Introduction
The MCH provides four channels of Fully Buffered DIMM (FB-DIMM) memory. Each
channel can support up to 4 Dual Ranked FB-DIMM DDR2 DIMMs. FB-DIMM memory
channels are organized in to two branches for support of RAID 1 (mirroring). The MCH
can support up to 16 DIMMs or a maximum memory size of 64 GB physical memory in
non-mirrored mode and 32 GB physical memory in mirrored configuration. The read
bandwidth for each FB-DIMM channel is 4.25 GB/s for DDR2 533 FB-DIMM memory
which gives a total read bandwidth of 17GB/s for four FB-DIMM channels. Thus this
provides 8.5 GB/s of write memory bandwith for four FB-DIMM channels. The read
bandwidth for each FB-DIMM channel is 5.325 GB/s for DDR2 667FB-DIMM memory
which gives a total read bandwidth of 21.3 GB/s for four FB-DIMM channels. Thus this
provides 10.7GB/s of write memory bandwith for four FB-DIMM channels. The total
bandwidth is based on read bandwidth therefore the total bandwidth is 17 GB/s for 533
and 21.3 GB/s for 667.
The Intel 631xESB/632xESB I/O Controller Hub integrates an Ultra ATA 100 controller,
six Serial ATA host controller ports, one EHCI host controller, and four UHCI host
controllers supporting eight external USB 2.0 ports, LPC interface controller, flash BIOS
interface controller, PCI interface controller, Azalia / AC’97 digital controller, integrated
LAN controller, an ASF controller and a ESI for communication with the MCH. The
Intel 631xESB/632xESB I/O Controller Hub component provides the data buffering and
interface arbitration required to ensure that system interfaces operate efficiently and
provide the bandwidth necessary to enable the system to obtain peak performance.
The Intel 631xESB/632xESB I/O Controller Hub elevates Serial ATA storage
performance to the next level with Intel^® RAID.
The ACPI compliant Intel 631xESB/632xESB I/O Controller Hub platform can support
the Full-on, Stop Grant, Suspend to RAM, Suspend to Disk, and Soft-Off power
management states. Through the use of the integrated LAN functions, the Intel
631xESB/632xESB I/O Controller Hub also supports Alert Standard Format for remote
management.
