Refer to Section 2.1.1 on page 45 for information on the total amount of addressable memory. Minimum total system memory: 128 MB ECC DIMMs and non-ECC DIMMs Serial Presence Detect DDR2 667 and 533 MHz SDRAM DIMMs NOTES · · Remove the PCI Express x16 video card before installing or upgrading memory to avoid interference with the memory retention mechanism. To be fully compliant with all applicable DDR SDRAM memory specifications, the board should be populated with DIMMs that support the Serial Presence Detect (SPD) data structure. This allows the BIOS to read the SPD data and program the chipset to accurately configure memory settings for optimum performance. If non-SPD memory is installed, the BIOS will attempt to correctly configure the memory settings, but performance and reliability may be impacted or the DIMMs may not function under the determined frequency. Table 4 lists the supported DIMM configurations. Table 4. DIMM Capacity 128 MB 256 MB 256 MB 512 MB 512 MB 512 MB 1024 MB 1024 MB 2048 MB Notes: 1. 2.

This mode offers the highest throughput for real world applications. Dual channel mode is enabled when the installed memory capacities of both DIMM channels are equal. Technology and device width can vary from one channel to the other but the installed memory capacity for each channel must be equal. If different speed DIMMs are used between channels, the slowest memory timing will be used. Single channel (Asymmetric) mode. This mode is equivalent to single channel bandwidth operation for real world applications. This mode is used when only a single DIMM is installed or the memory capacities are unequal. Technology and device width can vary from one channel to the other. If different speed DIMMs are used between channels, the slowest memory timing will be used.

The ICH7-R is a centralized controller for the board's I/O paths. For information about The Intel 955X chipset Resources used by the chipset Refer to http://developer.intel.com/ Chapter 2 1.5.1 USB The board supports up to eight USB 2.0 ports, supports UHCI and EHCI, and uses UHCI- and EHCI-compatible drivers. The ICH7-R provides the USB controller for all ports. The port arrangement is as follows: · · Four ports are implemented with dual stacked back panel connectors adjacent to the audio connectors Four ports are routed to two separate front panel USB connectors NOTES Computer systems that have an unshielded cable attached to a USB port may not meet FCC Class B requirements, even if no device is attached to the cable. Use shielded cable that meets the requirements for full-speed devices. For information about The location of the USB connectors on the back panel The location of the front panel USB connectors Refer to Figure 18, page 55 Figure 19, page 56 1.5.2 · · IDE Support One parallel ATA IDE connector that supports two devices Four serial ATA IDE connectors that support one device per connector The board provides five IDE interface connectors: 1.5.2.1 Parallel ATE IDE Interface The ICH7-R's Parallel ATA IDE controller has one bus-mastering Parallel ATA IDE interface. The Parallel ATA IDE interface supports the following modes: · · Programmed I/O (PIO): processor controls data transfer. 8237-style DMA: DMA offloads the processor, supporting transfer rates of up to 16 MB/sec. 21 Intel Desktop Board D955XBK Technical Product Specification · · · Ultra DMA: DMA protocol on IDE bus supporting host and target throttling and transfer rates of up to 33 MB/sec. ATA-66: DMA protocol on IDE bus supporting host and target throttling and transfer rates of up to 66 MB/sec. ATA-66 protocol is similar to Ultra DMA and is device driver compatible. ATA-100: DMA protocol on IDE bus allows host and target throttling. The ICH7-R's ATA-100 logic can achieve read transfer rates up to 100 MB/sec and write transfer rates up to 88 MB/sec. NOTE ATA-66 and ATA-100 are faster timings and require a specialized cable to reduce reflections, noise, and inductive coupling. The Parallel ATA IDE interface also supports ATAPI devices (such as CD-ROM drives) and ATA devices using the transfer modes. The BIOS supports Logical Block Addressing (LBA) and Extended Cylinder Head Sector (ECHS) translation modes. The drive reports the transfer rate and translation mode to the BIOS. For information about The location of the Parallel ATA IDE connector Refer to Figure 19, page 56 1.5.2.2 Serial ATA Interfaces The ICH7-R's Serial ATA controller offers four independent Serial ATA ports with a theoretical maximum transfer rate of 3 Gbits/sec per port. One device can be installed on each port for a maximum of four Serial ATA devices. A point-to-point interface is used for host to device connections, unlike Parallel ATA IDE which supports a master/slave configuration and two devices per channel. For compatibility, the underlying Serial ATA functionality is transparent to the operating system. The Serial ATA controller can operate in both legacy and native modes. In legacy mode, standard IDE I/O and IRQ resources are assigned (IRQ 14 and 15). In Native mode, standard PCI Conventional bus resource steering is used. Native mode is the preferred mode for configurations using the Windows* XP and Windows 2000 operating systems. NOTE Many Serial ATA drives use new low-voltage power connectors and require adaptors or power supplies equipped with low-voltage power connectors. For more information, see: http://www.serialata.org/ For information about The location of the Serial ATA IDE connectors on the D955XBK board Refer to Figure 19, page 56 22 Product Description 1.5.2.3 · Serial ATA RAID RAID 0 - data striping. Multiple physical drives can be teamed together to create one logical drive. As data is written or retrieved from the logical drive, both drives operate in parallel, thus increasing the throughput. The ICH7-R allows for more than two drives to be used in a RAID 0 configuration. RAID 1 - data mirroring. Multiple physical drives maintain duplicate sets of all data on separate disk drives. Level 1 provides the highest data reliability because two complete copies of all information are maintained. The ICH7-R allows for two or four drives to be used in a RAID 1 configuration. RAID 0+1 (or RAID 10) - data striping and mirroring. RAID 0+1 combines multiple mirrored drives (RAID 1) with data striping (RAID 0) into a single array. This provides the highest performance with data protection. Data is striped across all mirrored sets. RAID 0+1 utilizes several drives to stripe data (increased performance) and then makes a copy of the striped drives to provide redundancy. The mirrored disks eliminate the overhead and delay of parity. RAID 5 - distributed parity. RAID Level 5 stripes data at a block level across several drives and distributes parity among the drives; no single disk is devoted to parity. Because parity data is distributed on each drive, read performance tends to be lower than other RAID types. RAID 5 requires the use of three or four drives. The ICH7-R supports the following RAID (Redundant Array of Independent Drives) levels: · · · 1.5.2.4 SCSI Hard Drive Activity LED Connector (Optional) The SCSI hard drive activity LED connector is a 1 x 2-pin connector that allows an add-in hard drive controller to use the same LED as the onboard IDE controller. For proper operation, this connector should be wired to the LED output of the add-in hard drive controller.
