Processors
The X5DPR-8G2+ supports single or dual Intel 604/603-pin Xeon processors of up
to 3.20 GHz at a 533/400 MHz FSB. Please refer to the support section of our
web site for a complete listing of supported processors (http://
www.supermicro.com/TechSupport.htm).
Memory
The X5DPR-8G2+ has 6 184-pin, DIMM slots that can support up to 12 GB of
low-profile, registered ECC DDR-266/200 (PC2100/1600) SDRAM. Module
sizes of 128 MB, 256 MB, 512 MB, 1 GB and 2 GB may be used to populate
the DIMM slots. (This serverboard has has been designed to support 2GB
DIMM modules for each memory slot, but it has only been validated with 1GB
memory modules. Memory modules of different sizes and speeds should not be
mixed.)
Onboard SCSI
Onboard SCSI is provided with an Adaptec AIC-7902 SCSI controller chip,
which supports dual channel, Ultra320 SCSI at a burst throughput rate of
320 MB/sec. The X5DPR-8G2+ provides two SCSI ports. A QLogic GEM318
controller is used for the SAF-TE compliant SCSI backpanel.
PCI Expansion Slots
The X5DPR-8G2+ has one 64-bit, 133 MHz PCI-X slot and one slim 64-bit, 66
MHz PCI slot. A "butterfly" riser card is included with the server. This riser
card fits into the 133 MHz PCI-X slot and was designed specially for the SC812S-
400 chassis to support the use of one standard PCI card and one low profile (half-
height, half-length) PCI card. Several jumpers on the motherboard are used to
change the speeds of these slots if needed (see Chapter 5).
ATI Graphics Controller
The X5DPR-8G2+ features an integrated ATI video controller based on the
Rage XL graphics chip.
AGP texturing. This onboard graphics package can provide a bandwidth of
up to 512 MB/sec over a 32-bit graphics memory bus.
Rage XL fully supports sideband addressing and
