Processors
The P4SBR/P4SBE supports single 478-pin Pentium 4 microPGA processors
at 2.60 GHz at a front side (system) bus speed of 400 MHz. 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 P4SBR/P4SBE has three (3) 168-pin DIMM sockets that can support up
to 3 GB of unbuffered PC133 and PC100 low-profile SDRAM modules. Mod-
ule sizes of 128 MB, 256 MB, 512 MB and 1 GB may be used to populate the
DIMM slots. The DIMM slots on the P4SBR (5012H) are situated at a 25
degree angle to create a low profile and to promote efficient airflow through
the chassis.
Onboard SCSI (5012B-6 only)
Onboard SCSI is provided with an Adaptec AIC-7899 SCSI controller chip,
which supports dual channel, Ultra160 SCSI at a burst throughput rate of
160 MB/sec for each channel. The P4SBR provides two SCSI ports: one
internal 68-pin LVD Ultra160 connector (on Channel A) and one external/
internal (shared) 68-pin Ultra160 SCSI connector (channel B).
PCI Expansion Slots
The P4SBR/P4SBE has five 32-bit, 33 MHz PCI slots available. One riser
card is included with the system for use with 32-bit PCI cards.
Network Interface Controllers (NIC)
The P4SBR/P4SBE supports two Network Interface controllers (NIC) based
on Intel's 82550 10/100 Mbps fast Ethernet controller chip.
Onboard Controllers/Ports
An onboard IDE controller supports one floppy drive and up to four UDMA/
100 hard drives or ATAPI devices. Onboard I/O ports include one COM port,
one parallel port, two USB ports, PS/2 mouse and keyboard ports, a video
(graphics) port and two LAN (NIC) ports, which back each other up in case
one port loses its connection.
