Processors
The P4DPR-6GM+ supports single or dual Intel Xeon 512K L2 cache processors
of up to 3 GHz at a 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 P4DPR-6GM+ has 4 184-pin, 25 degree DIMM slots that can support up to
8 GB of registered ECC DDR-200 DDR SDRAM. Module sizes of 128 MB, 256
MB, 512 MB, 1 GB and 2 GB may be used to populate the DIMM slots. (DDR-
266 is also supported, but only at a speed of 200 MHz.)
Onboard SCSI
Onboard SCSI is provided with an Adaptec AIC-7899W SCSI controller chip,
which supports dual channel, Ultra160 SCSI at a burst throughput rate of
160 MB/sec. The P4DPR-6GM+ provides two SCSI ports. A QLogic GEM318
controller is used for the SAF-TE compliant SCSI backpanel.
PCI Expansion Slots
The P4DPR-6GM+ has one 64-bit, 133 MHz PCI-X slot and one 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
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 P4DPR-6GM+ features an integrated ATI video controller based on the Rage
XL graphics chip.
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 AGP
