Chapter 1: Product introduction
ATX power connector. This 24/20-pin connector is for an ATX
power supply.
604-pin CPU sockets. A 604-pin surface mount, Zero Insertion
Force (ZIF) socket for the Intel
®
Xeon™ processor with 512KB L2
cache and a 533/400MHz system bus that allows up to 4.2GBps or
3.2GBps data transfer rates. These sockets support Intel Xeon
CPUs with Hyper-Threading Technology feature.
Intel E7505 MCH (Placer) . The E7505 Memory Controller Hub
(MCH) is the host bridge of the Placer chipset which is designed for
the next generation workstation or high-end desktop platforms. The
MCH supports the Intel
®
Xeon™ processor in dual-processor or uni-
processor mode at peak bandwidths of 4.2GBps (533MHz) or
3.2GBps (400MHz). The MCH works with the I/O Controller Hub
(ICH4) for the I/O subsystem, provides AGP 8x/4x interface
(compliant to AGP 3.0 specification), and supports dual-channel
DDR SDRAM interface for up to 8GB system memory.
8-pin 12V SSI power connector. This 8-pin connector is for an
ATX power supply.
DDR DIMM sockets. These four 184-pin DIMM sockets support up
to 8GB system memory using unbuffered/registered ECC/non-ECC
PC2100/1600 DDR DIMMs.
AGP Pro 8X slot. This Accelerated Graphics (AGP) Pro slot
supports 1.5V AGP 8X mode graphic cards to deliver up to 2.1GB/s
bandwidth.
Intel
®
P64H2 PCI-X hub. The P64H2 is PCI/PCI-X 64-bit Hub 2
that provides high-performance I/O capability including 16-bit Hub
Interface 2.0 connection to MCH, and two independent 64-bit PCI/
PCI-X interfaces.
IDE connectors. These dual-channel bus master IDE connectors
support up to four Ultra DMA/100/66, 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.
Floppy disk connector. This connector accommodates the
