Dual Socket 940 server board

The TYAN S2875ANRF is an ATX motherboard built for dual AMD Opteron processors in Socket 940. It uses the AMD 8151 northbridge and AMD 8111 southbridge with a Winbond W83627HF Super I/O ASIC. Four 184-pin DDR slots accept registered ECC DDR 400 memory up to 8 GB total.

Suited for legacy dual-CPU maintenance.

This board fits technicians repairing or extending existing Socket 940 platforms that rely on AGP 4X/8X graphics and 32-bit PCI expansion. Five PCI slots and one AGP slot provide the I/O mix those systems expect. Builders needing current-generation CPU sockets, PCI Express slots, or memory capacities beyond 8 GB should select a different platform.

Dual Socket 940 requirement

The defining specification is the pair of Socket 940 CPU sockets; the board only operates with two compatible AMD Opteron processors installed. If the target system uses any other socket type or a single-processor configuration, this motherboard will not fit.

Questions about this item

How can I confirm the AMD 8151 northbridge is active after installing dual Socket 940 Opteron processors?

The system should POST and show both CPUs detected in the BIOS setup; registered ECC DDR 400 memory must be reported at the correct speed and the onboard Realtek ALC655 audio should appear in the device list.

Which cables or add-in cards are not included with the S2875ANRF motherboard?

The board provides four SATA 1.5Gb/s ports and two ATA 133 connectors; SATA and PATA cables, an AGP graphics card and any PCI expansion cards must be purchased separately.

Should I choose 184-pin registered ECC DDR 400 modules or unbuffered memory for the four DIMM slots?

The chipset requires registered ECC DDR 400 (PC 3200) modules; unbuffered memory is not supported and the maximum capacity is 8 GB across the four slots.
