ASUS P4P800S SE motherboard user guide
1-5
ATX power connector. This 20-pin connector connects to an ATX power
supply. The power supply must have at least 2A on the +5VSB lead and 15A
on the +12V lead.
ATX 12V connector. This power connector connects the 4-pin 12V plug from
the ATX 12V power supply.
CPU socket. A 478-pin surface mount, Zero Insertion Force (ZIF) socket for
the Intel
®
Pentium
®
4 Processor, with 800/533/400 MHz system bus that allows
6.4GB/s, 4.3GB/s, and 3.2GB/s data transfer rates, respectively.
North bridge controller. The Intel
®
848P Memory Controller Hub provides
the processor interface with 800/533/400 MHz frequency, system memory
interface at 400/333/266MHz operation, and 1.5V AGP interface that supports
AGP 3.0 specification including 8X Fast Write protocol. The Intel
®
848P
Memory Controller Hub interconnects to the SouthBridge ICH5 via the Intel
®
proprietary Hub Interface.
Super I/O controller. This Winbond Low Pin Count (LPC) interface provides
the commonly used Super I/O functionality. The chipset supports a high-
performance floppy disk controller for a 360K/720K/1.44M/2.88M floppy disk
drive, a multi-mode parallel port, two standard compatible UARTs, and a Flash
ROM interface.
DDR DIMM sockets. These two 184-pin DIMM sockets support up to 2GB
system memory using unbuffered non-ECC PC3200/2700/2100 DDR DIMMs.
Floppy disk connector. This connector accommodates the provided ribbon
cable for the floppy disk drive. One side of the connector is slotted to prevent
incorrect insertion of the floppy disk cable.
IDE connectors. These dual-channel bus master IDE connectors support
Ultra DMA100/66, PIO Modes 3 & 4 IDE devices. Both the primary (blue) and
secondary (black) connectors are slotted to prevent incorrect insertion of the
IDE ribbon cable.
SATA connectors. These connectors support Serial ATA HDDs and allow
up to 150MB/s data transfer rate using thin 4-conductor SATA cables.
Flash ROM. This 3Mb firmware contains the programmable BIOS program.
South bridge controller. The fifth-generation Intel I/O Controller Hub (ICH5)
is a subsystem that integrates various I/O functions including 2-channel
ATA100 bus master IDE controller, SATA controller, up to eight USB 2.0/1.1
ports, I/O APIC, SMBus controller, LPC interface, AC’97 2.3 interface, and PCI
2.3 interface. The ICH5 also contains the necessary arbitration and buffering
for efficient utilization of these interfaces.
Standby power LED. This LED lights up if there is a standby power on the
motherboard. This LED acts as a reminder to turn off the system power
before plugging or unplugging devices.
Audio CODEC. The ADI AD1888 is an AC’97 CODEC that allows
6-channel audio playback.
