  • Extended ATX 12.0" x 13.1" fits standard server chassis

Dual Socket-940 server board

The Supermicro H8DAR-8 is an extended-ATX motherboard built around the AMD 8131 and 8111 chipset. It accepts two processors in Socket PGA-940 packages and provides eight DDR SDRAM slots for up to 32 GB of memory. Onboard SCSI with RAID, video and LAN are integrated. The board is supplied new without accessories.

Replaces single-socket or non-RAID platforms

Moving to this board makes sense when a workload needs two CPUs and hardware SCSI RAID on the same PCB. The dual-socket layout and integrated RAID controller remove the need for a separate storage card. Builders staying with a single processor or using only software RAID will not benefit from the extra socket and controller.

Check chassis, power and memory before ordering

Verify that the case accepts a 12.0 by 13.1 inch extended-ATX footprint and that the power infrastructure can deliver 208 to 230 V AC. Confirm that DDR SDRAM modules are available for the eight slots and that the intended Socket PGA-940 processors are on hand. The board includes only two USB 2.0 ports, so additional I/O may require add-in cards.

Questions about this item

Will the 12.0" by 13.1" extended-ATX board fit my chassis?

The board measures 12.0 inches wide by 13.1 inches deep and uses the extended-ATX form factor, so the chassis must support that exact size and mounting pattern.

Which CPU coolers clear the dual Socket PGA-940 layout?

Each socket follows the PGA-940 specification; coolers must be rated for that socket and low enough to avoid interfering with adjacent memory slots or the AMD 8131/8111 chipset heatsinks.

What is the maximum DDR SDRAM capacity I can install later?

Eight memory slots support a total of 32 GB of DDR SDRAM, so the ceiling is fixed at that amount regardless of module density.
