Chapter 1: Introduction
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. Rage XL fully supports sideband addressing and AGP texturing. This onboard graphics package can provide a bandwidth of up to 512 MB/sec over a 32-bit graphics memory bus.
