DPC offering does more than just max out the raw core count for AMD EPYC Turin platforms versus Intel Xeon platforms. It’s also cool to see such a large motherboard!”
