Single-socket Xeon platform

The TYAN S5652AGMNRE is a server motherboard built for Intel Xeon processors in the LGA 4677 socket. It uses the Intel C741 chipset and follows the SSI-CEB form factor. The board targets workloads that need high core counts and memory bandwidth in a single-processor configuration.

Eight-channel DDR5 and four PCIe 5.0 slots

Four DDR5 288-pin slots provide eight memory channels with ECC support, allowing up to 4TB of RAM when populated with 512GB modules. Four PCI Express 5.0 x16 slots accept up to two double-wide GPU accelerator cards. Six SATA 6.0Gb/s ports offer RAID 0, 1, 5 and 10. Rear I/O includes three USB 2.0 ports, two USB 3.2 ports, Intel I210 LAN at 10/100Mbps and Aspeed AST2600 graphics.

350W processor thermal design

The socket is rated for CPUs with a TDP up to 350W, so cooling must handle that heat load in sustained operation. Power delivery and VRM cooling are designed around this envelope. The Aspeed AST2600 BMC provides remote management without adding significant power draw. Acoustic output will depend on the chassis fans and CPU cooler selected for the 350W thermal target.

Questions about this item

Does the LGA 4677 socket on this board limit the CPU to a specific power envelope?

The board supports Intel Xeon processors with a TDP up to 350 W, so the socket and power delivery are rated for that ceiling.

What chassis clearance does the SSI-CEB form factor and the four PCIe 5.0 x16 slots require?

The SSI-CEB layout fits standard E-ATX server chassis; allow full-length, double-wide card space for the two GPU accelerators and ensure the rear I/O shield aligns with the board's port cluster.

What is the correct sequence for populating the eight DDR5 channels so the system posts on first boot?

Fill all eight slots — one DIMM per channel — using identical DDR5-4800 ECC modules; the common mistake is leaving a channel empty or mixing capacities, which prevents memory training from completing.
