Installing or removing jumpers: A jumper is a small plastic encased conductor that slips over two jumper pins. Some jumpers have a small tab on top that you can grip with your fingertips or with a pair of fine needle nosed pliers. If your jumpers do not have such a tab, take care when using needle nosed pliers to remove or install a jumper; grip the narrow sides of the jumper with the pliers, never the wide sides. Gripping the wide sides can damage the contacts inside the jumper, causing intermittent problems with the function controlled by that jumper. Take care to grip with, but not squeeze, the pliers or other tool you use to remove a jumper, or you may bend or break the stake pins on the board. Memory The SHG2 Server Board 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 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.
