channels of registered fully-buffered DIMM (FBD) DDR2 533/667 MHz memory (stacked or unstacked). Peak theoretical memory data bandwidth using FBD 533/667 MHz technology is 6.4 and 8 GB/s, respectively.
When all four memory channels are populated and operating, they function in lock-step mode. The maximum supported FBD DDR2 533/667 MHz memory configuration is 64 GB.
The Intel

5000 MCH memory interface provides several reliability, availability, serviceability,
usability, and manageability (RASUM) features, including:
Memory mirroring allows two copies of all data in the memory subsystem (one on each
channel) to be maintained.
Memory sparing allows one DIMM per channel to be held in reserve and brought on-line
if another FBDIMM in the channel becomes defective.
Hardware periodic memory scrubbing, including demand scrub support. Retry on uncorrectable memory errors. Intel

5000 MCH complies with the PCI
Express Interface Specification, Revision 1.0a. The Intel

5000 MCH provides three x8 PCI Express* interfaces, each with a maximum theoretical bandwidth of 4.2 GB/s. Each of these x8 PCI Express interfaces may alternatively be configured as two independent x4 PCI Express interfaces. A PCI Express interface/port is defined as a collection of lanes. Each lane (x1) consists of two striped differential pairs in each direction (transmit and receive). The raw bit-rate on the data pins of 2.5 Gb/s, results in a real bandwidth of 250 MB/s per pair, given the 8/10 bit encoding used to transmit data across this interface.

2.1.1.3.1 PCI Express* Training
To establish a connection between PCI Express* endpoints, the endpoints participate in a sequence of steps called training. This sequence establishes the operational width of the link and adjusts skews of the various lanes within a link so that the data sample points can correctly take a data sample from the link.
In the case of a x8 port, the x4 link-pairs first attempt to train independently, and will collapse to a single link at the x8 width upon detection of a single device returning link ID information upstream. Once the number of links has been established, they negotiate to train at the highest common width, and step down in its supported link widths to succeed in training. The result may be that the link has trained as a x1 link.
Although the bandwidth of this link size is substantially lower than a x8 link or a x4 link, it allows communication between the two devices. Software can then interrogate the device at the other end of the link to determine why it failed to train at a higher width. This would not be possible without support for the x1 link width.
Width negotiation is done only during training or retraining, not during recovery.
2.1.1.3.2 PCI Express* Retry
The PCI Express* interface incorporates a link-level retry mechanism. The hardware detects a corrupted transmission packet and performs a retry of that packet and all following packets. Although this causes a temporary interruption in the delivery of packets, the retry helps to maintain the link integrity.
2.1.1.3.3 PCI Express* Link Recovery
If excessive errors occur, the hardware can determine that the quality of the connection is in question and the end points can enter a quick training sequence, known as recovery. The width of the connection will not be renegotiated, but the adjustment of skew between lanes of the link might occur. This occurs without any software intervention, but the software might be notified.
2.1.1.3.4 PCI Express* Data Protection
The PCI Express* high-speed serial interface uses traditional CRC protection. The data packets use a 32-bit CRC protection scheme, the same CRC-32 used by Ethernet. The smaller link packets use a 16-bit CRC scheme. Since packets utilize 8B/10B encoding, and not all encodings are used; this provides further data protection, as illegal codes can be detected. If errors are detected on the reception of data packets due to various transients, these data packets can be retransmitted. Hardware logic supports this link-level retry without software intervention.

2.1.1.3.5 PCI Express* Retrain
If the hardware is unable to perform a successful recovery, then the link automatically reverts to the polling state and initiates a full retraining sequence. This is a drastic event with an implicit reset to the downstream device and all subordinate devices, and is logged by the Intel
®
5000 MCH as a "Link Down" error. If escalation of this event is enabled, software is notified of the link DL_DOWN condition. If software is involved, then data is probably lost, and processes need to be restarted. This is preferred over the taking down the system or going offline for an extended time.

2.1.2.8 Compatibility Modules (DMA Controller, Timer/Counters, Interrupt
Controller)
The DMA controller incorporates the logic of two 82C37 DMA controllers, with seven independently programmable channels. Channels 0–3 are hardwired to 8-bit, count-by-byte transfers, and channels 5 through 7 are hardwired to 16-bit, count-by-word transfers. Any two of the seven DMA channels can be programmed to support fast Type-F transfers.

Single, demand, verify, and increment modes are supported on the LPC interface. Channels 0–3 are 8 bit channels. Channels 5 through 7 are 16-bit channels. Channel 4 is reserved as a generic bus master request.
The timer / counter block contains three counters that are equivalent in function to those found in one 82C54 programmable interval timer. These three counters are combined to provide the system timer function, and speaker tone. The 14.31818-MHz oscillator input provides the clock source for these three counters.
The Intel
®
631xESB / 632xESB I/O Controller Hub provides an ISA-compatible programmable interrupt controller (PIC) that incorporates the functionality of two 82C59 interrupt controllers. The two interrupt controllers are cascaded so that 14 external and two internal interrupts are possible. In addition, the I/O Controller Hub supports a serial interrupt scheme. All of the registers in these modules can be read and restored. This is required to save and restore the system state after power has been removed and restored to the platform.

2.3 Memory Sub-system

The Intel® boards that use the Intel® 5000 MCH support several fully-buffered (FBD) memory modes of operation.
Single-channel mode (single DIMM mode) Single-branch / dual-channel mode Dual-branch / dual-channel mode (four channels) Memory sparing mode Memory mirroring mode
Note: Memory sparing and mirroring features are currently disabled and will be made available after production launch.
The Intel® 5000 MCH provides an integrated memory controller for direct connection to four channels routed to eight connectors supporting registered DDR2-533 and DDR2-667 FBDIMM memory (stacked or unstacked). Peak theoretical memory data bandwidth is 6.4 GB/s with DDR2-533 and 8.0 GB/s with DDR2-667.
A pair of channels is a branch. Branch 0 consists of channel A and channel B, Branch 1 consists of channel C and channel D. A DIMM can have two ranks; a channel supports a maximum of eight ranks.

Functional Architecture Intel® 5000 Series Chipsets Server Board Family Datasheet
In non-mirrored operation, the two DDR2 channels within a branch operate in lock-step and the branches operate independently. When memory mirroring is configured, the channels operate in lock-step under normal conditions, but independently under failure and recovery conditions.
The Intel
®
5000 MCH supports a burst length of four in either single-channel mode or dual­channel mode. In dual-channel mode this results in eight 64-bit chunks (64-byte cache line) from a single read or write. In single-channel mode, two reads or writes are required to access a cache line of data.
Memory between 32 GB, and 32 GB minus 512 MB, is not accessible for use by the operating system and may be lost to the user. This area is reserved for the BIOS, APIC configuration space, PCI adapter interface, and virtual video memory space. This means that if 32 GB of memory is installed, 31.5 GB of this memory is usable. The chipset should allow the remapping of unused memory above the 32 GB address, but this memory may not be accessible to an operating system that has a 32 GB memory limit.
To boot the system, the system BIOS uses a dedicated I needed to program the Intel
®
5000 MCH memory registers.

C bus to retrieve DIMM information
2.3.1 Fully-buffered DIMM (FBDIMM)
The fully-buffered DIMM (FBDIMM) memory interface provides a high-bandwidth, large-capacity channel solution that has a narrow host interface. FBDIMMs use commodity DRAMs isolated from the channel behind an advanced memory buffer (AMB) on the DIMM that allows a greater number of devices per channel without loading the interconnect and affecting performance. Memory capacity remains at a maximum of 36 devices per DIMM and total memory capacity scales with DRAM bit density.
FBD is a differential pair, point-to-point interface. The interface consists primarily of 10 southbound differential pairs (outputs from the Intel northbound differential pairs (inputs to the Intel
®
5000 MCH to the DIMMs) and 14
®
5000 MCH from the DIMMs). The Intel® 5000 MCH is connected only to the closest FBDIMM in the channel and communicates with the AMB on that FBDIMM. The AMB on the closest FBDIMM communicates with the AMB on the next FBDIMM in the channel, and so on. This point-to-point solution eliminates problems associated with a “stub-bus” architecture and allows memory capacity to increase without loading the channel. The figure below shows the FBD topology.

2.3.2 Supported Memory
The Intel® 5000 MCH supports single-channel DIMM operation in which only one FBDIMM is installed in DIMM socket A1. Population in other DIMM banks is not supported for single­channel operation.
The server and workstation boards provide the maximum memory capacities outlined in Table 1, based on the number of DIMM slots provided and maximum supported memory loads by the chipset. The minimum memory supported with the system running in single-channel memory mode is 512 MB, using a single DIMM in the DIMM A1 socket.
Note: All Intel memory qualification is done by testing with complete memory banks of identical memory modules in all DIMM sockets. Memory qualification does not include testing of single­channel memory mode, mixed DIMM type and/or vendors.
Supported DIMM capacities are 512 MB, 1 GB, 2 GB, and 4 GB.

DIMMs on channel A are paired with DIMMs on channel B to configure 4-way interleaving. Each DIMM pair is referred to as a bank. The bank can be further divided into two rows, based on single-sided or double-sided DIMMs. If both DIMMs in a bank are single-sided, only one row is said to be present. For double-sided DIMMs, both rows are said to be present.
The server and workstation boards have eight DIMM slots, or four DIMM channels. Both DIMMs in a channel should be identical (same manufacturer, CAS latency, number of rows, columns and devices, timing parameters, etc.). Although DIMMs within a channel must be identical, the BIOS supports various DIMM sizes and configurations, allowing the channels of memory to be different. Memory sizing and configuration is guaranteed only for qualified DIMMs approved by Intel.
Note: Some boards vary in memory capacity. See the server or workstation Technical Product Specification that applies to your product for more information.
