Processors
The X5DP8-G2 supports single or dual Intel Xeon 604/603-pin processors of
up to 3.06 GHz with a 512K L2 cache at a 533/400 MHz FSB. Please refer
to the motherboard specifications pages on our web site ( http://
www.supermicro.com/Product_page/product-m.htm) for updates on sup-
ported processors.
Memory
The X5DP8-G2 has eight 184-pin DIMM slots that can support up to 16 GB of
registered ECC DDR-266 (PC2100) SDRAM. Module sizes of 128 MB, 256
MB, 512 MB, 1 GB and 2 GB may be used to populate the DIMM slots. (The
X5DP8-G2 was designed to support 2 GB DIMM modules for each memory
slot, but it has only been validated with 1GB memory modules.)
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 X5DP8-G2 provides two SCSI ports. A QLogic GEM318
controller is used for the SAF-TE compliant SCSI backpanel.
PCI Expansion Slots
The X5DP8-G2 has two 64-bit, 100 MHz PCI-X, four 64-bit, 66 MHz PCI and
one SXB (Super Extended Bus) slots. The SC822S chassis accommodates
up to six low profile add-on cards. Several jumpers on the motherboard are
used to change the speeds of these slots if needed (see Chapter 5).
ATI Graphics Controller
The X5DP8-G2 features an integrated ATI video controller based on the
Rage XL graphics chip. Rage XL utilizes 8 MB of memory and fully supports
sideband addressing. This onboard graphics package can provide a band-
width of up to 512 MB/sec over a 32-bit graphics memory bus.
Onboard Controllers/Ports
The X5DP8-G2 includes one floppy drive controller and two onboard IDE
controllers, which support up to four hard drives or ATAPI devices.
Backpanel I/O ports include one COM port, two USB ports, PS/2 mouse and
1-3
