PROCESSOR
Dual Intel® Xeon™ processors 2.0GHz to 2.8GHz
HYPER-THREADING TECHNOLOGY
Intel's Hyper-Threading technology makes a single Intel® Xeon™ processor appear as two logical processors. The operating system and application must be optimized for Hyper-Threading. The CDX's two physical Intel® Xeon™ processors will function as four logical processors in applications optimized for Hyper-Threading.
CHIPSET
The Intel® E7501 chipset provides support for dual Intel® Xeon™ processors, a 400/533 system bus, and PC1600 or PC2100 DDR memory with ECC.
SYSTEM BUS
The Intel® E7501 chipset supports a system bus speed of 400/533MHz.
BUS SPEED
ISA 16-bit/8MHz
PCI 32-bit/33MHz or 64-bit/66MHz
PCI-X 64-bit/66Mhz, 64-bit/100MHz or 64bit/133MHz
Hub Link 2.0 1GB/s
System/FSB 400/533MHz
BIOS (FLASH)
AMIBIOS8® has built-in advanced CMOS setup for system parameters, peripheral management for configuring on-board peripherals, PCI-to-PCI bridge support and PCI interrupt steering. Supports flash devices for BIOS upgrading via floppy interface. Also provides integrated support for USB mass storage devices such as USB, CD-ROM, CD-RW, etc. Custom BIOSs are available upon request.
CACHE MEMORY
Each Intel® Xeon™ processor supports a 512K integrated on-die Advanced Transfer Cache (L2). The cache is an 8-way set associative cache running at full processor core frequency. The Execution Trace Cache (L1) is a 12K data cache that stores thousands of decoded micro-operations. The purpose of this L1 cache is to remove decoder latency from the processor's main execution path, resulting in increased processor performance.
DDR200/266 MEMORY
The DDR memory interface on the CDX consists of two channels, each terminating at a pair of DIMM module sockets. The CDX supports auto detection of up to 8GB of memory. The system BIOS automatically detects memory type, size and speed. The four memory sockets on the SBC must be populated in pairs, beginning with the sockets in Bank 1, and must contain ECC registered PC1600 or PC2100 DIMMS. All DIMMS must be the same speed (PC1600 or PC2100). The modules within a pair must be the same size; however, if two pairs are used, each pair can contain a different size module. The maximum memory capacity of the CDX is 8GB and the minimum interface bandwidth is 1600MB/s.
ERROR CHECKING AND CORRECTION
The memory interface supports ECC modes via BIOS setting for multiple-bit error detection and correction of all errors confined to a single nibble.
PCI-X BUS INTERFACE
The PCI-X bus interface supports a 64-bit PCI-X backplane interface running at either a 66MHz, 100MHz or 133MHz bus speed.
PCI BUS INTERFACE
The PCI bus interface supports either a 32-bit/33MHz or a 64-bit/66MHz PCI backplane interface.
ISA BUS
The CDX provides a 16-bit ISA bus interface to the backplane for legacy ISA slots.
SYSTEM HARDWARE MONITOR
The Winbond W83783S chip supports hardware monitoring. The functions monitored are voltage, fan speed and temperature. The CDX hardware monitor software allows the user to program the monitor limits to provide trigger points for the application software. This allows the application program to monitor these trigger points in order to send system alert messages or perform corrective actions.
FLOPPY DRIVE INTERFACE
Supports up to two floppy disk drives in combinations of 360K to 2.88MB.
ULTRA XGA VIDEO INTERFACE
The ATI M6-C16H video controller enables 2D/3D video acceleration and provides 16MB of integrated video DDR memory. The video controller supports pixel resolutions up to 1600 x 1200. Software drivers are available for most popular operating systems.
SERIAL INTERFACE
The Super I/O controller supports two full-function serial ports with independently programmable baud rates. The controller has two high-speed, NS16C550 compatible, UARTs with Send/Receive 16-Byte FIFOs. The IRQ for each serial port has BIOS selectable addressing.
ENHANCED BI-DIRECTIONAL PARALLEL INTERFACE
The parallel port interface is compatible with IBM PC/XT®, PC/AT®, PS/2T, Enhanced Parallel Port (EPP1.7, EPP1.9) and Extended Capabilities Port (ECP) modes of operation. Both the EPP and ECP modes are IEEE 1284 compliant. The parallel port has BIOS selectable addressing.
USB INTERFACES (DUAL)
The CDX supports two USB 1.1 ports for serial transfers at 12 or 1.5Mbit/sec. The Universal Serial Bus (USB) is an interface allowing for connectivity to many standard PC peripherals via an external port.
DUAL ETHERNET INTERFACES- 10/100/1000BASE-T
The CDX has an internal PCI-X bus that connects to Intel's 82546EB Ethernet Controller chip. This board design feature provides high-speed dual Gigabit Ethernet on LAN ports 1 and 2. The CDX also supports existing 10Mb or 100Mb per second Ethernet networks over the same internal PCI-X bus. RJ-45 connectors located on the I/O bracket provide the mechanical interface to the Ethernet networks.
