Intel SHG2 Product Guide - Page 12

Processor The Intel® Server Board SHG2 supports one or two Intel Xeon processors from 1.8 GHz to 2.4 GHz, with 512 KB of L2 advanced transfer cache packaged in a 603-pin micro-PGA (Pin-Grid Array). When two processors are installed, both processors must be identical. When only one processor is installed, the processor must be installed in the CPU1 socket, which is the socket closest to the corner of the server board. For a complete list of supported processors, see: http://support.intel.com/support/motherboards/server/SHG2 Memory The Intel Server Board SHG2 contains six 184-pin DIMM sockets. Memory is partitioned as three banks. DIMMs must be populated in identical pairs. The SHG2 server board supports up to six 2.5 V, ECC, DDR 200 or 266-compliant, registered SDRAM 184-pin gold DIMMs. A wide range of DIMM sizes are supported, including 128 MB, 256 MB, 512 MB, 1 GB, and 2 GB DIMMs. The minimum supported memory configuration is 256 MB, using two identical 128 MB DIMMs. The maximum configurable memory size is 12 GB using six 2 GB DIMMs. The SDRAM interface runs at a frequency of 200 MHz; however 266 MHz memory can be used. The memory controller supports 2-way interleaved SDRAM, memory scrubbing, single-bit error correction and multiple-bit error detection with Chipkill† capability that allows the system to continue to run even in the event of a multi-bit SDRAM failure. Memory can be implemented with either single-sided (one row) or double-sided (two row) DIMMs. ✏ NOTE Use DIMMs that have been tested for compatibility with the server board. Contact your sales representative or dealer for a current list of approved memory modules.
