Serverboard Features

CPU

• Single or dual AMD Opteron 200 series 64-bit processors in 940-pin microPGA

ZIF sockets

Memory

• Eight dual/single channel DIMM slots supporting up to 32 GB of registered ECC

DDR266 or up to 16 GB of registered ECC DDR400/333 SDRAM

Note: Memory capacities are halved for single CPU systems. Refer to Section 2-4 before installing.

Chipset

• AMD-8131/8111

Expansion Slots

H8DA8/H8DAE:

• Two (2) 64-bit, 133/100 MHz PCI-X (3.3V)

Note: These two slots share a single bus. When both slots are populated they will run at 100 MHz.

• Two (2) 64-bit, 66 MHz PCI-X (3.3V)

Note: PCI-X-#3 will support a Zero Channel RAID card

• Two (2) 32-bit, 33 MHz PCI (5V)

H8DAR-8/H8DAR-i:

• One (1) 64-bit, 100 MHz PCI-X (3.3V)

BIOS
