Intel® SHG2 DP Server Board Technical Product Specification Introduction
Revision 1.0 Intel Order Number C11343-001 3
Server management and monitoring hardware are also included. These features, and the
others listed below, make this one of the most highly integrated server boards in this class.
SHG2 supports two interleaved memory channels at 100 MHz, each utilizing the rising edge
and falling edge of the clock cycle for 200MT/s per channel (also known as “double pumped”)
for a combined throughput of 400 MT/s. The subsystem was originally intended for PC1600
DDR memory modules (DDR200), however up to 6 DDR200 of DDR266 registered memory
modules (PC1600 or PC2100 DIMMs) inserted as pairs may be used. Each DIMM may provide
up to 2 GB of memory capacity, providing up to 12 GB of system memory.
Note: Although the use of DDR266 modules is supported for upward compatibility, the channel
throughput is fixed at 400 MT/s, and the use of higher speed DIMMs will not provide additional
bandwidth. Mixed memory is not recommended, all DIMM sites should be populated with the
same speed and, when possible, same manufacturer.
The SHG2 server board provides the following features:
• Dual Intel Xeon processor support.
- Two processor sockets for installation of one to two identical Intel Xeon processors.
- Embedded VRMs to support two Xeon processors.
•
ServerWorks Grand Champion LE chipset.
- Champion Memory and I/O Controller-Low End (CMIC-LE).
- Champion South Bridge (CSB5).
- Champion I/O Bridge (CIOBX2).
•
Support for 6 DDR registered ECC Synchronous Dynamic RAM (SDRAM) DIMMs.
- Error Correcting Code (ECC) single-bit correction, and multiple-bit error detection
and memory scrubbing.
- Supports Chipkill* technology
• 32-bit, 33-MHz 5V keyed PCI segment with three expansion connectors and two
embedded devices with external connectors.
- One PCI NIC—Intel 82550PM Fast Ethernet Controller with a dedicated RJ-45
connector at the rear I/O panel
- 3D/2D Graphics Accelerator —ATI* RAGE XL Video Controller with DB15 VGA
connector at the rear I/O panel
• 64-bit, 100-MHz, 3.3V PCI-X segment with two expansion connectors and one
embedded device.
- One PCI-X network interface controller—Intel 82544GC Gigabit Ethernet Controller
with a dedicated RJ-45 connector at the rear I/O panel
•
64-bit, 133-MHz, 3.3V PCI-X segment with one expansion connector and one
embedded device.
- Dual Channel Ultra* 160 SCSI Controller—Adaptec* 7899 SCSI Controller.
Note: When the 7899 SCSI Controller is enabled, this bus segment will run at 66MHz in
PCI mode. When disabled, the segment is capable of 133MHz PCI-X mode.
•
X-bus segment with one embedded device.
- 8-Mbit flash device for system BIOS.
•
LPC bus segment with two embedded devices.
