Intel® 5000P/5000V/5000Z Chipset Memory Controller Hub (MCH) Datasheet
Fully Buffered DIMM (FB-DIMM) Memory
Intel 5000V Chipset supports two channels of FB-DIMM DDR2 memory organized in
one branch. Each channel supports 4 DIMMs for a total of 8 DIMMs. The 8 DIMMs will
support a maximum of 16 GB physical memory. Since only one branch exists on the
Intel 5000V Chipset MCH, RAID 1 mirroring is not possible.
The Intel 5000V Chipset uses the same register programming model as the Intel 5000P
Chipset MCH with the exception that the FB-DIMM branch1 registers do not exist.
ESI Port
The Intel 5000V Chipset ESI port supports the same functionality as the Intel 5000P
Chipset ESI port. The resister models are the same.
PCI Express Ports
Intel 5000V Chipset supports two x4 ports of PCI Express. These two ports are
designated ports 2 and 3. These two x4 ports may be combined to form a single x8 PIC
Express port.
Ports 2 and 3 are normally used to supplement the bandwidth of the ESI port to the
Intel 631xESB/632xESB I/O Controller Hub South bridge. Ports 2 and 3 may also be
used to interface PCI Express connectors or down devices.
The register model for Intel 5000V Chipset ports 2 and 3 is the same as the Intel 5000P
Chipset with DMA Engine support. Unlike the Intel 5000P Chipset MCH, the Intel 5000V
Chipset does not have PCI Express ports 4, 5, 6, and 7.
System Management Bus Interfaces
The Intel® 5000V chipset MCH provides four fully functional System Management Bus
(SMBus) Revision 2.0 compliant target interfaces. These interfaces are used to support
platform level operations such as FB-DIMM memory Serial Presence Detect, PCI
Hot-Plug, and configuration of platform devices. Each of these interfaces have
dedicated uses as shown in
